If you need to manage ERC20 tokens that are not supported by Ledger Live, you can use an external wallet like MyEtherWallet (MEW) while securely verifying and signing transactions with your Ledger device. Here’s a step-by-step guide to help you through the process:
Before You Start
Update Ledger Live:
Ensure Ledger Live is up-to-date via the notification banner or download the latest version from Ledger’s website.
Prepare Your Ledger Hardware Wallet:
Have your Ledger device ready.
Set Up MyEtherWallet (MEW):
Learn how to set up and use MyEtherWallet.
Entering Unsupported ERC20 Token Transaction Details
Add the Unsupported Token in MyEtherWallet:
Follow the MEW guide to add your unsupported ERC20 token. This allows you to manage it through MEW.
Enter Transaction Details:
Go to the Send Transaction section on MEW and input the transaction details. For detailed instructions, refer to MEW’s transaction guide.
Verifying Unsupported ERC20 Token Transactions with Your Ledger Wallet
Initiate Transaction:
Click on the Send Transaction button in MEW.
Verify Selector Parameter:
Your Ledger device should display the Verify Selector screen.
Press the right button to review the Selector parameter:
Selector: 0xA9059CBB (standard for token transfers)
Press the right button to navigate to Approve, then press both buttons to validate.
Verify Destination Address:
The device will show Verify Field 1.
Press the right button to review the Parameter: the destination address.
Verify the address, press the right button, then press both buttons to validate.
Verify Amount Sent:
The device will show Verify Field 2.
Press the right button to review the Parameter: the amount of token sent in hexadecimal.
Convert the Token Amount:
For example, hexadecimal amount: 1B9DE674DF070000.
Convert hexadecimal to decimal: 1B9DE674DF070000 = 1990000000000000000.
Token decimals can be found on Etherscan for the specific token. Example: 18 decimals.
Calculate actual token amount:
1990000000000000000 / (10^18) = 1.99.
Verify the amount and press the right button. Press both buttons to validate.
Review Final Transaction Details:
The device will display:
Amount: ETH 0 (Note: It’s an ERC20 token transaction, not ETH)
Address: The destination address
Max Fees: Maximum transaction fees
Press both buttons to Accept and send the transaction.
Completion:
You have successfully verified and signed the unsupported ERC20 token transaction.
