The application implements the APDU messages interface and UI to communicate with the Skycoin companion application. It covers the following functionalities:

• Retrieve a public key and display Skycoin address given a BIP44 path
• Retrieve a skycoin address
• Retrieve a signed public key
• Sign a basic Skycoin transaction given a BIP44 path
• Get application info(version)

Note: BIP32 was replaced by BIP44. One of the reasons for it was to register skycoin here.
