Accept crypto.
Settle in fiat.

Everything you need to accept crypto, built on rails you can trust.

Qint is engineered for production — state-machine driven, event-friendly, and audit-clean. Drop in the SDK, link the gateway, and start collecting payments in days, not quarters.

API-first payment intents

Create a payment intent, deliver instructions, and receive webhooks as the transaction moves from initiated through settled.

Hosted payment links

Beautiful Stripe-style checkout pages with wallet address, QR code, live status, and a countdown timer — no front-end required.

WooCommerce plugin

Native gateway plugin with merchant settings, hosted checkout redirect, and order status updates wired to webhooks.

Idempotency & safe retries

Every request is idempotent. Retry without fear — duplicate intents collapse and the audit trail stays clean.

Signed webhooks

HMAC-signed event delivery with replay protection. Listen for status changes and reconcile state automatically.

Immutable audit trail

Every state transition, retry, and webhook delivery is recorded — ready for reconciliation, disputes, and compliance.

Payment links your buyers actually want to pay on.

Share a link — or let the plugin redirect — and Qint hosts the checkout: the exact amount, a QR code, the wallet address, and live payment status. Branded to your shop, and just as good on a phone.

  • The rate is locked. A countdown holds the quote, so the amount your buyer sends is the amount you agreed on.
  • Status updates live. Your buyer watches confirmations arrive on the page — no “did it go through?” emails.
  • Send it anywhere. Email, invoice, chat, or straight from your store's checkout.

Built for developers. Boring in the best way.

Every payment is an explicit state machine, and every transition reaches your server as a signed, verifiable webhook. No polling, no guessing.

  1. Initiated

    Intent created — via API, payment link or the WooCommerce plugin.

  2. Pending

    Your buyer has the instructions; we watch the chain for the transfer.

  3. Confirmed

    Confirmations reached, amount verified on-chain.

  4. Settled

    Converted and paid out as fiat. Books closed.

Failed Expired

First-class terminal states, delivered over webhooks like every other transition — a payment is never stuck “somewhere on chain”.

Idempotent by design

Send a request twice, get one result. Duplicate intents collapse, and retries resolve to a single state transition.

Replayable deliveries

Webhooks are HMAC-signed and retried on failure — and every delivery is logged, so you can replay events your endpoint missed.

An audit log that can't be edited

Every state change, retry and delivery is recorded immutably — ready for reconciliation, disputes and your accountant.

Eleven currencies in. One line on your bank statement out.

Buyers pay from the wallet they already have — you receive francs, euros or dollars. USDT and USDC are accepted on Tron, Ethereum and Solana, so nobody has to move funds to a new network just to pay you.

  • KYB-verified merchants — onboarding runs through our regulated Swiss execution partner
  • Approval before money moves — payments unlock only once your account is cleared
  • Role-based access, so finance and developers each see exactly what they need
  • An immutable audit trail behind every payment and payout
  • Custody, compliance and fiat settlement on a licensed Swiss execution partner

Every asset settles to CHF, EUR or USD in your bank account. The full asset and network list lives in the developer docs.

Four steps from intent to settlement.

Idempotent, audited, and built around an event-driven core. No state guessing.

01

Create an intent

POST /v1/payment_intents with an amount, currency and an order reference. Qint returns an intent and a hosted checkout URL.

02

Buyer pays

We host the checkout: wallet address, QR, network, timer, and live status — all branded to your merchant.

03

Webhook fires

We watch the chain and ping your endpoint with signed events at every state transition.

04

Settle in fiat

Funds are converted and settled to fiat through our regulated execution partner. CSV exports and audit logs are ready for finance.

An API your engineers will actually like.

Stripe-shaped semantics, idempotency keys, signed webhooks, and SDKs for the languages you ship with. Drop-in for new builds and clean to integrate with legacy checkouts alike.

  • REST + JSON, OpenAPI spec, typed SDKs
  • HMAC-signed webhooks with replay protection
  • Idempotency on every mutating request
  • Sandbox keys & test wallets out of the box
Node.js · create_intent
import { QintClient } from "@qint/node";

const qint = new QintClient({ apiKey: process.env.QINT_API_KEY! });

// 1) Create a payment intent — price in fiat, the buyer pays in crypto
const intent = await qint.createIntent({
  amount: 124.0,
  currency: "CHF",
  title: "Order #4029",
  idempotencyKey: "order_4029",
  returnUrl: "https://shop.example.com/thanks",
});

// 2) Redirect your buyer to the hosted checkout
console.log(intent.checkoutUrl);

Ship on the platforms your merchants already use.

Qint is API-first, but you don't have to start there. Choose the integration that fits.
