How to Connect a Hardware Wallet to Rabby Wallet

Supported Hardware Wallet Models

1. Rabby Wallet officially supports Ledger Nano S, Ledger Nano X, and Trezor Model T devices.

2. Each model requires firmware version 2.0 or higher for Ethereum app compatibility.

3. Ledger devices must have the Ethereum application installed and opened before initiating connection.

4. Trezor Model T requires WebUSB support enabled in browser settings and Trezor Suite running in background.

5. Samsung Blockchain Keystore is not currently recognized by Rabby Wallet due to proprietary communication protocols.

Browser Environment Requirements

1. Chrome version 110 or newer is mandatory; Chromium-based browsers like Edge may function but are unsupported.

2. WebUSB API must be enabled manually via chrome://flags/#enable-webusb on desktop installations.

3. Mobile browsers including Chrome for Android and Safari for iOS do not support hardware wallet connections to Rabby.

4. Browser extensions that modify page behavior—such as ad blockers or privacy tools—must be disabled during pairing.

5. Incognito mode prevents persistent device recognition; users must allow site permissions for USB devices each session.

Step-by-Step Connection Workflow

1. Launch Rabby Wallet extension and navigate to the Accounts tab.

2. Click Add Account → Hardware Wallet and select the appropriate device type.

3. Connect the hardware wallet via USB cable and unlock it with PIN.

4. Confirm the Ethereum app is open on Ledger or the dashboard is active on Trezor.

5. Rabby will detect the device and display a list of available derivation paths; choose one and click Import.

Common Authentication Failures

1. Device not recognized after multiple attempts usually indicates outdated firmware or missing Ethereum app.

2. “Timeout while waiting for device” error occurs when the hardware wallet screen remains idle past 30 seconds.

3. “Invalid signature” appears if the user rejects a transaction prompt on-device before signing completes.

4. “Connection refused” may result from another browser tab simultaneously accessing the same hardware wallet.

5. Ledger Nano S Plus users report inconsistent detection unless the device is rebooted prior to connection.

Frequently Asked Questions

Q: Can I connect more than one hardware wallet to Rabby at the same time?Only one hardware wallet can be actively connected per Rabby session. Switching requires manual disconnection and reinitialization.

Q: Why does Rabby show “No compatible device found” even though my Ledger is plugged in and unlocked?This typically stems from the Ethereum app not being launched on the Ledger or WebUSB being disabled in Chrome flags.

Q: Is it safe to use Rabby Wallet with a hardware wallet on a public computer?No. Public computers pose significant risk of keylogging, device spoofing, or malicious browser extensions intercepting device handshake signals.

Q: Does Rabby store any private key material when importing accounts from hardware wallets?Rabby never stores or caches private keys. All signing operations occur exclusively within the hardware device’s secure element.
