QA NOK

Tested in Exodus with same firmware version 2.4.3.
Signing/sending end in error.

Downgrading FW version to 2.4.2 does not solve the issue with Stellar Viewer, but it is now possible to sign a transaction with Exodus

Stellar viewer:
https://accountviewer.stellar.org/
Google Chrome Version 96.0.4664.93 (Official Build) (arm64)

Exodus:
21.12.3
macOS Big Sur Version 11.6 (20G165)

❌ 2.4.3 + Stellar viewer
❌ 2.4.3 + Exodus
❌ 2.4.2 + Stellar viewer
✅ 2.4.2 + Exodus

Successful transaction proceeded with Trezor Model T 2.4.2 + Exodus 21.12.3:

Trezor one is also the same, when I send it after signing with trezor-connect, I get the response "tx_bad_auth".

I only checked the firmware versions 1.10.3 and 1.10.4, but I got the same error. Too sudden, but is this caused by stellar network? Or trezor?

From what I can tell, the Account Viewer problem lies on Stellar side.

I am able to build and successfully send a virtually identical transaction with the same account on Testnet. However, Mainnet won't accept it. For now, I have no reason to believe that the signature is actually invalid.

Exodus appears to not send the asset field. We originally didn't require it, and assumed native if not specified. We now require it to be specified. This will need to be fixed on Exodus side. Do we have any way to contact them?

yeah but this isn't an Account Viewer problem either, looks more like their backend is hating on them or something.

With my Trezor and Stellarterm not communicating properly, my crypto is inaccessible and I’m losing thousands … what can be done about this? Is there any other way to access my funds??

Downgrading to Trezor Model T 2.4.2 does not solve the issue with StellarTerm. Assets held on SDEX remain entirely inaccessible via Model T on devices at any time upgraded to 2.4.3

It seems this will be fixed when we fix the issue in Trezor Connect - trezor/connect#970

[matejcik]

closing in favor of trezor/connect#970
wrt the Exodus issue, I've contacted them so hopefully they can fix this on their side.
