全球Nodes

Connect to Sui through geo-balanced infrastructure that scales with request volume and routes traffic for reliable access across regions, with JSON-RPC and gRPC on every node and GraphQL on Mainnet.

Create Sui node →

专属Node

Run Sui workloads on isolated infrastructure across Chainstack locations, with single-tenant resources and greater control over node configuration.

申请node →

gRPC

Typed, binary API for lookups, transaction submission, and checkpoint streaming. Works from the browser through gRPC-Web.

gRPC docs →

GraphQL

Filtered, paginated reads: transactions by address, events by type, objects by owner. Same endpoint, 1 RU per request.

GraphQL docs →

JSON-RPC migration

Sui removes JSON-RPC from the full node code in mid-October 2026. Port call by call on the same endpoint, with no provider switch.

Migration guide →

Extended history

Tens of millions of checkpoints for point lookups and backfills. Read the exact window with GetServiceInfo.

Extended nodes →

One node. Three ways to call it.

Copy your endpoint and x-token from Access and credentials in the console, then run any of these.

Learn more about Sui

什么是Sui？

Sui is a Layer 1 blockchain from Mysten Labs built on the Move language and an object-centric data model. Assets are objects with their own IDs and versions, so transactions on independent objects run in parallel, and state is finalized in checkpoints. That design suits gaming, DeFi, and payments workloads.

How do I get a Sui RPC endpoint?

Create a free Chainstack account and sign in. Click Add node, select Sui, choose Mainnet or Testnet, and deploy a Global Node or Dedicated Node. When the node is running, open Access and credentials to copy your HTTPS endpoint and x-token; the gRPC endpoint is sui-mainnet.core.chainstack.com:443.

What is the difference between a Sui Global Node and a Dedicated Node?

A Global Node provides shared, auto-scaling RPC access through geo-balanced infrastructure, available on every plan. A Dedicated Node provides isolated, single-tenant infrastructure with predictable performance and greater control over node configuration. Global Nodes serve JSON-RPC, gRPC, and, on Mainnet, GraphQL.

Which Sui APIs does Chainstack support, and what happens to JSON-RPC?

Your Chainstack Sui node serves gRPC, JSON-RPC, and (on Mainnet Global Nodes) GraphQL on the same endpoint. Sui Foundation’s public endpoints no longer serve JSON-RPC, and Sui removes JSON-RPC from the full node code in mid-October 2026, so build new integrations on gRPC and GraphQL and port existing calls with the migration guide.

Is the Sui RPC API compatible with Ethereum?

No. Sui is not EVM-based and does not serve the eth_* interface. It uses its own object-centric API over gRPC, GraphQL, and JSON-RPC. Use the official @mysten/sui TypeScript SDK (version 2.16 or later for gRPC), pysui for Python, or the Rust and Go SDKs rather than an EVM library.

What is the native token on Sui?

SUI is the native token. It pays for gas and is used for staking. You can top up your Chainstack balance with 150+ cryptocurrencies.

Is the Sui RPC free?

Yes. The Developer plan is $0 and includes 3M request units per month at up to 25 requests per second. Every Sui request, whether gRPC, GraphQL, or JSON-RPC, costs 1 request unit, and paid plans start at $49/month with 20M request units.

Can I run my own Sui node?

Yes. Chainstack Self-Hosted supports Sui Mainnet and Testnet full nodes on your own infrastructure, with JSON-RPC and gRPC served on the same port. Learn more about Self-Hosted.

正常运行时间和性能保证是什么？

Chainstack Global Nodes and Dedicated Nodes are built for highly available, low-latency production access. Custom uptime SLAs are available on the Enterprise plan.

How can I monitor Sui node usage and performance?

在Chainstack 上使用node 分析功能，即可在一个地方跟踪请求量、响应时间以及node 的运行状况。

Notes for Sui API

Sui uses its own object-centric API, not the Ethereum eth_* interface. Your Chainstack Sui node serves gRPC (sui-mainnet.core.chainstack.com:443, with the x-token header), JSON-RPC over HTTPS, and, on Mainnet Global Nodes, GraphQL at YOUR_CHAINSTACK_ENDPOINT/graphql, all on the same node. Sui removes JSON-RPC from the full node code in mid-October 2026, so build new integrations on gRPC and GraphQL. gRPC streaming is documented for checkpoints (SubscribeCheckpoints), and GraphQL has no subscriptions. Recommended libraries are @mysten/sui 2.16 or later for TypeScript and pysui for Python. Every request, whether gRPC, GraphQL, or JSON-RPC, costs 1 request unit.

You can also access Sui through the Chainstack MCP server — query onchain 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.

Build on Sui with reliable RPC nodes

Reliable, scalable Sui RPC access over gRPC, GraphQL, and JSON-RPC on one endpoint, for DeFi, gaming, and payments workloads, fully managed by Chainstack.

One endpoint. Every Sui interface.
