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
