"cashu is for custodial bitcoin wallets" – yes but it's much more than that.
cashu is so lightweight that some web services run their own mint instead of managing an accounting ledger with user balances and transactions.
cashu allows your users to top up a balance and use their credit to pay for your service. it's perfect for closed-loop systems where funds flow in a single direction: from your customer to you.
no users, no tracking, and incredible privacy out of the box.
it's already happening.
