Stellar network validators will vote on July 8 to approve Protocol 27, known as Zipper, which introduces native authentication delegation and improves security by fixing replay vulnerabilities in Soroban smart contracts. This upgrade simplifies account authorization, enabling features like social wallet recovery and streamlined multi-signature transactions, potentially lowering operational costs. Protocol 27 also sets the stage for Protocol 28, which will bring contract-based authentication to Stellar accounts. If approved, the update will first launch on the testnet before full deployment, requiring developers to update their tools for compatibility.
