A 2 of 3 bitcoin wallet with no words on its screens. Three dots for three keys. One arrow to receive, one to send. Its name is Trivium.
Three keys
Each SeedSigner shows its public key as a QR code. Tap a dot and scan it.
One backup
After the third key, Trivium shows the descriptor. Save it. A SeedSigner loads it to check the change.
Receive
↓ shows the next address. A used address never comes back.
Send
↑ scans an address. Type the amount in sats. Two signers approve on their own screens, and each one lights its dot.
How it works
- Bitcoin Core finds the coins and builds the payment. Trivium only moves QR codes.
- No account and no server wallet. The link is the wallet.
- Under 200 lines of code.
Why Trivium
Latin for three roads, and the root of the word trivial. Also a cipher from KU Leuven.
