Stellar Protocol 28 Upgrade Targets Soroban Smart Contract Enhancements

Stellar prepares Protocol 28 upgrade for Soroban, introducing atomic upgrades and AddressV2. Key milestones include testnet vote on August 27 and mainnet vote on September 16.

Woofun AI reports that Stellar is advancing Protocol 28, also known as Adapter, to enhance its Soroban smart contract platform. The upgrade introduces CAP-85 for atomic updates of shared executable code and CAP-86 for streamlined contract data migrations.

Additionally, Protocol 28 implements AddressV2, replacing the legacy address credential format to improve authentication infrastructure.

The governance schedule outlines a core stable release on August 13, with infrastructure and SDK updates expected between August 13 and 21. Validators will cast their testnet votes on August 27 at 17:00 UTC, followed by the mainnet vote on September 16 at 17:00 UTC. Activation remains contingent upon validator approval, requiring developers to update dependencies prior to these milestones.
