Soda
Developer InfrastructureSoda gives Solana programs a native signing primitive for Bitcoin, Ethereum, Sui, Aptos, and every other chain. With one call, an Anchor program receives a real signature for any external network, and a Solana PDA literally owns the foreign-chain address. No wrapped tokens, no bridge vaults, no custodians, no humans clicking sign. Signing is split across operators bonded with restaked SOL, the same economic model EigenLayer uses to secure $10B+ on Ethereum.
