Cool!! Offline paying is such a nice functionality. I love Cashu, but to be fair, that was not entirely true last Monday. Internet was still working in several places, including mobile network (though arguably it was not very stable). So lightning and onchain could still be used. Even some card readers were functional. 🫂

In Portugal I lost mobile 2 hours after the blackout, but other places had it for longer. The info I have from the Telcos is that after 5 hours all mobile networks were down. Fixed lines seemed to be able to cope, but only in places with generators. Most places here started accepting only cash.
