Hardware Ledger Support

[smaroudasunicorn]

• Be able to connect Ledger Hardware Wallet as a new account (currently Nano S supported by SDK).
• Sign messages and transactions with Hardware Ledger.

This is similar to airgap approach, UI have to be adjusted accordingly.

@smaroudasunicorn @CedrikNikita would you please check the suggested design and confirm if it's ok, do we miss anything, so I can update the user story with more detailed Acceptance criteria.

Design for Ledger support:

PROTOTYPE REC:

Ledger.Support.1.mp4

DESIGN:

1. Connect with USB connection:

2. Connect with Bluetooth:

3. Confirm transaction with Ledger device modal (+ Bitcoin and Ethereum accounts):

4. New place for imported account icons:

I am ok, not sure if we will support BT Ledger in this implementation package. @CedrikNikita ?

@smaroudasunicorn,

1. I synced about it with @CedrikNikita and it turns out that we are currently able of supporting only USB connect. So I'm providing an MVP version without BT support:

I'm suggesting to create separate user story in the backlog for USB/BT support with the existing design to be implemented at later stage if we have the time and resources.

2. In our sync call with @CedrikNikita we also discussed account discovery, derivation and technical limitations related so it turns out that we will be able to directly fetch and display only accounts with previous activity.
   Nikita also suggested to include a way of adding a specific account by entering its index number. May be you should check with him about this feature and do we need to include it. I'm a bit confused about the account discovery limitations according to currently implemented logic.

As far as I get the idea it should be something like this:

Importing Ledger account should not be available in mobile version

@smaroudasunicorn @CedrikNikita following our discussion about the technical limitations and current implementation of Confirm on Ledger modal I'm suggesting the following minor design update (2 alternative versions to chose from):

i believe v1 emphasizes more the message to the user
