Icarus Wings

icaruswings@trikey.app trikey.app

Building Trikey: an open source bitcoin wallet where you hold all three keys. Your phone, a hardware wallet and a guardian on your own home server. Any two move your money.

Phone and guardian talk over end-to-end encrypted nostr messages: no open ports, no company in the middle.

Pre-alpha, not audited: testnet and signet for now. MIT, built in public.
