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?
