# Sui TypeScript SDK Quick Start

TypeScript SDK for building on the Sui blockchain



The Sui TypeScript SDK is a modular library of tools for interacting with the Sui blockchain. Use it
to send queries to RPC nodes, build and sign transactions, and interact with a Sui or local network.

## Installation

```sh npm2yarn
npm i @mysten/sui
```

## Network locations

The following table lists the locations for Sui networks.

| Network | Full node                             | faucet                                   |
| ------- | ------------------------------------- | ---------------------------------------- |
| local   | `http://127.0.0.1:9000` (default)     | `http://127.0.0.1:9123/v2/gas` (default) |
| Devnet  | `https://fullnode.devnet.sui.io:443`  | `https://faucet.devnet.sui.io/v2/gas`    |
| Testnet | `https://fullnode.testnet.sui.io:443` | `https://faucet.testnet.sui.io/v2/gas`   |
| Mainnet | `https://fullnode.mainnet.sui.io:443` | `null`                                   |

<Callout type="warn">
  Use dedicated nodes/shared services rather than public endpoints for production apps. The public
  endpoints maintained by Mysten Labs (`fullnode.<NETWORK>.sui.io:443`) are rate-limited, and support
  only 100 requests per 30 seconds or so. Do not use public endpoints in production applications with
  high traffic volume.

  You can either run your own Full nodes, or outsource this to a professional infrastructure provider
  (preferred for apps that have high traffic). You can find a list of reliable RPC endpoint providers
  for Sui on the [Sui Dev Portal](https://sui.io/developers#dev-tools) using the **Node Service** tab.
