**Send Money. Pay Bills. Buy Airtime. With Your Phone Number.**

## 🚀 **What is Celo Naija?**
**Celo Naija** is a **mobile-first, Nigeria-first remittance app** that empowers **anyone with a phone** to send money, pay bills, and buy airtime — **no bank account or seed phrase required**.
Powered by **Celo L2**, it transforms your phone number into a secure wallet via **SocialConnect**, uses **cNGN** (Naira-pegged stablecoin) for instant transfers, and includes **USSD fallback (*888#)** for feature phones like Nokia or Tecno. It's designed for the 40M+ unbanked Nigerians, slashing fees from 7–12% (Western Union) to **<1%** while feeling as simple as WhatsApp.
**Live Demo:** celo-naija.vercel.app (Sepolia testnet)
