CoinOS is an open source bitcoin web wallet, point of sale, ecommerce marketplace and exchange platform. Development started in Vancouver in September 2012 as a way to provide local merchants with a convenient way to accept bitcoin payments.

The feature set has grown over the years to accomodate a wide variety of use cases with the goal of making it as easy as possible for anyone to get started using Bitcoin quickly, cheaply, and securely.

Anyone can download the source code and host their own instance of the platform backed by their own bitcoin, liquid or lightning nodes, or reach out and we'll gladly set this up for you.

Intra-account transfers between custodial wallets of different users on our server are completely free, instant, and unlimited.
