EVM_ABI_DECODE_CALLDATA @ 1.0.0

EVM calldata decoder

Decodes EVM transaction calldata with the ABI you supply: function name, 4-byte selector, canonical signature and every argument (uint/int as decimal strings, bytes as hex, addresses EIP-55, tuples and arrays preserved), plus whether the calldata is canonically encoded. Input: data (0x hex, up to 32 KiB) and abi (JSON ABI or human-readable signatures, up to 512 items) or signature. Example request: {"data":"0xa9059cbb000000000000000000000000111111111111111111111111111111111111111100000000000000000000000000000000000000000000000000000000000f4240","signature":"transfer(address,uint256)"}. Computed offline from your input only; no explorer lookup. Identical input is served from cache.
