Thanks ;) It is open-sourced, of course, the code is available here: hiveledger
There is also a set of other projects that might be helpful to understanding Ledger APIs etc:
- app-hive - low-level ledger application, there is also the documentation of APDUs and app commands in doc directory
- ledger-app-hive - Typescript library to communicate with Hive ledger app
- hive-ledger-cli - Simple CLI to communicate with Hive Ledger App
🙏
