Simple Pricing.
Pay Only for Results.
Chargeback defense with no monthly fee — you pay 15% only when we win. The same cryptographic stack also signs AI output.
Done-for-you dispute defense. Pay only on wins.
Four Stripe apps that capture pre-dispute evidence, defend chargebacks automatically, recover failed payments, and score refund abuse across a cross-merchant network.
Evidence Vault
Before the Dispute
Captures 3DS, AVS, CVC, device fingerprint, and IP on every payment with 3-layer cryptographic timestamps (CertNode instant + RFC 3161 + Bitcoin OpenTimestamps).

Cross-merchant abuse scoring on every refund. When a serial refunder hits one merchant, every Sentinel merchant sees them.

Also: sign AI output cryptographically
A secondary use of the same cryptographic stack. Multi-model neutral, three-layer timestamps on every signing — for teams that also need EU AI Act Article 50 or FRE 902 framing. No subscription, no tier prediction.
