Get started with a reliable Sui RPC endpoint to use the tools below.
JSON-RPC API Interact with your Sui node using the Sui JSON-RPC API .
Use your Chainstack Sui RPC endpoint to make API calls. Example to get the latest checkpoint:
curl --request POST \ --url YOUR_CHAINSTACK_ENDPOINT \ --header 'Content-Type: application/json' \ --data '{ "jsonrpc": "2.0", "id": 1, "method": "sui_getLatestCheckpointSequenceNumber", "params": [] }'
gRPC API Sui nodes on Chainstack support gRPC for high-performance access. gRPC uses HTTP/2 and Protocol Buffers for efficient binary serialization, making it ideal for streaming data and high-throughput applications.
Your Sui gRPC endpoint is available at:
sui-mainnet.core.chainstack.com:443 Authentication gRPC endpoints use x-token authentication. Pass your token in the request metadata:
x-token — your authentication token from the Chainstack console
Usage examples grpcurl -H "x-token: YOUR_X_TOKEN" \ sui-mainnet.core.chainstack.com:443 \ list
Find your gRPC endpoint and x-token in the Chainstack console under your Sui node’s Access and credentials section.
Sui TypeScript SDK The Sui TypeScript SDK is the official SDK for building Sui applications.
Installation npm install @mysten/sui.js Basic usage Connection
Query Objects
Send Transaction
import { SuiClient , getFullnodeUrl } from '@mysten/sui.js/client' ; // Connect to your Chainstack node const client = new SuiClient ({ url: 'YOUR_CHAINSTACK_ENDPOINT' }); // Get latest checkpoint const checkpoint = await client . getLatestCheckpointSequenceNumber (); console . log ( 'Latest checkpoint:' , checkpoint );
Sui Rust SDK The Sui Rust SDK provides comprehensive Rust bindings for Sui.
Installation Add to your Cargo.toml:
sui-sdk = { git = "https://github.com/mystenlabs/sui" , package = "sui-sdk" } tokio = { version = "1.2" , features = [ "full" ] } anyhow = "1.0" Basic usage use sui_sdk :: SuiClientBuilder ; #[tokio :: main] async fn main () -> Result <(), Box < dyn std :: error :: Error >> { let sui = SuiClientBuilder :: default () . build ( "YOUR_CHAINSTACK_ENDPOINT" ) . await ? ; let checkpoint = sui . read_api () . get_latest_checkpoint_sequence_number () . await ? ; println! ( "Latest checkpoint: {}" , checkpoint ); Ok (()) } Python SDK (pysui) pysui is a community-maintained Python SDK for Sui.Installation Basic usage from pysui import SuiConfig, SyncClient # Configure client with your Chainstack endpoint config = SuiConfig.custom_config( rpc_url = "YOUR_CHAINSTACK_ENDPOINT" ) client = SyncClient(config) # Get latest checkpoint checkpoint = client.get_latest_checkpoint_sequence_number() print ( f "Latest checkpoint: { checkpoint.result_data } " ) Go SDK The Sui Go SDK provides Go language bindings for Sui.
Installation go get github.com/block-vision/sui-go-sdk Basic usage package main import ( " context " " fmt " " github.com/block-vision/sui-go-sdk/sui " ) func main () { client := sui . NewSuiClient ( "YOUR_CHAINSTACK_ENDPOINT" ) ctx := context . Background () checkpoint , err := client . SuiGetLatestCheckpointSequenceNumber ( ctx ) if err != nil { panic ( err ) } fmt . Printf ( "Latest checkpoint: %s \n " , checkpoint ) }
