eth_decode_log
Decode a raw event log (topics + data) into named fields using a provided ABI on Ethereum mainnet. Pure computation — no RPC call needed. Pass topics and data from a transaction receipt log entry.
mezo_decode_calldata
Decode raw calldata into function name and typed arguments using a provided ABI on Mezo. Pure computation — no RPC call needed. Pass the hex calldata from a transaction input or eth_call.
mezo_decode_return
Decode raw return data from an eth_call into typed values using a provided ABI and function name on Mezo. Pure computation — no RPC call needed.
mezo_decode_log
Decode a raw event log (topics + data) into named fields using a provided ABI on Mezo. Pure computation — no RPC call needed. Pass topics and data from a transaction receipt log entry.
eth_encode_calldata
Encode a function call into ABI-encoded calldata hex. Accepts either a human-readable function signature (e.g. 'transfer(address to, uint256 amount)') or a full ABI JSON array plus function name. Pass uint/int values as decimal strings to avoid JS number precision loss. Pure computation — no RPC call needed.
eth_multicall
Batch multiple read-only contract calls into a single RPC round trip via Multicall3 on Ethereum mainnet (0xcA11bde05977b3631167028862bE2a173976CA11). Returns success status and raw return data for each call. Use allowFailure=true to prevent one failed call from aborting the whole batch.
