"Imagine having to pay a landscaper for doing work and you have money on Cash App, Venmo, and PayPal, all of which you don't fully trust. However, you keep a small balance on each of them just in case you need to spend between friends or with certain vendors. The landscaping bill is a bit heftier than it typically is, so instead of sending funds from Cash App, Venmo, and PayPal to your bank account to then pay the landscaper instead, you combine part of the balance from each application to pay the singular invoice the landscaper has provided you. That is essentially what has just been launched on the Cashu protocol.
