22 Services from x402-audit.tatschluizguilherme.workers.dev

Returns block metadata — number, hash, timestamp, baseFee, gas usage, transaction count, proposer, and size — for any block on Base, Optimism, or Ethereum Mainnet

Computes EIP-712 domainSeparator, hashStruct, and final digest from typed data, and optionally recovers the signer address via ecrecover — all offline with no RPC or API key

Computes the 4-byte function selector or 32-byte event topic0 from a human-readable Solidity signature using Keccak-256, with no RPC or API key required.

Returns complete transaction details for a given tx hash on Base, Optimism, or Ethereum Mainnet: raw tx data, receipt, decoded function call, event summary, gas costs, and confirmations in one call

Returns a comprehensive one-call wallet snapshot including native ETH balance, curated and custom ERC-20 token balances, USD prices, and total wallet value across Base, Optimism, or Ethereum Mainnet

Performs a comprehensive on-chain safety audit of an ERC-20 token on Base, returning a 0-100 safety score plus verdict covering honeypot simulation, buy/sell/transfer taxes, liquidity, holders, source verification, proxy status, and owner renouncement.

Returns on-chain receipt details for a given transaction hash on Base — including success/reverted status, block number, gas used, from/to addresses, value, and log count

Returns the native ETH or ERC-20 token balance of any wallet address on Base, Optimism, or Ethereum Mainnet, including decimals, formatted value, and current block number — without relying on a block explorer API.

Returns spot USD price, circulating supply, and market cap for up to 30 ERC-20 tokens on Base, computed on-chain from the most liquid DEX pool (Uniswap V3 or Aerodrome V2)

Discovers all Uniswap V2 and V3 liquidity pools for any ERC-20 token across Base, Optimism, and Ethereum Mainnet, returning per-pool pricing, liquidity, and reserve data computed directly on-chain.

Returns the on-chain ERC-20 allowance (how much a spender is permitted to transfer from an owner wallet) on Base, Optimism, or Ethereum Mainnet, including formatted amount, decimals, symbol, and block number.

Decodes raw Ethereum transaction calldata (hex) offline, returning the 4-byte selector, matched function name, typed named arguments, and nested sub-call decoding — no RPC or API key required.

Resolves ENS names to Ethereum addresses (forward) or Ethereum addresses to ENS names (reverse) across Mainnet, Base, and Optimism via on-chain registry lookup

Fetches full ERC-20 transfer history (incoming and outgoing, all tokens) for any wallet address on Base, Optimism, or Ethereum Mainnet, with decoded transfer details and native ETH balance delta.

Simulates an EVM transaction via eth_call on Base, Optimism, or Ethereum Mainnet before submission, returning success/failure, return data, decoded revert reason, and gas estimate

Fetches raw and decoded EVM event logs for any contract or wallet across Base, Optimism, or Ethereum Mainnet, with best-effort decoding of Transfer, Approval, and Uniswap V3 Swap events

Returns native ETH balances, gas estimates, and recent transactions for a wallet address across Optimism, Base, and Ethereum Mainnet in a single call

Returns swap quote (amountOut, spot price, price impact, minOut slippage guards) for any ERC-20 pair on Base using Uniswap V3 or Aerodrome V2 pool reserves

Returns live gas prices (gasPrice, maxPriorityFee EIP-1559) and latest block number for Base, Optimism, and/or Ethereum Mainnet via public RPCs.

Executes up to 20 read-only Ethereum calls in a single batched request via the Multicall3 contract on Base, Optimism, or Ethereum Mainnet, returning per-call success flags, return data, block number, and gas estimate

Generates a complete selector map from a contract ABI — 4-byte selectors for functions/errors and 32-byte topic0 for events — entirely offline with no RPC or API key required

Encodes EVM function calls (by name or 4-byte selector + JSON arguments) into raw ABI-encoded calldata hex, with built-in round-trip decode verification, requiring no RPC or API key.
