Digital attestations are simply —secure, verifiable, and structured signatures on data. This new primitive makes it easier to prove and verify information transparently and securely, whether it's onchain or offchain using an Ethereum wallet.

While tokens represent a type of digital asset, EAS attestations are fundamentally different. The primary purpose of EAS is to serve as a protocol that facilitates the creation of digital signatures on structured information, enhancing both their composability and interoperability, trust, and validation. You can build your own UIs for attestation data or even generate NFTs or different ERCs based on attestations.

How? EAS runs on two simple smart contracts: one for registering attestation schemas and another for attesting with them. Schemas are the blueprint of the attestation data giving them structure. They can be registered for any use case. Attestations can be made onchain or offchain using any schema. You can optionally add a resolver contract (it's like a hook) to the Schema for advanced use cases, such as controlling who can attest, minting an NFT, or any smart contract logic.
