Following the launch of the Solayer mainnet, a re-staking standard within the Solana ecosystem has been introduced, namely the Endogenous Application Validation System (e-AVS) for re-staking (restaking). This innovation allows the Solana ecosystem to leverage its staking-weighted Quality of Service (QoS) advantage, creating a decentralized cloud marketplace. In this marketplace, users can stake SOL assets to obtain sSOL and delegate them to selected e-AVS. Through this mechanism, participants not only receive native staking rewards but also benefit from MEV (Miner Extractable Value) increases and additional earnings brought by the AVS. To further encourage developer participation and application innovation, Solayer also provides v1 development kits, allowing developers to interact directly with core functionalities. Additionally, the project has undergone a rigorous audit by Halborn Security, ensuring its security and reliability. Solayer plans to introduce more features in the future, such as protocol-internal fee modules and permissionless AVS management, to enhance the ecosystem. Since its launch on May 21, Solayer's total value locked (TVL) has exceeded $160 million. The project aims to address Solana network congestion issues through re-staking technology, providing reserved local network bandwidth and on-demand block space and throughput. It has already attracted several projects including Bonk, Alt Layer, HashKey Cloud, and Sonic to join as early adopters of endogenous AVS.
