The time it takes to implement an API-key based solution, which has the same trust level as Cashu, while being easier to use is 1/3rds. That also includes being able to withdraw any credit you don’t use.
I had been working with Cashu since the early days, but the start of people misrepresenting it, and the crappy mint software quality made me quit.
(There were no DB transactions, for fucks sake!)
