UPI / payment rails distribution
Products that nest inside UPI and payment habits reduce adoption friction and borrow trust from rails users already use daily.
Causal engine
User already trusts UPI → product attaches to a payment or payout moment → activation happens inside a familiar rail → retention follows utility.
Preconditions
- Your value connects to send/receive/pay flows
- Compliance and partner access are solvable
Anti-patterns
- Building a parallel wallet with no rail advantage
- Copying fintech UX without a Bharat-tier job
