Offline ABI selector generator (chain-agnostic, no RPC): human function signature in (transfer(address,uint256), optional parameter names, arrays address[], tuples (bytes,address,uint256,uint256)) and the 4-byte selector out, with full keccak256, parsed inputs and a round-trip verification against the /decode dictionary (verify.known); kind=event switches to the 32-byte topic0 (Transfer/Approval/Swap/Sync/Paused...). Pure cryptography: no RPC, no explorer, no API key, instant response, 100% margin
