FAQ
FAQ
A quick overview of how Qvard handles payments, integration and merchant operations.
What is Qvard?
Qvard is a custodial crypto payment gateway for businesses that need hosted checkout, invoices, API payments and merchant balances.
Which assets are supported?
You can accept USDT, USDC, BTC, LTC, TRX, BNB and ETH. USDT is available on several networks, so customers can pay through the route they already use. TON and USDT on TON are coming soon.
Is it good for developers?
Yes. The integration is built around creating a payment, redirecting the customer to redirectUrl and receiving a final webhook status, so orders in your system update automatically.
Can I customize checkout?
Yes. You can set the shop name, logo, button color and localized texts so the payment page feels like part of your product. Custom return URLs (successUrl/failUrl) are coming soon.
What do I need to get started?
Create a merchant account and complete business verification. After testing a demo invoice, connect hosted checkout or the API and start accepting real payments.
How do withdrawals work?
Funds are tracked in merchant balances separated by asset and network. You can withdraw manually or set up withdrawal rules for automatic payouts.
