Stellar developers meeting discussing CAP-84 and CAP-85. Protocol upgrades enable atomic updates across multiple Soroban contracts via executable references, solving the multi-contract fleet upgrade pattern without manual iteration.
Stellar's developer meeting explores CAP-84 and CAP-85, two protocol upgrades for Soroban smart contracts. CAP-85 introduces executable references, allowing multiple contract instances to share a single implementation and update atomically. Dmytro Kozhevin from SDF explains how this solves the multi-contract fleet upgrade pattern, enabling projects to manage implementations through a central manager contract. The solution maintains safety through typed reference entries while TTL extension semantics ensure persistence alongside contract code.
