We are upgrading our Sui Mainnet infrastructure to mainnet-v1.80.1 on 2026-09-30. This release introduces Protocol Version 137 with improvements to cryptographic verification, new gas charging semantics, and expanded transaction validation. Brief interruptions to RPC availability may occur on that date.
RPC Changes: SuiTransactionBlockEffects.shared_objects — The field is now derived from accessed consensus objects, which can include implicitly read system objects (such as the accumulator root). Consumers treating this field as declared shared inputs should filter against the transaction inputs to avoid processing unexpected system objects. Transaction expiration — TransactionExpiration::Validity is now accepted on all networks, allowing transactions to restrict which validators may propose them in consensus. MovePackageService (gRPC) — GetPackage, GetDatatype, GetFunction, and ListPackageVersions are now available on the Bigtable-backed archival gRPC service (sui-kv-rpc), previously only on fullnodes. Historical subscription backfill (GraphQL) — Can now consume V1 effects from archival KV-RPC for broader historical data access. QueryEndReason behavior (gRPC) — Terminal metadata on queries ending at an empty natural interval now emits QueryEndReason::CheckpointBound with watermark.checkpoint = None instead of CursorBoun.
