## Why Stable Genius?

<AccordionGroup>
  <Accordion title="Two API calls. That's the integration.">
    Create a payment intent, receive a webhook when it confirms. Your system never touches wallets, blockchains, or bridges. We handle all of it.

  <Accordion title="Non-custodial by design">
    Merchant funds settle to on-chain smart contracts they control. Every transaction is verifiable on-chain. We never hold merchant funds.
  </Accordion>

  <Accordion title="Stablecoin in, dollars out">
    Customer pays with USDC. Merchant receives USD via ACH to their bank account. Automatic weekly settlements or manual cash-out anytime.

## Who Is This For?

**Terminal & POS integrators** — Add stablecoin payments to your existing hardware. We provide the payment address and QR payload; you render it on your screen.

**App developers** — Accept stablecoin payments in your mobile or web application. Same API, same webhooks — just render the QR in your UI instead of on a physical terminal.

**Platform operators** — Enable your merchants to accept stablecoins. Onboard merchants through our dashboard today, or programmatically via API when our merchant onboarding endpoints launch.
