Connection issues

Information on how to connect Trezor with MyCrypto can be found in this article.

If you have trouble connecting your Trezor with MyCrypto, please make sure your configuration meets the following points:
 

  • Your Trezor is running the latest firmware.
  • You have Trezor Bridge installed on your computer. After the successful installation of Trezor Bridge, you should see "trezord" process running in your activity/system/task manager. If you cannot see the process running in the background, please try reinstalling it from this source. If Trezor Bridge is successfully installed, you will also be able to access Trezor Bridge Status page.
  • Use supported browsers only (Chrome and Firefox). Try both of them and try to use them in Incognito/Privacy mode as well. 
  • Clear your browser's cache and make sure it is up to date.
  • Not only using a VPN, but also certain advanced Firewall or Antivirus settings, browser extensions (AdBlock, Privacy Badger, etc.), may cause connectivity issues, therefore please try to disable them as well. 
  • On top of that, use only one application/website/browser tab with Trezor at a time. It is possible that they are clashing with each other. 
  • Download and use the MyCrypto Desktop App.


 

Different addresses in step "Select an Account"

If you can't see desired address with your funds after exporting public keys from Trezor to MyCrypto, it means you are accessing a different wallet. Either you have a different recovery seed stored in your Trezor or you are entering a different passphrase.

To access a wallet that includes the address you want to add to MyCrypto, you need to use the same combination of recovery seed and passphrase as you used when you generated this address for the first time.

You can find more information on issues with passphrase in this article

 

Unable to sign a transaction

If MyCrypto preventing you from spending your funds (signing a transaction), this actually might be caused when the (appropriate) private key is missing. These private keys for signing transactions are derived from the combination of the recovery seed stored on Trezor device and passphrase (if enabled and used). Hence, if a different recovery seed and/or a different passphrase is used then the private key differs and cannot be used. In such case, previously generated wallets/accounts in third-party apps would become watch-only wallets without the possibility of spending the funds. 

To be able to successfully sign a transaction, you need to use the right combination of recovery seed and passphrase for the address from which the transaction is being made.
