Direct to your wallets
Buyers pay into addresses you control: xpubs and per-chain wallets. Funds never pass through a U.CASH custody account.
U.CASH is open money infrastructure: payment rails that route across 30+ blockchains and settle directly to wallets you control. We never hold funds or keys. Here is how the architecture works.
Money moves on-chain, peer to peer. U.CASH is the routing and checkout layer, not a custodian.
Buyers pay into addresses you control: xpubs and per-chain wallets. Funds never pass through a U.CASH custody account.
One checkout accepts 30+ blockchains and custom tokens across 22 networks. The customer picks the asset; you get paid.
Fiat card payments run through your own Stripe account. No middleman holds the money.
Every payment event is delivered to your server with a signed webhook so you can fulfill with confidence.
Configurable confirmation policies per chain and per coin, so you balance speed against finality.
Resolve ENS, Unstoppable, and FIO names to addresses so payouts can go to a human-readable name.
Because we do not hold funds, there is no central honeypot to attack. Each merchant's risk is isolated to their own wallets.
Wallet keys and Stripe keys stay with you. U.CASH stores only what is needed to route and notify.
Webhooks are signed and guarded against replay, so fulfillment triggers only on verified payments.
REST APIs, SDKs, and transparent fee models. Settlement is verifiable on-chain by anyone.
Integrate payments, build invoicing, or put an AI agent on HTTP-402. REST API, signed webhooks, and JS / Python SDKs.
