The world's first decentralized marketplace for converting prepaid airtime PINs into cryptocurrency. No KYC. No bank account. Just your phone.
Traditional exchanges require bank linking. Over 1.7 billion adults worldwide don't have access to formal banking.
KYC requirements exclude billions. Many lack the documentation that centralized platforms demand.
Remote regions have spotty connectivity. Most crypto apps fail the moment you lose signal.
But here's what they do have: prepaid airtime—available at every corner shop, purchased with cash, no questions asked.
Four steps to financial freedom. No middlemen. No custodians.
Walk into any local shop and purchase a prepaid airtime scratch card with cash. No ID required.
Open the app, scan the PIN, and broadcast your offer. Works even offline via Bluetooth.
A smart contract locks both assets. The trade completes only when both parties are satisfied.
Receive USDC, cUSD, or other tokens directly to your hardware-secured wallet. You own your keys.
Choose your role to see how the transaction works from your perspective.
