  The Metal wallet is linked to an Ethereum wallet under the hood. That's because Metal is an ERC-20 token that resides on the Ethereum blockchain. It carries smart contract information that identifies it as MTL. Therefore it needs a parent Ethereum wallet to cover for transaction fees.
  Step 2 asks "What kind of wallet do you want to create?" Select "Trezor".
  In Step 3, enter a name for the Ethereum wallet you want to create on your Trezor. It's good practice to give it a descriptive name to avoid uncertainty later.
  Connect your Trezor device to your computer via the USB connector. Once you inserted the pin code, start the Ethereum application on the Trezor, and click on the "Connect Trezor" button. You should see a popup.
  The drop-down menu will display multiple addresses; you're going to select one. If you already have an Ethereum wallet with funds on your Trezor that you want to link to Metal Vault, choose the address that contains the funds.
  You now successfully created an Ethereum wallet for your Trezor. The wallet is now accessible from the Metal Vault dashboard.
  Step 1 asks "Which currency would you like to use? Select "Metal".
  Step 2 asks "Which parent wallet do you want to assign? Select "The Ethereum wallet you just created".
  In Step 3, enter a name for the Metal wallet you want to create on your Trezor. It's good practice to give it a descriptive name to avoid uncertainty later.
  You now successfully created a Metal wallet for your Trezor. You can access this wallet from the Metal Vault dashboard whenever your Trezor device is connected.
