What Are Attestations?

Attestations are digital signatures on a structured piece of information. They play a critical role whenever you need to prove or verify something. EAS enables anyone to make attestations onchain or offchain about anything, fostering a more trustful and transparent world.

What is EAS?

Ethereum Attestation Service (EAS) is a public infrastructure for making attestations either onchain or offchain. It serves as a standard and base layer where any entity can make attestations about anything, providing a decentralized ledger for attestations.
