# 8.2 Identity-Bound Intent

In traditional systems:

* Identity is verified first
* Payments happen later
* Intent is inferred

In PTERI, these steps are **collapsed into one cryptographic action**.

A payment intent includes:

* Sender address
* Recipient address
* Amount
* Network parameters
* Optional privacy flags

The wallet signs this intent directly.

This means:

* Identity (wallet control)
* Intent (what is being done)
* Authorization (approval)

are all proven **simultaneously**.

> A valid signature proves *who approved what*, with no ambiguity.

There is no way to:

* Alter parameters after signing
* Replay an intent
* Separate payment from identity
