opentensor / ledger-bittensor

Trying to implement a ledger app for Bittensor

Ledger Bittensor App

---

Forked from Zondax/ledger-picasso

---

This project contains the Bittensor app (https://www.bittensor.com/) for Ledger Nano S and X.
Supporting transfers and staking after the Finney fork.

• Ledger Nano S/X BOLOS app
• Specs / Documentation
• C++ unit tests
• Zemu tests

For more information: How to build

ATTENTION

Please:

• Do not use in production
• Do not use a Ledger device with funds for development purposes.
• Have a separate and marked device that is used ONLY for development and testing
