Sui JSON-RPC Migration Notice

The Sui Foundation has officially deprecated JSON-RPC. To ensure network performance and scalability, Tatum is transitioning the Sui infrastructure to a high-performance gRPC architecture.

Migration Path

To avoid service interruptions, please transition your applications to the new standard:

• Primary Action: Follow our Sui gRPC Migration Guide.
• Key Benefit: gRPC offers significantly lower latency and improved streaming capabilities compared to legacy JSON-RPC.

🚧

Attention

After the July 2026 End of Life date, JSON-RPC endpoints will be decommissioned and will no longer return data. We strongly recommend prioritizing this migration in your current development cycle.
