                ### Interaction

<script src=""></script>


  <input id="account" type="number" min="0" value="0" onchange="connect()">

  <input id="pubkey" type="text" disabled="true" placeholder="Waiting for Ledger wallet...">


### Description

This pen makes use of `@cosmic-plus/ledger-wallet` to retrieve the public keys of Ledger wallet accounts.

### Keypoints

* `ledgerWallet` can connect to one account at once.
* It is not required to disconnect before changing the account number. `ledgerWallet.connect(account)` handles that in the background.
* Ledger browser libraries are only compatible with Google Chrome or browser based on it (Opera, Chromium, Brave,...).
* `@cosmic-plus/ledger-wallet` also supports Node.js environments.

### Challenges

- `[easy]` Edit that pen to Display the public keys of the 3 first accounts of the connected Ledger wallet.
- `[hard]` List all existing accounts after the BIP 44 definition − that is, until you find a series of 20 empty ones.

_Give it a try by forking that pen & editing the code!_
