The gap

Why agents need trust

Agentic commerce is past zero. The protocols shipped; the trust layer between them did not.

projected US agentic-commerce volume by 2030 — 15–25% of e-commerce.

The composition

What Obsigna does

One composition, five layers — the path every agent transaction travels.

  1. Identity
    A Passport (SD-JWT-VC), issued once and held in the wallet.
  2. Delegation
    Scoped Mandates — spend limits, time bounds, MCC allowlists.
  3. Verification
    A decision in under 100 ms, speaking AP2, ACP, TAP and Web Bot Auth.
  4. Payment
    One abstraction over cards, x402/USDC and A2A bank rails.
  5. Transparency
    Every receipt signed, logged, and Merkle-anchored for replay.

The audiences

Built for every side of the transaction
