Sell USDT for rupees in minutes
A peer-to-peer settlement platform for Indian traders: the rate locks the moment you commit, and payouts land by UPI, IMPS, NEFT or RTGS. Nadiron built the whole system, web and Android apps, backend and admin, and ran vulnerability tests on it before launch.

Approach
The moves that mattered
- Web app, Android app, backend and admin built from scratch
- Passkey sign-in and automated order routing
- Vulnerability tests run across the system before launch
Decisions
The trade-offs we chose
- Cut scope
- We trimmed the first version until it fit the time we had.
- Measure first
- No launch without numbers we trust.
- Test before shipping
- Every system got a security test before it went live.
