How to use the Sui Wallet? (Sui ecosystem setup)

Installing the Sui Wallet Extension

1. Navigate to the official Sui Wallet website or the Chrome Web Store page for the Sui Wallet extension.

2. Click “Add to Chrome” and confirm the installation prompt to begin downloading the extension package.

3. Once installed, click the puzzle icon in the top-right corner of your browser and pin the Sui Wallet icon for quick access.

4. Launch the wallet by clicking its icon, then select “Create a new wallet” to initiate the setup flow.

5. Carefully write down and securely store the 12-word recovery phrase displayed on-screen — this is the sole method to restore wallet access if lost.

Connecting to the Sui Network

1. After wallet creation, the interface automatically connects to the Sui Mainnet by default.

2. To switch networks, click the network indicator (e.g., “Mainnet”) in the top-left corner and choose “Testnet” or “Devnet” from the dropdown list.

3. Each network maintains separate account balances and transaction history — assets on Testnet hold no monetary value.

4. Verify active connection status by checking the green dot next to the selected network name.

5. Ensure RPC endpoints are correctly configured; manual endpoint override is possible under advanced settings for custom node integration.

Receiving and Sending SUI Tokens

1. Click the “Receive” button to display your current Sui address as a string and QR code.

2. Share the address or scan the QR code with another wallet to receive SUI or compatible Move-based tokens.

3. To send funds, click “Send”, enter the recipient’s Sui address, specify the amount, and review gas fee estimates before submission.

4. Confirm the transaction using your wallet password or hardware wallet signature if integrated.

5. Monitor pending transactions in the “Activity” tab — confirmed transfers appear with block height and timestamp details.

Managing Objects and Smart Contracts

1. Access the “Objects” tab to view all owned on-chain objects including coins, NFTs, and smart contract instances.

2. Click any object to inspect its type, owner, version, and associated Move module.

3. Interact with deployed contracts by selecting “Interact” — this opens a dynamic interface generated from the contract’s Move ABI.

4. Input required arguments, select function calls, and sign execution requests using your private key stored locally.

5. All object mutations trigger a transaction requiring gas payment in SUI; failed calls still consume partial gas based on computation used.

Frequently Asked Questions

Q: Can I import an existing wallet using a Ledger device?A: Yes. Select “Import wallet” during setup, choose “Ledger”, ensure Ledger Live has the Sui app installed and opened, then follow on-screen signing prompts.

Q: Why does my balance show zero after switching from Testnet to Mainnet?A: Each network operates independently. Testnet SUI tokens are not transferable to Mainnet and hold no economic value outside testing environments.

Q: Is it safe to use the Sui Wallet extension on public computers?A: No. Never install or unlock the Sui Wallet extension on shared or untrusted devices — private keys remain accessible in browser storage until manually cleared.

Q: How do I verify the authenticity of a dApp requesting wallet connection?A: Always check the URL for HTTPS and domain legitimacy. Hover over the “Connect Wallet” button to preview the dApp’s origin. Never approve connections on phishing sites mimicking official interfaces.
