trezor-wallet's Issues

Not all accounts displayed

When connected to my Trezor T, only the first account is displayed although there are 4 (and 3 of them with non-zero balance).

Passphrase not working properly

We have encountered an issue while trying to use Trezor with passphrase protection. The wallet was generated correctly with a short passphrase. However, when we used a long passphrase that included spaces, the generated wallet was a completely new and empty wallet.

The generated wallet was different from the one generated using an empty passphrase.

CoinMarketCap Public API will be taken offline on December 4th, 2018

We currently use https://www.coingecko.com/api/docs/v3 in our web wallet.

Legacy addresses not displaying final balance correctly

I have just tested the wallet with my old Trezor One where I have zero balance at this time, however two legacy addresses that exist in this Trezor show non-zero ending balance, although the balance is really zero when connected to the official trezor wallet.
Incoming payment total is correct, however outgoing total shown on your wallet is lower than the actual one, so I suppose some outgoing transactions are either not counted or displayed.
The latest transactions seem to be shown correctly, as well as the first ones, since there is a lot of transactions, I wasn't able to browse through them all.
I can provide screenshots privately if needed.
