StablePay

StablePay is the PhonePe for global payments — enabling instant, low-cost cross-border transfers using stablecoins with zero crypto complexity.

Comment

Inspiration

Global payments system broken hai — especially India ke freelancers aur NRIs ke liye. Har transaction me high fees (5–6%), delays (2–5 din), aur hidden charges hote hain.

Real users se baat karne par pata chala:

₹3,000–₹4,000 loss per payment e-FIRA jaise compliance ka headache No transparency in exchange rates 👉 THATS WHY THI IDEA EXPLODE IN MY MIND : If UPI can simplify payments in India, there should be a similar system for global payments as well

What it does

StablePay ek cross-border payment app hai jo:

🌍 Instant global transfers (4 seconds) 💸 Fees <0.3% (banks se 20x cheaper) 📱 UPI-like handle system (@username) 🤖 AI-based rate optimization 📄 Auto invoice + e-FIRA generation

👉 IN Simple words : Users can send/receive global payments without any crypto knowledge – a similar experience to UPI.

How we built it

📱 Frontend: Flutter (Android + iOS + Web) 🔗 Blockchain: Stellar (fast & ultra-low fees) 🪙 Stablecoins: USDC / USDT 🗄️ Backend: Supabase (Auth + DB) 📊 APIs: CoinGecko (live rates), Circle (USDC) 💸 INR Off-ramp: Razorpay (planned)

👉The MVP was built using completely free tools. 👉 Real transactions are running successfully on the testnet.

Challenges we ran into

🧾 Regulatory complexity (RBI, FEMA, e-FIRA) 🧠 Users ko crypto UNDERSTANDING (trust issue) 💱 Stablecoin → INR conversion flow design 🔐DEMANDING Non-custodial wallet security 🌐 Cross-border compliance 👉 Biggest challenge: Handling Trust and Regulation Over Tech

Accomplishments that we're proud of

✅ Working MVP built (zero funding) ✅ 15+ freelancer interviews → problem validated ✅ Real blockchain transactions executed ✅ Full PRD + product roadmap ready ✅ Unique features: -UPI-like handles -Auto e-FIRA -WhatsApp-native payments -AI rate alerts

What we learned

💡 Problem validation is more important than coding 👥 Real users se baat karna = goldmine insights ⚖️ Fintech = 50% tech + 50% compliance 🤖With these tools, even a solo founder can build a powerful product. 🚀 Simplicity (UPI-style UX) is the biggest differentiator

What's next for StablePay

🚀 Short Term (0–3 months) -Mainnet launch -500+ early users -Zero-fee onboarding campaign 🌍 Mid Term (3–6 months) -NRI corridors (UAE, USA, UK, Singapore) -5,000 users + $2M monthly volume 📈 Long Term (6–12 months) -B2B API (Upwork/Fiverr payouts) -RBI Sandbox integration -e-Rupee support 50K+ users + $20M monthly volume

*StablePay is building the financial layer for India’s global workforce — making cross-border payments as simple as sending a UPI.
