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.
- 5 signalsweighed before any money moves
- 4 levelsof response, from silent to paused
- On-devicemessage checks, nothing uploaded
- ₹0at stake while you try the demo
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.
- Reads the payment
Who it is going to, how much, and how you arrived at the screen.
- Weighs the situation
Each signal that fits adds weight. No single one decides alone.
- 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.

The layer in between
You keep paying the way you always have. WallUPI watches the moment the money is about to move, and speaks up only when something is wrong.

- Built for
- 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.
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.
-
01 · The hook
A message: your account is blocked. Act now.
-
02 · The pressure
A call. They sound official, and they stay on the line.
-
03 · The rush
Pay a small fee to fix it. Right now, while they wait.
