The open-source service lets approved issuers bind off-chain credentials, such as know-your-customer results, geographic eligibility, or accreditation status, to a user’s wallet address without exposing personal data on-chain.
Attestations live inside the wallet, travel across applications, and are verified with a software development kit call.
According to the announcement, the design removes repetitive onboarding checks and eliminates the need for each project to store sensitive identity records.
The Foundation said developers can deploy Solana Attestation Service to meet regulatory obligations, gate region-specific offerings, or build reputation systems that deter Sybil attacks.
Investors can hold “KYC passports” once and reuse them for future token sales, gaming studios can issue badges linked to provable player histories, and real-world asset platforms can confirm that buyers meet accreditation thresholds before releasing digitally wrapped securities.
Identity providers in Solana’s ecosystem have already integrated the new service. Additionally, infrastructure firms plan to ingest attestation data for risk scoring and transaction monitoring.
The Solana Identity Group developed the protocol. Group members said they would publish additional identity standards and invite other teams to contribute through open-source repositories.
Solana Attestation Service arrives as the Foundation and independent builders push the concept of internet capital markets.
Solana’s new attestation service is central to this new crypto sector. It lets decentralized applications confirm legal eligibility without re-creating legacy databases.
