The contract repository is periodically updated and pinned to the IPFS.

The repo is accessible under the following IPNS DNSLink names:

You can also access the contract repository with the /ipns/:ipns/contracts/:match/:chainId/:contractAddress format on IPFS. Example:

The repository interface is at and (unstable).

However for performance reasons, it is not possible to navigate the folders above the contract level. You need to know ahead the contract you are looking for.


Instead of entering the chain, you can check an address over all chains at

The contracts are accessible under the following path format:
  • :match: either full_match or partial_match
  • :chainId: EVM chain id 1 for Ethereum Mainnet, 5 Ethereum testnet Görli etc. See
  • :contractAddress: e.g. 0x5ed4a410A612F2fe625a8F3cB4d70f197fF8C8be

S3 Bucket

We also backup our repo at an S3 Bucket. We enabled the "Requester Pays" feature ( ) on the s3 Sourcify bucket.

mkdir contracts
cd contracts
aws s3 cp --request-payer requester --recursive s3://sourcify-backup-s3/stable/repository/contracts/ .
