[Urgent] Sui - Testnet - Upgrade to testnet-v1.80.1

Scheduled for Sep 22, 17:36 UTC  -  Sep 23, 00:00 UTC

Scheduled

We are upgrading our Sui Testnet infrastructure to testnet-v1.80.1 on 2026-09-22. This release introduces Protocol v137, which includes consensus-affecting changes such as refined gas charging for constants, network-wide acceptance of TransactionExpiration::Validity, stricter signing-time validation, and enhanced object-funds withdrawal checks. The release also expands gRPC and GraphQL capabilities.

Brief interruptions to RPC availability may occur on that date.

RPC Changes:
- SuiTransactionBlockEffects.shared_objects — Field derivation now includes implicitly read system objects (such as the accumulator root) once a consumer activates. Consumers treating this field as declared shared inputs must filter against transaction inputs.
- GetPackage, GetDatatype, GetFunction, ListPackageVersions (gRPC MovePackageService) — Now available on archival KV-RPC infrastructure (sui-kv-rpc), previously available only on full nodes.
- Historical subscription backfill (GraphQL) — Can now consume V1 effects from archival KV-RPC.
- QueryEndReason on empty natural interval queries (gRPC) — Queries ending on an empty natural interval now emit QueryEndReason::CheckpointBound with watermark.checkpoint = None instead of CursorBound.
- Transaction effects (gRPC v2 RPC) — V1 transaction effects now include their derived lamport version in v2 RPC responses.
