Release-1.0.0 - Released 2026-06-08

• Latest PyPi Version

⚠️ Deletion Notice: Release 1.0.0 has removed the legacy JSON-RPC client and synchronous GraphQL client. If your code used either then use the Migration Guide on ReadTheDocs.

This is a significant release that redesigns pysui around the Unified Client Interface (UCI). It introduces breaking changes — see CHANGELOG for the full list.

Unified Client Interface (UCI)

The UCI provides a protocol-agnostic programming model: write application code once and run it transparently on either GraphQL or gRPC. The active transport is determined by configuration at runtime — no code changes required to switch.

The UCI is built on four pillars:

1. Thin Client Design — pysui clients carry no convenience methods such as get_coins or get_object. All data access goes through typed request objects dispatched via await client.execute(command=...), keeping the client surface small and transport-neutral.

2. Protocol-Agnostic Command Execution — Use await client.execute(command=...) with any SuiCommand subclass. The same code runs identically on both GraphQL and gRPC. Switching protocols requires only a configuration change.

3. Shared Transaction Infrastructure — PTBs with unified transaction builders and executor factories work across all protocols. Obtain a transaction builder via await client.transaction(**kwargs), and executors via await client.serial_executor(options=...) or await client.parallel_executor(options=...).

4. Protocol-Level Access — When you need capabilities beyond SuiCommand: use GraphQL QueryNodes via execute_query_node for custom queries, or gRPC Requests via execute_grpc_request for direct gRPC access.
