Why CertNode
Evidence before the dispute
Most merchants scramble to find evidence after a chargeback. By then, 3D Secure results and device data are gone. CertNode captures it at payment time.
Certified timestamps
RFC 3161 timestamps from an independent Time Stamping Authority. The same standard used in legal proceedings. Proof your evidence wasn't fabricated after the fact.
Lowest fees in the market
15% success fee vs Chargeflow's 25% and Disputifier's 20%. No monthly subscription. You only pay when we deliver results.
AI-written defense narratives
Claude analyzes your evidence and writes dispute-specific narratives with legal language tailored to Visa and Mastercard requirements. Not templates.
