CertNode

CertNode runs four published apps on the Stripe App Marketplace covering the full lifecycle of payment-event accountability.

Reflex defends chargebacks automatically. Evidence package, defense narrative, and submission to Stripe in 60 seconds after a dispute fires. 15% of recovered amount on wins only, 40% less than alternatives, no monthly fee.

Vault captures pre-dispute evidence at payment time. 3DS, AVS, CVC, IP, device fingerprint, browser, and session data, all sealed with RFC 3161 certified timestamps. $0.03 per transaction.

Recover saves failed subscription and one-time payments with adaptive retry timing and dunning sequences tuned to merchant context. Success-fee pricing on recovered revenue.

Sentinel detects refund abuse across the merchant network. Flags repeat refund-abuse patterns before refund issuance. $49 per month flat, $39 with bundle, 14-day free trial.

All four apps share one cryptographic stack (ES256 JWS + RFC 3161 timestamps + optional Bitcoin anchor) so every payment event has a verifiable audit trail.
