Ledger Nano S related questions

[josephdd1]

Just a question: Does Ledger Nano S support all ERC-20 tokens that myetherwallet supports?

Theoretically yes... because all MEW (or MyCrypto) does is get the "public key" for your ETH address(es) from your Ledger device when you log in. So any Token "supported" by MEW/MyCrypto should be able to be viewed once you log in with a Nano device.

NOTE: You don't need to install anything other than the ETH coin app on the Ledger device itself... there aren't individual apps for tokens, ERC-20 support is included in the ETH app.

And before someone asks, yes you can store and transact with your kitties and other erc721 assets and collectibles there. Just connect it with metamask.

I sent BTC today via Ledger Nano S and chose Standard fee which was about 60+ sats/byte but when I checked the transaction, it used 45 sats/byte and plus sent BTC to another address including the receiving address I added on it's own. I checked Ledger Live and my BTC is still there but why does this happen and why it sends to another address and chooses to send less fee? Is Ledger too like exchanges that keep the remaining fee?

There is a difference between sat/B and sat/vB (virtual Byte). And that's probably what you are looking at here.
Since the SegWit soft fork, the maximum size of a block is no longer measured in bytes, but in weight units.

4WU = 1 vByte

The witness data of a (segwit) transaction weights 1 WU per Byte.
The non-witness data weights 4 WU per Byte.

That's absolutely not a problem at all. Just some conversion stuff.


Regarding your second address, this is a change address.
This is a crucial element of bitcoin, take a look at https://en.bitcoin.it/wiki/Change.

In BTC, there are no 'coins'. Just UTXO (unspent transaction outputs). Whenever you create a transaction, you are using at least 1 Input.
And if you are not completely 'using' it, you create 2 outputs, with one of them is an address of yours (a change address).

Is Ledger too like exchanges that keep the remaining fee?

Hell no!

Ledger has 0 control over your funds or anything else.
You always have full control.

^Oh so it's a Segwit thing then. Earlier this used to not happen and after that I started dealing with exchanges so never had to use my own wallet.

[HCP]

Just to clarify,

There were TWO parts to your query.The fee rate "discrepancy" is "a segwit thing" (as explained by bob123) due to the concept of weight units and virtual bytes... but the fact that there are 2 outputs created is simply "a Bitcoin thing". It is is not specific to SegWit transactions.

Encountered a new mini problem. I used my device after 3 months and noticed some line on the LCD which made the upper portion of the numbers invisible. Then restarted the device and it solved the issue but no clue why the issue even started.

They updated their Ledger Live but still it crashes while using it. Looks like they need to update their current version to solve the issue.

The good thing is that the problem was solved by itself, but the question is whether the problem will recur in the future. It may be just something completely harmless from a technical point of view, but it's also the first sign that the screen is starting to show the first signs of some kind of damage. If you were able to record that error, you can contact Ledger support, in most cases the replacement of the device is free. Something similar happened in this case.

On what OS are you using Ledger Live? W7 is known to do such problems, but W10 or Linux should work without problems. What you can try is uninstall Ledger Live, delete his folder with all files (C:\Users%USERNAME%\AppData\Roaming\Ledger Live) and install the latest version from Ledger.

I have taken out a video showing this display issue but since it got resolved on its own, I do not want to replace it now. Also, if they offer replacement, it would take days to receive the device and I need it to trade so would contact them if it happens again.

I have Windows 10. Their earlier Ledger Live version had a sync issue and used to crash in between a transaction and the problem happens now too but less often since I updated it.

I personally don't use LL because Electrum is all I need for now, but as far as I can see on Ledger Reddit, back a few months and maybe a year, a lot of people complain that their LL is very unstable and crashing o W10. At the same time, it works for some without any problems, even on the W7 - which gives the impression that it's not just the OS in general, but the combination of OS and PC hardware. For example, I can not run LL on W7, it crushes in just few seconds, and one user on the forum is made a firmware update on the same OS with some small problems.

What you can try to do is to uninstall Ledger Live/delete his folder, sometimes old and new files can create problems, and clean installation may be helpful.

I was trying to generate a new Bitcoin address yesterday to receive a transaction and ran into some small problems on my own. The Ledger Live software had some difficulties recognizing that my device was connected and the Bitcoin app was open. It just kept going in circles. After about 3 or 4 attempts where I had to close the BTC app and re-click on the 'Receive' button it finally got recognized and I was able to generate a new address.

Small glitch, I am just hoping it doesn't turn into something more serious.
Before someone asks, Ledger Live and all installed apps on the hardware wallet are up to date.

On Twitter they are asking everyone to clear their Cache incase they encounter such problems so may be try clearing your Cache. I did that too and now my software is working fine. Go to Settings > Help > Clear Cache.

[Pmalek]

@erikalui
I never seen that before so I didn't do any research on how to fix it either. Thanks for the hint, I will try to clear the cache and see if that solves the problems. Any known issues that have happened in the past to users who cleared their cache?

[erikalui]

^^
Looks like they have already addressed this issue via their new article: https://support.ledger.com/hc/en-us/articles/360010856259

Is this the issue you were facing yesterday? The other users were facing other issues like syncing errors and errors when updating apps.

[Lucius]

Any known issues that have happened in the past to users who cleared their cache?

Clearing the cache is an old trick used even on Ledger Chrome App, and this option is mostly used when the balance of the wallet is incorrect. When you clear cache, the app is forced to resync and download all data again. It's about the same thing that can be done in Electrum (though not the simplest way) by deleting blockchain headers, and that force Electrum to download the same file again.

I don't think this procedure can do any harm to the user in any way, it's a pretty harmless process.

[HCP]

Pretty much anything you do to Ledger Live itself is "harmless"... as you're really only affecting data on the PC... Like you could completely delete LL and all it's data and it's all pretty much recoverable from simply re-syncing once you've connected your device again.

The "dangerous" stuff is the stuff that lets you do things to the device that might wipe it... like the "repair your device"... or "device setup"... but even then, that's only "dangerous" if you don't have your backup seed mnemonic

[Pmalek]

Is this the issue you were facing yesterday?

Yes, that seems to be it. Although it wasn't related to any update. I was trying to generate a new Bitcoin receiving address but Ledger Live didn't recognize that my device was connected and the BTC app was open. Luckily I fixed it after a few attempts, without having to restart anything. It's good that they are aware of this and are working on a permanent fix, as the article says.

Again am facing a display issue that occurred few months back. That got resolved after restart but now it's not getting resolved. Couldn't even enter the code as numbers look the same. Sent them an email but got no reply yet.

I'm not sure I understand what you mean... there is an issue with the device itself so when you're asked to enter the PIN you can't see the numbers?

As I have already tried to explain to you in previous posts, your Nano S obviously has some sort of screen problem, and the only way to fix it is to buy a new device or ask for a replacement from Ledger. I think you will have to sacrifice trading for a while, or just use a reputable desktop wallet in the safest way possible until you get a replacement device.

Customer support is not instant, it may take a few days to get a response - and I think you should also consider the weekend, pandemic and summer holidays in the EU.

Beware of new fake Ledger Live Mobile Malicious app on google store!
Many people installed it.
