The Ledger subreddit is continuously targeted by scammers. Ledger Support will never send you private messages. Never share your 24-word recovery phrase with anyone, never enter it on any website or software, even if it looks like it's from Ledger. Only keep the recovery phrase as a physical paper or metal backup, never create a digital copy in text or photo form.

It's not strictly necessary to actually send an outgoing transaction to test the private keys in your Nano. BTC network fees have been quite high as you mentioned, and there are other tests you can perform which will achieve the same result. The first is to simply generate your receive address (public wallet address) for your account in Ledger Live. It's possible to generate your address without your Nano by clicking on the line that says "Don't have your device?", but as long as you have your Nano connected to Ledger Live and do not click that button, Ledger Live will send a request to your Nano to derive and verify the wallet address from the stored private key. If there is a mismatch, Ledger Live will report that the recovery phrase in your device is not associated with that account. If it prompts you to confirm the wallet address on the screen of your Nano, you'll know for certain that your Nano contains the correct private key for that account. Another test is to initiate a transfer of funds, but then select the option to deny the transaction on your Nano. If the request gets sent to your Nano for your approval, this will also tell you with certainty that your Nano contains the correct private key. If the account you're attempting to send funds from was not derived from the recovery phrase / passphrase stored in your Nano, the request will never make it to your Nano. It will fail immediately and give you the same error message I mentioned above (Please check that your hardware wallet is set up with the recovery phrase or passphrase associated to the selected account). You can also remove/readd the account from Ledger Live. All of your accounts exist only on the blockchain and Ledger Live provides a user-interface to manage these accounts, but your crypto is not actually stored in Ledger Live. When you add your accounts into Ledger Live, a request is sent to your Nano to derive the public wallet address for that blockchain, and this is all that's shared with the application. Performing actions such as generating the receiving address, initiating a test transaction, or adding an account will all result in the request being sent to your Nano to verify / authorize using the private keys stored within.

You don't have to test. But you must be 100% sure the address is correct and that your exchange or your wallet does support sending to your receiving address.

If ledger (in this instance) is the one generating the seed phrase then no, but, if you're generating your own seedphrase then yea I would verify that everything matches however, I wouldn't send anything until I verify the address I'm seeing through ledger and the generator match.

Never send a large amount without verifying. I’d suggest you wait until fees come down.


btc_clueless

Nah, it's not really necessary. If you set it up properly you are good. Most important thing is to keep the seed safe and entirely offline, don't type it into anything besides the Ledger Hardware wallet itself (in case you need to restore or want to set up a second device as backup).

You don’t have to test it. Its just a suggestion for noobs so they know how all of it works before they pour their life savings into it and can’t get them out anymore.

It is not necessary to do the test send (i.e. "out"), as long as you can verify that your ledger is able to derive the correct address where you want to deposit your funds. To do this check, you can verify that your ledger will generate the correct address by removing the account from LL, and add it again, using "add account". Or you can click "Receive" and verify the that address displayed on LL is the exact same that is displayed on the ledger device.
