​
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": []
  }'

​
Sui TypeScript SDK

The Sui TypeScript SDK is the official SDK for building Sui applications.

​
Installation

npm install @mysten/sui.js

​
Basic usage

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

pip install pysui

​
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)
}
