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
