Api Endpoint

TraceFast

TraceFast knowledge graph: what an Ethereum address is, as proven facts — wallet or contract, proxy and upgradeable or not, a token and its standard, and for a token contract whether it can pause, mint or blacklist and whether it ever did. Each fact names the block it was evaluated at; an absent fact is not proven. Ethereum mainnet only. Path address: 0x-prefixed, 40 hex. Attribute dictionary: https://docs.tracefast.xyz/api/address-attributes.md
