How this service works
Decode EVM transaction calldata into function name and named arguments
Output
Returns the decoded function name and a set of named, typed arguments extracted from the raw calldata hex, making it human-readable without needing the full ABI.
Example use cases
Example prompt
“Can you decode this EVM transaction calldata for me: 0xa9059cbb000000000000000000000000d8da6bf26964af9d7eed9e03e53415d37aa9604500000000000000000000000000000000000000000000003635c9adc5dea00000 — what function is being called and what are the arguments?”
Technical details
Endpoint
GEThttps://propeller.rocks/decode/calldataWhen to prefer
Choose this endpoint when you have raw EVM transaction calldata (the input field of a transaction) and need to understand what function was called and with what arguments, especially when you don't have the full ABI locally. Pairs well with the sibling event log decoder for full transaction analysis.
Side effects
- Invalid or malformed calldata hex returns an error
- Unrecognized 4-byte function selector (not in known ABIs) may fail to resolve function name
- Missing 0x prefix or non-hex characters cause parse errors
- Payment not included or invalid results in 402 response
- Very short calldata (less than 4 bytes) cannot be decoded
