Payment rail evidence trail

Map how FPS, card, wallet, and correspondent messages become audit-ready evidence inside your fintech stack.

Message logs from rails are not the same as an audit trail you can defend. We map inbound and outbound messages to internal postings, identify drop points where evidence disappears, and test whether dispute windows can still reconstruct the original path. You leave with a rail-to-ledger evidence map and interview notes for operations leads who answer partner diligence.

What you receive

  • Written findings operations and compliance can share without translation
  • A gap map tied to transaction types and override paths in scope
  • A prioritized remediation list sized to your partner or audit calendar
