We built Radar Relay because we believe in wallet to wallet trading. In addition to supporting MetaMask, we are thrilled to now support Ledger hardware wallets. Ledger is the most secure, trusted, and widely available hardware wallet on the market.

How to

Connect your Ledger

  • Connect your Ledger hardware wallet to your computer.
  • Enter your PIN to unlock your device.
  • Open the Ethereum Application on your Ledger.

Get set up

  • On the Radar Relay app, open the wallet drawer.
  • Select the Ledger radio button at the top of the drawer.
  • Follow the instructions that appear.

Use your Ledger

  • Once you’re set up, use the dropdown to set which Ledger address you want to use.
  • You should now see your token balances in the wallet drawer.
  • Transactions will now be completed or canceled on your Ledger.

Completing a transaction

We will use enabling a token as an example.

  • Click the enable toggle next to a token.
  • Choose the gas price you would like to use with the slider that appears and click the create transaction button. If you aren’t sure what gas price to use visit https://ethgasstation.info/ and look at the recommended gas prices.
  • Confirm the transaction on your ledger.

Other Updates

  • Dai pairs — Added a new marketplace selection that allows you to choose between token pair denominations. Currently available are WETH and DAI.
