Bitcoin Armory

Bitcoin Armory is an offline signing wallet for air-gapped cold storage. It generates keys, derives addresses, and signs transactions on a device that never connects to the internet. Data moves to and from your online wallet through animated QR codes or via offline File transfer. The app supports Native SegWit, Taproot, and Silent Payment addresses, with optional dice-roll entropy for key generation. Face ID, password encryption, and coin control included.
