Onchain Verify | Coinbase - Coinbase Verifications leverage the Ethereum Attestation Service to enable the issuance of Coinbase-verified, onchain attestations. Initially, you’ll be able to verify that you have a valid Coinbase trading account (also optionally your country of residence). These verifications can be tied to any self-custodial Ethereum (aka “EVM”) wallet address and are non-transferrable to other addresses. Once verified, you can use your verified wallet address to access onchain services and benefits that require having a verified status.
