Topic: Stack wallet for mobile? (Read 661 times)

Are you referring to coinjoin? While some mixers may use coinjoin to obfuscate their transactions, I don't recall any service publicly saying that. I wouldn't be surprised if it is just a fork of coinjoin, to be honest.

Hahaha it seems that it does look outdated by implementing the BCH ecosystem, I don't even know when I last used BCH LOL.

it is available on the Stack Duo Wallet and is specifically used for Bitcoin and Monero wallets, separate from stack wallets.
While Stack Wallet is a fully open source multi-wallet with a user-friendly interface.

Cashfusion is for BCH right?
I don't know who still uses BCH in 2023/24,except maybe Roger Ver and his friends  

Except we are not talking about Bitcoin here.  
This would be possible to have in Bitcoin, but fees would be unacceptably high.

If you are using Stack wallet, do you know if maybe they have coin control option for Bitcoin in their app?
I couldn't find anything about that on their website and github page.

EDIT:
I can confirm there is Coin control and PayNym available in Stack wallet, but for each new added shitcoin you need to generate separate seed words 

UPDATE
Stack Wallet v1.8.1 Pre-release

Stack Wallet provides the latest updates with the addition of Cashfusion Functionality and Fixed ETH and ERC-20 synchronization issues.

CashFusion itself is a fully decentralized privacy protocol that allows anyone to make a multi-party transaction with other network participants,
so this process will obscure real user spending which can make it difficult for chain analysis companies to track such transactions,
The mechanism seems to be almost the same as the Bitcoin Mixer, but CashFusino combines other people's transactions causing confusion.

And Epic Cash.

In addition to that, it appears that all of the nodes are disconnected by default ^{[it's a nice touch]} but having said that, if you connect them, it no longer gives you the option of disconnecting them ^{[unfortunately]}.

Interesting update from Stack wallet is release of new version of multicoin wallet that works on all platforms, including Linux, Mac and wind0ws!
I have been testing this wallet in last few days on computer and it's not bad at all, they added Tor support (not working for Monero), and interface is nice, but warning that this is still pre-release v1.8.0, so expect some bugs.
It looks like Stack was working with Passport Foundation developers on this project:
https://github.com/cypherstack/stack_wallet/releases/tag/build_191

It seems that there are still many bugs that must be fixed from either Android or iOS.
and currently, the developer is also still focused on improving Stack DUO, which has also released a Stack DUO update a few hours ago.

Released Stack DUO v.1.0.4 build 7 for all OS (Android, iOS, and Linux).

Release notes:
- Mnemonic passphrase now taken into account with backups
- Tag color fixes
- Orange theme addition
- Address labeling and management (desktop)

https://twitter.com/stack_wallet/status/1643396308919787520

As an early user, I try to provide some feedback that may be needed, so that there are improvements from the developers.
I'm not using it as a primary repository, but trying to explore the features available and maybe some other bugs might be found.

Another strange move by them, but perhaps they're planning to create a dedicated website for the Stack Duo.

I tried replicating it with my Android device ^{[for both of their wallets]}, but I had no luck so I checked their Twitter timeline and they did release a statement earlier mentioning there's "a major bug on iOS that causes crashes ^{[it has something to do with their current Monero library (they'll change it soon, but no ETA yet)]}".

As a user of an Early Development application like Stack wallet, it is not recommended to be used as secure storage.
It's like a beta version that still needs some updates due to errors and such. We as early adopters become testers and if we find a bug,
we can give feedback so that it can be fixed immediately.

That means a lot of bugs in the mnemonic passphrase section should be fixed.
But there is a bug that is still not fixed in my opinion.

When you enter the wallet section and want to return to the Home Screen, the Wallet delay of a few seconds cannot be pressed on anything
(not until it crashes). That could be a bug in the appearance of the Home Screen. 

Have successfully restored it (balance) by choosing the generate new address path. Also good as a step to experiment or test in a wallet that is still in early development.

That's right. It is simply not an option to store large amounts of coins on mobile wallets.
Stack Wallet is again asking users to update again after the last update on March 29 in the goole play store.
This time the update is more about the mnemonic passphrase.

The screenshot feature may have its pros and cons, but it can be optional whether you want to use it or not.  dangerous or not, it depends on how to secure the screenshot results.  but I prefer to write down the phrase seca manually on a piece of paper and then copy it on a steel plate so that it lasts longer and doesn't get damaged.  This stack wallet is also still under development, maybe this is just a temporary feature or it's intentionally using screenshots.  because other wallets generally disable screenshots.

To take a screenshot of your recovery phrase may be stupid, but it is way more stupid to forget your phrase and loose access to your coins. If you store the screenshot in the iCloud for example it is secured by end to end transcription and 2 factor authentication. I would not do it (and use hardware wallets anyway) but honestly it is probably better then what 50% of Bitcoin users do.

It can also be a bit confusing they didn't separate wallets on their website, and there is not much information except on twatter.
I don't like option to take screenshot of something so sensitive as recovery phrase and keep it in digital form, when it's much better to simply write words on paper and keep them offline.
They probably wanted to reduce risk, but this is still an early development so they could change things later.

I don't feel comfortable enough to use real bitcoin so I might test it out with Bitcoin testnet again to compare difference between regular Stack and Stack Duo wallet.
It should be the same procedure for recovering wallet with mainnet and testnet.

Sorry for not describing it in a clear manner ^{[my bad]}, but you nailed it... By default, the first generated Bitcoin address has a derivation path of m/84'/0'/0'/0/0 ^{[change address is m/84'/0'/0'/1/0]} and for the second and third generated Bech32 addresses is m/84'/0'/0'/0/1 and m/84'/0'/0'/0/2 respectively. I only used that particular derivation path as an example, but stack wallet/duo also supports Legacy & Wrapped segwit, and earlier, I did my tests for these two as well.

I completely forgot that feature existed ^{[out of habit (SMH)]}, but since I ditched my stack wallet seed phrases a week after making the small payment tests, I would've not been able to use the "detect existing accounts" feature in Electrum because the seeds that I used earlier, didn't have any pre-existing accounts attached to it.

You confused me a bit with this reply. Are you saying that you couldn't find the generated Stack wallet address by importing the seed into Electrum even after increasing the gap limit to 2000? What derivation path does Stack wallet use for Bitcoin by default? You mentioned m/84'/0'/0', but that's the standard one for Bech32 addresses. What were you scanning before that?

If you tick the scan common derivation paths button (or whatever it's called), does the software find it?

It's worth noting that this one doesn't allow you to take a screenshot of the recovery phrase page, but the other one still does ^{[quite strange]}!

Speaking of Electrum and derivation paths, I had no luck finding them ^{[I even increased the gap limit to 2000 and also used ismine("type your address") in the console, but it kept showing false]} when I used the exact derivation paths that stack duo ^{[this probably applies to stack wallet as well]} shows for each of their addresses, so in case someone else stumbles onto a similar issue, just go with what Electrum suggests by default ^{[until account (e.g. m/84'/0'/0')]}.

I think this could be the issue with derivation paths, but you should be able to recover seed words to any other bitcoin wallet with same format.
Mobile wallets are not ideal and I would never keep any significant amount of coins with them, especially if they are in early development phase.

Stack wallet released new version called Stack Duo that is only used for Bitcoin and Monero.
I think this is perfect solution to avoid complications with other shitcoins, and people can still use full version with other coins if they want.
Please note that Stack Duo is currently pre-release version, and I don't suggest anyone to use it a s their main wallet, this is still testing ground.


https://github.com/cypherstack/stack_duo/releases/tag/build_004

PS
This is not-mastercard logo  

After I checked the stack wallet is not 100% or still in the initial development stage of the application. From the trials I did, it is likely that you took the address in the stack wallet based on the results of the generate address that you pressed so that when you update the application, the address you use has changed to the initial address so that the command to re-generate the address conveyed by SFR 10 can be a solution.

Now try checking the address again on the main display of your stack wallet application, it must have changed again.

---

Congratulations you can get back the balance stored in the stack wallet.

Synchronization and connection issues can happen. The first thing you do in that case is check your receiving address/addresses in a blockchain explorer. If there aren't too many of them, of course. There is no need to worry if you don't see any outgoing connections that you didn't initiate. After that, try to fix whatever is wrong with your connection. Worse case scenario, you have to abandon Stack wallet and import your seed into a different client, like Electrum (ticking the BIP39 seed box during the setup stage). Stack wallet generates standard BIP39 seeds for Bitcoin that you can import in other wallets if needed.

Yes. Thank you very much SFR10 for your command to try to do some generate address and the result is that the balance at address bc1q7d3yfaj36uwylgu33gr2uujr8m9l65pec3rqrg I can get back.
I was panicking too, but this is a valuable experience in using Stack Wallet.

You're right. After their last update, they've added a new feature that we have to enable.
BTW, thanks again.

When I was testing it a couple of months back, it had synchronization issues... Are you sure it was completely synchronized at the time or did you try to connect to a different node?

You might want to double-check the order of seed phrases and while you're at it, try to generate a lot of new addresses ^{[it might help with finding the missing address]}.
^{- With regards to the underlined word, I believe you meant to type receiving instead.}

---

BTW, it appears that they've added the coin control feature, but we have to enable it from the advanced tab.

Update:
You're very welcome, I'm glad it worked

Don't. I just lost about $50 in Bitcoin after using the Stack Wallet wallet. Don't use this wallet while it's still in the early development stages.

https://mempool.space/address/bc1q7d3yfaj36uwylgu33gr2uujr8m9l65pec3rqrg

Initially the balance showed about $50 in BTC in the Stack Wallet App, but when trying to send to an Electrum address from Stack Wallet the balance was zero.
I deleted the address because I had the 24 words saved.
When I entered the 24 seed phrase, the balance was zero and the sending address changed from bc1q7d3yfaj36uwylgu33gr2uujr8m9l65pec3rqrg to something else.

I just installed the Android version of the Stack Wallet app on my smartphone and it's true that Stack Wallet is not a bad wallet. When it finished downloading, I opened it right away and the process for address generation wasn't difficult. Stack Wallet is similar to Trust Wallet in the process of getting addresses. Stack Wallet only asks us to choose one phrase out of 24. But the difference might be that it is open source and not.

I think what they wrote about Stack Wallet from the inside look is true, it looks very ideal for anyone who uses it.

If I remember correctly, ChangeNOW has pretty high fees when bigger amounts are concerned. It's ok for smaller sums that you otherwise maybe couldn't even swap on standard exchanges because the amounts are under the minimum trading limits. Try to check what the difference in the rates offered on ChangeNOW's official website are and what you see in the Stack Wallet. That way we could know approximately how big of a premium they charge.

Like I mentioned previously, KYC is a possibility with ChangeNOW and their partners:

https://changenow.io/faq/kyc-aml-procedure

Yes, not necessary, some wallet can make use of smart contract decentralized means of exchange using swap function in a way you can exchange a coin and its tokens.

I just do not want to make a final conclusion because of this:

https://stackwallet.com/



But while I tried to exchange monero and some other coins, this is what I saw:



You can see ChangeNow which is an instant exchange. Probably because there may be other ones is the reason I did not just make a conclusion but generalized it to make use of instant exchanges, probably there may be another one too which may not be an instant exchange, but I doubt that for now.

Not necessarily. It depends on the platform. Instant exchanges also have their partners and liquidity providers, and they might be the ones that want to verify who is sending the money and what is the source of it. It happens. You can come across scam accusations where instant exchanges have confiscated funds (actually their partners have) and users are being asked for KYC.

Such exchanges are instant exchanges, they will not ask for KYC, but as you know, all instant exchanges are centralized exchanges, they can seize users coins and demand for KYC.

In all honesty, the Stack Wallet is also still being tested and developed according to the info Lida93 saw when he downloaded his version from Google Play. Maybe it wouldn't be a bad idea to mention in the OP that the wallet is still in development stage.

I found out some more interesting things after reading their website.

- You can apparently exchange the coins that Stack Wallet supports even for assets that aren't' supported by the wallet. That's because the whole process is done through 3rd parties. I guess you have to provide the exchange with a wallet address from somewhere else, and that's where they will send your coins. If there is liquidity, this is great news. But does the wallet mention the names of the 3rd-party exchanges they work with? Maybe there is a chance the exchanges ask for KYC.

- Stack Wallet takes a cut from each swap. They explain on their website that's how they make money. To get the best possible rate, one can always compare the in-app offer to what the exchange offers when you visit its official page directly.     

I didn't have issues like that, but I tried running Stack wallet in android emulator and everything worked fine until I went to settings and started to change things there.
After this wallet started crashing randomly so I had to reinstall and reset everything.

While testing this I found out another similar open source multi-currency wallet that respects privacy, it id available for Android/iOS, and its called Elite Wallet.
Elite is supporting Bitcoin, Monero, Litecoin and Haven coin with it's xAssets like xUSD, xEUR, xAG, etc.
Note that is new wallet so only use it for exprimental testing purposes!

I am not debating whether one should make a backup of their seed generated on a phone or not. You should, of course, do that. I got the impression that you tried to say that the seed on such devices is offline. That's why I commented that it wasn't created in such an environment and should, thus, not be considered as being offline and as safe as proper offline solutions. Assuming that your phone is infected with malware, your passphrase isn't going to help much either. Because it's again created on that same (potentially vulnerable) system.   

After doing further tests, I noticed there's an annoying synchronization glitch and bug ^{[e.g. if you try adding different nodes, 7 out of 10 times it works for the mainnet, but I was never able to get it to work for the testnet]}!
^{- Anybody else with a similar experience?}

It's my first time of hearing about this stack wallet and as someone looking for better open source wallet with multi choice coins, I just installed it from Google play store right now, but one thing I observed while I was about to download the wallet is that the developers made it clear under the install click on Google play store that " the app is in development", if I understand this, it means it's still going through further improvements on its features as it encourages users to provide some feedback as recommendation where necessary. 
I'll take time to review it anyway, I hope it meet my expectations.lolz

This is the first time I heard of stack wallet, Never try it yet. But according to your a little bit review about it sounds
better when we use it. Maybe later on I will try to install this one to give it a try I also trust with your

explanation as well. But if there is something I find out in which I think there is a problem of course I will not recommend it
too other to try it, but for now, is under my observation and review also.

I am not sure if they used it or not?, I just found Bransfer when exploring the discovering all applications on the page. So I don't know if it just listed not as default they used for. But, I think it's not more crucial, some people still make sure of the price in which they believe.

Your statement doesn't make any sense to me.
Nothing can be less secure if you have multiple fingerprints in one device, for example you can use one fingerprint for phone, and for wallet you can use different finger with different fingerprint.
Or just don't use any fingerprints at all, because it's OPTIONAL for everything I mentioned.
Don0t get me wrong, I would be the first to complain if fingerprints are made mandatory for anything.

The point is you can create an online wallet, make a paper backup, but you still need to protect the paper backup just as you still protect the online wallet. it is not because you have online wallet or having low amount of coins on it that will make you not to still protect it, but just that it is online wallet the reason you have low amount of coins on it, but at least, you will still protect the wallet and the paper backup despite the wallet being an online wallet. Won't you still protect online wallet? Just that 90% or more of your coins can be on cold wallet just because you know that online wallet are vulnerable to online attack, but not that you still not protect the small amount of coins you have on online wallets.

I don't want to sound like I am protecting instant exchanges or any other exchanges for that matter, but for the accuracy of the information, it's not the exchange that blocks your coins and asks for KYC. It's one of their trading platforms they work with to facilitate those swaps. ChangeNOW just informs you, hi KYC is necessary because that's what their partners asked them. For an instant swap to happen, multiple transactions take place in the background that the end-user doesn't see and doesn't need to know about.

Transaction 1: Your deposit to the swaps platform.
Transaction 2: The swaps platform transfers coins to a liquidity provider.
Transaction 3: The liquidity provider exchanges coin A to coin B.
Transaction 4: Coin B is sent back to the swaps platform.
Transaction 5: The swaps platform sends the coins to your address.

I am not sure about the last step. Maybe the 3rd-party sends the coins directly to your address. Anyways, there could actually be more transactions if you are exchanging two unknown altcoins one for the other and there is no such trading pair available. In that case, the instant exchange would first need to have its partners swap the unknown coin for something familiar like BTC, USDT, or ETH, for example, and then get the asset you want in the following transaction. 

In fact, that's the same way that swaps work on some of the services on Ledger Live or Trezor Suite. If you open the native apps, read the TOS, or initiate a crypto to crypto swap, you will come across information that 3rd-parties might ask you to verify your identity. Sometimes it works without it, other times it doesn't. It probably depends on the amount and the history of the coins.   

It's a hot wallet that is connected to the internet. Thus, the seed phrase is not offline despite being written down and stored on paper/steel/some other way.

There's also Particl + a few testnet coins ^{[tBitcoin, tLitecoin, tBitcoin Cash and tDogecoin]}.

Just did ^{[I only tried the incognito mode (screenshot)]} and I was surprised it allowed me to take a screenshot of the recovery phrase page ^{[I do know this shouldn't be used as our main wallet, but nothing stops a newcomer from making that mistake]}!

Unfortunately, it doesn't have any of these features, but at least it gives you three choices for the fees ^{[fast, average and slow]}.

---

BTW, there's also a desktop version ^{[linux only]}.

If fingerprint is enabled on the phone, why enabling fingerprint to access the wallet too is what I meant, it makes the wallet to be less secure regardless of the small amount of coin you have using the mobile wallet. Anyone can go for fingerprint, but letting them know how dangerous it can be is not bad at all.

Including passphrase to generate different keys can be of people's preference, just like I have implied before, not using it can make some people to feel insecure as they keep their seed phrase offline, having a passhrase can be of help regardless of the amount of coins they have, if huge or not. Also the point is that passphrase is included in BIP, it is part of bitcoin improvement proposal that was implemented, any bitcoin wallet that do not support it do not have any excuse, it supposed to exist on all bitcoin wallets but to be optional.

Are you sure this refers to the same app? Looks different to me. Or are they related in any way? I don't see Bransfer being mentioned in the link OP shared either. Other than ChangeNOW which was mentioned above, it seems like they also use SimpleSwap according to their Twitter. CMIIW.

I can understand if an average is used if the wallet doesn't necessarily use an exchange to swap the coins to prevent an 'unfair' rate. I think that's the trade-off a user need to accept if they don't want to stick with one exchange. But I'd avoid ChangeNOW or other instant exchange services if possible since they can flag your transaction and ask KYC at any given time.

Because they use Bransfer, that possible they use that application to collect all crypto exchanges API in one application. But I don't know how important that is. because when I want to trade my crypto, I always use price data from an exchange I want to transfer. it is real and more accurate than average.

You don't have to use fingerprint, but all smartphones already have biometrics like face and fingerprints, so you shouldn't use any smartphone 
Passphrase is a different story and I like it, but I don't see a point in using it for mobile wallets that holds small amount of coins.

It's all privacy based coins, wownero is monero fork with better privacy but it's a meme coin like doge.

Looks like they have two methods for backup, but I am no sure seed words are compatible with other BIP32 wallets.
I didn't test wallet with transactions, but I plan to test in soon and see if there is coin control and other features.

When you want to create a bitcoin wallet, it will generate you a BIP39 seed phrase which I used iancoleman to check if true or not. For each coins, it will generate you different seed phrase which depends on the coin of your choice that you select, you can only select one coin, no box available to check the coin of choice to make it a multi currencies wallet for a single seed phrase, it is different seed phrase for each coins.

Another type of backup is the file backup which can be 'auto backup' which backup your wallet data every 10 minutes on default but you can select other time range for the backup. The other is 'create manual backup' which is also the backup of the wallet files but just  in a way no automatic saving of wallet data every 10 minutes or the time chosen.

File backup can restore all the wallets (bitcoin and including all altcoins wallets) that you generated on the wallet app, unlike seed phrase, one seed phrase for one coin wallet, another seed phrase for another coin wallet. So both backup can be necessary to people. The file backup is encrypted.

If no comment about this, I will find a free time to review the wallet more and give answers to these. If it has fee customization, I still doubt it would have coin control because most wallets do not have it.

Quite a weird choice of coins to support. I have never heard of Wownero or Epic Cash in my life.

So, that's where it got it's name from. It's multiple standalone wallets stacked up to be used through the same interface.

So, you are given a choice to use standard seed backups or their own native backup method or how does it work? Can the Stack wallet recover wallets created by other BIP39-compatible bitcoin cliets?

Too bad, that's the main thing. It would be like deciding what car to buy, but without giving it a test drive. Any information about coin control, UTXO selection, or the liberty to enter your own fees? 

First of all, I do not like a wallet that encourages fingerprint, I mean that makes it noticeable and possible during the wallet setup. Secondly, I like passhrase, it makes me to feel secure while I backup my wallet offline on paper, but the wallet do not support passphrase, even I wanted to import BIP39 passphrase along with seed phrase but that was not possible.

It is a HD wallet for bitcoin, I did not tried altcoins but you can even generate new address on the wallet if it is bitcoin.
I did not see anything like pay-to-many on the wallet, it is not supporting it.
It is not supporting lightning network
It supports segwit version 0 (bech32)

I never tried to use this wallet but it seems good if we know this wallet better, I've done also a short research, and I see not bad at all though there are minor problems like coins support I think that is very common on a decentralized and open-source wallet.

In addition, they also have Twitter and Reddit accounts which are also good to follow if you're interested in them.  I read on Twitter they have giveaways.

Yes, they're and it's Changenow.io which is I think NOT good for me, it has a high fee.

Does it support HD wallet function for BTC ?
Does it have pay-to-many feature (in single transaction) like bluewallet?
Lightening support?
What types of BTC addresses supported ? ( can we access legacy and bech32 with same key here?)
From where does it collect the price feed for crypto-to-crypto conversions? Anyone got more info?

Never heard and tried this wallet before. Also i never used an open source multi crypto wallet before unlike coinomi and trustwallet which are opposite, or I guess there is no open source multi crypto wallet yet so this should be a must to try.

There are not many open source Bitcoin wallets and even less of them for other cryptocurrencies, but recently I saw one called Stack wallet and I didn't saw anyone talked about it in forum.

I decided to install Stack wallet and make a quick test to see if it is any good or not.
Website stackwallet.com is saying that Stack is open source privacy-preserving cryptocurrency non-custodial wallet, and it supports Bitcoin, Monero, Bitcoin Cash, Firo, Epic Cash, Namecoin, Wownero, Litecoin, and Dogecoin.

Installation was quick, I was asked if I want privacy or regular mode (with coingecko prices), and for each coin I have to create new wallet, add name and generate seed words.
You can select your own Bitcoin node, and there is built-in exchange in wallet, but I think they are using some third party centralized exchanges.

 

Stack wallet have backup option but this is NOT compatible with any other bitcoin wallets, so I suggest keeping seed words instead of custom backup.
I didn't receive or send any transactions with Stack wallet, but this could be alternative if you want to keep few shitcoins along with Bitcoin as pocket money, don't use this wallet for larger amount of coins.

Stack wallet github page is available but I still didn't saw anyone confirming if their code is verified by wallet scrutiny or someone else:
https://github.com/cypherstack/stack_wallet

From my short testing  I can say this is not a bad wallet, but alternative called Unstoppable wallet looks and works much better for me.
Another alternative open source wallet is called Cake wallet, that is oriented more towards Monero, but Bitcoin and Litecoin are also supported.

Did anyone else tried this wallet and what do you think about it?
