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.
