Solana launches attestation service for on-chain identity verification

The Solana Foundation and Solana Identity Group have launched the Solana Attestation Service (SAS) on the #Solana mainnet. SAS is an open protocol that enables verifiable credentials to be linked to user wallets, allowing applications to verify off-chain information — such as KYC status, jurisdiction, or membership — without storing sensitive data on-chain. #SAS aims to streamline compliance, identity verification, and access control across the Solana ecosystem. It allows for reusable credentials, reducing the need for repeated verification steps across decentralized applications.
