Sui RPC Endpoint

Fast, flat-rate Sui RPC node provider — free tier, no KYC, HTTP & WebSocket.

Sui is a high-performance Layer 1 from Mysten Labs built around an object-centric data model and the Move programming language. Independent transactions execute in parallel rather than through a single global queue, giving Sui high throughput and sub-second finality for simple transfers.

About Sui

Sui launched mainnet in May 2023. It uses a delegated proof-of-stake validator set and a consensus stack (Mysticeti) tuned for low latency. Its defining feature is the object model: assets are first-class objects with owners, so transactions touching disjoint objects don't contend and can be processed concurrently — single-owner transfers can even bypass full consensus.

Smart contracts are written in Sui Move, a resource-oriented language designed to make assets safe by construction. The combination of parallel execution and the object model targets consumer-scale applications: gaming, high-frequency DeFi, and on-chain assets that need cheap, fast updates.

Common Use Cases on Sui

On-chain gaming and high-frequency consumer apps
DeFi requiring low-latency settlement
NFTs and dynamic on-chain assets
Parallel, contention-free asset transfers
Apps using zkLogin for Web2-style onboarding

Sui Ecosystem

Notable Sui projects include Cetus and Turbos (DEXes), Scallop and NAVI (lending), Suilend, and DeepBook (a native order book), alongside a sizable gaming and NFT ecosystem. Mysten Labs maintains the core protocol and tooling.

Frequently Asked Questions: Sui

Does Sui have a chain ID?

Sui is non-EVM and doesn't use EVM chain IDs. It distinguishes networks by chain identifier (mainnet, testnet, devnet) and uses its own JSON-RPC method set.

What RPC methods does Sui use?

Sui exposes its own JSON-RPC API (sui_getObject, sui_getTransactionBlock, suix_* query methods, plus WebSocket subscriptions). It is not EVM-compatible, so ethers/web3.js don't apply — use the Sui TypeScript SDK.

Why is Sui fast?

Sui's object model lets independent transactions execute in parallel instead of through one global queue, and simple owned-object transfers can finalize without full consensus — together giving high throughput and sub-second finality.
