Calle launches BitNotes, a multi-mint Cashu wallet that prints ecash on paper
- —BitNotes prints ecash on paper with offline verification via mint signatures
- —Supports multiple mints, including 28MINT, with automated swaps between them
- —Integrates Lightning and Ark, plus a bridge for Rwandan Francs mobile money
- —Released under MIT and Apache licenses; no external security audits disclosed
Why it matters: The project tests offline payments for regions with thin banking infrastructure, but the lack of audits poses risks for early users.
