Received Nano Ledger S, Configuring it with Electrum

[jerry0]

Thanks for the response.


I meant when you click on receive on the ledger wallet bitcoin app.  It shows my btc receiving address.  I then copied and pasted it to electrum as im sending btc from electrum to nano ledger s.  I then look at the address on the nano ledger s itself to confirm it matches the address on the ledger wallet bitcoin address/electrum address.  Then when it does, i then right click to confirm.  Then i click send btc from electrum after copying my password into it.  I done this and it worked.  The issue i had was when i looked at the address and they were the same... i just sent the btc from my electrum wallet without right clicking confirm on the nano ledger s.  So at that point, i thought i messed up because i didn't confirm the address with a right click on the nano.  And also because the btc got deducted from my electrum but it didnt show up in my ledger wallet bitcoin until a while later on.   But the btc did show up a bit later.


I assume lot of ppl probably made a mistake like this?  Well for example it doesnt have to be me sending btc from electrum to nano ledger s.  Imagine i give my btc address for someone to send to.  Well i click receive on ledger wallet bitcoin and it shows address.  I then look at the address on the nano ledger s device and its the same address.  I then copy and paste it to the other person to send btc to my btc address.  They send it.  Then i noticed i did not right clicked confirm on the nano ledger s device.  I thought because i did not click confirm, that btc address i give someone else is not my btc address.  But im guessing lot of ppl probably forget to click confirm on their nano ledger s?  Is it even necessary to click confirm? 


Oh so you mean only when i send btc to someone else from my nano ledger s... i have to right click confirm on the nano ledger s right?  Such as someone give me their btc address... i copy and paste it in ledger wallet bitcoin.  Then i click send... then i look at the address on the nano ledger s screen and make sure thats the address... then right click it ... then it sends?  Thus if i do not right click it, its not possible to send btc to anyone?

When you click on 'receive' your devices generates an address.
To confirm the address has been really generated by your device, and there is no hacker targeting your device / replacing the address with one of his, you have to take a look at the screen of the nano s.
You don't even have to click anything on the ledger. You just have to compare the address on your desktop screen with the address on the nano s. If those are equal, everything is fine.
You only have to do this once per generated address. This is just to confirm the address is valid. This has nothing to do with transactions.
If you see the address from your desktop screen on your nano s when generating a new address with click on 'receive', you can be sure that this address really belongs to your nano s.

Everyone will be able to send you coins to this address at any time. Its just a security precaution against man-in-the-middle attacks (https://en.wikipedia.org/wiki/Man-in-the-middle_attack)

Yes.
The physical verification (nano s screen + clicking button) is mandatory to send coins or sign messages.
Thats the reason a hardware wallet is way more secure than a desktop/mobile/web wallet.

Also what percentage of people after buying the nano ledger s use it with electrum vs just the ledger wallet in chrome?

Does it really matter? Besides, I doubt anyone... even Ledger... could answer this question.

Could you use both or it has to be with one only?

Yes, you can use both...

Because im thinking maybe i shouldnt use the nano ledger s with electrum as it could get very complicated?  I read threads where ppl said they had issues because in nano ledger s they choose segwit as oppose to legacy but their electrum is 2fa and its not compatible with segwit so there is some issues there?  I do not want any issue like that at all.

Electrum 2FA has nothing to do with Ledger... You cannot use Ledger + Electrum 2FA... When you use Electrum+Ledger together, it creates a "watching only" wallet based on your Ledger's "xpub"... You can only spend from it if your Ledger is plugged in and unlocked.

I suspect the problems you were reading about were related to the fact that they were likely trying get either BCH or Bitcoin Gold or some other Bitcoin fork, but had coins in an Electrum 2FA wallet which makes it more difficult to get the fork coins.

But if you use the nano ledger s with the chrome store app, well you could view the balance anytime when you click on the app and the bitcoin app right?  But someone mentioned the negative thing about the nano ledger s is you cant view your btc balance or something by itself.  Can someone explain what they mean by that?

They mean if you use "Ledger Bitcoin Wallet" chrome app... it doesn't do anything until the Ledger device is connected and unlocked and a "coin" is chosen on the device...



As opposed to Electrum... it creates a "watching-only" wallet, so even if you don't have the device connected, you can still see all your balance, transaction history and addresses:



Note: Electrum now (as of version 3.1.0) has the option to encrypt the file on disk, in which case you need to have the device connected to open the wallet:
