The @SuiNetwork has completely transitioned to gRPC. If your current infrastructure still relies on JSON-RPC routing, we encourage you to migrate to Ankr to experience high-performance gRPC that maintains low latency across any traffic volume. In addition, Ankr provides GraphQL for highly efficient queries, complete historical data through full archive access, and Agent RPC to seamlessly connect agents to Sui using Claude Code or Cursor. You can set up a free endpoint in just a few minutes with absolutely no credit card required. Please find the link below.
