In Third Wave of Bitcoin Grants there was a good news for Krux wallet, that is one of the ten projects who received grants from OpenSats.
Other Bitcoin projects that received grants are Clams, Fully Noded, Validating Lightning Signer, Fedimint Lightning Gateway, Pickhardt Payments plugin for Core-Lightning, BitBanana, Crack the Orange, Bitcoin Core App and Vexl.
Krux is a free and open-source firmware that enables anyone to build their own Bitcoin signing device via off-the-shelf parts. It runs on Kendryte K210 Risk-V-based devices such as the M5StickV and Maix Amigo, converting them into air-gapped devices that can sign transactions for single and multisig wallets. Krux can also sign messages and has easy-to-use tools to help with the creation and loading of wallet backups.
Users can choose to buy a ready-to-use device—where all they need is to flash the firmware—or make a DIY version themselves. Krux can also run, mainly for educational purposes, on PCs and Android devices.
