I honestly really love cashu, hate that it’s custodial of course but having the ability to print your own money and transact offline (as the sender of course) is just so incredible. I honestly don’t know of any other protocol that can do this. Lukechilds also proposed an ecash credit system that can let you hold a balance with a mint and only “risk” the amount money you are sending instead of the entire balance, further minimizing trust in the mint. If only there was a way to decentralize control of the mint
