TraceFast live Ethereum data
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
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
