Get a low-latency RPC endpoint to Sui

Create a high-performing geo-balanced Sui RPC node — keep your app always fast, always available. Deliver consistent performance worldwide with enterprise-grade reliability.

Create RPC endpoint

Reliable Sui Mainnet infrastructure

Chainstack makes sure you get access to robust and scalable infrastructure, ready for your Sui journey, in a matter of minutes.

We take away the burden of managing it so that you can instantly focus on building and exploring data on Sui RPC and API.

Create a node

GLOBAL NODES Start fast with Global Sui RPC Nodes

Global Sui RPC Nodes provide personal, geographically diverse, and protected API* endpoints you can immediately start using to interact with Sui Mainnet, starting at $0 per month.

Best throughput

Never be short on resources when you need them. Enjoy the highest throughput in the industry, regardless of traffic volumes. Need to handle a massive influx? Go for it.

No daily request limits

All our plans include class-leading monthly request volumes with no limits on the number or type of requests your DApp can make every day. Daily request limits? Who needs that?

Learn more

Global endpoint locations

Geo-load-balanced and distributed worldwide, Global Nodes automatically route requests to the nearest geo-located servers for the fastest service seamlessly.

Unbeatable pricing

No method-specific fees. To make your monthly infra spending predictable, every API call to your node is billed at a flat rate in Request Units, or RU irrespective of the type of request or the computational resources it requires.

Request Sui Dedicated RPC node

Request access to enterprise-grade Sui dedicated RPC services tailored for performance, reliability, and scale.

Notes for SUI API

When communicating with a Sui node, the client uses the Sui JSON-RPC API — not Ethereum JSON-RPC. The recommended library for TypeScript/JavaScript is @mysten/sui, and for Python use the pysui SDK.

Uses the Move programming language and an object-centric data model with parallel transaction execution for high throughput.

You can also access Sui directly through the Chainstack MCP server — query live on-chain data, deploy nodes, request testnet funds from the faucet, and search Chainstack docs from Claude, Cursor, Windsurf, ChatGPT, Codex, Pi, Gemini, or any MCP-compatible or SKILL-compatible AI agent.

Frequently Asked Questions

What is Sui?

Sui is a Move-based L1 from Mysten that uses Narwhal-Tusk DAG for parallel execution; its object model enables single-owner NFT transfers without global consensus.

How to get Sui RPC endpoint?

Sign up for a free Chainstack account and open your project dashboard. In the dashboard, choose Add node, select Sui, and provision either a dedicated node or an elastic cluster. After the node syncs, open Access & credentials and grab the RPC URL for immediate integration.

How to run a Sui node?

Chainstack’s Global Node puts Narwhal-Tusk DAG access one click away. A Dedicated Node grants predictable latency for object-based games. DIY means Move compiler builds, checkpoint syncs, and gas subsidy scripts.

What is Sui RPC API?

Sui’s full-node API is JSON-RPC over HTTP with methods like suix_getObject and suix_getCheckpoint. Transactions are BCS-encoded and submitted via sui_executeTransaction. Event subscriptions use a separate WebSocket channel.

How much does it cost to run a Sui RPC?

A Sui full node with Narwhal-Tusk DAG costs roughly US $120-200 / month; object storage can grow quickly. Frequent protocol upgrades mean higher engineering cost. Using Chainstack’s Sui RPC is generally the most cost-effective strategy.

Is Sui RPC free?

Sui devnet RPC is free, but checkpoint storms create hiccups. Chainstack keeps you humming with 3 million free Sui requests.

How to setup a Sui RPC?

Copy the Sui full-node URL from Chainstack Console. Place it in your wallet (Settings → Custom node) or in sui_client = SuiRpcClient(<URL>).
