21  Other / Serious discussion / Re: Long shot... but does such an Android wallet app exist ? on: May 28, 2020, 11:09:55 PM
Honestly, I could try making you one. Last year, I was trying some React Native and did some apps to study the technology. Can't guarantee I would make it my priority though, since I don't have a lot of free time.

What do you have in mind? You add an address/xpub and it just shows up the balance (and maybe last transactions) in the screen?

It's not an standalone app and it's more focused on notifications on new transactions, but there is an Telegram bot I use called @MagnumNotifierBot which also shows the balance of an address whenever you want to.

Widgets I could live without...

But realistically something that lets me add public keys to watch wallets for at least Bitcoin and Litecoin.

Just about every app out there has trade this, sell that make accounts etc. But nothing I've found for specifically watching addresses that's not overly involved with a bunch of useless shit. Which is still nothing that I've found.

Anyway...

Most apps run in the background nowadays, so I'm not really worried about a few extra power draws or whatever. But maybe still have an option to turn that background option off for others, if you make it a public release.

But something that maybe runs in the background to check addresses for transactions say every 2 hrs and does a push notification when it finds one wether it's a withdraw or deposit.

But when the apps opened, it forces said update check and displays on screen accordingly.

But the GUI being something that shows a generalized interface that shows said address balances and maybe when clicked. Open a transaction page to show what's transpired on said address chains... so standard wallet stuff I guess.

But for me, be an android based app.

As for time. It's not like there's any real rush, so a side project is fine as long as it got played with from time to time. But if it became a priority for me. I could possibly pay down the line. But dor now it's a wishlist type thing.
22  Other / Serious discussion / Long shot... but does such an Android wallet app exist ? on: May 27, 2020, 12:22:52 PM
Is there a singular app that will, if not have other coins, at least allow me to set watch wallets for LTC and BTC ?

Maybe even have some sort of refresh button, provided it maybe doesn't refresh balances on app load.

Huge bonus if it has widgets for said wallets where by either tapping it, it refreshes if not has an auto refresh for every half hr or so.

If not, do we have any competant coders here that might be interested in building such a creature?

Ty.

I've looked at things like exodus. But hey dont even have a watch wallet option.

Ohhhh. If not a combined app. Two best singular options for watch wallets for BTC & LTC.

If and when something more secure is found, until it gets broke if it ever did. I would hope Trezor would offer some sort of discoint swap value for the more secure wallet. So like a 1-1... T for T etc. but at say a 60% or so reduced cost.
24  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 26, 2020, 07:42:37 PM

Ahh right, I see where the confusion lies.

So what you have written would be accurate in the case of someone restoring their wallet to Electrum by inputting their seed phrase. In such a case, as you say, the security of your hardware wallet would now be negated as your seed and private keys are now also stored in a "hot", internet connected wallet.

Using Electrum as an interface for your hardware wallet is different to that. You never need to input your seed phrase in to Electrum, and your private keys never leave the hardware wallet. In this situation, because Electrum doesn't have your seed or private keys, it is useless on it's own and can't sign any transactions unless your hardware wallet is also connected and unlocked. Electrum is only being used in this scenario as a user friendly way with a nice GUI to send instructions to your hardware wallet - your wallet, accounts, private keys, etc. never leave the hardware wallet and do not need to be imported anywhere else.
Thought as much, ty.

My wallets processing now, so since they're in Russia. I'll probably see a ship notification early tomorrow. Guessing then that it's in my hands by Mon at the latest if rona isn't messing intl mail up too much still.

Might need to get a longer cable based on what they send with it. But usb extenders are cheap enough.

But I'll be watching this package like aHawk. We dont have issue with mail theft but not taking a chance with something so small !
25  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 25, 2020, 10:26:50 PM
I only ask because from what I can tell. Restoring from seed would have to include private keys etc somehow or what good with it be if having to restore to let's say a new unit bec of damage or having to move coins bec of loss / theft.
Not quite sure what you mean here in terms of "including private keys". All the private keys on your wallet are ultimately derived from your seed phrase. If you import your seed phrase to a new piece of software or hardware, it will generate all the same private keys, and therefore all the same addresses, as your old wallet, and therefore give you access to all the same coins. You don't have to back up your private keys or even look at them, provided you have your seed phrase backed up.

Anyway, do ppl actually opt for electrum on a daily basis vs say hw respective sites like ledger / trezor ?

I just don't see how it (electrum) can make a hw remain safe wether its trezor or ledger.
As I mentioned above, Electrum is simply the interface to communicate with your hardware wallet. Your hardware wallet will generate a seed and generate a wallet, Electrum just lets you navigate it in a user friendly way. Your private keys never actually leave the hardware wallet, and no transaction or signing can take place without you confirming it on the hardware wallet. Electrum is also open source.
Exactly that is what I mean... you said it yourself, derived from the seed phrase.

So any device that seed is used on, can send / receive funds this eliminating the use of why have a hw wallet.

Ex.

Electrum Setup > What Kind (Standard) > Creste New Seed or Restore One

So further the ex.

Not so smart guy walks in loving his new hw wallet. Wants to use electrum with it vs say the wallets main / normal interface, however that works. So he adds his seed to electrum. Since all addresses and keys generate from that as you pointed out and I not so clearly asked.

If his system is compromised, even if it's not. His wallet is now technically negated bec funds can now be sent using electrum since the seed his trezor or ledger generated was restored to it (electrum).

Not saying many if any would try this, but in terms of electrum and hw wallets. I assume this is why it has the read from device option, at least on desktop ? Assuming it just reads public shit asking you to confirm on the device to send.

Sorry if I wasnt so clear before. But I've gotten some sleep, so maybe I'm clearer now ? Lol

Eitherway, ty for humoring me.
26  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 25, 2020, 03:26:55 PM
So download a copy of Electrum and keep it on a spare thumb (or micro SD etc.) drive with nothing but, better safe than sorry lol
There's no guarantee that would work either. Because of various bugs and vulnerabilities being found in the code, Electrum versions older than 3.3.0 no longer connect or sync. It's entirely possible (perhaps even likely) that a version of Electrum you download today will also not be able to connect 20 years in the future. It's also entirely possible that Electrum no longer exists 20 years in the future, and so there are no servers being run for old clients to connect to.

But that's I guess a bridge crossed if and when its approached since I assume, even if it's not too difficult, is a somewhat involved process.
After you set up your hardware wallet for the first time and write down your seed phrase, I would taking a note of the first address generated, wiping your wallet, recovering from the seed phrase you wrote down, and checking the addresses match, as a way to verify the seed phrase you wrote down is correct. Too many people only discover they have made a mistake in writing down their seed when they need to restore from it, at which point it is obviously too late.
Fair point about electrum.

I like to try and think ahead sometimes.

But that being said, I'm usually pretty good about not messing up sm electronics in any way. But it also probably wouldn't hurt to get something like a model one down the road and restore the seed on it. Keeping it as a protected backup with the Model T being the always used when needed device. Only using the model one incase of damage to the T or quickly needing to move coins due to damage or loss / theft if I take the Model T out with me for some reason.

As for testing the seed, I hadn't considered that... so TY... seriously !!!

All of that said. I did download and install electrum on the desktop just to check it out since i never have before. I noticed it had diff wallet features. Like watch only, which really any app or program can do that. Might keep it on my phone for that aspect (watch only).

Unless you know of something better that does watch only but can also say, notify me of incoming / outgoing transactions via something like a push notification like many games, banking apps do. But with at least btc and ltc addresses.

But it (electrum) also has a seed function it seems, among others like read from device.

But who in their right mind would use that (seed function) if they didn't need an emergency move for some reason ?

I only ask because from what I can tell. Restoring from seed would have to include private keys etc somehow or what good with it be if having to restore to let's say a new unit bec of damage or having to move coins bec of loss / theft.

So it would be like why have a hw wallet if someone is dumb enough to use a seed on electrum aside from needing an emergency move. Even though I suspect that might be the main if not only reason. But you never know with some people.

Anyway, do ppl actually opt for electrum on a daily basis vs say hw respective sites like ledger / trezor ?

I just don't see how it (electrum) can make a hw remain safe wether its trezor or ledger.

But I do like the idea of stand alone programs which currently it seems only ledger has but was obviously not a swaying consideration for me to get it instead of the model t.

Anyway, sorry for the run off there with all that. My mind speeds like I'm on coke when I dont sleep, and I didnt sleep last night. I at least hope I made sense lol

But the run offs aren't always a bad thing...

But I feel, based on trezor alone. I have everything i need to know known. Since this reply was mostly an electrum thing lmao

Ttyl and ty for humoring me.

Gonna try and go relax before this headache turns into something else.
27  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 25, 2020, 02:08:37 PM
what would happen to the funds on the wallets if both sites (trezor/ledger) were to just completely disappear, servers and everything, and for whatever reason a user like me was not made aware until way after the fact or something.
The wallets don't actually store your coins. All they store is the seed phrase and private keys to the addresses your coins are located at. Your coins never leave the blockchain. Similarly, the software that Trezor and Ledger provide is simply an interface to interact with the private keys stored on the wallet.

In the event that the company ceased operating, and you no longer had a copy of their software or were able to download it from anywhere, then you would have two options to access your private keys. The first would be to use a different piece of software which supports your hardware wallet. The most popular example of this is the Electrum wallet (electrum.org). You can use Electrum with both Trezor and Ledger devices to access any wallets, accounts, and keys stored on them, view your addresses, sign transactions, etc.

The second method, which you could use if there was no software which would interact with your wallet, or if you lose or break your wallet altogether, would be to recover from your seed phrase. Given that BIP39 is used so widely at the moment, it is almost certain that in 15-20 years there will be software that supports it, even if we have moved on to something else and BIP39 is obsolete.
So download a copy of Electrum and keep it on a spare thumb (or micro SD etc.) drive with nothing but, better safe than sorry lol

As for recovering from seed phrase, guessing that's the most unlikely scenario needed unless the wallet was, like you mentioned, damaged in some way. But that's I guess a bridge crossed if and when its approached since I assume, even if it's not too difficult, is a somewhat involved process.
28  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 25, 2020, 01:41:31 PM
One thing I probably should have thought of asking before spending the money that I did for the Model T, as unlikely as it would be for one let alone both for this to happen to. At least for what I'm guessing would probably be 15 to 20 years if it all.

Just for shits and giggles, what would happen to the funds on the wallets if both sites (trezor/ledger) were to just completely disappear, servers and everything, and for whatever reason a user like me was not made aware until way after the fact or something.
29  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 25, 2020, 10:22:12 AM
I'll read that later, but even if I personally had your drive. Unless I had whatever pass phrase is set up. I couldnt do anything with it. Unless I missed something, I would need your drive and the wallet / system its tied to, to steal your funds. But just the drive itself, last I knew, wasnt even close to enough.

Let’s take a hypothetical situation of someone coming into the physical possession of your hardware wallet, and that this wallet has some kind of vulnerability that can be exploited with the help of cheap equipment and little technical knowledge. This currently exists with Trezor models which are extremely vulnerable in case the user has not set up passphrase, the seed can be extracted within minutes. The conclusion is that all those who are not aware of this vulnerability and do nothing to insure themselves, have at least one additional risk when it comes to protecting their assets.

For now, Ledger is definitely at an advantage because there is no such vulnerability - if there was one, Trezor would surely make it public. But what some people don't like about Ledger is the fact that it's not open source, for which Ledger again gives somewhat logical reasons.

Every device has its weak points, it's only a matter of time before someone discovers them. What plays the biggest role in the case of hardware wallets are possible remote attacks, which have not been recorded so far (or at least no one has made it public).

Broke down, bit the bullet and bought the Trezor Model T using some of the LTC I have.

Congratulations on your purchase, although it didn't seem to me that you would choose the most expensive option at the moment. Just a week ago you could get Nano S for some 30+ EUR, and Trezor T is 180 EUR now (VAT included).
Attacks aside. Short of someone stealing it from me / breaking into my home. As you or someone else pointed out. They'd have to know what their doing and have the right equipment. Would hope by the time i know it's missing I could xfer anything on it.

Not to sound like a smartass, but who wouldnt setup a passphrase? Even if it came as an after thought. Or maybe it's just that no one considers it. I'm not much of a techie in terms of things like this. But if it's an option of added security, I'm going to use it.

As for my purchase, it was sort of an impulse buy. But that being said. I do love the larger screen. They also seem to have better support I'd rsther have when needed than need it and have Apu from quickemart. Or better yet. Tech support from the show IT Crowd.

I could have gotten the model one. But something kept nagging at me to get the T.

But ya, $162.46 USD (149 EUR) wasn't easy but felt kind of right besides hurting while doing it lmao

Also, as for remote attacks. Unless I'm overly tired and not on the same page as you. That only seems feasible with the Nano X and its BT... unless your also considering how someone may leave the wallet connected to a computer even if its not actively being used (the wallet).

Anyway, going back to the trezor vulnerability. Might sound stupid, but even with a passphrase. Isnt that attack still feasible but just taking longer ?

even then, based on what I know. Wether its trezor or ledger, physical access on the drive is not enough in and of itself.

Yes it is.

https://www.ledger.com/chaos-communication-congress-in-response-to-wallet-fails-presentation/

However the chances of someone breaking in, finding it, knowing what it is and knowing how to get at it are on the astronomical side. And it's also neutralised by having a 25th password. But who knows whether new angles will be found?

For me online security is obviously the big one and so far they're fine.



That was a good read but I'm still 50/50 with me leaning a tad more towards ledger. Either way they both for the most part seem like really great choices, did come across the model t for trezor. That's an interesting price tag. But really. For just btc and LTC. Either the trezor one or nano s seems like they would be the more than sufficient models. Setting aside what seems like possibly better security in the higher models which one might then argue. If you're going to get a hw wallet. Just go big or go home.

Def more research to do but of the what seems like 6 diff. companies. They're the two to really consider.

33  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 24, 2020, 10:23:42 PM
I'm probably not getting one, whichever one, until around xmas when I put some coins away for a while... at least 2 yrs... depends.

If the value of the coins you own is a few hundred $, maybe you can live with the knowledge that you can lose them at any moment. But when it comes to a few thousand dollars, few can afford such a loss - and there are users on the forum who have lost very large sums of coins because a $50 hardware wallet was too expensive for them. It is your decision whether to invest in security or not, but anyone who understands what crypto is will tell you that it is not wise to keep such things online.

I see you're a trader so you can’t avoid having a certain amount of funds online, but in any case the correct option is to move them from the crypto exchange when you stop trading. Even a desktop wallet can be a safe option if you take all the precautions.
80% of what I have is secure even if my house burns down with the rest on coinbase pro. So ya. I stand to lose roughly a grand if shit hits the fan but like you pointed out. I trade actively all year, so theres an inherent risk.

Wo wether it is now or xmas time, it's still a gamble. But one in already in.

But fwiw, my main account is MoreBloodWine. So I'm not necessarily new to crypto. Just gotta finish up some stustufstustuff before using it again. I had lost it for a good long while and only started recently finishing some things up before I use it again.

I have a Trezor 1 and a Ledger Nano S.

The Ledger has been abandoned. There's something about the way they operate I dislike. In this game you should be humble and open and they certainly are not. Trezor's attitude is better and more communicative so they're the ones I stick with.

I am starting to wonder about the future of hardware wallets, more holes are found every day, but since all current ones need physical access to exploit I'm not going to sweat it until that changes.
even then, based on what I know. Wether its trezor or ledger, physical access on the drive is not enough in and of itself.

But I am 50/50 with a slight lean towards ledger.
34  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 23, 2020, 08:37:35 PM
Would have to double check,  but as far as avoid issues goes. As long as trezor does LTC which I believe it does. It, may be the better option. Def more reading to do.

Trezor supports LTC. You should read about the unfixable vulnerability found in Trezor devices and their response to the described attacks. They are very unlike to happen and require a physical access to the device, but everyone should be warned about it before making a purchase. Ledger is not vulnerable to any (publicly known) attack at the moment, but because of Secure Element, it is not fully open-source.
Oh, given the nature of the item(s) at hand. I'll most def do my due diligence as one may say. I'm probably not getting one, whichever one, until around xmas when I put some coins away for a while... at least 2 yrs... depends.

Ty.
35  Bitcoin / Hardware wallets / Re: Hardware wallets... on: May 23, 2020, 08:03:11 PM
Well, as far as coins go, I still dabble in BTC once in a while but my main playground is with LTC. But ya, I do like the Ledger design better myself not that that means much.

But seems like it, Ledger, may be the way to go if and when I get a HW wallet just for the added security of even say storing a wallet file on a disk / thumb drive off line.

Would have to double check,  but as far as avoid issues goes. As long as trezor does LTC which I believe it does. It, may be the better option. Def more reading to do.

36  Bitcoin / Hardware wallets / Hardware wallets... on: May 23, 2020, 10:08:31 AM
So I'm familiar with Trezor, by name only, as I saw them advertised a lot before launch. Been seeing some other ads on Facebook as of late for a diff hardware wallet called Ledger, looks more fancy, not that that really means anything.

That being said. Of all the currently available HW wallets, what do you use if any, and why ?

I do know the trezor is ~$55 while Ledger which comes with a nano ver or some such shit is ~$150.

Been contemplating getting one vs a locally stored wallet file / paper wallet etc. for moving some coins off of CB after making a few more trades.

Got the MoreBloodWine account back, will be working on it over the next few days to get "lockdown trust" removed.

This will still remain a backup account to be safe.

I do not think anyone will help you as you are newbie and trying to sell venmo which can be reversed at any time. If it could be not reversible payment then many people could help you.
Dont need it any more.

Fair enough.

Yes bro. So let me know if you can trade with me or you wait for others first
Gonna wait a bit and see what happens with other ppl. Kind of already screwed on time, so waiting a bit longer is no real biggie at present.
