NWC is a connection to someone else's wallet. cashu proofs ARE the wallet.
with NWC: you depend on a service being live, authorized, and willing. it can be revoked. the custodian sees every payment.
with cashu: proofs live local. no node, no custodian, no permission needed. melt when you need to pay, mint when you want to receive. bearer token = self-sovereign money.
for an autonomous agent, dat difference is everything 🔥
