How to connect my Trezor Model T to MyEtherWallet (MEW)?

Connecting Your Trezor Model T to MyEtherWallet

Integrating your Trezor Model T with MyEtherWallet (MEW) allows you to securely manage Ethereum and ERC-20 tokens without exposing your private keys. This hardware wallet provides an extra layer of protection by storing keys offline, while MEW offers a user-friendly interface for interacting with the Ethereum blockchain.

Prerequisites Before Setup

1. Ensure your Trezor Model T is initialized and updated to the latest firmware via the Trezor Suite.
2. Use a compatible browser such as Chrome, Firefox, or Brave with no conflicting crypto extensions active.
3. Visit the official MyEtherWallet website at https://www.myetherwallet.com to avoid phishing sites.
4. Have your Trezor Bridge software installed if using older operating systems; newer versions use WebUSB.
5. Keep your recovery seed physically secured and never input it into any online system.

Step-by-Step Connection Process

1. Navigate to https://www.myetherwallet.com and click on “Access My Wallet” located on the homepage.
2. Select the “Hardware Wallet” option from the list of access methods.
3. Choose “Trezor” from the available hardware devices—this triggers the connection prompt.
4. Connect your Trezor Model T using the USB cable and unlock it with your PIN code directly on the device.
5. Approve the connection request that appears on the Trezor screen by tapping the checkmark.
6. MEW will then display your wallet’s Ethereum address; confirm it matches the one shown on your Trezor device.
7. Once verified, click “Unlock” to gain full access to your wallet within MEW.

Performing Transactions Securely

1. After unlocking, you can view your ETH balance and any associated ERC-20 tokens by adding their contract addresses.
2. To send funds, click the “Send Transaction” button and enter the recipient address, amount, and gas fee preferences.
3. Review all transaction details carefully in MEW before confirming.
4. Your Trezor Model T will prompt you to verify the recipient address, amount, and network fees on its screen.
5. Physically confirm the transaction by pressing the confirmation button on your device—never proceed if details appear incorrect.
6. Once signed, the transaction is broadcasted through MEW to the Ethereum network and cannot be reversed.

Frequently Asked Questions

Can I use MyEtherWallet with other Trezor wallets?Yes, MyEtherWallet supports both Trezor Model T and Trezor One for Ethereum and compatible networks. The connection process remains consistent across both devices.

What should I do if MEW doesn’t detect my Trezor?Try refreshing the page, reconnecting the USB cable, or switching USB ports. Ensure no other wallet extensions like MetaMask are enabled, as they may interfere with device detection.

Is it safe to access my wallet on public computers?No, even though your private keys remain secure on the Trezor, public machines may have keyloggers or session hijacking tools. Always use trusted personal devices when accessing your wallet.

Why does the address on MEW differ from previous sessions?MyEtherWallet displays addresses based on the derivation path used. Trezor typically uses m/44'/60'/0'/0 by default for Ethereum. If multiple accounts exist, cycling through them may show different addresses—always verify on the device screen.
