Add a Fiber wallet in a few lines.

A different app — Acme Checkout — integrates Clasp with a provider, a button, and one hook. Everything on this page is driven by @clasp/react talking to the same policy engine.

Integration🔒 relay-blind

import {
  ClaspProvider,
  ConnectFiberWalletButton,
  useClaspSession,
} from "@clasp/react";

<ClaspProvider config={{
  serverUrl, origin, app: { name: "Acme Checkout" },
  permissions: ["payments:request"], asset: "CKB",
  maxSinglePayment: "100000000",
  maxSessionSpend: "300000000",
  sealed: true, // encrypt payloads end-to-end
}}>
  <Checkout />
</ClaspProvider>

// inside <Checkout/>:
const { pay, capabilities } = useClaspSession();

<ConnectFiberWalletButton />
const r = await pay({ invoice, amount: "100000000" });
if (r.ok && r.receipt.verified) unlock();

With sealed: true, each payment is encrypted end-to-end to the wallet core (X25519 + XChaCha20-Poly1305). The standalone relay forwards ciphertext it can't read.

Connect on the left — the hook exposes the session, its capabilities, and pay().
