[LIST] Multicoin Open Source Wallets

[dkbit98]

There are several good open source Bitcoin wallets available for both desktop and mobile devices, but situation is not that great for people who want to use one wallet for multiple coins.
Many people used Coinomi wallet for years but they changed the source code and developers are not maintaining it anymore.

I decided to start working on creating a list of Multicoin Wallets that are open source or with similar source available license.
There won't be any rating in my list, but I will write my short review for most of them with pros and cons.

Any wallet in this list must support Bitcoin mainnet BTC along with other additional coins!

Desktop wallets::

• OneKey desktop wallet
• Stack desktop wallet ^{(coin control, tor)}

• Komodo desktop wallet
• Uniblow desktop wallet
• Cake wallet (MAC) ^{(coin control, tor)}

• Coin wallet

Mobile Wallets:

• OneKey mobile wallet
• Stack mobile wallet ^{(coin control, tor)}

• Komodo mobile wallet
• Cake mobile wallet  ^{(coin control, tor)}

• Unstoppable mobile wallet
• Mycelium mobile wallet
• Coin wallet mobile
• AirGap mobile wallet

Wallets for Bitcoin and Liquid assets L-USDT and L-BTC:

• Aqua wallet
• Green wallet
• Specter wallet
• Jade HW
• Ledger HW

Note that safest option for this purpose is to use hardware wallets like Trezor, Bitbox, Keystone, Onekey, Satochip, etc.


This topic is work in progress, and it is opened for discussion.

Every contribution is appreciated so please post your suggestion for other open source wallets.

I suggest you also add a source link for every wallet; for instance I cannot find the source code for Aqua wallet.

As for open-source, multi-coin hardware wallets, I'd add:
Keystone (firmware, application)
BitBox02 (firmware, application)

That is because the wallet isn't open source (for now[1] apparently). As a curiosity, this wallet was originally launched by Blockstream in 2020[2] but when Samson Mow - the author of the tweet[1] and ex executive of Blockstream- left the company in 2022, he managed to raise funds to create a new company called JAN3[2]. Probably he used some of the funding money to buy AQUA wallet? Apparently a user in Stack News sent JAN3 an e-mail inquiring about the release of the code[3] and they told that it would happen next week. I guess we will have to wait and see.

PS: It seems to exist an open source wallet called Aqua Wallet (instead of AQUA wallet)[4]. Perhaps dkbit98 was talking about this one? Probably it wasn't the case considering that this one is for ETH ...

Side note but important. It's not just open Open Source but Open Source and Current.

Even now there are a lot of projects that are open source or at least close to it but what you can find on github and other places is weeks / months behind what you will get when you download from the app store / play store.

Back in the beginning even coinomi had SOME current code available. It just didn't last. So good today does not mean good tomorrow. Be alert.

It's a very interesting topic thanks you for the idea but it would be interesting to know which wallets of the list support Web3 connection to DApps too. And which main cryptos(not all ofc) they are offering.
As mobile wallet, there is Alphawallet, which is open source but it only supports EVM blockchains.

This is a good list you have bring Op. And yes as you said,  many people want to use one wallet which have different sections that can accommodate more coins and the only wallet I noticed that function was Trustwallet but the interface of Trustwallet is not what people people need. We need a open source wallet like Electrum. But we have not seen Open Source Wallet that has multiple Coins inside. 

Thanks for the list we will check all to choose nthe one that favourable to us.

The only wallets I've tried are Cake wallet, Mycelium, and Unstoppable. I haven't heard of the rest, so this would be a good opportunity to try some out.

Wallets for Bitcoin and Liquid assets L-USDT and L-BTC:

Aren't L-USDT and L-BTC the same as wBTC, in which Bitcoin is locked in exchange for tokens and therefore we consider it an altcoin? It is not always possible to guarantee 1:1 or am I wrong about it, I have no experience with Liquid assets

[dkbit98]

Sure, I will add it at later stages.
This is just something to get me started, since I planned to created this topic for a while,
however I am not going to add hardware wallets in this list (except if some of them adds support for L-BTC and liquid network).

That is because the wallet isn't open source (for now[1] apparently).

Correct.
They are cleaning the code and working on releasing it as open source with some improvements.

Side note but important. It's not just open Open Source but Open Source and Current.

Don't know what ''Current'' is.
I am adding open source and source available wallets in this list.
It is up to each user to check if wallet code is reproducible or not.
Aqua walet is bonus category since it's not technically a multicoin wallet

As mobile wallet, there is Alphawallet, which is open source but it only supports EVM blockchains.

This does not my cup of tea, since it doesn't support Bitcoin BTC.

Aren't L-USDT and L-BTC the same as wBTC, in which Bitcoin is locked in exchange for tokens and therefore we consider it an altcoin? It is not always possible to guarantee 1:1 or am I wrong about it, I have no experience with Liquid assets

No they are not, since you don't need any shitcoins for sending L-BTC and L-USDT, and everything is backed by bitcoin.

IMO current is what is in github (or wherever) can be compiled to be what is in the playstore / downloads / whatever.
As I pointed out for a while you could take what coinomi had online compile it and you got the same binary download that they were giving giving you.
At some time that stopped.

Too many people, myself included, may check once or twice that what they are giving me is what they say it is and then never check again.

Good point; I didn't notice such thing since I usually download releases directly from GitHub. If you don't do that, there's the additional risk that the binary doesn't match the source code, even if the version number matches.


Aqua source code was published today:

I don't know much about wallets, both desktop and mobile versions.

The open source desktop version of the wallet that I use is only Electrum and plan to try Bitcoin Core by completing the full synchronization (Sync) even though I know it will take several days to complete 100% according to friends who have completed it.
There is Wasabi which is familiar to me but I have never tried it.
This wallet is not a multicoin wallet.

The mobile version of the wallet that I have used is BlueWallet but it is not a multicoin wallet. From the list in the OP, only unstoppable is the one I still use on my mobile to store several assets, but in my unstoppable wallet I don't store Bitcoin.

Here, I don't have any suggestions as to what I want, I just want this topic to be active so that I can find out more about open source multicoin wallets by reading all the discussions that come in.
Learning from greater people can have a great effect on my knowledge.
