How do I sign and send transactions using my Ledger device?

Connecting Your Ledger Device to Wallet Interfaces

1. Connect your Ledger device to your computer using the provided USB cable.

2. Power on the device and enter your PIN code to unlock it.
3. Open the Ledger Live application and ensure your firmware is up to date.
4. Install or open the relevant cryptocurrency app (e.g., Ethereum, Bitcoin) directly from Ledger Live.
5. Navigate to a compatible web wallet such as MetaMask, MyEtherWallet, or Rabby, ensuring you are on the official website.

Signing Transactions Securely Through Hardware Verification

1. Initiate a transaction within the connected wallet interface by specifying the recipient, amount, and gas fees.

2. When prompted, confirm that the wallet recognizes your Ledger device as the signing source.
3. Review all transaction details carefully on the web interface before approval.
4. Press the button on your Ledger device to verify the recipient address, amount, and network fees displayed on its screen.
5. Only approve the transaction if the information matches exactly what you intended—this prevents man-in-the-middle attacks.

Submitting Transactions to the Blockchain Network

1. Once signed, the transaction is sent back to the wallet interface with a digital signature from your Ledger.

2. The wallet broadcasts the signed transaction to the blockchain network via connected nodes.
3. Monitor the transaction status through block explorers like Etherscan or Blockchain.com.
4. Wait for network confirmation; this may take several seconds to minutes depending on congestion.
5. Never share your recovery phrase or approve transactions requesting private key access.

Managing Multiple Accounts and Tokens Safely

1. Use different apps on your Ledger for distinct cryptocurrencies to avoid confusion.

2. Label accounts clearly in your wallet interface to prevent sending funds to incorrect addresses.
3. For ERC-20 tokens, ensure the Ethereum app is open on your Ledger when approving transfers.
4. Double-check token contract addresses when adding custom tokens to avoid phishing scams.
5. Regularly update both Ledger Live and individual coin apps to benefit from security patches.
