MetaMask is the browser or mobile interface. Ledger signs every transaction on its own screen. This setup keeps private keys offline. Even if your computer has malware, funds cannot move without your physical approval. The trade-off is one extra confirmation per transaction. There are two main ways to connect. USB works on desktop browsers. Bluetooth works on mobile with compatible Ledger models. Both need the Ethereum app installed. When you use Onchain, the connection works the same way. Onchain is a web dApp on Ethereum Mainnet. You connect MetaMask, approve Permit2, a Uniswap contract, and sign an off-chain authorization. The Ledger still confirms the signature. The server wallet pays the gas, so you pay zero gas for signing. The "Connect Hardware Wallet" option in MetaMask is the starting point. It walks you through selecting Ledger and importing the Ethereum account. You can always disconnect the hardware wallet later without losing funds. Step-by-Step: How to Set Up a Ledger dApp Connection MetaMask Install the Ethereum app on your Ledger. Open Ledger Live, go to "My Ledger," search for "Ethereum," and install it. Update your Ledger firmware. In Ledger Live, check for OS updates and install any available version. Update MetaMask to the latest version. In the extension or mobile app, go to Settings > About and confirm you are current. Close Ledger Live. Ledger Live can block the connection between MetaMask and your device. Unlock your Ledger and open the Ethereum app. The screen should say "Application is ready." Open MetaMask and click your account dropdown. Select "Add account or hardware wallet." Choose "Add hardware wallet." Select Ledger from the list. This is the Connect Hardware Wallet step. Connect via USB or Bluetooth. On desktop, plug in the device and approve the browser prompt. On mobile, pair via Bluetooth. Select the account you want to import. Check the box next to the Ethereum account and click "Unlock." Your Ledger account now appears in MetaMask. Every signature still needs your device. After the account appears, test it with a small transaction. Send a tiny amount to yourself or sign a message. Confirm the details on your Ledger screen before approving. This verifies the connection works. For Onchain, visit onchaindiagnois.com after MetaMask shows your Ledger account. Connect MetaMask, approve Permit2, and sign the off-chain authorization on your Ledger. You pay zero gas for that signature. The server wallet pays the gas. Common Issues and How to Fix Them UNKNOWN_ERROR (0x650f): Close Ledger Live. In MetaMask, go to Settings > Advanced > Preferred Ledger Connection Type and select WebHID. Then retry. Device not detected: Make sure the Ethereum app is open on your Ledger and the device is unlocked. Try a different USB cable or port. Bluetooth pairing fails: Confirm Bluetooth is enabled on both your phone and your Ledger. Keep the device within a few feet. MetaMask shows no accounts: You may be on the wrong derivation path. When importing, switch between "Ledger Live" and "Legacy" to find your accounts. Firefox connection drops: Firefox no longer supports the U2F method MetaMask uses. Switch to a Chromium-based browser like Chrome or Brave. Linux permission error: Run sudo chmod a+rw /dev/hidraw* in a terminal, replacing the device number with the one shown in chrome://device-log/. If these fixes do not work, check the official Onchain page for current details. You can also ask in the Onchain in-app chat or Telegram group. How to Contact Onchain Support Safely Onchain does not offer phone support. Anyone calling you claiming to be Onchain support is a scammer.

If someone asks for any of these, they are trying to steal your funds. Close the chat and report the account. Check the official Onchain page for current details.
