The desks

A desk is a page that does one job. Each one below says what you use it for, what the numbers are, and what it leaves out. The same introduction sits at the top of that desk. The pages are free, except Portfolio, which needs the account that stored the holdings. Nothing in this list writes a settlement unless the page says you are paying.

Prices

Prices come from CoinGecko when the page loads. The live tape also reads Bitcoin fees, Ethereum gas, the mood index, and the euro fixing. A 429 comes back as “busy, try again”, not as an empty market.

  • Live tape
    What you use it for
    Leave this tab open when you want prices, Bitcoin fees, Ethereum gas, and the mood index to refresh without reloading. Press Grab to pull immediately, or Pause when you do not want another request. Type a coin name to add it beside bitcoin, ether, and solana.
    What the numbers are
    Each pass asks CoinGecko, mempool.space, Blockscout, Alternative.me, and the ECB euro fixing. The clock is when that pass finished. The euro line names the fixing date Frankfurter published. The mood number is Alternative.me’s daily index.
    What it leaves out
    A source that misses stays blank and the reason is listed. The previous prices stay up with their own time until a later grab replaces them. This page does not store the rows and does not spend $ARCOP.
  • Markets
    What you use it for
    Open this when you want the large-cap board: price, market cap, and the day’s move. Search a name or ticker to replace the board with matches. Open a row for the longer chart.
    What the numbers are
    CoinGecko sends the price, cap, and 24-hour percent on each grab. While the tab is open the board asks again. Cap is price times circulating supply. The percent is that coin against its own price a day ago.
    What it leaves out
    An empty search stays on the largest coins. A busy response says to try again. It does not turn into an empty market, and none of these percents is a recommendation.
  • Sectors
    What you use it for
    Use this to see which CoinGecko categories are largest, and which large categories led or lagged today. Open the sector board from a search when the question is about a group rather than one coin.
    What the numbers are
    Each cap and the day’s percent come from CoinGecko’s category list. The percent is already a percent. Gainers and losers are only categories with at least $1 billion of cap, and only if the move is actually up or down.
    What it leaves out
    Categories overlap, so the caps must not be added into one market total. A day when no large category is up, or none is down, says so instead of filling the list with the smallest moves.
  • One coin
    What you use it for
    Open any coin from the board, or change bitcoin in the address to another CoinGecko id. Switch the line across 1 day, 7 days, 30 days, 90 days, and 1 year. From here you can jump to score, risk, the book, voices, or a comparison with bitcoin.
    What the numbers are
    The price, cap, volume, and day’s range are CoinGecko’s. The line is sampled prices over the range you picked. The percent on the line is the last sample versus the first.
    What it leaves out
    The line is not a forecast. If CoinGecko does not return that range, the chart says so. Bitcoin and ether also link to the on-chain day. Other coins do not have that day.
  • Book depth
    What you use it for
    Use this before you size an order. Search a coin and read the twelve largest books CoinGecko still marks as fresh: the venue, the pair, the spread, and the dollars they say would move that book about 2%.
    What the numbers are
    Price and volume are that venue’s converted dollar figures. The spread is already a percent. Cost to move up and cost to move down are CoinGecko’s own 2% figures for that book. A trade link opens only when they published an http address.
    What it leaves out
    Each row is one venue, not the whole market. Adding the twelve volumes does not equal the coin’s day volume. Stale books and books they flag as anomalies are dropped. A missing cost stays unpublished.
  • Coin risk
    What you use it for
    Type a coin you might buy. The report says how risky that coin looks on public market data, and it keeps refreshing while the tab is open. Pause when you do not want another request.
    What the numbers are
    Parts are scored from 0 to 100, higher meaning riskier: thin turnover, the day’s range, distance from the recorded high and the recorded low, dilution, size, the 7-day, 30-day, and longer moves, whether those windows agree, the last hour, and the largest book’s spread and 2% move cost. The headline is the average of the parts that came back. Price and volume are CoinGecko’s. The book is their largest fresh venue.
    What it leaves out
    A missing part is omitted, not scored as zero. The book is one venue and is reused for about 8 seconds. There is no holder list and no forecast. The number is not a buy or a sell, and it is not the quality score on the score desk.
  • Volatility
    What you use it for
    Open this before sizing a coin. It shows how wide the daily moves have been, how much of that width was downside, where the latest week sits on the path, the deepest close-to-close drop, and the best and worst day. For bitcoin and ether it also shows Deribit’s volatility index.
    What the numbers are
    Realized volatility is the sample standard deviation of daily log returns, times the square root of 365, as a percent. Downside uses only the negative logs. Week rank is how many 7-day windows were this calm or calmer, out of 100. A high rank is a wide week. The path is CoinGecko’s daily closes for about 90 days. Deribit’s index is their daily close. Their historical volatility is the latest point of the series they return.
    What it leaves out
    It describes the path that already printed. It is not a forecast and not an option price. Intraday lows can be deeper than the close-to-close drawdown. Deribit’s index is only attached for bitcoin and ether.
  • Correlation
    What you use it for
    Type two coins when you want to know whether their daily moves travelled together. Switch 30 or 90 days. Use it when a second coin is supposed to diversify the first.
    What the numbers are
    The number is the Pearson correlation of daily log returns on UTC dates both coins printed, and only when those dates are one day apart. Beta is how many times one coin’s daily log move lined up with the other’s. Same sign is the share of those days that moved the same way. Each realized figure uses that same set of pairs. 1 is lockstep, −1 is opposite, 0 is no straight-line relationship.
    What it leaves out
    A high number is not a hedge and does not say tomorrow will match. Missing days are dropped instead of stretched. Two names that resolve to the same coin are refused.
  • Coin score
    What you use it for
    Search a coin when you want one number built from the live read. The page averages the parts CoinGecko actually returned: depth, the day’s range, distance from the high and the low, supply already out, size, the week, the month, the longer move, and whether the week agrees with that longer window.
    What the numbers are
    Each part is scored from 0 to 100 on this request. The headline is the average of the parts that exist. Rank, price, and categories are shown beside it so you can see what went in.
    What it leaves out
    A missing part is omitted, not scored as zero. Ticker lookalikes are dropped when an exact coin is present. The number is not a recommendation and it is not a forecast.
  • Convert
    What you use it for
    Type an amount and two names when you want one coin in another coin, or in dollars. Use USD for dollars. Submit to read the prices.
    What the numbers are
    Both coins are priced from CoinGecko on that submit. The result is amount times the first price, divided by the second. A dollar side uses 1.
    What it leaves out
    Nothing converts until you submit. The page does not include trading fees, spreads, or the book on a venue. For a bag against an entry, use PnL.
  • PnL
    What you use it for
    Type how many coins you hold, the price you paid, and a fee percent if you paid one on the way in. The page prices the bag now and shows the gain or loss against that cost.
    What the numbers are
    The live price is CoinGecko’s. Value is amount times that price. Cost is amount times your entry, then plus the fee percent. Break-even is the entry after that fee. The result is value minus cost.
    What it leaves out
    A fee to get out is not included. Nothing is stored and no order is sent. Without an entry you only see the value now.
  • DCA
    What you use it for
    Type a coin and a dollar amount to see what buying that amount once each past day would have produced. Switch 7, 30, or 90 days. The same total spent on the first day is shown beside it.
    What the numbers are
    Each day uses the last CoinGecko sample on that UTC date. Coins bought are the dollars divided by that price. The average is dollars spent divided by coins received. The lump sum buys everything on the first day at that day’s price.
    What it leaves out
    The day count can be one longer than the button if today is already in the series. Fees are not included. The path already happened. It is not a schedule for later.
  • Compare
    What you use it for
    Type two coins when you want price, cap, volume, and the day’s range side by side. The page refuses a pair that resolves to the same coin.
    What the numbers are
    Both quotes are CoinGecko’s on this request, including the 7-day percent when they publish one. Each column is that coin’s own figures.
    What it leaves out
    A shared percent scale is not implied. One coin can be up on a tiny cap while the other is flat on a large one. This is not a trade between them.
  • Trending
    What you use it for
    Open this to see the coins people are searching on CoinGecko right now, rather than the coins that moved the most.
    What the numbers are
    The list is CoinGecko’s trending search list for this request, with the price and day’s move when a market quote comes back.
    What it leaves out
    Search interest is not volume and not a ranking by quality. A coin can trend on a thin book. If the list is empty, they did not return one.
  • Pulse
    What you use it for
    Open this for one read of the whole market: total cap, bitcoin’s share, ether’s share, and Alternative.me’s index with their label.
    What the numbers are
    Cap, volume, and the day’s move of the total come from CoinGecko’s global market. Share is that coin’s cap divided by the total. The index is Alternative.me’s number and their word for it.
    What it leaves out
    The index is their label, not a trade. The 30-day path of the index is on mood. DeFi’s share of the total is a different desk.
  • Portfolio
    What you use it for
    Sign in, type the coin and the amount you hold, and this page prices the bag. Add or remove rows. The holdings stay on your account.
    What the numbers are
    Each price is CoinGecko’s now. Value is price times the amount you typed. The day’s profit uses that value and the coin’s 24-hour percent. Concentration is the largest row divided by the total.
    What it leaves out
    The amounts are what you typed, not a wallet read. A coin CoinGecko does not price stays unpriced. This is not the public PnL desk, and it does not spend $ARCOP to display.

Arc, DeFi, and cash

DefiLlama numbers are deposits and stablecoin balances on the chains they track. Frankfurter is the ECB cash rate. None of these is the ARCOP balance on this ledger.

  • Arc chain
    What you use it for
    Open this for the chain DefiLlama names Arc: value locked, the protocols on it, and the stablecoins they place there. Use Arc mainnet when you want the live height and a USDC fee instead.
    What the numbers are
    Value locked, protocol totals, and stablecoin balances are DefiLlama’s, fetched when you open the page. The chain id on the page is the one they publish. The chart is their history of value locked.
    What it leaves out
    This is not the $ARCOP ledger and not the USDC in an Arcop account. Swap volume for this chain is on Arc swaps. Fees versus what protocols kept are on Arc flow.
  • Arc mainnet
    What you use it for
    Use this to see Arc chain 5042 right now: how fast blocks are landing, what a transfer costs in USDC, and to look up an address, a transaction, or a block. Add the network to a wallet from the button when you want to use it. Other coins on the same chain are on Arc tokens.
    What the numbers are
    Height, gas price, blocks, and lookups come from Circle’s mainnet RPC on this request. A plain transfer is 21,000 gas times that price, in USDC. An address shows native USDC, which pays gas, and the ARC token balance on the published contract. A transaction shows status and the fee from the receipt.
    What it leaves out
    The button only asks the wallet to add the network. It does not send a transaction. The ARC supply is the contract’s totalSupply, not a price, and it is not $ARCOP. The USDC here is not the USDC balance in an Arcop account.
  • Arc tokens
    What you use it for
    Search a symbol or a name to find an ERC-20 on Arc. The index keeps every coin that transferred in the blocks it has walked, not only the latest handful. Paste a contract address for a coin the walk has not reached yet. Add a wallet to read balances of the coins on screen.
    What the numbers are
    Names, decimals, and supply come from the contracts, through one multicall on the Arc mainnet RPC. Transfer counts are ERC-20 logs inside the indexed block range. A wallet balance is balanceOf. Native gas USDC is an 18-decimal account balance.
    What it leaves out
    The index grows backward from the chain tip. A coin that has not moved inside the reached blocks is missing until the walk gets there, or until you paste its contract. Supply is not a price. These balances are not $ARCOP and not the USDC in an Arcop account. Non-fungible transfers are left out.
  • Arc database
    What you use it for
    Query the Arc token index: a symbol or address, a minimum transfer count, named coins only, and a sort by transfers, supply, symbol, or the latest block seen.
    What the numbers are
    Counts are the transfers logged while the index walked backward from the chain tip. Supply and decimals come from the contract. First and last block are the span of transfers seen in windows that recorded a block number. The same rows are available as JSON from the API link on the page.
    What it leaves out
    The index is not the whole chain until the walk reaches older blocks. A coin with no transfer in the reached range is missing. A block span stays blank until a pass records one. This is not the $ARCOP ledger, and supply is not a price.
  • Arc coin
    What you use it for
    Paste an Arc token contract to read its supply, the transfers in the latest blocks, and the balances of the addresses that just moved it.
    What the numbers are
    Symbol, name, decimals, supply, and code size come from the contract on this request. Transfer counts, volume, and the address list come from that contract’s logs. Busiest side is the share of transfers that included one address on one side. The largest balance is that balance divided by supply, only among addresses that moved the coin. Indexed transfers are the count already stored in the Arc database.
    What it leaves out
    The log window starts at 160 blocks and shrinks if the chain refuses a wider read. Addresses that did not move the coin in that window are not listed. The balance share is not a holder ranking, and supply is not a price.
  • Arc holdings
    What you use it for
    Paste an Arc address to see native USDC and which of the busiest named coins that address currently holds.
    What the numbers are
    Native USDC is the account balance. Each other row is balanceOf on one of the eighty named coins with the most indexed transfers. Only non-zero balances are listed.
    What it leaves out
    A coin outside those eighty is not checked. A balance is the token amount, not a dollar value. This is not the signed-in portfolio and not an Arcop account.
  • Arc now
    What you use it for
    Leave this open when you want Arc mainnet as it moves: new blocks, native USDC changing hands, the newest transactions, and ERC-20 transfers from the last few seconds. The same tip and plain-transfer fee sit in the header on every page. Pause when you do not want another request.
    What the numbers are
    Each grab reads six recent blocks, the gas price, and transfer logs over the last 16 blocks from the Arc mainnet RPC. A fee on the tip block comes from the receipt. Token amounts use the decimals the contract reports. The clock is when that grab finished.
    What it leaves out
    Native USDC is the transaction value, so a token call often shows zero there. Fees are only filled for the tip block. A symbol that did not answer stays as an address. This is chain 5042, not the $ARCOP ledger and not an Arcop account balance.
  • Arc wallet
    What you use it for
    Paste an Arc address when you want that wallet’s gas balance, its ARC token balance, and the transfers that just touched it. Ethereum addresses stay on the Ethereum desk.
    What the numbers are
    Native USDC is the 18-decimal balance from the account. ARC is balanceOf on the published token contract. Token rows are ERC-20 logs where this address is the sender or the recipient. Native rows are transaction value in the newest blocks. In, out, and self say which side this address is on.
    What it leaves out
    The token window is the latest blocks, shortened when a longer read is too large. It is not a full history. Non-fungible transfers are left out. Native USDC here is not the USDC in an Arcop account, and the ARC token is not $ARCOP.
  • Arc receipt
    What you use it for
    Paste an Arc transaction hash to read that one receipt: status, the USDC fee, the method, and the ERC-20 transfers inside it.
    What the numbers are
    Status, gas, and the fee come from the receipt. The method is a known selector, or the first four bytes when it is not one of those. Token rows are the three-topic transfer logs on that receipt. Amounts use the decimals the token contract reports.
    What it leaves out
    A pending transaction has no fee and no logs yet. Non-fungible transfers are left out. The fee is USDC spent on gas, not a dollar conversion and not an Arcop charge.
  • Arc block
    What you use it for
    Paste an Arc block height to see the transactions in it, how full the gas limit was, and the base fee for a plain transfer.
    What the numbers are
    Hash, time, miner, gas used, gas limit, size, and base fee come from that block on the Arc mainnet RPC. Each transaction row links to its receipt. Native value is the transaction value field.
    What it leaves out
    The list shows up to 80 transactions. A taller block says how many were left off. Base fee is not the fee a transaction actually paid. That is on the receipt.
  • Arc active
    What you use it for
    Leave this open to see who is sending on Arc across the newest 30 blocks, and which addresses those transactions called.
    What the numbers are
    Each grab counts transactions by sender and by destination. Native USDC is the sum of transaction value. Gas fill is gas used divided by gas limit across the window. The tip base fee prices a 21,000-gas transfer.
    What it leaves out
    Token amounts are not in these totals. A hidden tab does not refresh. This is chain 5042 activity, not the $ARCOP ledger.
  • Arc allowance
    What you use it for
    Paste a token, the wallet that holds it, and the spender to see how much that spender can still move.
    What the numbers are
    The allowance and the owner’s balance are read from the token contract on Arc mainnet. Unlimited means the stored approval is at the top of the integer range. Decimals scale both numbers.
    What it leaves out
    The page only reads. Clearing the allowance is on Arc revoke. A contract that does not report decimals leaves the amounts blank. This is not an Arcop account balance.
  • Arc approvals
    What you use it for
    See ERC-20 approvals just written on Arc, and whether the spender can still move those coins. Paste an owner to limit the list to one wallet.
    What the numbers are
    Each row is an Approval log. The amount is what that log wrote. Allowance now is the current allowance for the same owner and spender. Still open means that current allowance is above zero. Cleared means it is zero.
    What it leaves out
    The window is the latest blocks, shortened if the chain refuses a wider read. Older approvals are absent. Clearing an allowance is on Arc revoke. A pair you want to check outside this window belongs on Arc allowance.
  • Arc pace
    What you use it for
    Open this to see how fast Arc blocks are landing, how full they are, and which calls those blocks contain.
    What the numbers are
    The twenty newest blocks come from the Arc mainnet RPC. Blocks per second is the gap between the newest and oldest timestamps. Fill is gas used divided by the gas limit. A named call is a known selector. Anything else is the first four bytes.
    What it leaves out
    Timestamps are whole seconds, so two blocks can share a second and show a gap of 0. This is one window, not a day of history. The tab asks again while it is open.
  • Arc calls
    What you use it for
    Open this to see which functions the newest Arc blocks are actually calling, and to read the token transfers inside a swap-style call.
    What the numbers are
    The forty newest blocks come from the Arc mainnet RPC. A name is a known selector, or a clean signature from the 4byte directory. A swap row is a call whose selector is a router or swap function, followed by the ERC-20 transfers in its receipt. Permit2 is named when that canonical contract is the target.
    What it leaves out
    Unnamed selectors stay as four bytes. A swap list shows the newest handful, and at most six transfers from each receipt. It is not a dollar price and not every hop drawn as a route. This is chain 5042, not the $ARCOP ledger.
  • Arc heat
    What you use it for
    Open this to see which Arc tokens are moving right now, not which ones moved the most in the whole index.
    What the numbers are
    Every ERC-20 transfer log in the newest blocks is counted by token. Senders and recipients are the unique addresses on each side. Volume is the sum of those amounts when the decimals are known.
    What it leaves out
    The window starts at 80 blocks and shrinks if the chain refuses it. A quiet coin can still have a large indexed history. Volume is a token amount, not a price. Non-fungible transfers are left out.
  • Arc gas
    What you use it for
    Open this to see who paid USDC for gas on Arc in the newest blocks, and which transactions reverted.
    What the numbers are
    Each fee is gas used times the effective gas price from the receipt, scaled as 18-decimal USDC. Payers are ranked by that sum. A reverted row keeps its hash, the caller, and the fee they still paid.
    What it leaves out
    The read starts at 12 blocks and shortens if the chain refuses the wider batch. A missing block is left out. This is not an Ethereum gas price and not a dollar conversion.
  • Arc trade
    What you use it for
    Use this to swap one Arc token for another at the Uniswap quote, from a wallet you control.
    What the numbers are
    The token list is pools seen in recent blocks, plus a contract you paste. v4 is quoted from the pool key in those swaps. v3 is quoted at four fee tiers. The larger output is shown. Approve, then swap. The router address is the Uniswap router for that venue.
    What it leaves out
    A pair that does not quote stays empty. The site does not hold tokens and does not add a fee. Gas is native USDC. Slippage is the percent you type, capped at 50. This is chain 5042, not the $ARCOP ledger.
  • Arc USDC
    What you use it for
    Buy or sell one Arc token for USDC on Uniswap v4. The signature happens in your wallet.
    What the numbers are
    The names are v4 pools that include the 6-decimal USDC token and traded in the newest blocks. Buy spends that USDC and receives the token. Sell does the opposite. The quote comes from the v4 quoter, including the pool’s hook. The wallet approves Permit2, then the Universal Router, then sends the swap.
    What it leaves out
    A token with no v4 USDC pool in this window is not listed. Gas is the 18-decimal native USDC, so spending the entire 6-decimal balance can fail. The site does not hold the coins and does not add a fee. This is chain 5042, not the $ARCOP ledger.
  • Arc pools
    What you use it for
    See the Uniswap price and what 1 USDC buys, then open the pair on Arc trade.
    What the numbers are
    Pools are keys seen in recent blocks. Spot is slot0, or v4 getSlot0. The buy line is a one-USDC quote of that pool. v3 shows token balances in the pool contract. v4 shows in-range liquidity, not dollars.
    What it leaves out
    A pool that has not traded in the scanned blocks is absent. A hook can make the received amount differ from the spot price. This is chain 5042, not the $ARCOP ledger.
  • Arc hooks
    What you use it for
    See which Uniswap v4 callbacks a hook on Arc runs, and which pools use it.
    What the numbers are
    The lowest 14 bits of the hook address are the callback permissions. The list is hooks inside Universal Router swaps in the newest blocks. Bytecode length is read from the address. A pasted address is decoded even when it did not trade in this window.
    What it leaves out
    A hook that has not been in a scanned swap is absent until you paste it. The bits say which callbacks are allowed, not the Solidity source. A delta callback can change the amount you receive. This is chain 5042, not the $ARCOP ledger.
  • Arc send
    What you use it for
    Send native USDC or an ERC-20 from your wallet.
    What the numbers are
    Native is 18-decimal transaction value. A token is an ERC-20 transfer. The list is pools just seen, or a contract you paste. Gas is still native USDC.
    What it leaves out
    The site does not hold the coins. Sending the entire native balance can fail for lack of gas. The 6-decimal USDC token is not the gas balance.
  • Arc worth
    What you use it for
    See what an address holds, priced in USDC where a pool exists.
    What the numbers are
    Balances are the top named indexed coins plus native gas USDC. A USDC price is the spot from a pool that just traded. The 6-decimal USDC token counts as one USDC. Native gas is shown beside that total and is not added in.
    What it leaves out
    A coin outside the top 80 or without a recent USDC pool is unpriced. The figure is spot times balance, not what a sale of the whole bag would clear. This is chain 5042, not an Arcop account.
  • Arc ladder
    What you use it for
    See what 1, 10, 100, and 1000 USDC buy of one token on Uniswap v4.
    What the numbers are
    Each row is a v4 quote of that exact pool, including the hook. The per-USDC line is that quote divided by the size.
    What it leaves out
    A size the quoter rejects is left blank. This is not a sell of the whole bag and not a v3 quote. Gas is still native USDC.
  • Arc revoke
    What you use it for
    Set an ERC-20 allowance back to zero, or clear the Permit2 allowance the Universal Router uses.
    What the numbers are
    The transaction is approve(spender, 0), or a Permit2 approve of amount 0. The signature is in your wallet.
    What it leaves out
    The page does not list every old approval. Recent approvals are on Arc approvals. The site does not hold the coins.
  • Arc units
    What you use it for
    See the gas USDC and the 6-decimal USDC token for one address, kept apart.
    What the numbers are
    Gas is the account balance, 18 decimals. The token is balanceOf on 0x3600…0000, 6 decimals. Both are read on this request.
    What it leaves out
    The two numbers are different pots. Do not add them. This is chain 5042, not an Arcop account.
  • Arc nonce
    What you use it for
    See how many transactions an address has confirmed, and how many this node still has in flight.
    What the numbers are
    Latest and pending are the two transaction counts the Arc RPC returns. In flight is pending minus latest. The next nonce to sign is the pending count.
    What it leaves out
    Pending is what this RPC has seen, not every node. A count is not a list of the waiting transactions.
  • Arc code
    What you use it for
    Check a contract’s bytecode and whether it answers like a token or an NFT before you approve it.
    What the numbers are
    Code size is eth_getCode. Symbol, name, decimals, and supply are the ERC-20 reads. ERC-165, ERC-721, and ERC-1155 are supportsInterface calls.
    What it leaves out
    A missing answer stays unreported. Interface bits are what the contract claims, not an audit. An address with no code is an account.
  • Arc one
    What you use it for
    Read one token balance for one wallet, including a coin the holdings index does not check.
    What the numbers are
    The balance is balanceOf on the contract you paste, scaled by the decimals that contract returns. A USDC spot is added only when a pool in the newest blocks quotes that token.
    What it leaves out
    No code means there is no token balance. No pool means no USDC figure. Spot times balance is not a sale quote.
  • Arc impact
    What you use it for
    See how many tokens a USDC size buys on Uniswap v4, and how that rate compares with 1 USDC.
    What the numbers are
    Both numbers are v4 quotes of the pool that just traded, including its hook. The percent is the gap in tokens per USDC.
    What it leaves out
    A size the quoter rejects is left blank. This is not a v3 quote and not a sale of a wallet. Gas is still native USDC.
  • Arc open
    What you use it for
    See if a wallet still lets Permit2, the Universal Router, or SwapRouter02 move one token.
    What the numbers are
    Three rows are ERC-20 allowances. The fourth is the Permit2 allowance for the Universal Router. Open means the stored amount is above zero.
    What it leaves out
    Other spenders are not listed. The page does not revoke. Clearing one is on Arc revoke.
  • Arc authors
    What you use it for
    See which account sealed the newest Arc blocks.
    What the numbers are
    Each row is the miner field on a block header. The ranking counts those 20 blocks.
    What it leaves out
    A block that omits the field is left unnamed. This is not a day of history and not a Bitcoin miner.
  • Arc pair
    What you use it for
    Put two Arc token contracts next to each other.
    What the numbers are
    Name, decimals, supply, and code size come from each contract. Indexed transfers are the count already stored. A USDC spot appears when a recent pool quotes that token.
    What it leaves out
    A coin the index has not walked shows zero indexed transfers. Supply is not a price. A missing spot stays blank.
  • Arc signature
    What you use it for
    Name the function in a selector, in calldata, or in one Arc transaction.
    What the numbers are
    A hash loads that transaction’s input. The name is the local map, or a clean signature from the 4byte directory. A native transfer has no selector.
    What it leaves out
    Spam signatures are dropped. An unknown selector stays as four bytes. The name is not proof of what the bytecode does.
  • Arc slot
    What you use it for
    Read one storage word from an Arc contract.
    What the numbers are
    The slot is a decimal number or a 0x hex word. The result is the 32 bytes at that slot. A word that is only an address is linked.
    What it leaves out
    Mappings and packed fields are not decoded. A zero word can be an empty slot or a real zero. This is chain 5042.
  • Arc born
    What you use it for
    See contracts that were created in the newest Arc blocks.
    What the numbers are
    A creation is a transaction with no destination. The new address is the contract field on the receipt. The byte count is the code at that address when the page was read.
    What it leaves out
    The window is 12 blocks, and at most 24 creations are listed. A contract created inside another call is not in this list. A zero byte count means the address has no code now.
  • Arc logs
    What you use it for
    Paste a contract to read the events it just emitted. Add a topic when you only want one event.
    What the numbers are
    Each row is one log: the block, the log index, the first topic, how many topics, the data size, and an address when the first data word is one. The receipt link opens that transaction.
    What it leaves out
    The window starts at 80 blocks and shortens if the chain refuses it. Forty logs is the maximum shown. Topics besides the first, and words besides the first address, stay undecoded.
  • Arc words
    What you use it for
    Paste calldata or a log’s data field when you want the 32-byte words as numbers.
    What the numbers are
    The split is done in the browser. Each word is an integer. An address appears when the first 12 bytes are zero. Text appears when the remaining bytes are printable.
    What it leaves out
    A short paste is padded with zeros, and the page says so. This does not name the function and does not ask Arc. A named call is on Arc signature.
  • Arc rug
    What you use it for
    Paste a token contract before you buy it. The page lists only the checks that came back from Arc and from the Uniswap quoter.
    What the numbers are
    Bytecode is searched for mint, owner, and pause selectors. owner() and paused() are called. Mint rows are Transfer logs from the zero address in the newest blocks. The round trip buys 1 USDC of the token on Uniswap, then asks the quoter to sell that amount back.
    What it leaves out
    A selector in the bytecode is not proof you can call it. A quiet result is not a certificate of safety. Mint history outside this window is absent. The USDC figure includes the pool fee and that size. It is not a tax rate and not a sale of a large bag. Nothing is signed from this page.
  • Arc flow
    What you use it for
    Open this to follow stablecoin dollars on the Arc chain over time, and to see fees collected there against the part protocols kept.
    What the numbers are
    Stablecoin history is DefiLlama’s chart for Arc. Fees and revenue are their daily overview for that chain. A change figure they already express as a percent is shown as a percent.
    What it leaves out
    DefiLlama’s Arc is chain 5042, not the $ARCOP ledger. Revenue is what they say protocols kept, not a payout on this site.
  • Chains
    What you use it for
    Start here to rank chains by value locked, then open one chain and read the largest protocols on it.
    What the numbers are
    The ranking and the protocol totals are DefiLlama’s on this visit. A chain page uses the name they publish.
    What it leaves out
    Value locked is deposits they track, not a market cap and not the ARCOP ledger. Arc’s own page is the shorter view of that one chain.
  • Stablecoins
    What you use it for
    Search a symbol when you want circulating supply and how far a dollar peg sits from $1. Coins that also sit on Arc are called out.
    What the numbers are
    Supply and price are DefiLlama’s. Only coins they mark as pegged to the dollar get a gap from $1. The day and week percents compare supply with their previous readings.
    What it leaves out
    A euro or pound coin is not judged against a dollar. Balances by chain are on chain stables. This list is not value locked.
  • Chain stables
    What you use it for
    Use this when the question is which chain holds the stablecoins, not which coin. The fifteen largest chains are listed. The headline total uses every chain with a balance.
    What the numbers are
    Each total sums the pegs DefiLlama places on that chain. The dollar-pegged line is only the pegged-USD slice. Share is that chain divided by the all-chain total.
    What it leaves out
    This is not value locked, not Arc alone, and not the coin-by-symbol page. Bridged dollars can sit on more than one chain, so the totals are not a count of unique holders.
  • Fiat
    What you use it for
    Type an amount and two currency codes to convert at the ECB rate Frankfurter publishes. The page lists the currencies they support.
    What the numbers are
    The rate and the date are Frankfurter’s latest fixing for that pair. The result is your amount times that rate.
    What it leaves out
    This is a daily central-bank fixing, not a live dealer quote. It does not tick with the coin tape.
  • Mood
    What you use it for
    Open this for the last 30 days of Alternative.me’s fear and greed index, with the word they attach to each day.
    What the numbers are
    The number runs from 0 to 100 on their scale. The label is theirs. The line is the values they returned for the window.
    What it leaves out
    The page repeats their label. It does not turn the index into a buy or a sell, and it is the whole market, not one coin.
  • Voices
    What you use it for
    Search a coin to read posts from its project community, a wider public search when that feed is empty, Hacker News, the market mood index, and a short sample of large transfers.
    What the numbers are
    Reddit comes from the project subreddit when CoinGecko lists one, otherwise a site search. Hacker News is a relevant search. Mood is Alternative.me’s whole-market index. Bitcoin’s sample is the newest block’s largest single outputs, excluding the coinbase, at or above 1 BTC. Ether uses Blockscout transfers at or above 10 ETH. Hyperliquid rows are recent prints, bid or ask.
    What it leaves out
    Posts are not a poll of holders. The transfer sample is not every large holder. Prints are trades, not named wallets, and small prints are not called whales. Follower counts are not invented.
  • Units
    What you use it for
    Convert sats, gas units, and unix time in the browser when you do not need a live price.
    What the numbers are
    The math stays on this page. A sat is one hundred-millionth of a bitcoin. Gas is the units you type. Unix time is seconds since 1970.
    What it leaves out
    Nothing here asks a price API. Dollar cost of a send is on the send-cost desk, which does use live prices.
  • Size
    What you use it for
    Type an account, a risk percent, an entry, and a stop to size a position. Type a price multiple to read impermanent loss on a 50/50 pool.
    What the numbers are
    Dollars at risk are the account times the percent. Units are those dollars divided by the distance from entry to stop. Impermanent loss compares the pool with holding both coins after one price becomes that multiple.
    What it leaves out
    Both are formulas in the browser. They do not look up a price and they do not place an order. Pool fees you earned are not in the impermanent-loss percent.
  • Arc swaps
    What you use it for
    Open this to see where the last day of DEX volume on the Arc chain actually happened, and each venue’s share.
    What the numbers are
    DefiLlama’s DEX overview for Arc supplies the 24-hour total and the venues. Share is that venue divided by the chain total.
    What it leaves out
    This is the chain they name Arc, not the $ARCOP ledger. Volume across every chain is the separate DEX volume desk.
  • DEX volume
    What you use it for
    Use this for the last day of DEX volume across every chain DefiLlama tracks, and the fifteen largest venues.
    What the numbers are
    The day, week, and change come from their DEX overview. A venue’s share is its day divided by the all-chain day. The change they publish is already a percent.
    What it leaves out
    Display names can repeat, so rows are kept distinct. This is not Arc-only volume and not value locked.
  • Fees
    What you use it for
    Open this to see what protocols collected and the slice DefiLlama files under Arc.
    What the numbers are
    The figures are their fees overview for the window the page requests. Arc is called out from that slice rather than mixed into a global total you would have to sum yourself.
    What it leaves out
    A fee collected is not revenue kept. Revenue kept on Arc is on Arc flow. None of this is a fee on the ARCOP ledger.
  • Funding
    What you use it for
    Use this to read Hyperliquid’s hourly perpetual funding, open interest, and day volume. The widest rates are limited to markets that actually traded.
    What the numbers are
    The rate is the hourly funding they publish. A positive rate means longs pay shorts. The year line is that hour times 24 times 365, shown as a scale, not a forecast. Markets under $100,000 of day volume are left off the wide-rate list.
    What it leaves out
    This is one venue. It is not Binance or Deribit. The year line is not a prediction that the rate will stay.
  • Funding carry
    What you use it for
    Use this when you want the funding a perpetual already charged, not only the hour that is on now. Pick bitcoin, ether, solana, or another Hyperliquid name, and 7 or 30 days.
    What the numbers are
    Each print is the hourly funding fraction Hyperliquid published. The average is those hours. Added up is the sum of the fractions, as a percent. Longs paid is the share of hours that were positive. Scatter is the sample deviation of those hours. The year figure repeats one hour 24 times 365. A positive rate means longs paid shorts.
    What it leaves out
    This is not a wallet balance and it ignores trading fees. A name Hyperliquid does not list comes back empty. The live hour, open interest, and day volume stay on the funding desk.
  • Futures
    What you use it for
    Switch bitcoin or ether to read Deribit’s futures: mark, the index, basis, and open interest.
    What the numbers are
    Basis is the mark minus the estimated delivery price, divided by the index. Open interest is the figure Deribit publishes for that book.
    What it leaves out
    This is Deribit only. Options on the same venue are a different desk. Basis is not a forecast of the spot price.
  • Options
    What you use it for
    Switch bitcoin or ether to see put and call open interest on Deribit, the put-to-call ratio, and the eight largest lines.
    What the numbers are
    Open interest is in the underlying coin, as Deribit reports it. The ratio is put open interest divided by call open interest. Mark IV is their number on that line. Day volume uses the dollar volume they publish.
    What it leaves out
    The eight lines are the largest by open interest, not every strike. Their dollar volume is the scale they publish, not a notional you should recompute. IV is not a forecast.
  • DeFi share
    What you use it for
    Open this to see how much of CoinGecko’s market they count as DeFi, and which coin leads that slice.
    What the numbers are
    DeFi cap, dominance, and the top coin come from CoinGecko’s decentralized-finance global endpoint on this request.
    What it leaves out
    Dominance is their classification, not a list of every protocol. Bitcoin’s share of the whole market is on pulse.
  • Exchanges
    What you use it for
    Use this to see assets DefiLlama ties to exchange wallets, and the day’s change. The list is the twenty largest.
    What the numbers are
    Assets, inflows, and the wallet link are theirs. The day’s change is the inflow they publish for that venue.
    What it leaves out
    This is wallet balances they attribute, not reported trading volume. Trading volume is on venue volume. Public-company treasuries are a different list.
  • Venue volume
    What you use it for
    Open this for reported spot volume and derivative open interest. Each list is the twelve largest venues in CoinGecko’s bitcoin unit.
    What the numbers are
    Spot volume is the 24-hour bitcoin volume they publish. Derivative open interest and volume are also in bitcoin. Trust is their 0 to 10 score.
    What it leaves out
    The unit stays in bitcoin. A dollar figure is not invented. Trust is not an audit. Wallet balances are on the exchange-assets desk.
  • Treasuries
    What you use it for
    Switch bitcoin or ether to see the public companies CoinGecko lists, how many coins they attribute, and the largest holders.
    What the numbers are
    Coins, dollar value, and share of supply are theirs. Entry cost is shown only when they publish a total entry value above zero. The headline counts every company. The list shows the fifteen largest.
    What it leaves out
    This is public companies, not every holder and not exchange wallets. A missing entry cost stays unpublished rather than estimated.
  • Incidents
    What you use it for
    Read recorded losses when you want the amount, the technique, and the chain from the public list this page uses.
    What the numbers are
    Each row keeps the fields the source published: how much, how it was described, and where.
    What it leaves out
    The list is a record, not a guide. It does not explain how to repeat anything, and a missing field stays missing.

Bitcoin and Ethereum

Bitcoin fees and blocks come from mempool.space. The on-chain day comes from Coin Metrics. Ethereum gas comes from Blockscout. Dollar figures use the CoinGecko price of the moment.

  • Bitcoin
    What you use it for
    Use this for the Bitcoin fee you would pay, the latest blocks, and a lookup. Paste a height, a 64-character txid or block hash, or an address.
    What the numbers are
    Fees and blocks come from mempool.space. An address shows confirmed and mempool balances. The line under the fees compares the hour rate with the floor of the projected blocks. Dollar figures use the CoinGecko price of the moment.
    What it leaves out
    A mempool amount is not confirmed. The next-block line is a projection. Daily addresses and exchange flows are on the on-chain desk, not here.
  • On-chain
    What you use it for
    Switch bitcoin or ether to read the latest finished on-chain day: active addresses, transactions, MVRV, supply, and exchange inflow versus outflow.
    What the numbers are
    Coin Metrics supplies the daily series. The headline day is the latest one with MVRV and both flows filled in. That MVRV is also set against the median of the days in the pull. Net flow is outflow minus inflow, and the page counts how many of those days left the labeled exchanges. A later day can already have addresses before the rest is published.
    What it leaves out
    These are daily totals, not a live mempool. Exchange flow covers the wallets they label, and a flash day can still be revised. MVRV is market cap over realized cap. It is not a buy or a sell.
  • Halving
    What you use it for
    Open this for the live Bitcoin height, the subsidy now, how many blocks remain until the next cut, and Lightning capacity.
    What the numbers are
    Height, hashrate, and difficulty come from mempool.space. The subsidy halves every 210,000 blocks from a start of 50. The day count is blocks left times ten minutes.
    What it leaves out
    Ten minutes is the target, not a promise, so the date moves. The month of daily hashrate is on the hashrate desk. Fees miners earn are not inside the subsidy.
  • Hashrate
    What you use it for
    Use this for Bitcoin’s hashrate now and the month of daily averages, including how far the last average sits from the first.
    What the numbers are
    The current hashrate and difficulty are mempool.space’s latest readings. The line is their daily averages. The percent is the last average versus the first. Up means the last average is at least the first.
    What it leaves out
    The end of the line is the latest daily average, not the hashrate right now. Those two numbers are both shown because they differ. The percent is not a forecast.
  • Miner take
    What you use it for
    Open this to see how much of the latest Bitcoin block rewards came from fees rather than the subsidy.
    What the numbers are
    mempool.space’s reward stats cover the window, by default the latest 144 blocks. Fee share is fees divided by fees plus subsidy.
    What it leaves out
    The window is the recent blocks they summarize, not a miner’s private books. Pool names for the week are on the mining-pools desk.
  • Mining pools
    What you use it for
    Use this to see who found Bitcoin’s blocks over the last week and how concentrated that was.
    What the numbers are
    mempool.space’s one-week pool list supplies blocks found. Share is that pool’s blocks divided by the blocks in the window.
    What it leaves out
    A pool name is who they attribute the block to. It is not a list of every hashrate renter. The month hashrate path is a different desk.
  • Mempool
    What you use it for
    Open this to see how many Bitcoin transactions are waiting and which fee band the bytes sit in.
    What the numbers are
    Count, virtual size, and total fees are the mempool mempool.space sees. Each band is virtual bytes whose fee rate falls in that range.
    What it leaves out
    Fees attached are the sum already on waiting transactions, not the fee for a new one. How those bytes pack into the next templates is on next blocks.
  • Next blocks
    What you use it for
    Use this to see how mempool.space packs waiting transactions into the blocks it expects next. Place 1 is the next template.
    What the numbers are
    Each row has a median fee, a transaction count, the fees in that template, and the low-to-high fee range. The range uses the lowest and highest rate in the template.
    What it leaves out
    Miners can pick a different set. New transactions arrive and some drop. The next confirmed block can differ from place 1. This is not a promise of the next confirmation.
  • Gas lanes
    What you use it for
    Compare a plain transfer on Arc, Ethereum, Base, Arbitrum, Optimism, and Polygon. Change the gas units if the transaction is larger than a simple send.
    What the numbers are
    Arc’s fee comes from the chain 5042 gas price and is already USDC. The other rows use each chain’s Blockscout gas price times the token price that endpoint publishes.
    What it leaves out
    A chain that does not answer is marked on its own row. Arc can fail separately from Blockscout. The figure is a plain transfer at the average they publish, not a quote from a wallet.
  • Ethereum address
    What you use it for
    Paste an Ethereum address to read the balance, whether it is a contract, and the latest transactions Blockscout returns.
    What the numbers are
    Balance, contract code, and transactions come from Blockscout on this request. A contract is an address with code.
    What it leaves out
    The transaction list is the latest they return, not a full history. Internal transfers they do not include stay absent. This is not an Arc address. Arc addresses are on Arc wallet.
  • Send cost
    What you use it for
    Type a Bitcoin virtual size and a gas amount to see what that send would cost on Bitcoin, Ethereum, and Arc right now.
    What the numbers are
    Bitcoin fees are mempool.space’s hour and fastest rates, times your vbytes, times the CoinGecko bitcoin price. Ethereum uses Blockscout gas and the ether price. Arc uses the same gas units against the chain 5042 gas price, and the result is USDC.
    What it leaves out
    The default size is a typical simple payment. A larger or smaller transaction needs the number you type. Arc’s fee is the USDC you would spend on gas, not a dollar conversion and not an Arcop balance.
  • Gas
    What you use it for
    Read Ethereum slow, average, and fast, then type gas units to price that transaction.
    What the numbers are
    The three speeds are Blockscout’s. Cost in ether is units times the gwei price. Dollars use the ether price they publish.
    What it leaves out
    Speeds are that endpoint’s snapshot. A busy or failed read says so. Other chains are on gas lanes.

Writing and code

Each row keeps the public URL it came from. Open that URL before you treat the summary as the source.

  • News
    What you use it for
    Open this for the newest headlines from CoinDesk, The Block, Cointelegraph, Decrypt, and Bitcoin Magazine. Each line links to the publisher.
    What the numbers are
    Title, time, and the short line underneath are taken from that outlet’s feed. The list keeps the twenty-four newest items, at most eight from each feed.
    What it leaves out
    The words are theirs. Open the link before you treat the line as the story. A feed that misses is named, and the others still show. This is not the scored briefing search.
  • Briefing
    What you use it for
    Search once across news, code, Reddit, and Wikipedia when you want rows scored and kept with their source URL. Sign in if you want to pay to collect or train on them.
    What the numbers are
    Each row keeps the public URL, a quality score from the source’s own metric, and a reliability score. Markets, the chain, and Wikipedia start higher than Reddit. Training later keeps rows at reliability 40 or above as the answer index.
    What it leaves out
    The free page does not spend $ARCOP. Paying is a separate step. An empty paid fetch is not charged. Open the source URL before you treat a summary as the source.
  • Today
    What you use it for
    Open this in the morning for movers, the cost of a plain ether transfer, Hacker News, and repositories from the week.
    What the numbers are
    Gainers are coins up on the day. Losers are coins actually down, not the smallest gains. Gas is a plain Ethereum transfer. Posts and repos are the public items those sources returned.
    What it leaves out
    The mover lists are a slice, not every coin. A source that misses is named. This is not the full news wire.
  • Repo
    What you use it for
    Type owner/repo to read stars, open issues, the language, and the last push for that GitHub repository.
    What the numbers are
    The fields are GitHub’s on this request. The link opens the repository. A search that looks like owner/repo can jump here from the search desk.
    What it leaves out
    Private repositories you cannot see stay invisible. Stars are not a code review. The account behind several repos is the developer desk.
  • Developer
    What you use it for
    Type a GitHub username to see the account and the repositories it pushed.
    What the numbers are
    The profile and the repository list are GitHub’s. Push time is the timestamp they publish.
    What it leaves out
    What you see is what that API returns for a public account. It is not a full contribution graph, and it is not an audit of the code.
  • Status
    What you use it for
    Open this to see which sources answered just now and how long they took. Use it when a desk looks empty and you want to know if the source is up.
    What the numbers are
    The first six probes are the briefing sources. The rest are DefiLlama, Deribit, Hyperliquid, Alternative.me, Frankfurter, and Blockscout. A row shows a short sample from the answer.
    What it leaves out
    A down row is this visit only. It does not retry forever, and a busy CoinGecko on one desk does not by itself mark the whole site down.

The ledger, still free to read

These pages only read settlements already written here. They do not call the price APIs and they do not charge.

  • Ledger
    What you use it for
    Filter every ARCOP settlement by kind, text, age, amount, handle, or block when you want the receipt rather than a price.
    What the numbers are
    Rows are settlements already written on this ledger. Amounts are ARCOP or USDC as the row recorded them. A block height here is an ARCOP block.
    What it leaves out
    This page does not call the price APIs and does not charge. It cannot show a payment that was never written. Bitcoin and Arc blocks are different ledgers.
  • Audit
    What you use it for
    Open this to recompute every block hash and check that balances, stake, rewards, and burns still add up.
    What the numbers are
    The check walks the stored chain. Issued ARCOP is the genesis reserve plus faucet credits. Held is accounts, stake, pools, treasuries, rewards, and burns. A gap of zero means those pots match.
    What it leaves out
    A gap is reported rather than repaired on this page. USDC is checked on its own pots. Sessions and search holds are not ledger rows.
  • Chain
    What you use it for
    Use this for the ARCOP chain in the open: height, the newest blocks, and the mix of settlement kinds.
    What the numbers are
    Height and rows are counted from the ledger on this load. The hash line says whether the chain recomputed. Kind filters limit which rows you see.
    What it leaves out
    Nothing here is a hardcoded supply. It is not Arc chain 5042 and not Bitcoin. Querying a single block is the height link on a row.
  • Search
    What you use it for
    Type a coin, an Arc symbol or 0x address, a question, a repo, or a Bitcoin height, txid, or address. The page opens the matching desks and the public rows it can actually fetch.
    What the numbers are
    A 0x token address is read from that contract on Arc mainnet: name, decimals, supply, and whether bytecode is there. The transfer index is also searched, but a contract does not have to be in it. Prices, categories, and exchanges come from one CoinGecko search. Protocols, chains, stables, and hacks come from DefiLlama. Headlines are the current RSS items that contain your words. Wikipedia, Hacker News, GitHub repositories, GitHub accounts, npm, and Reddit use their own search. Papers come from OpenAlex. Questions come from up to three Stack Exchange sites. A Bitcoin-shaped query reads mempool.space.
    What it leaves out
    Empty live results stay empty. A busy source says so and is not treated as zero matches. A symbol search still only sees coins the index has walked. An address with no bytecode is not called a token. An ARCOP block height is labeled separately from a Bitcoin block. The search does not spend $ARCOP until you choose a paid collect or train.
  • $ARCOP
    What you use it for
    Read this to see what $ARCOP pays for on this site and how much is in accounts, stake, sponsor pools, and burns right now.
    What the numbers are
    The counts are summed from the ledger: faucet credits, balances, active stake, pool balances, and burned coins. The fee for a transfer, a handle, and a sponsor minimum are the constants the app uses.
    What it leaves out
    $ARCOP is the unit this app settles in. It is not the ARC token on Arc mainnet, and it is not listed on the Arc TVL page. Sending it does not move coins on Ethereum or Bitcoin.

How a scored row is labeled

  • Quality grows with the source’s own metric: market cap, points, stars, or words.
  • Reach uses a second metric, such as comments or open issues.
  • Sentiment on a coin follows the 24-hour percent. On a post it is a small word list in the title.
  • Reliability starts higher for markets, the chain, and Wikipedia than for Reddit. Training drops rows under 40.
