[https://www.youtube.com/watch?v=dxSQHL5O8qk](https://www.youtube.com/watch?v=dxSQHL5O8qk) Guter Podcast. Jake Claver sagt etwas, das mich in der Diskussion über die jüngsten Ledger-Nachrichten wirklich beunruhigt. **Sieh dir 34:40 Minuten an** Er sagt, solange nur in die kalte Wallet und nicht aus der kalten Wallet gesendet wurde, sollte man sicher sein, da beide Schlüssel nicht offengelegt wurden. Auf der anderen Seite bedeutet das, dass, wenn Sie in UND aus Ihrer Wallet gesendet haben, zum Beispiel an eine Börse, bedeutet das nun, dass Ihre Wallet nicht mehr sicher ist? Zum Beispiel habe ich definitiv Krypto von meiner Cold Wallet zu Binance geschickt, um es zu verkaufen… aber ich habe auch Geld in meine Cold Wallet eingezahlt… bedeutet das nun, dass ich einen neuen Ledger kaufen muss, weil beide Schlüssel offengelegt wurden? Bitte klären Sie mich auf, das macht mir wirklich Sorgen.

To make a transaction *out* of a wallet, you need to interact with the private key in *some* fashion to sign the transaction. This is the only time the private key will be touched. If there is some vulnerability with the wallet, it’s possible for an exploit. This is the only thing I can imagine the speaker is referring to when discussing possible private key exposure.
In practice, the private key is *never* exposed to the outside world when signing a transaction. If any of the major software wallets or hardware wallets ever exposed the naked private keys, you’d see it explode over all social media channels as billions in funds would be lost overnight.
Your ledger wallet is not compromised when sending funds. There are millions of ledger users and hundreds of millions of output transactions that have happens on Ledger devices over the last decade, and no one is losing their funds or exposing their keys because they send funds to an exchange via a Ledger device.

With respect to your public and private keys, your private key allows you to derive a public key, create addresses to receive funds to in a safe manner – and store your assets safely, however this is a one-way process, such that your public key cannot derive your private key (in some reverse manner).
Your private key is ***never*** exposed in this situation that I’m mentioning – only the public key and address that you receive your funds to is exposed (this is regardless of if you’ve sent funds in and/or out of your wallet).
In either situation of sending or receiving funds, your private key is never exposed, not to worry.

Both keys? You talking about this new 3 piece „backup“ of you seed phrase that ledger is proposing? Transacting only deals with your individual crypto addresses, you never should expose your seed phrase to anyone or to any exchange.
With this new proposal and ledger’s software being closed source. I no longer trust them. I’ve since transfered all my coins/tokens out to another cold wallet.
If Microsoft is able to implement ADs and tracking through a simple update. What is to stop Ledger from implementing a way for them to take your seed phrase that is stored on your wallet, with a simple update without your knowledge?
Ledger is pulling a America right now. Make your users (citizens) dependent on them for safety and security. Ledger is now, essentially a hot wallet.

Try looking at it this way. You need an address to send crypto to, and you also need one to receive crypto.
These are not your keys.
They are temporary. They permit the transaction but do not have any other interaction with your wallet.
They get logged on the blockchain for transaction recording only.
You can use them again, if you wish, but with Bitcoin I generate new ones for every transaction.
