Theya
Mobile-first multisig self-custody — set up a 2-of-3 vault with your phone, a key partner and a backup, no desktop required.
Theya makes multisig self-custody work from your phone: a 2-of-3 vault set up with your device, a key partner and a backup, without needing a desktop or hardware-wallet ritual to get started. It aims to make the security of multisig approachable for mobile-first users.
The appeal is getting past single-key custody without the friction that usually scares people off multisig. Convenience on mobile is the selling point; purists will still prefer air-gapped hardware in the mix, and you should understand where each of the three keys lives before trusting a vault with real size.
