TraceFast knowledge graph
TraceFast knowledge graph: the relations an address was the subject of at the end of one block — which implementation a proxy pointed at, which beacon it read, who administered it, where an account had delegated — each with the window it held for. Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query block: The block to answer about. Docs: https://docs.tracefast.xyz/api/address-relations-at-block.md
