Solana Launches New Tool for DeFi KYC and User Verification
Solana Attestation Service (SAS) supports applications across DeFi, gaming, DAOs, and real-world asset (RWA) tokenization.
The Solana Foundation has launched the Solana Attestation Service (SAS). This is a decentralized identity verification protocol designed to simplify compliance and enhance trust across the network.
Announced on May 23, the tool allows applications to validate off-chain data, such as Know Your Customer (KYC) checks and user accreditation. It does this without directly handling sensitive user information.
Solana Launches Identity Layer Amid Rising Global Crypto Interest
Solana Foundation said SAS introduces cryptographically signed, reusable credentials that trusted parties can issue. Once verified, users can seamlessly interact with multiple platforms without repeating onboarding or verification steps.
“SAS enables compliance, access control, reputation systems, and programmable identity across the Solana ecosystem. It’s a better, easier experience for both end users and builders,” the Solana Foundation stated.
This design removes the need for developers to maintain identity backends, significantly lowering the barrier for integrating compliance features.
According to the Foundation, SAS supports a wide range of use cases. These include DeFi compliance, access control in blockchain games, Sybil resistance in DAOs, and location-based verification for connected devices.
Builders can use the tool to enforce region-based restrictions, establish user uniqueness, and create programmable reputation systems.
SAS marks the first release from the newly established Solana Identity Group, a coalition of contributors including Civic, Solana.ID, Solid, Trusta Labs, and the Foundation itself. The group aims to develop privacy-preserving identity primitives tailored for the Web3 era.
Meanwhile, the launch comes amid rising interest from traditional finance in Solana’s infrastructure. Nzube Ezido, country lead for Solana Superteam NG, described SAS as a critical piece of the network’s evolving financial stack.
“This might be one of the most important primitives launched in a very long time. As we quickly ramp up on the capital market narrative, oracles that keep RWA in sync will need this to offer trust for on-chain to off-chain state,” Ezido stated.
Over the past months, several traditional financial institutions have been exploring the network’s potential for asset tokenization due to its speed, scalability, and low fees.
This is evidenced by the fact that R3—a blockchain infrastructure provider with over $10 billion in assets on its Corda platform—was partnering with Solana. The collaboration aims to onboard clients like HSBC and other major financial institutions to leverage the network’s features.
At the same time, Kraken, a major US-based exchange, announced plans to use Solana’s infrastructure to enable international trading of US-listed stocks.
Market observers said these collaborations reflect Solana’s growing role in bridging real-world finance and blockchain infrastructure.

US CPI Exceeds Expectations Again, Waller's Warning Comes True! Wall Street Focuses on Whether December Rate Hike Will Be 25 or 50 Basis Points; "New Fed News Agency": Stop-and-Go Strategy Faces Test
The "New Federal Reserve Newsletter" pointed out that before the release of the CPI, Waller suggested the possibility of a 50-basis-point rate hike in December, and so far, no other Fed officials have publicly responded. In addition to a single 50-basis-point hike, the Fed may also choose to signal consecutive rate hikes in December and January. Wall Street generally believes that inflationary pressures remain stubborn, further strengthening the case for a rate hike in December, though a 50-basis-point increase is not a consensus. The market is concerned about whether the Fed will extend the tightening cycle.

After the release of the CPI, traders began to expect a lower likelihood of a 50 basis point rate hike in December; this year’s Federal Reserve voting member Logan stated that a faster pace of rate hikes may be needed this winter, with at least two more 25 basis point hikes required before pausing. Subsequently, the rise in U.S. Treasury yields continued to widen, with the 10-year yield climbing back above 5.0% and rising more than 10 basis points intraday; spot gold once fell over 3%, while spot silver at one point dropped more than 4%.
