A curated index of the U.CASH open money infrastructure ecosystem: 120+ open-source plugins, SDKs, bots, and integrations for accepting crypto + cards anywhere. Non-custodial by design.
Every U.CASH Pay plugin shares one integration model: create a checkout, redirect the buyer to pay.u.cash, verify the HMAC-signed settlement webhook, and mark the order paid. Funds never touch a custodian; they settle direct to the merchant's own wallet addresses. One publishable Cloud token per store.
