The Challenge

An Indian startup needed a UPI-first digital wallet with bill payments, peer-to-peer transfers, and merchant QR payments — competing directly with PhonePe and GPay in a saturated market where speed and trust are everything.

The Solution

Ubikon built a cross-platform app with React Native, integrated Razorpay for seamless UPI transactions, built a merchant QR scanner with instant settlement, and added a rewards engine with a referral system that drove organic growth.

How We Built It

1

Market Analysis

UPI ecosystem mapping, competitor feature audit, regulatory compliance review with RBI guidelines.

2

Architecture

Event-driven backend with Node.js, Redis caching for transaction speed, PostgreSQL ledger design.

3

Core Wallet

Razorpay UPI integration, P2P transfers, bill payment aggregator, merchant QR scanner.

4

Rewards Engine

Cashback rules engine, referral tracking system, gamified streak rewards for daily usage.

5

Launch & Scale

Beta with 500 users, load testing for 10K TPS, Play Store launch with influencer campaign.

"Ubikon understood the Indian payments landscape inside out. They shipped a production-ready wallet in 16 weeks that our users actually prefer over the big players for daily transactions."
