solayer-bridge

The Solayer Bridge (sBridge) is a canonical, SVM-native cross-chain bridge specifically designed to securely transfer assets and execute cross-chain transactions between Solana and Solayer environments. Unlike generic multichain bridges, sBridge is tightly aligned with the Solana Virtual Machine (SVM) execution semantics, enhancing interoperability, performance, and security.

Build Instructions

• Solana: Anchor build/anchor deploy
• Solayer: anchor build – –features solayer

You should not need to deploy anything on solayer as we do require a special build of solana binary to deploy. You can test on solana instead, or test on the deployed bridges

The deployed bridge handler is: 3V5J2eG4aSLU4Ld49YjY6JJLHVgA4mMNLZRVGM1vEQ6n on both solana and solayer chain
