Paste runtime bytecode and a relationship list for an offline graph.\n\nMethodology:\n- Proxy, implementation, beacon and upgrade controller come from the Smart Contract Upgrade Explorer tool (EIP-1967 / EIP-1822 / EIP-1167 / Safe / ZeppelinOS / EIP-7702 detection from storage slots and bytecode).\n- owner() and admin() are read with eth_call (a revert means the function does not exist or is restricted).\n- Deployer and creation transaction come from Sourcify (v2 API, fields=deployment) — only available for contracts verified on Sourcify. A deployer that has code is reported as a factory.\n- Token standards: ERC-165 supportsInterface for ERC-721 (0x80ac58cd) and ERC-1155 (0xd9b67a26); ERC-20 when totalSupply() and decimals() answer; name/symbol/decimals/totalSupply are read on-chain.\n- Offline: runtime bytecode is scanned for dispatcher selectors (PUSH4 … EQ) to infer ERC-20 / ERC-721 / ERC-1155 / Ownable / AccessControl, EIP-1167 clone targets and EIP-7702 delegation; your relationship lines are added verbatim.", "tags": [ "web3" ], "x-mcp-tool": "smart_contract_relationship_graph", "requestBody": { "required": true,
