I've just verified this is indeed still an issue on latest Brave. Highlight me if you need any more information.

@bbondy Any progress on this internally?

@srirambv are you able to reproduce this issue?

Hmm, unlock account seems to work now!

Unfortunately sending between L2 accounts just gets stuck in a loop of verifying the signing address. The following approval appears in Brave wallet before the prompt on my Trezor T to verify the signing address:

Domain:

@abjugard By L2 account, do you mean that this transaction is happening on an L2, i.e. not Ethereum mainnet? If so, could you take a look at #23448 (comment) and let me know if that solves the issue.

[abjugard]

@nvonpentz It does not. Yes, I am trying to sign a transaction on loopring.io moving funds between two Loopring L2 wallets.
