Api Endpoint

TraceFast

TraceFast live Ethereum data: one deployed contract — the hash and size of its current code, what the code exposes (ERC-20 view functions, ERC-165, an EIP-1167 minimal proxy and its target), the proxy pattern detected in it, and its lifecycle: the deploying account, the origin account, the creating transaction, code changes and self-destruction. Path address: The contract address, `0x`-prefixed, 40 hex characters, any case. Docs: https://docs.tracefast.xyz/api/contract.md
