You choose an amount and get a link. You share that link on WhatsApp, just like you'd share anything else. That's the transfer — no forms, no account numbers.
Your recipient taps the link and sees the money right away, before creating anything. Then they claim it in their browser with their face or a password they choose.
The exact amount arrives, held in dollars. Receiving is free. If nobody claims the link within 7 days, the money comes back to you.
