Invalid channel error after transaction signing in v0.3.3 update #27

Closed ixje closed 1 month ago

ixje commented 5 months ago

Ledger released version v0.3.3 of the NEO app which breaks all wallets using a nano-s. The nano-s plus and Nano X do not seem to be affected. It was tested with these firmware versions

Nano X v2.2.3
Nano S v2.1.0
Nano S Plus v1.1.1

The error happens after transaction signing

The above is a screenshot of the neon-wallet app, but other wallets like O3 and NeoLine have the same problem.

Here's is a Python script to reproduce the error: gist

This is the same as the cli.py in this repo, but updated to work with the latest NEO Python SDK (and stripped slightly for brevity).

Steps to reproduce

install Python 3.11 or 3.12
pip install neo-mamba==2.6.0 ledgerblue
open the neo3 app, go to settings and change contract data to allowed (press both buttons at same time)
run python cli.py, review the transaction and choose accept. It will now throw the error

@ixje Hi, the issue has been fixed in the last 0.4.0 release (head of develop branch)
