Woher weiß ich, welche privaten Schlüssel von nicht-nativ unterstützten Münzen auf meinem Trezor gespeichert sind?

If it’s anything like it was back when ETH wasn’t natively supported, you’d have to view and sign transaction with your Trezor through another wallet service.

For ETH back then, an example would have been MyEtherWallet (MEW). You’d export your public keys to view balances and then sign privately directly from your Trezor.

I don’t know how ADA works, so I can’t speak to it specifically.

You should be going through other software for coins/tokens that aren’t on Trezor suite but are on the list of Trezor supported coins. For example, if you want to use your Trezor to hold ADA, you should download software like Daedalus for Cardano. Daedalus supports Trezor, make a Trezor wallet there and transfer the coins.

You will need some kind of middle man interface for each coin

The fact that you can view your ADA balance indicates your private keys are involved

**Trick question!** Trezor doesn’t work the way you think.

The only thing Trezor device actually _stores_ is the recovery seed. When you connect to Suite, or to Metamask, or Adalite, or Stellar Account Viewer, or anything, there is no new data added to the device. Trezor itself _doesn’t know_ if there’s any ADA or XLM or BTC or ETH or anything on it.

„Yeah? Then how can it „support coins“, where do the private keys come from?“ you ask.

The answer is, **all keys are computed on-demand from the seed.**

So if you connect Adalite, it says to Trezor: „Hey Trezor, show me ADA address at path m/1852’/1815’/0’/0/0.“ And Trezor does that, and shows you on screen, and then _immediately forgets that this happened_.

Then Adalite can say: „Hey Trezor, send transaction from ADA address at path m/1852’/1815’/0’/0/0, going to address ABCDXYZ, sending 33.9 ADA.“ And Trezor shows you the destination address, and the amount, and waits for you to click Confirm, and then generates a transaction that _would_ go from your ADA address, to the destination, _given that_ the address has enough funds.

_And then immediately forgets that this happened._

It’s the job of Adalite to figure out where the coins come from, what should be the input address, what amount to allow, etc., and ask Trezor to do the right thing. (If it does the wrong thing, it produces an invalid transaction and the Cardano blockchain will reject it.)

so to answer your question:

> **would I just be expected to remember which coins I had ownership of?**

Basically, yes.

Usually you just need to remember **which wallets** you used. Typically the wallet can do its own discovery of supported coins — similar to Suite, which will try to load up all coins that are enabled.

I’ve started keeping a spreadsheet with all this information, including bank accounts, crypto exchanges, brokerages for stocks, anything that I think I could forget. Optional information could include balances so you could recognize a discrepancy faster if you don’t notice it right away.

It depends on the chain itself; if all wallets within the given ecosystem use the same derivation paths, than any wallet will recover the same balance (like in case of Cardano)…

However the coins supported by Trezor right now, are planned to be added to Trezor Suit, so if you just wait, they will become visible there…

The Trezor device doesn’t know ANY of the coins you have, even the supported ones.

If you forgot all of your coins somehow, you would need to go through every app, including Suite, to determine. Suite wouldn’t know what you have at first either, so you would have to go into the Suite settings and enable every coin listed and then see what shows up. The only reason that Suite „knows“ currently what you have is because it remembers that you have enabled certain coins in the settings.

The same for other applications, you would just have to try them and see what (if anything) shows up.

Ok, so I want to say that I feel your pain. I use Trezor and Ledger. I started with Ledger and want to say that comparing t to an exchange, Ledger is like Coinbase. Entry level User friendly and easy to get around. Trezor, not so much. I really don’t want all the hidden wallets and such. Now, I use Trezor to hold only Ethereum.

No bashing or hate, but I still do not feel comfortable with the Trezor unit. By the way, their customer service is so slow, that the Ada you recently sent could be worth maybe $1.43 by the time they get back to you. Lol

Best luck…
