description: Build Sui blockchain apps with @mysten/sui TypeScript SDK. Use when creating SuiClient, building/signing transactions (PTB), querying objects/events/balances, using faucet, integrating React/Next.js dApp-kit hooks (useCurrentAccount, useSignTransaction, useConnectWallet, useSuiClientQuery), wallet connection, Move calls, zkLogin OAuth, Passkey WebAuthn, Walrus storage, Seal secrets, Nautilus TEE, SuiNS names, DeepBook DEX, Mysticeti consensus, or SUI tokenomics/staking.

Sui TypeScript SDK

Build applications on the Sui blockchain using the official Mysten Labs TypeScript SDK.

Quick Start

npm i @mysten/sui
npm i @mysten/dapp-kit  # for React apps

Core Concepts

SuiClient Setup

import { getFullnodeUrl, SuiClient } from "@mysten/sui/client";

const client = new SuiClient({ url: getFullnodeUrl("devnet") });

Transaction Building (PTB)

import { Transaction } from "@mysten/sui/transactions";

const tx = new Transaction();
tx.moveCall({
  target: `${packageId}::module::function`,
  arguments: [tx.pure.string("arg1"), tx.object(objectId)],
});

const { bytes, signature } = await tx.sign({ client, signer: keypair });
const result = await client.executeTransactionBlock({
  transactionBlock: bytes,
  signature,
  options: { showEffects: true },
});

React dApp-Kit

import {
  ConnectButton,
  useCurrentAccount,
  useSignTransaction,
} from "@mysten/dapp-kit";

function App() {
  const account = useCurrentAccount();
  const { mutate: signTx } = useSignTransaction();
  return <ConnectButton />;
}

• Client Setup - SuiClient, networks, faucet, keypairs
• Transactions - PTB, moveCall, signing, gas, sponsorship
• Queries - Objects, coins, events, pagination
• dApp Kit - React hooks, wallet, providers

Framework Integration

• React Integration - Providers, query hooks, transactions
• Next.js Integration - App Router, SSR, API routes
• Best Practices - Error handling, caching, security

Authentication

• zkLogin - OAuth login (Google, Apple, Facebook)
• Passkey - WebAuthn biometric auth (Face ID, fingerprint)

Infrastructure

• Walrus - Decentralized blob storage
• Seal - Encrypted secrets with on-chain access control
• Nautilus - TEE off-chain computation
• SuiNS - Name service (alice.sui → 0x...)
• DeepBook - Orderbook DEX, limit/market orders

Protocol

• Mysticeti - DAG consensus protocol
• Tokenomics - SUI supply, staking, deflation
