Hardware Solution for Coiny Safety
Programming API

The following documentation contains the programming API which allows initial development of crypto currency applications.


We are looking for interested developers to help us build applications while we are busy developing and finalizing our CoinyCard. Here you can download and alpha version of our API that allows querying a CoinyCard.

The API allows installing 64 private keys onto the CoinyCard, as well as retrieving them with a PIN. We plan on allowing private key operations in the near future with a firmware update.
