Solana Foundation has launched Solana Attestation Service (SAS). This is a decentralized identity verification protocol designed to simplify compliance and enhance trust across the network.
Announced on 05/23, this tool allows off-chain data authentication applications, such as Know Your Customer (KYC) checks and user certification. It does this without directly processing users' sensitive information.
Solana Launches Identity Layer Amid Growing Global Crypto Interest
Solana Foundation stated that SAS introduces reusable cryptographically signed certificates that trusted parties can issue. After verification, users can seamlessly interact with multiple platforms without repeating registration or verification steps.
"SAS enables compliance, access control, programmable reputation and identity systems across the Solana ecosystem. This provides a better, easier experience for both end-users and developers," Solana Foundation said.
This design eliminates the need for developers to maintain identity systems, significantly reducing barriers to compliance feature integration.
According to the Foundation, SAS supports multiple use cases. These include DeFi compliance, access control in blockchain games, Sybil resistance in DAOs, and location-based verification for connected devices.
Developers can use this 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, an alliance of contributors including Civic, Solana.ID, Solid, Trusta Labs, and the Foundation itself. This group aims to develop privacy-preserving identity principles suitable for the Web3 era.
Meanwhile, the launch occurs against a backdrop of increasing interest from traditional finance in Solana's infrastructure. Nzube Ezido, national team lead of Solana Superteam NG, described SAS as a crucial part of the network's evolving financial system.
"This could be one of the most important principles launched in a very long time. As we rapidly accelerate on the capital market story, oracles holding RWA will need this to provide trust from on-chain to off-chain states," Ezido said.
In recent months, several traditional financial institutions have explored the network's potential for asset tokenization due to its speed, scalability, and low costs.
This is evidenced by R3—a blockchain infrastructure provider with over $10 billion in assets on the Corda platform—partnering with Solana. This collaboration aims to bring clients like HSBC and other major financial institutions to use the network's features.
Simultaneously, Kraken, a major US-based exchange, announced plans to use Solana's infrastructure to enable international trading of US-listed stocks.
Market observers note that these partnerships reflect Solana's growing role in connecting real-world finance and blockchain infrastructure.
