Verified contracts are stored in the Sourcify repository and are available via Web or IPFS.
You can fetch the Repository statistics, returning a list of the count of
partial_match for each chain calling https://repo.sourcify.dev/stats.json
The contract repository is periodically updated and pinned to the IPFS. Shout out to web3.storage, estuary.tech for providing pinning for our public repository and also @wmitsuda for the troubleshooting and pinning of our repo!
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:
Pin the IPFS repository
Pin and help us decentralize the Sourcify repository!
Refer to the guide by @wmitsuda
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.
You can paste the contract address in the UI sourcify.dev without choosing the chain and it will check the contract on all chains in the contract repository
The contracts are accessible under the following path format:
:chainId: EVM chain id
1for Ethereum Mainnet,
5Ethereum testnet Görli etc. See chainlist.org
