• The latest versions of Trezor Suite have implemented a security rule to disable its use with non-standard key paths. Therefore, the user must explicitly set Perform Safety Checks to PROMPT option in Trezor Suite in order to use the Trezor wallet in the PowPeg application.
• If is not enabled you will receive this error
• This video explains how to enable Perform Safety Checks to PROMPT on Trezor Suite Enabling Prompt for Key Path

• The PowPeg App uses Trezor Connect in a browser pop-up. Allow pop-ups for https://powpeg.rootstock.io (Mainnet) or https://powpeg.testnet.rootstock.io (Testnet). See Trezor will not connect (browser pop-up blocked).
• Confirm Perform Safety Checks is set to PROMPT in Trezor Suite. See FAQ 16 below.
• Unplug and replug your Trezor, unlock it with your PIN, and click Retry in the PowPeg App.

• Trezor Suite cannot show peg-out Bitcoin addresses at the custom derivation path. Use Electrum as described in Viewing a derived bitcoin address.
• If you do not use a BIP39 passphrase on Trezor, leave the passphrase fields empty in Electrum. Entering a value there opens a different wallet and the balance can look like zero.
• Electrum may prompt for a passphrase if Passphrase is enabled in Trezor Suite (Settings → Device → Passphrase). You can still leave the fields empty when you do not use a passphrase wallet.
• See Troubleshooting: peg-out completed but balance is zero and common errors.
