The Necessity of the Sui Wallet
The Sui Wallet extension is the official bridge connecting your web browser to the Sui blockchain. It acts as your identity, signing tool, and secure storage for $SUI$ tokens and other assets. Unlike exchange wallets, the Sui Wallet is **non-custodial**, meaning you retain full control of your private keys and funds.
Whether you plan to engage in **Spot** swaps on a decentralized exchange, execute complex trades on a **Perpetuals** platform, or deposit funds into a **Lending** protocol, the Sui Wallet is the mandatory first step for every on-chain interaction.
Step-by-Step Installation & Security
Step 1: Locate the Official Extension
Navigate to the official Chrome or Firefox web store (links provided below). **Crucially**, verify the publisher is 'Sui Foundation' or 'Mysten Labs'. Never download from third-party sites to avoid phishing scams.
Step 2: Add to Browser and Pin It
Click **'Add to Chrome/Firefox'**. Once installed, click the puzzle piece icon in your toolbar and pin the Sui Wallet for easy access. Click the Sui icon to start the setup process.
Step 3: Create a New Wallet
Select **'Create a New Wallet'**. You will be prompted to create a strong, secure password. This password encrypts the wallet locally on your computer and is required every time you open the extension.
Step 4: Secure Your Recovery Phrase (Mnemonic)
The wallet will display a **12- or 24-word recovery phrase**. This is the master key to your funds. Write it down **physically** (do not screenshot or save digitally). Store it in a safe, offline location. If you lose this, your crypto is lost forever.
Step 5: Confirm and Fund
Confirm the recovery phrase and finish the setup. You will now see your wallet address. To begin interacting with DeFi apps (Lending, Swaps, etc.), you must send $SUI$ tokens to this address to pay for gas fees and use as capital.
