Connect Your Bleskomat ATM to CoinOS via Bleskomat Platform

Coinos is an easy-to-use and quick way to get up and running on Lightning in seconds. Their friendly user-interface is a breeze to navigate and best of all you can use coinos completely anonymously – now that’s cool.

For more information please visit these two pages.

Setup coinos

Setting up coinos is super easy and fast. The first step is to navigate to You can either create your own username by clicking on “Register An Account”. Or you can choose “Use Anonymously” and a random username and password will be generated for you. If you choose the anonymous method, you should immediately change the password to something unique and secure. Whichever method you choose we recommend to enable a PIN, two-factor authentication (2FA), or both via the Setup Account page.

That’s it! You now have a custodial Lightning wallet setup and ready to use. Custodial means you do not control of the private keys or channels, which allows for ease of use but comes with trade-offs that you can research and be aware of. For storing small amounts of bitcoin this should be OK but it is important to understand the risks.
