OKX and Chainalysis today announced an expansion of their relationship focused on proactive fraud and scam prevention. Building on OKX’s long-standing use of Chainalysis products to enhance compliance and support law enforcement collaboration, OKX will adopt Chainalysis Alterya to help protect customers by preventing transfers to known scam destinations before funds leave the platform.
Fraud and scams remain one of the most persistent consumer harms in crypto and beyond. Chainalysis estimates that $17 billion in crypto was stolen by scammers in 2025, and scams that leverage AI tools such as voice cloning and deepfake impersonation were 4.5 times more profitable than traditional scams.
OKX and Chainalysis have a track record of working closely with global authorities on compliance and fraud investigations. This has led to some of law enforcement’s biggest wins, including the largest-ever fraud-related seizure of crypto funds by the U.S. Department of Justice, and the freezing of nearly $50M in USDT linked to scam operations.
Alterya: proactive protection that blocks scam payments before they’re sent
Now, OKX will uplevel its commitment to mitigating crypto crimes in partnership with Chainalysis. OKX will adopt Chainalysis Alterya, an AI‑powered fraud prevention solution that detects scam infrastructure at inception across the web, connects those signals to financial identifiers (crypto wallets, digital wallets, bank accounts), and enables real‑time prevention of transfers to active scam accounts. This helps reduce financial losses related to authorized push payment (APP) fraud, lessen the number of customer disputes, and retain customers. Alterya monitors $23B+ in monthly transactions and helps protect hundreds of millions of users across crypto and fiat payment rails, focusing on recipient‑side risk and money‑mule detection, which is critical for stopping APP fraud. Over the past twelve months, Alterya has prevented more than $300 million in losses, supporting customers in proactively reducing fraud. Some leading exchanges have reported up to 60% fraud reduction after deploying Chainalysis prevention tools including Alterya.
Alterya also integrates with Chainalysis KYT (Know Your Transaction) compliance workflows, enabling pre‑withdrawal screening and evidence‑backed alerts (including domain screenshots and reconstructed chats) for efficient manual review, and providing webhooks and dashboards to operationalize prevention in high‑volume environments.
“OKX, and the entire industry, have a clear responsibility to build safe, trustworthy places where people can own and transact their digital assets. This means relentlessly enhancing our proactive defenses to block scams and fraudulent payments before they exit our ecosystem,” said Haider Rafique, Global Managing Partner, OKX. “The wild west days of crypto are over. What we’re building here is trust, radical transparency, and empowerment for millions.”
“Having a major global exchange adopt Alterya is a strong signal that remediation after the fact isn’t enough to stop fraud,” said Jonathan Levin, Co‑Founder and CEO of Chainalysis. “The best way to protect customers is to prevent scam payments in the first place – it’s both the right thing to do and a competitive advantage. OKX is leading by example and raising the bar for proactive scam prevention across the industry.”
