Your Blockchain wallet currently does not support ERC20 tokens. If you accidentally sent ERC20 tokens to your wallet, you will need to export your private key in order to access them.
- To export your ether private key, navigate to your Ether tab in the left hand side navigation.
- Click on Export Private Keys on the right side of the grey bar above your transaction history.
- Carefully read the warning message shown and click Continue.
- Enter your wallet password, then click Submit to view your private key.
As stated in the warning, you should never share your private key with anyone. Anyone with access to your private key has the ability to spend the funds associated with it.
Please note: your private key does not need to be exported to backup your ether funds. As long as you have your backup phrase written down and stored somewhere safe, they are already backed up.
