Case Study: Wallapop achieves stronger fraud detection and customer trust with LexisNexis Risk Solutions' ThreatMetrix

Intelligence from LexisNexis® ThreatMetrix® Helps Spanish Wallapop better Detect Fraudulent Activity Across the Customer Journey

Wallapop, a leading Spanish second‑hand marketplace with some 15 million users and more than 180 million items exchanged, faced growing fraud pressure as its peer‑to‑peer platform scaled. The company needed to protect buyers and sellers while preserving a smooth user experience—specifically to detect new‑account fraud, identify returning fraudsters using new identities, and maintain a secure, trusted marketplace.

Wallapop deployed LexisNexis® ThreatMetrix® and the Digital Identity Network to build a real‑time digital identity from device, location and behavior signals, using SmartID, mobile SDKs, TrueIP and expert services to spot anomalies. The solution significantly improved fraud detection accuracy and rates, flagged returning fraudsters before they caused harm, reduced manual reviews, and strengthened customer trust and operational efficiency.
