Approve wire transfers.

Wire fraud is a $2.9 billion problem because approval is a signature line on a PDF or a spoken confirmation on a phone call. Neither cryptographically binds the approver to the amount, the recipient, or the moment.

The change: Multi-approver signed authority chain per payment.

How it works

Four steps · every step signs a receipt.

1

Sender initiates the wire in the Vault · amount, recipient, purpose

2

Policy-required approvers receive a signed authorization request bound to those specific parameters (not a generic 'approve' link)

3

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

4

Once the chain is complete, the wire executes with the full signed authority record traveling alongside it

Evidence

The proof this actually works.

  • The signed authority chain is exportable · downstream systems and auditors can verify the chain without querying H33
  • Replay reconstructs the exact conditions of the approval — who signed, from what device, under what policy
  • If the wire is challenged, the receipt is a cryptographic answer, not a spreadsheet reconstruction
  • Edge case: Under-duress approval: policy can require geographic and device attestation, so 'they made me sign in the parking lot' becomes falsifiable
  • Edge case: Time-limited authority: the delegation can expire · after the window, the signature is invalid even if the credentials are unchanged
