Backend: amount-mismatch check runs after payment saved and offers accepted

Severity: medium Domain: Payment Labels: bug, backend, logic

Description

In paymentController.ts:886-889, the check comparing storedAmount vs amount is executed after the payment has already been saved and offers accepted. If there is a mismatch, those side-effects cannot be rolled back, potentially leaving the system in an inconsistent state.

Options

  1. Move the storedAmount vs amount check before saving/advancing/accepting offers.
  2. Wrap the verify flow in a transaction and roll back on mismatch.
  3. Validate amount at intent-creation and re-check before completion.

Recommendation

Reorder so the amount-mismatch check (and ideally a transaction) gates all side-effects. This is a control-flow/business-logic change.
