TechFlow reports that Gitcoin Passport has announced the launch of Onchain Stamps, enabling Gitcoin Passport holders to now transfer their Passports on-chain and seamlessly integrate with the Ethereum ecosystem.
Onchain Stamps are built on the Ethereum Attestation Service (EAS) and will initially be available on the OP mainnet, with plans to expand Gitcoin Passport to other EVM-compatible chains. Through interoperable attestations, projects can select relevant proofs to resist Sybil attacks and enable authorization.
