How to Use Rabby Wallet with a Hardware Wallet

Rabby is an open-source, EVM-focused browser wallet built by the DeBank team. On its own it stores private keys in the browser — convenient, but exposed to malicious extensions, clipboard hijacks and phishing approvals. Pairing Rabby with a hardware wallet moves the private key onto a dedicated secure element: Rabby becomes a build-and-preview layer that prepares transactions and runs its Transaction Simulation (a pre-sign balance-change preview) and Security Engine risk checks, while the actual signature only happens after you physically confirm the details on the device screen.

That matters most for the thing Rabby is known for: it decodes and simulates a transaction before you sign, showing the expected balance changes and flagging risky approvals. Combined with on-device confirmation you get two independent checks — the software tells you what should happen, and the hardware shows you what you are actually signing. An attacker would need to compromise both. This is also why a hardware wallet is worth it even for a read-only DeFi power user: the most expensive mistakes are blind token approvals, and those are exactly what the device screen lets you catch.

Rabby supports a broad set of hardware wallets. Here is how each connects and what it covers:

Rabby is EVM-only. It manages Ethereum plus EVM Layer-2s and sidechains, and does not handle Bitcoin, Solana or Cosmos assets. For Solana + hardware wallet, see the Phantom guide linked below.

Shown for a Ledger over USB. QR devices such as Keystone and AirGap differ only at the pairing step — you scan a code instead of plugging in.

1. Install Rabby from rabby.io (which links to the Chrome Web Store), then pin it. Use a Chromium browser (Chrome, Brave, Edge) — WebHID pairing needs it.
2. Prepare the device: plug in the Ledger, enter your PIN, and open the Ethereum app on the device. Close Ledger Live if it is running, because only one app can hold the USB/HID connection.
3. In Rabby, choose Add an Address → Connect a Hardware Wallet → Ledger.
4. When the browser's WebHID dialog appears, select your Ledger and click Connect.
5. Choose the derivation path type. Rabby offers three: Ledger Live, BIP44 Standard and Legacy (MEW / MyCrypto). Pick the one your funds are on (see troubleshooting), tick the account(s) you want, and click Import.
6. Your device address now shows in Rabby with a hardware-wallet icon. You are paired, and no private key ever entered the browser.

Signing your first transaction

1. Start an action in a dApp (a swap, an approval, a send) and confirm it in the Rabby popup.
2. Read Rabby's pre-sign simulation: it shows the balance changes and flags risky approvals. If an approval requests an unlimited spend limit, consider editing it down.
3. Rabby forwards the transaction to the device. Verify the recipient address and amount on the Ledger screen itself — the device screen is the source of truth, not the browser.
4. Approve on the device. If Rabby shows "blind signing required", enable Blind signing in the Ledger Ethereum app settings and retry (older firmware called this setting "Contract data").

• Device not detected (WebHID): use a Chromium browser; fully close Ledger Live or Trezor Suite; unlock the device and open the Ethereum app before clicking Connect; try another cable or port (some cables are charge-only).
• Wrong or empty address after import: this is almost always the derivation path. Rabby's Ledger Live option is based on m/44'/60'/0'/0/0 (it varies the account segment per address), BIP44 Standard on m/44'/60'/0'/0 (it varies the final index), and Legacy (MEW / MyCrypto) on m/44'/60'/0'. If MetaMask showed your funds but Rabby does not, re-add the device and switch to the matching path type.
• "Blind signing must be enabled": open the Ledger Ethereum app → Settings → enable Blind signing (older firmware labelled this "Contract data"). Needed for contracts Rabby cannot fully decode.
• Firmware or app outdated: update device firmware and the Ethereum app in Ledger Live, then reconnect.
• Transaction stuck / nonce error: a previous pending transaction is blocking this one; clear or speed it up before signing a new one.
• Browser blocked HID permission: check the site-permissions icon in the address bar and allow HID for the extension.

If you already run the MetaMask + hardware wallet setup, the mechanics here will feel familiar — the device does the signing in both cases — but two things differ in practice. First, Rabby shows a balance-change preview and a risk assessment before the request reaches your device, so by the time you are confirming on the Ledger screen you have already seen what the transaction is expected to do. Second, Rabby auto-detects and switches networks based on the dApp you are on, which removes the manual "wrong network" mistakes that are common in MetaMask.

What does not change is the golden rule: the device screen is the final authority. Whatever Rabby predicts, you still verify the recipient and amount on the hardware wallet before approving. Many users keep both wallets pointed at the same hardware account and switch between them per task — see the MetaMask pillar guide linked below for that setup.
