Hi! Thanks for this PR - amazing work!

We (in Aurora Labs) have tested load_ledger_cli_owners function but unfortunately it only loads one owner at a time (with multiple ledgers/owners connected simultaneously).

Is it a known limitation? Is there a possible workaround?

Good point, I should test it, for now I was only testing one ledger.
I think that could be some limitations related with "ledger driver" and SO integration, but it is something interesting to test.

@vzctl with this new approach you can load more than one owner from ledger but you can only connect one ledger device.

Really nice, some small suggestions

Nice, using a exception file we prevent a posible circular dependency

Hola team! Small detail, the command available on the readme for installing ledger support is not the correct one, should be:

pip install '.[ledger]'

Cheers!

Hola team! Small detail, the command available on the readme for installing ledger support is not the correct one, should be:

pip install '.[ledger]'

Thanks, but that command is only for local development and using the last version. On the README we only have the command to use the last official release 😉

JagoFigueroa · 2023-10-31T10:15:37Z

Checking delegation! I see that in order to add or remove a delegate to a safe we need to be on tx-service mode and those commands look to be executed directly (something not possible to do from a ledger at this point).

tx-service > 0x6D04edC44F7C88faa670683036edC2F6FC10b86e > show_cli_owners
Account 0x454a478d2482C1d251F149424053d4485aDD3dC5 loaded
Not default sender set 
tx-service > 0x6D04edC44F7C88faa670683036edC2F6FC10b86e > add_delegate 0x357742b4799b3481dDbed8203CA06bFbe9Ca056E test 0x454
a478d2482C1d251F149424053d4485aDD3dC5
Account 0x454a478d2482C1d251F149424053d4485aDD3dC5 is not loaded
tx-service > 0x6D04edC44F7C88faa670683036edC2F6FC10b86e >

Here is me trying to do so from a ladger. My guess is that it fails as expected but maybe it is worth it to create a separate improvement to change that owner not loaded message as that is not the case for something referencing that it is not possible to add / remove delegates from a ledger?

Account 0x454a478d2482C1d251F149424053d4485aDD3dC5 is not loaded

(or something more generic for when we implement trezor too).

Cheers!

Other than that Ledger is working nicely for me on the CLI 😄

moisses89 · 2023-10-31T13:13:20Z

@JagoFigueroa thanks for your review :)
As the delegates issue that you mentioned is not something critical I created a separate task to implement it. #290
