Hello.

We have prepared the HMT source code https://github.com/hatchpay/hatch-masternode-tool with built-in support for hardware wallets Trezor, Ledger and KeepKey. Now only the manufacturer Trezor supports HATCH. We have done everything in our power to integrate the HATCH into Ledger and KeepKey, but is not currently supported by manufacturers. Those who wish can start testing.
