OKX protected $1.1 billion in customer assets and blocked $26.3 million in direct scam losses during the first half of 2026, intercepting suspicious transactions before funds left the platform.
The broader Web3 ecosystem recorded 182 security incidents in H1 2026—a 50 percent increase in frequency compared to H1 2025—resulting in $956 million in total losses across the space.
Despite the surge in attack volume, overall crypto losses dropped 60 percent in H1 2026 versus H1 2025, reflecting improved defenses across the industry.
OKX runs Chainalysis Alterya, an AI-powered fraud prevention system that identifies and blocks transfers to known scam destinations in real time. Alterya builds on OKX's existing Chainalysis stack, which the exchange already deploys for compliance and law enforcement collaboration.
OKX also runs a bug bounty program offering rewards up to $1 million for discovered vulnerabilities, keeping security researchers incentivized to surface weaknesses before bad actors can exploit them.
The exchange undergoes regular Proof of Reserves audits to verify customer asset holdings. The most recent audit was completed in May 2026 by Hacken.
Following the Coldcard exploit, centralized exchanges including OKX recorded a spike in crypto inflows, with users shifting toward platforms offering institutional-grade security infrastructure in response to hardware wallet vulnerabilities.
The $956 million in total Web3 losses during H1 2026 makes clear that no single measure eliminates exposure—sophisticated phishing attacks and evolving exploits continue to drain funds across the ecosystem.
OKX's H1 2026 Web3 security semi-annual report details these figures.
