I am new to Ledger.

As a software program engineer, I would like to write down my very own app (for my very own private use) that’s kind of like a extra fundamental model of Ledger Dwell.

I need to present my balances alone personal dashboard on an internet site that I am constructing for myself.

I would like this web site to point out output like:

{
  BTC: 0.1,
  ETH: 1,
  NEAR: 20
}

the place every ticker reveals the whole (sum) of all tokens that my Ledger “holds”.

Since Bitcoin, Ethereum, and different blockchains are all public, I figured I would simply be capable to search for my wallets’ balances by way of the general public pockets addresses.

However now my understanding is that my Ledger’s public pockets addresses for every blockchain change after transactions.

So how can I accomplish my purpose?

Once more, I need a easy sum of the tokens as proven within the JSON above.

And I would like that sum to be retrievable periodically robotically with out me needing to log in on my Ledger.

Thanks!

P.S. I discovered Is it potential to make use of xpub tackle to observe stability from beforehand generated addresses? and How you can know stability in Ledger Nano S?

However once I go to Ledger Dwell > Accounts > Bitcoin > wrench icon > Superior and seize my “xpub” string and go browse it at https://www.blockchain.com/btc/xpub/xxxx, I see 20 pockets addresses (break up throughout 4 pages) with 0 transactions every. So it looks as if these are future wallets as a substitute of those that my Ledger has used up to now.
