About open source cryptocurrency wallets

Transparency and openness are also key aspects of blockchain technology and cryptocurrencies. Bitcoin and other blockchains like Ethereum are open-source initiatives (Bitcoin under MIT license and Ethereum under GPL license).

This means others can access the source code for them. They can create their own versions from the code and create new Ethereum/Bitcoin forks.

Open-source softwares is in some ways perfectly aligned with this space, therefore there is also a much greater interest in products and services that operate in this space to also be open-source.

And one thing I have in mind specifically are open-source cryptocurrency wallets.

With cryptocurrency wallets we store and integrate with our cryptocurrencies, and in good faith that this software and application is reliable and safe to use.

And what better way to prove that than by making your wallet application and software fully open source. So that others can inspect and audit the code at any time.

If you value openness, transparency and decentralisation and if you own cryptocurrencies like BTC, ETH, LTC, etc then I wanted to make you aware of these 9 good cryptocurrency wallets that are open source.

What is open source?

As the name suggests it means that the code in which the application is built on is licensed in such a way that it is open for others to read and modify.

There are some different types of licenses available which might suit you better depending on the application/software you are developing.

We have named the MIT license, there are also GNU, Apache and others (see them all here).

To learn even more about how open source works and the different licenses we recommend you to check out https://opensource.guide/legal/ and https://opensource.org/osd-annotated.

Conclusion

Which open-source cryptocurrency wallet should you go for?

Well, it depends on if you own more than Bitcoin today? Then you should look into one the multi-currency wallets.

If not, then either of the BTC-only wallets might appeal to you more?

What all these cryptocurrency wallets have in common is that they are all open-source crypto wallets. Some have support for multiple cryptocurrencies.

Others are Ethereum or Bitcoin-only wallets.

They are all very popular and used by millions of crypto investors around the world, so with that in mind I would myself trust all of them. But as always do your best to research and evaluate the wallets yourself.

Otherwise I hope this guide to the best crypto and Bitcoin open source wallets was useful.
