Solana Introduces New Identity Layer to Power Onchain Trust

Dubbed the Solana Attestation Service (SAS), the protocol is now live on the Solana mainnet and offers a new standard for proving identity in Web3 ecosystems.

Created in collaboration with the Solana Foundation and Solana Identity Group, SAS enables users to attach off-chain credentials—like KYC data, investor status, or jurisdictional information—to their wallets.

These credentials are cryptographically signed and reusable across apps, allowing for trusted interactions without exposing personal data on-chain.

At its core, SAS is designed to be permissionless and open. Any developer or identity provider can integrate it without relying on centralized gatekeepers.

By leveraging the SAS SDK, applications can quickly perform secure identity checks, making the service scalable for capital markets and compliant apps.

Solana’s goal is to provide a universal “trust layer” for the internet economy—enabling identity verification that’s as fast and seamless as Solana’s blockchain itself.
