Signature Database

We also build an Ethereum signature database from our verified contracts. When you verify a contract, the function, event, and error signatures are extracted from its ABI and stored in the database.

The data is stored in the same database as the verified contracts. The signatures table holds the signature in text and their keccak256 hashes. The compiled_contracts_signatures holds the mappings of signatures to compilations in a many-to-many relationship.

• Schema: Check docs/repository/sourcify-database/#schema for the schema.
• API: Check docs/api/ for the API.
• Download: You can download the related tables in Parquet format from export.sourcify.dev. See /docs/repository/sourcify-database/#download for more details.
• Playground: Visit 4byte.sourcify.dev to search for signatures.
