Tools

contract_abi ~317 tokens
The verified ABI of a smart contract on Ethereum, Base, Arbitrum, Optimism or Polygon from Sourcify's open verification repository: contract name, compiler, match quality, every function and event signature, the full ABI, and for proxies the implementation contract with its ABI. Optional source=true
evm_checksum ~232 tokens
Validate an EVM address and return its EIP-55 checksummed form, saying whether the input was all lower case, all upper case, correctly checksummed or mixed case with a wrong checksum (a likely typo). Works for every EVM chain. Use before sending funds or storing an address; for whether it is a contr
evm_decode_calldata ~282 tokens
Decode EVM transaction calldata into the function and its arguments with viem: give the function signature (transfer(address,uint256)), or leave it out to try common ERC-20, ERC-721, ERC-1155, WETH, permit and multicall functions by selector. Numbers come back as decimal strings. Use to read what a
evm_verify_signature ~330 tokens
Verify an Ethereum personal_sign (EIP-191) signature: recover the address that signed a message and, given an expected address, say whether it matches. Works for ordinary wallets (EOAs); smart-contract wallets sign by ERC-1271, which this offline check does not cover. Use for sign-in-with-wallet, pr
keccak ~184 tokens
Keccak-256 hash (the Ethereum hash) of text or of 0x hex bytes, as used for function selectors, event topics and storage slots. Use when building or decoding EVM calls. Example: text=transfer(address,uint256). Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.
network ~214 tokens
Reference facts for paying and reading on Base mainnet: chain id, native USDC contract and decimals, block explorer and public RPC URLs, and the x402 network identifier. Use to configure an x402 or Base client. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free
stablecoin_supply ~224 tokens
Live total supply of USDC and USDT on Ethereum, Base, Arbitrum, Optimism and Polygon, read from each token contract (totalSupply), per network and summed per token, plus the grand total. A network whose nodes do not answer is listed with an error instead of failing the call. Use to track stablecoin
uniswap_pool ~298 tokens
Uniswap v3 pools for a token pair on Ethereum, Base, Arbitrum, Optimism or Polygon, read live from the factory and each pool: pool address per fee tier (0.01%, 0.05%, 0.3%, 1%), price of each token in the other, current tick, in-range liquidity and both token balances held, deepest pool first.
