onyx_base_contract_verify
InactiveTool of onyx-paid-mcp
declared in 1.28.0
Contract verification + ABI metadata for any Base address. Returns is_verified, contract name, compiler version, language, optimization, ABI entry count, license, source code size. Auto-detects EIP-1967/OZ/UUPS proxies and resolves to the implementation contract. Backed by Blockscout (free, no auth). Use before any swap or interaction — unverified contracts are an instant red flag. (price: $0.002 USDC, tier: metered)
