About Sourcify
Sourcify is the decentralized smart contract verification service. It verifies that deployed bytecode matches source code, enabling anyone to read and trust smart contracts.
Unlike Etherscan verification, Sourcify is open source and decentralized. It stores verified sources on IPFS, making them permanently available. The service supports full and partial matching.
Sourcify is integrated into block explorers and development tools. Verify once, available everywhere. Critical infrastructure for smart contract transparency and the foundation for trustless contract interaction.
Frequently Asked Questions
Sourcify is smart contract source code verification. It confirms deployed bytecode matches the source code you claim. Open source and decentralized—stores verified code on IPFS.
Etherscan is centralized and chain-specific. Sourcify is decentralized, stores on IPFS, and works across chains. Verify once, available everywhere. Both are valuable—Sourcify is more open.
Full match: exact same compiler settings and metadata. Partial match: bytecode matches but metadata differs. Full match proves exact source; partial proves functional equivalence.
Use their web interface, API, or integrated tools (Hardhat, Foundry plugins). Upload source files and metadata. Verification is automatic if files match deployed bytecode.
Centralized verification can be censored or go down. Sourcify stores on IPFS—permanent and censorship-resistant. True transparency for smart contract trust.
