I am considering getting a Trezor. I have little interest in BTC at the moment (though multi-coin capability may be handy), so this would be based on the expectation that XMR compatible Trezor firmware will be fully functional going forward. Reasonable assumption?
Q

It already works

Just consider it beta until it's merged with the official Trezor firmware Wink

Yeah, I guess I mean is it a good bet that this will get official. I would be looking to use this for more than testing. Not really sure how bg a deal the viewkey transmission is.

Anyway, I prefer the idea of Trezor to paper wallets, so I hope it happens. Thanks to NoodleDoodle for doing the groundwork on this.

Q

I did some further testing. The viewkey is not really a big deal if you run a node yourself:
When you synced your wallet and disconnect your trezor, a file for each wallet is left on the PC. This is needed for when you reconnect your trezor.
But you can delete the file if you want. The only disadvantage is that you need to scan the whole blackchain again with your viewkey. I don't know if the viewkey is actually stored in this file, I should ask NoodleDoodle about it. But it at least seems to store which txo's are owned by your wallet.

What I'll probably will do is the following, have at least 3 wallets:
1) a passwordless spending wallet with a low amount. I'll keep the file on the PC. Easy to spend, easy to access, easy to prove the existence of the wallet.
2) a password protected "medium storage" wallet. If you don't want people to see you own a second wallet, you can encrypt and move the wallet-file to somewhere else and not keep it locally. When you need to access your medium storage, you get the file, decrypt it, and put it in the correct folder. You open the wallet, do your thing, and then encrypt and move the wallet file again. Harder to access, but still pretty fast process, difficult to prove the existence of the wallet.
3) a password protected wallet for long term storage. You delete the file to erase any prove that it exists. When you want to access it, you need to scan the blockchain again. Hard to aaccess, will take a while before you can spend it, impossible to prove the existence of the wallet.

You can keep for example 1% of your XMR in (1), 10% in (2) and 89% in (3)

I'll put all this in a manual once everything is considered "stable" alongside the basic "how to use trezor woth monero" Wink
