Emphasize coin in each screen

[tsusanka]

That'd be super cool. I was also thinking about something like a splash screen. When you start a workflow you'd start by confirming a coin's logo (maybe bitcoin default?).

Please keep the public conversation in English.

Also consider showing a network in cases where we support a number of them

https://github.com/trezor/trezor-common/tree/master/defs/coins now contains coin icons, so we can use that as well. Question is whether the coin icons are still recognizable if we downscale them to e.g. 16x16 pixels.

And what about altcoins icons that are not Bitcoin fork?

No worries, we won't leave them out. We add the icons if necessary

We're passing this one from one milestone to another. I don't think this makes sense to do before (or jointly with) #53.

[ZdenekSL]

We need to discuss with Peter how to prevent selecting the wrong coin with a similar shortcut (probably an icon).

Part of #53

Since we are currently limiting derivation paths to each coin this is less important than it used to be. The design and Suite should also help with this significantly. Therefore we have decided in the Product team we do not want to implement this at the moment.

That's a weird rationale.
The original issue is that the user can be confused/tricked into signing a transaction of the wrong funds on the wrong chain. So this very much still exists regardless of derivation paths. This is purely a UX issue, Suite can't help because it is on the host side, so "design" is the only place to resolve this, and I think that this issue is specifically about "keep this thing in mind for a redesign".

The original issue is that the user can be confused/tricked into signing a transaction of the wrong funds on the wrong chain.

Our rational was that the user can no longer be tricked because when they are on coin X they can't use paths for Y. But you raising a point when user would like to use X coin with X paths but is tricked to use Y coin with Y paths, do I understand it correctly?

Our rational was that in transaction signing Trezor displays the amount with the coin abbreviation so user should notice if they are signing ETH instead of BTC. But you are right that the difference between BTC and BTG for example is very small. And in message signing Trezor enforces the prefix so that should be fine as well. But the first point is something we should reconsider.

Exactly. Plus, this is even more relevant in case of tokens.

I think that this issue is specifically about "keep this thing in mind for a redesign".

We have discussed this with @matejzak with respect to the new redesign and he was against it. Mainly due to the maintenance reasons mentioning it was not that easy to make the icons nice and clean in Suite. He was strongly advocating for Trezor's design to be clear and simple. So I am suggesting to close this one unless we feel we really need it due to security concerns.

Please reopen if the rationale above does not seem sufficient.
