Approve vendor payments.

Vendor invoice fraud is the largest single category of B2B payment loss. Approval typically means someone clicked 'ok' in the ERP. No cryptographic binding between the approver, the amount, the recipient bank, and the moment.

The change: Every vendor payment ships with its signed authority chain.

How it works

Four steps · every step signs a receipt.

1

AP flags an incoming invoice · the payment is drafted with amount, vendor, purpose

2

Policy-required approvers (per amount tier · per department · per vendor risk profile) receive signed authorization requests

3

Each approver signs with biometric-attested identity · the chain accumulates authority + policy + evidence + preconditions

4

Payment executes only when threshold is met · the signed authority chain travels with the payment for downstream verification

Evidence

The proof this actually works.

  • Every payment ships with cryptographic proof of who approved it · no phone-call reconstruction
  • Invoice fraud pattern: adversary changes the recipient bank at the last moment · H33 binds the signature to the recipient at approval time
  • Replay reconstructs the exact conditions · if a payment is challenged years later, the receipt answers cryptographically
  • Edge case: Emergency payment outside policy: possible with executive override, but the override itself is a signed receipt · full accountability
  • Edge case: Cross-border vendor: cryptographic signatures work uniformly · no jurisdictional signature-law variance
