## How it works <a href="#how-it-works" id="how-it-works"></a>

1. Create a KYC-verified recipient (individual or business).
2. Generate a quote with real-time exchange rates.
3. Create a transfer (off-ramp or on-ramp) by locking the quote.
4. User deposits crypto or fiat to the provided address or account.
5. Receive webhook notifications as the transfer progresses through its lifecycle.
6. Funds are delivered to the destination.
