SUI is a high-performance Layer-1 blockchain that launched publicly in May 2023 with its native token of the same name. Built on the Rust-based Move programming language, SUI enables fast, instant transaction finality and horizontal scalability through parallel transaction processing—resulting in low fees and high throughput. The network operates on a delegated Proof-of-Stake (dPoS) consensus mechanism, allowing users to secure the network and earn rewards by staking their tokens.
One of the safest ways to store and stake SUI is by using a Ledger hardware wallet, a trusted cold storage solution that protects your digital assets from online threats like hacking and fraud. By combining the security of Ledger with the earning potential of SUI staking, you can safeguard your holdings while generating passive income.
This comprehensive guide walks you through setting up your Ledger device for SUI, securely storing your tokens, and staking them with ease.
Why Use Ledger to Hold and Stake SUI?
Before diving into the setup process, it’s important to understand why Ledger stands out:
- Offline Security: Your private keys never leave the device.
- Phishing Protection: Prevents unauthorized access even on compromised computers.
- User Control: You remain in full control of your assets at all times.
- Staking Integration: Supports direct staking via compatible wallets like the official Sui Wallet.
Using Ledger ensures your SUI tokens are protected while still being active in the network’s consensus mechanism.

Step-by-Step: Setting Up SUI on Ledger
Follow these clear steps to store and stake SUI safely using your Ledger device.
1. Prepare the Sui Wallet Browser Extension
The first step is installing the official Sui Wallet browser extension:
- Visit the Chrome Web Store and install the Sui Wallet extension.
- Open the extension and click "Get Started".
- Choose "Create a New Wallet" if you’re new, or "Import an Existing Wallet" if you already have one.
- Set a strong password and keep it secure. This password encrypts your local data but does not replace seed phrase recovery.
- During setup, you'll see a recovery phrase—do not save this. Since we're connecting to Ledger, we won’t use this software-generated seed. The hardware wallet will manage security.
- Click "Open Sui Wallet" to proceed.
- Ensure you're on Sui Mainnet by clicking the network selector (top right) and selecting "Sui Mainnet".
2. Configure Your Ledger Device
Now prepare your Ledger to work with SUI:
- Update your Ledger device to the latest firmware using Ledger Live.
- Install or update Ledger Live on your computer and connect your device.
- Unlock your Ledger by entering your PIN.
In Ledger Live, go to the App Catalog, search for "SUI", and click Install.
- If SUI isn’t visible, double-check that your firmware is updated.
- After installation, close Ledger Live to prevent connection conflicts.
3. Connect Ledger to Sui Wallet
Now link your hardware wallet to the browser extension:
- Return to the Sui Wallet browser extension and unlock it with your password.
- Click the Settings (⚙️) icon → Accounts → Connect Ledger Wallet.
- Unlock your Ledger if prompted, then click Next.
- A popup appears asking you to select your Ledger device—click Connect.
- Choose the account you'd like to use from the list shown, then click Unlock.
✅ You’ve now successfully connected your Ledger-generated address to the Sui Wallet.
Transfer SUI tokens to this address for secure storage or staking.
- For beginners, send a small test amount first to confirm receipt before moving larger sums.
How to Stake SUI Using Ledger
Once connected, you can begin staking directly through the Sui Wallet interface.
Important: Enable Blind Signing on Ledger
SUI uses advanced cryptographic features that require Blind Signing to be enabled on your Ledger:
- Open the SUI app on your Ledger device.
- Use the right button to navigate to Settings.
- Press both buttons simultaneously to enter settings.
- Navigate to Blind Signing and press both buttons again.
- Confirm that the status changes from "Blind Signing Disabled" to "Blind Signing Enabled".
- Press the right button to go back, then confirm the change with both buttons.
🔒 Blind Signing allows signing transactions whose details aren't fully readable on-device. It's required for SUI but should only be used with trusted applications like the official Sui Wallet.
Start Staking Your SUI
- In the Sui Wallet, ensure you're using your Ledger-connected account.
- Click "Stake & Earn SUI".
Browse the list of available validators.
- Research validator performance, uptime, commission rates, and reputation.
- Consider spreading stakes across multiple validators to support decentralization.
- Select a validator and click "Select Amount".
Enter the amount of SUI you want to stake (minimum: 1 SUI).
- Note: A small gas fee applies—ensure you have extra SUI beyond the stake amount.
- Click "Stake Now".
If Blind Signing is disabled, your Ledger will show a warning. Enable it as instructed above and retry.
When prompted:
- Review transaction details on your Ledger screen using the right button.
- When "Confirm" appears, press both buttons to approve.
🎉 Congratulations! You're now staking SUI securely via your Ledger device.
Rewards will begin accruing in the next network epoch (approximately every 24 hours). You can track earnings directly in the Sui Wallet.

Monitor and Manage Your Stake
After staking:
- Check your staking status regularly in the Sui Wallet > Stake tab.
- View detailed transaction history and validator info using the Sui Explorer.
- Unstake at any time (note: there’s a ~7-day unlocking period before funds become withdrawable).
You can also re-stake rewards automatically or delegate to different validators as needed.
Key Tips for Safe and Effective SUI Staking
- Always verify URLs and download apps only from official sources.
- Never share your Ledger recovery phrase or allow others physical access to your device.
- Keep firmware and apps updated for security patches.
- Diversify validator choices to reduce risk and promote network health.
- Remember: staking involves risks such as slashing (penalties for validator misbehavior), though rare in well-run networks like SUI.
Frequently Asked Questions (FAQ)
Q: Is it safe to stake SUI on Ledger?
Yes. Staking through Ledger combines cold storage security with active participation in the network. As long as you follow setup instructions—especially enabling Blind Signing—you maintain full control without exposing private keys.
Q: What is Blind Signing, and why is it needed?
Blind Signing allows your Ledger to sign complex transactions (like those on SUI or Solana) that can't be fully decoded on-device. While powerful, it should only be enabled for trusted platforms like official wallets.
Q: How often are staking rewards distributed?
SUI staking rewards are distributed at the start of each new epoch, which occurs roughly every 24 hours. Rewards accrue automatically once your stake is active.
Q: Can I unstake my SUI anytime?
Yes, but unstaked tokens take about 7 days to become liquid again. This delay helps maintain network stability.
Q: Do I need internet-connected devices when staking?
Only during initial setup and transaction signing. Your private keys remain offline on the Ledger, so long as you disconnect after use, your assets stay protected.
Q: Are there fees for staking or unstaking?
There is a minimal gas fee for staking transactions (paid in SUI). Unstaking also requires a small gas cost when claiming funds after the cooldown period.
Final Thoughts
Storing and staking SUI on a Ledger hardware wallet offers an optimal balance between security and yield generation. With its cutting-edge architecture and growing ecosystem, SUI presents compelling opportunities for long-term holders who want to actively participate in network validation.
