Do you know of an easy way to test this on testnet? E.g. is there some public "testnet merchant" running btcpayserver with payjoin enabled?

Can you reproduce this still? Would be nice if you could get the value of `n`. https://github.com/spesmilo/electrumx/blob/bf430353d635eeaf1d4fc0f107d6b947846e1d7f/electrumx/server/block_processor.py#L547 just change that line to ``` assert n == 0, n ```

@kevinbaker do you have any information about using approx what version or when the wallet was created, and approx which versions of Electrum had opened the wallet? It would also...

Ahhh ok I can reproduce. Old Electrum versions, pre-3.0, happily open future wallet files, corrupt them, and overwrite the version number with an old one. https://github.com/spesmilo/electrum/commit/348f66b8a5746e8ca789ab311b4bd5f6743705d6 Steps: - take wallet...

Maybe... I think the safest option would be to somehow make the upgraded wallet files unopenable to pre-3.0 versions.
