Verifications Attestations
Attestations establish trust and credibility by enabling issuers to make claims, either onchain or offchain, about any quality about the recipient’s wallet address.
EAS Attestations
Coinbase Verifications leverages the Ethereum Attestation Service (EAS), an open-source base layer for making attestations. Attestations are issued on Base using EAS with ENS domain verifications.coinbase.eth.
This technology, paired with a credible issuer, can transfer credibility to the recipient. Because the attestation can be stored onchain, anyone can gather the attestation data from EAS.
Schemas
Schemas act as blueprints for attestations and define the structure and type of data for a specific type of attestation. They set the information requirements for the attestation to contain.
