Hey @msensys 👋🏼

Thanks again for another contribution!

We're trying to alleviate the CI failing now (#2574) - this will then allow us to unblock your PR's.

Thank you!

At the moment, I'm seeing what happened with CI.

This is just a flaky test, I suggest giving it a rerun when you see such an error :)

First pass, great work

Converting to draft until comments have been addressed.

@mvares We still need to update the wallet-transferring doc page and removed the duplicated section.

Both the Transferring Assets Between Accounts and Transferring Assets Between Wallets sections cover the same subject.

Since the Wallet classes extend from the Account class, we only need the Transferring Assets Between Accounts section as they use very similar examples.
