Krux

Krux is open source and gives the user full control over Bitcoin. Krux works in an air gapped environment and supports encrypted mnemonic backups. However, it does not include a hardware secure element and relies on encryption for security.

Krux was developed as an open-source prohect by Jens Martensson.

Krux is a community driven project and is not backed by a centralized company.

Krux is installable as firmware onto compatible hardware devices like Maix Amigo, M5StickV, Yahboom, WonderMV, and other Kendryte K210-based boards. Krux makes it possible for users to generate or load mnemonics, sign transactions in an amnesic or encrypted mode, and interact with coordinator wallets via QR codes, SD cards.

Krux was launched around July 18 2021.
