SUI 1.81.1 > 1.82.3 API CHANGES

This section lists the API methods that changed in this release. Each link opens the method documentation with a note on what changed.

In Sui 1.82.3 the JSON-RPC service was removed from the Sui full node. All JSON-RPC methods (sui_*, suix_*, unsafe_*) are no longer available on the NOWNodes SUI endpoint. Use the SUI gRPC API (sui-grpc.nownodes.io) instead; see the official JSON-RPC migration guide.
