Bitcoin Forum

We have lot of choices for bitcoin in the crypto industry but there are very limited choices when it comes to open source, non-custodial, multi-crypto wallet so let's hear your apps and it may be useful for the altcoin holders to choose the right wallets for long term storage.

Android/IOS = Unstoppable wallet (https://unstoppable.money/)
Desktop = crypto-com/chain-desktop-wallet (https://github.com/crypto-com/chain-desktop-wallet)

Both these wallets support multi-crypto and open sourced so anyone looking for alternatives for Trust wallet, Mycelium and Coinomi which al are closed source then let's give it a try to the apps mentioned above.

I also started making use of an unstoppable wallet recently after my thread on the technical board. A lot of members recommended it for use, and even the forum administrator is among those who recommend the use of the wallet. You can check out the coins that are supported by the unstoppable wallet here: . Coins Supported by Unstoppable Wallet  (https://www.cryptowisser.com/wallet/unstoppable-wallet/coins?page=1)
 
I also make use of the Metamask wallet. I don't know if they are open source, but it's been part of the oldest wallet I have been making use of in the past, and there is no problem. It has both desktop and mobile compatibility, but the desktop version has more features built into it than the mobile version.

Metamask is also open source wallet but it doesn't come in the form of an application but in an extension form that supports limited networks compared to other service wallets but its still one of the best for token storage but only due to the limited network and not having dedicated app even after all these year is a negative in my opinion.

Imo, that's not the biggest issue with Metamask. It is the fact that there's almost no privacy when using metamask because I remember sometime this year when they put out a public announcement that they have to openly track user footprint using their RPC from sister company — Infura. That, and also the fact that metamask currently have one of the worse UX despite being the most popular EVM wallet available today. I was a fan but Rabby wallet won me over. With Rabby, Users can also see decoded output of the hex value/hash being signed which is a plus for Security.   :)

I am not sure, but TrustWallet seems to claim to be an open-source, non-custodial wallet that supports multiple cryptocurrencies. I am not aware of these two wallets you mentioned in the post. Currently, I don't feel safe with wallet software when the question is storing large amounts. I think we have to practice using a hardware wallet to store our funds. Otherwise, keep using an existing trusted non-custodial wallet instead of choosing a new one that we are unaware of. Hardware wallets don't cost too much lately since a lot of companies have launched hardware wallets.

Trust wallet was open source but after Binance acquired it in 2018 they became closed source. You can even find the details on Github which never updated for very long time. So if you are not aware of it then please be cautious and google results says its open source which is kind of misleading information available in their site.

Unstoppable wallet is even recommended by theymos and crypto.com is also not really new which is here for years and being an open source you no need to trust them. HW are good for storing big amounts but for an average joe it may not be really necessary and instead of trusting a closed source app with your money its good to prefer an open sourced.


Another issue with HW wallets in recent days is the privacy of users is in question especially Ledger gave false information about being open source and their ledger live application has the capability of extracting recovery seeds of users which isn't looking good.

Mycelium is open source wallet.

https://walletscrutiny.com/?platform=allPlatforms&page=0&query-string=Mycelium


IIRC, they were also use some misleading wording in their website which make regular user thought it is an open source application.

In regarding the reason why they move to closed source is becaesu they claim, their app is cloned for nefarious purpose.

Worth to note that wallets being open source doesn’t automatically imply it safe, trustable, and secure.

Being open source does not necessarily mean that you are safe, as you must ensure that the code that you install on your device is the same as the open source code and that there are enough reviews to say that this open source code is safe.
You can verify that you are installing the same code by verifying the signature, but there must be enough reviews, otherwise there is no difference between closed source and open source code.

A while ago, there was a scammer who put open source code for a wallet, but when you installed the wallet, the code was completely different and he stole the money.
I have never heard of https://github.com/crypto-com/chain-desktop-wallet and I don't want to know if it is safe, but I created a topic about user experiences regarding Unstoppable wallet and this is the link https://bitcointalk.org/index.php?topic=5436273.0

Metamask allows custom networks, so you can add any network available even if it's not there by default, easiest way to do this is with chainlist [1]. Recently, they have also added snaps feature to allow user to interact with different non-evm networks which are not supported natively (solana, cosmos, tezos, polkadot, etc), this feature is somewhat like add-on as far as I understand.

There is metamask android app too.

I posted those two wallets simply because I saw some of the veterans who are active in the technical discussion board suggested to the users so I think it is safe but as I said this thread can serve us to find all the available options and choose the best for the users according to their requirements.

My first time hearing about this wallet. it might be worth checking out.

Mycelium is open source, though its developers started using it to advertise scams, so I don't like it.

Metamask has a standalone desktop wallet software? I only know of the browser extensions and mobile apps

This needed to be updated from time to time or have a regular discussion to bring this topic to the top. Unstoppable wallet should be at the top of any search engine but for some reason it's the trash and centralized app called f***wallet that noobs tend to end up using.

Those ads are the reason I uninstalled this wallet.

There are many wallets in the market and many of them are open source wallet like MetaMask. I will try to use this wallet and will share my experience after using. At this time this is new and no one knows how much it is reliable.
By thew way thanks for sharing this wallet. I have installed it and will try to use it.

That is also a valid concern about open-source projects. Regular users can't make a judgment on their own. They cannot understand the code. So the whole idea of open source must mean it is safe is a misconception.

The last point for the end user besides ensuring the reproducibility of the program is also the project must be massively used by the users, and that might come from consistent development with a good ecosystem. So the project gathers and attracts technical people to work toward the developments. More eyes should be able to detect in case if there is something shady or wrong within the code. So the trust within the community itself is already built.

I'm pretty sure he means the browser extension instead of an installed desktop software.

I forgot that they do advertise a scam. This should also be noted that some open-source project teams might be prone to such bad ethics.

It's not entirely new, they have been here for a while also if you have participated or read the discussions related to those wallets,s especially the Unstoppable wallet is the best alternative available to trust wallet and other multi-crypto wallets and has many users who also expressed their feedbacks about the wallet in the wallets section.

Open source, non-custodial wallets are great. But they're still considered "software wallets". You know how risky it is to store large amounts of crypto in such a wallet. If these apps had hardware wallet support, then it would've been another story.

I'd prefer to use an open source hardware wallet with an open source software wallet for complete peace of mind. I don't think such thing exists for mobile OSes such as Android or iOS, but nothing's stopping developers from making it happen in the future. If you're storing small amounts of crypto, then a software wallet would be more than enough to fulfill your needs. Lets hope we get more choices for true financial freedom. :)

Open source wallets are better in terms of security and there are few open source wallets that support most of the devices and OS. They are good for regular uses like if someone has to use his wallet more frequently to use any dapps then these wallets are the best choices but hardware wallets can provide the best security for your funds. If you are a long term holder then one of the hardware wallets can be your best friend to keep your funds secure.

I would like to give my opinion regarding this wallet, which I have used for several months since the beginning of this year, and I still keep it on my device for quick uses when I am away from the office, since I only have the Electrum Bitcoin wallet on my phone.
I can say that my experience with it was not bad and is quite satisfactory, since using the wallet is very easy and any user, whether a beginner or an experienced one, can use it without facing complications of any kind. The only important thing is to be able to distinguish between different networks because this is what makes it a bit difficult for multi-currency wallets.
The only criticism is that I was not able to set the fee when I wanted to send. The fees are determined automatically from the wallet, and I do not know the source of those settings, that is, how the amount of those fees is determined according to any data.

I have used unstoppable wallet a couple of times on my mobile device. I was previously using Electrum wallet and after the last update I have now completely stopped using it. I generally  prefer using its desktop version as it is far better than the mobile version. Unstoppable is not completely a Bitcoin wallet you can add other cryptocurrency to it.

You can use kiwi/lemur/mises browsers to use metamask extension on android or if you are on iOS you can orion browser (I don't have iOS so idk how well it works there), on android at least it works good as desktop, just pop-ups happen on new tab instead of same screen pop-up as on desktop.

Alternative option is Alpha wallet, available on both android/ios, open source, repos can be found on website [1]. Evm chains only.

If you don't want to "break the bank", open source software wallets would be your best bet to secure small to medium amounts of crypto. Just make sure to never disclose your private keys and/or seeds, and you'll be good to go. A good thing about open source wallets is that vulnerabilities are easy to discover and patch accordingly. It makes them stronger and resilient over time. If only the aforementioned open source wallets had hardware wallet support, we would be able to achieve true peace of mind. Your crypto funds would be virtually impenetrable.

Of course, there's nothing in this world that's 100% secure. You'd need to follow the necessary security precautions to avoid becoming a victim of scams and/or theft. It seems to me that Unstoppable Wallet is the best open source crypto wallet in the industry. Lets hope it stays that way forever. ;)

op You may be used to using Metamask wallet so maybe you are telling others to use Metamask wallet but this wallet has some issues. I myself used Metamask wallet but Metamask wallet has many network problems. I stopped using it due to network issues. If there was no network problem then I would have continued to use it. Since I am suffering from this problem I said Metamask wallet network problem now those of you who want to use Metamask wallet can definitely do so

If you are having network issues, that should be an issue you need to rectify with your network provider and not an issue with Metamask, unless there are other things that make you dislike it, like other issues discovered that make you not want to use them again.
 
I have used it several times, but I don't remember having any network issues. I just don't use it more often as it's stressful sometimes for me to login to my computer and have to access the extension, and the fact that I don't hold much of an altcoin even makes it worse for me to visit it this period; unless I have a need for it, I don't open it. Secondly, it's an online wallet, so I wouldn't want to get it linked to a site I don't know, so it's safe being closed all the time until I have a need for it.

No he isn't the OP. The real OP here is jrrsparkles. I have also tried using Metamask for both of my computer and mobile in the past and like you, I have also experienced some issues with it for both systems. By the way what network issues do you mean? Is it about your carrier?

Well, it could also be because your connection was slow. If it is, then don't put all the blame in Metamask but if the network you mean is related to crypto, then maybe you are also correct that the problem was on their side. How long did you stop using the wallet anyway? If it's long time ago, then why not try them once again? Give them a chance and see if those issues are already sorted out.

I am not sure what kind of network problems you are mentioning but it is one of the wallet for altcoins with fewer bugs and probably the oldest one we have as open-sourced. But I am not using it anymore either cause I am not interested in the tokens anymore and it becomes a dead weight for someone's wallet and even if you want to burn it still you need to pay gas fee.

What exactly network issue you talk about? If it's about loading bar going on and on, then get the different rpc from whatever is default on from site like chainlist [1] for the chain you are having network issue and it'll be solved.

Metamask or any other wallet is just a tool to interact with chains, there can be no issue with MM itself technically.

Thanks for the name, I didn't know the existence of this wallet, and upon checking their website and GitHub page it seems they are pretty good but the only thing is only supports Ethereum and it would have got more user base if the wallet supports multiple chains because those olden days changed now due to the existence of BNB and other chains.

They support all evm networks, if it's not available in wallet by default you can add it manually by getting info from sites like chainlist [1]. Popular chains such as bnb, op, polygon, etc are there already, you just have to enable them from settings.
