According to Foresight News, Gitcoin Passport has announced the launch of Onchain Stamps, allowing Passport holders to transfer their Passports on-chain and seamlessly integrate with the Ethereum ecosystem. Onchain Stamps is built on the Ethereum Attestation Service (EAS) and will initially be available on the OP mainnet. Plans are in place to expand Gitcoin Passport to other EVM-compatible chains. Through interoperable attestations, projects can choose relevant attestations to resist witch attacks and authorization.
