The new Solana Attestation Service (SAS) lets apps verify KYC, region, accreditation, or sybil-resistance using wallet-linked credentials — no data exposure, no repeated onboarding. Think of it as OAuth for crypto identity. It’s already live on mainnet, with early adopters like Civic, Trusta, Sumsub, and Solid using it to issue reusable attestations for compliance, access control, and reputation. Why it matters: as Web3 matures, every serious app will need portable, verifiable identity.
This makes Solana the first chain with a composable identity layer that works across DeFi, gaming, DePIN, and tokenized assets.
