Ethereum Signature Database
Business Profile
Core Value Proposition
4byte.directory provides the Ethereum Signature Database, which maps Ethereum function signatures (first four bytes) and event signatures (32-byte Keccak hashes) to their human-readable representations.
Target Customer
{"Blockchain developers","Ethereum smart contract developers","API engineers","Security researchers"}
Key Differentiator
Free to use with no licensing restrictions, permissive data reuse, and a large, searchable dataset (1,414,682 signatures) with an API and data-submission features.
Implementation Timeline

Pain Points
- 1Hard-to-interpret raw 4-byte and 32-byte Ethereum signatures without a mapping to human-readable names.
- 2Risk of service disruption or heavy load when using the API; scraping is allowed but should be done with limited concurrency or by running a local copy.
- 3Lack of an out-of-the-box, centralized solution for decoding signatures across multiple contracts without a dedicated database.
Key Features
- 1Function Signatures mappings
- 2Event Signatures mappings
- 3Submit Signatures
- 4Submit ABI
- 5Submit Solidity Source File
- 6API Docs
- 7Search Signatures (Bytes4)
Target Customer Industries
Competitive Advantages
- 1No license restrictions on data usage
- 2Large dataset (over 1.4 million signatures)
- 3Encourages and supports data scraping and local copies
- 4Public API and submission capabilities
