How we do it
Replacing Tokens With Real-Time Intent Verification
Using machine vision, IronVest verifies the intent of the user to carry out a specific action, fused with the user's identity. If the user intent is verified, the transaction goes through. Otherwise, approval is rejected.
The experience is one customers already know - a simple scan-to-pair moment, with cryptographic certainty underneath.

Your phone is your key. Nothing to type, nothing to phish.

Why it holds
Three guarantees tokens can't make.
Overlay Malware Immunity
Machine vision verifies what the user sees on screen and compares it to the real transaction. Malware can't fake the out-of-band camera channel.
Transaction Binding
Every approval is cryptographically bound to the specific transaction. Intercepted or redirected codes are worthless, they can't be replayed on a different transaction.
Cryptographic Audit Trail
Every approval is signed and sealed, giving banks immutable proof of exactly what the user consented to — eliminating false dispute claims.
Attacks IronVest Reverse OTP eliminates
- Remote Guidance Fraud
- Session Hijacking

The Technology
A New Approach to Transaction Verification
IronVest guarantees that the transaction the user sees is exactly the one the bank executes, eliminating approval of altered or invisible transactions, closing the gap that soft and hard tokens can't detect.
IronVest breaks the attacker's control path - the malware on the desktop can't fake the out-of-band interaction or alter what the camera sees, so it becomes ineffective.
The process is simple for users, yet provides cryptographic assurance for the bank. With no confusing codes or pop-ups, customers find a modern UX that is familiar from "scan-to-pair" experiences.
