Attestation Masterclass
summary
Workshop explains how the Ethereum Attestation Service (EAS) actually works and how to build with it: register reusable schemas, attach resolver contracts to enforce minting or access rules, issue onchain or offchain attestations with EIP-712 signatures, and use private data Merkle proofs to selectively reveal fields. EAS already has ~14,000 testers, >1,000 schemas and ~540,000 attestation recipients, plus native predeploys on the OP stack and Base for faster integration.
