4Byte

Explore Ethereum's comprehensive 4-byte signature database by Snake Charmers.

Welcome to the Ethereum Signature Database, where you can access a vast collection of function and event signatures. Our database currently boasts over 1,356,399 signatures and continues to expand. This free resource allows developers to easily convert byte signature search results into their corresponding human-readable forms, facilitating efficient searching and web scraping. The signatures, derived from the first four bytes of the Keccak hash of function and event signatures, provide crucial mappings for smart contract interactions. Feel free to explore, submit your signatures, and utilize our API with minimal restrictions to enhance your Ethereum development experience.
