A scam-protection layer for UPI apps

A safety layer under every UPI payment

It sits under the payment apps you already use, and stops a suspicious transfer before your money is gone.

A check, frame by frame

What happens between tap and transfer

The payment from the demo that ends in a full stop: ₹2,200 to a number that just texted a fake KYC warning, with a call still connected.

  1. Reads the payment

    Who it is going to, how much, and how you arrived at the screen.

  2. Weighs the situation

    Each signal that fits adds weight. No single one decides alone.

  3. Speaks at the right volume

    Here everything points the same way, so the payment is held.

Illustration: a ₹2,200 payment is checked. Four signals are found, a suspicious message from the recipient, an active call, an unknown recipient and little payment history, and the risk reading climbs to 100, so the payment is paused.

Any UPI app that adds the layer

The app you can download is a demonstration UPI app, so you can watch the layer work in a real payment sequence without real money. The layer itself is built for other UPI apps to use.

Anatomy of a UPI scam

Scams don’t win because people are careless

They win because they are fast, and because they arrive dressed as something official. Almost every one runs the same four beats.

  1. 01 · The hook

    A message: your account is blocked. Act now.

  2. 02 · The pressure

    A call. They sound official, and they stay on the line.

  3. 03 · The rush

    Pay a small fee to fix it. Right now, while they wait.

  4. WallUPI
    steps in here
  5. 04 · The loss

    The money lands in an account that empties in seconds.

Every beat is designed to stop you thinking. WallUPI’s whole job is one clear, factual interruption between the rush and the loss.
