Ledger interaction

[vncoelho]

Hi O3 Labs team,

First of all, I would like to congratulate all of you for the great work and quality of products you are delivering to the Ecosystem.

I believe that there is a minor thing to be done regarding Ledger interaction.
The BIPS that specify deterministic wallet generation recommends that we should have one account and then keep generating addresses.

I mean:
Someone creates an account:

• A1: Temporary
• A2: Savings
• A3: My Pizza Company

Each time you receive any funds in any of these account O3 wallet should give another address of each specific account to receive the next funds.
In this sense, the procedure is to check balance until you find an address of that account that has not yet received funds.
