Sui Wallet: Your Gateway to the Sui Blockchain

Choose the right wallet

The Sui ecosystem has multiple wallet implementations: browser extensions, mobile wallets, and hardware integrations. Choose a wallet that is well maintained, open about its code (or audited), and recommended by the Sui documentation or community. Official and widely used wallets reduce the chance of running into fake or malicious apps. If you plan to hold significant funds, prioritize wallets supporting hardware keys or signing devices that keep the private keys offline.

Download & verify

Only download wallet software from the official source linked in the Sui docs or the project's verified website. For browser extensions, use the official browser store link (Chrome Web Store, Firefox Add-ons) referenced on the wallet’s official page. On mobile, prefer Google Play and Apple App Store links from the official site. Attackers often publish lookalike apps and extensions; always cross-check publisher names and install counts and confirm links from the official Sui site.

Verify source: sui.io and mystenlabs.com.

Seed phrase & backups

When a wallet is created it issues a recovery seed (mnemonic). This seed is the master key to your account. Write it down immediately, in the exact order displayed. Use offline, durable storage — paper in a safe or a metal seed backup product. Never photograph, email, or upload the seed to cloud storage. If an attacker obtains the seed, they control the funds. For extra safety, consider splitting the seed across multiple secure locations or use passphrase-protected seeds where the wallet supports it.

Backup guidance: keep one primary offline copy and one geographically separate spare for disaster recovery.

Hardware keys & cold signing

For meaningful balances, use hardware-backed signing. Hardware devices store private keys on a secure chip and only expose signed transactions. When supported, pair your Sui wallet interface with a hardware key and verify every transaction on the device display before approving. Hardware signing greatly reduces risk from malware or compromised hosts because the private key never leaves the device.

Hardware vendors: Ledger, Trezor and others — check Sui docs for supported devices.

Interacting with dApps & permission safety

dApps on Sui will ask for transaction signatures — sometimes for simple transfers, sometimes for smart-contract interactions that grant token allowances. Always read the permission request and understand what you are approving. Be cautious with blanket approvals (infinite allowances). If a dApp looks new or unvetted, perform a small test action first. Keep allowance amounts minimal and revoke approvals when they are no longer needed.

Security tip: prefer audited dApps and check project documentation and community audit reports before large interactions.

Swaps, fees & transaction confirmation

Some wallets integrate swapping or routing services. Before accepting a swap, preview the rate, fees, and slippage tolerance. Sui’s low-latency design means transactions confirm quickly; always verify the transaction details (recipient, amount, fee) before approving. Keep a record of txids for bookkeeping and potential disputes.

If you use third-party swap aggregators, check reputation and fees closely — and prefer on-chain explorers to confirm the completed transaction.

Sending & receiving — practical checklist

When receiving funds, copy the receive address from your wallet and provide it to the sender; double-check that the chain/network is correct. When sending, always confirm the destination address character-by-character, or better, scan a verified QR code. For large transfers, send a small test amount first. Be aware of clipboard-hijacking malware that replaces copied addresses on your device; pasting into a plain-text editor for verification adds one extra check.

Use the Sui explorer (e.g., explorer.sui.io) to check confirmations and details of transactions.

Phishing, scams & incident response

Phishing is the number-one vector for compromised wallets: fake websites, malicious extensions, and social engineering. Never enter your seed phrase into a website or share it with anyone. If you suspect you exposed your seed, move funds immediately to a new wallet created on a secure device and revoke any associated approvals where possible. Report phishing or impostor apps to Sui channels and the relevant app stores.
