Technology

Non-custodial by design.

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.

How settlement works

Money moves on-chain, peer to peer. U.CASH is the routing and checkout layer, not a custodian.

Direct to your wallets

Buyers pay into addresses you control: xpubs and per-chain wallets. Funds never pass through a U.CASH custody account.

Multi-chain routing

One checkout accepts 30+ blockchains and custom tokens across 22 networks. The customer picks the asset; you get paid.

Cards via your Stripe

Fiat card payments run through your own Stripe account. No middleman holds the money.

Signed webhooks

Every payment event is delivered to your server with a signed webhook so you can fulfill with confidence.

Per-coin confirmations

Configurable confirmation policies per chain and per coin, so you balance speed against finality.

Web3-name payouts

Resolve ENS, Unstoppable, and FIO names to addresses so payouts can go to a human-readable name.

Security model

No pooled custody

Because we do not hold funds, there is no central honeypot to attack. Each merchant's risk is isolated to their own wallets.

You keep the keys

Wallet keys and Stripe keys stay with you. U.CASH stores only what is needed to route and notify.

Signed, replay-safe events

Webhooks are signed and guarded against replay, so fulfillment triggers only on verified payments.

Open and auditable

REST APIs, SDKs, and transparent fee models. Settlement is verifiable on-chain by anyone.

Build on the rails

Open APIs and SDKs

Integrate payments, build invoicing, or put an AI agent on HTTP-402. REST API, signed webhooks, and JS / Python SDKs.
