- Real-world use case 01
Verifying transaction signatures
An auditor finds a suspicious transaction and asks their agent to decode the payload using decode_calldata_payload to see the recipient address.
- Real-world use case 02
Preparing test transactions
A developer needs to call a specific function and uses encode_function_call to generate the exact hex string for their testing script.
- Real-world use case 03
Identifying contract functions
You encounter an unknown transaction in Etherscan and use extract_function_selector to figure out which method was triggered.
