Reproducible firmware. Verifiable by anyone.
Of the nearly 5,000 wallets independent non-profit
@WalletScrutiny has reviewed, only 123 passed every test.
OneKey Classic, Pro, Touch, Mini and Classic 1S are among them: all 10 tests passed, with firmware that was reproducible when tested.
That means anyone can build the firmware from public source code and get a hash that matches the official release.
Open source is more than published code. It's code you can check yourself.
