Crypto exchange OKX has integrated Alterya, a fraud‑detection system from Chainalysis, into its withdrawal flow to screen recipients before funds leave the platform. The addition extends OKX’s use of analytics beyond traditional post‑transaction tracing and toward earlier intervention in cases where users are persuaded to send funds to scam‑controlled accounts.
Alterya links scam infrastructure observed across websites, social media and messaging channels to financial identifiers such as crypto wallets and bank accounts. When a user initiates a withdrawal, the tool can flag or block transfers to addresses that match patterns tied to active scams, money‑mule networks, or other illicit actors.
This recipient‑focused approach contrasts with conventional anti‑money‑laundering measures, which largely focus on the sender through KYC and transaction monitoring. By identifying risky counterparty addresses before transfers clear, exchanges can prevent victim losses rather than only tracing and freezing funds after the fact.
Chainalysis acquired Alterya early last year in a deal reported at roughly $150 million, broadening the firm’s offerings from blockchain tracing into real‑time payment fraud prevention. Alterya previously worked with major platforms including Coinbase and Binance. Chainalysis says the system watches more than $23 billion in monthly transaction volume and helped avert about $300 million in losses over the prior 12 months.
The OKX integration comes as exchanges and payment providers increase adoption of real‑time risk scoring and fraud intelligence. Firms long known for transaction tracing and sanctions screening, such as TRM Labs and Elliptic, now offer wallet‑level risk signals and APIs that can be embedded into withdrawal and payment flows. For example, TRM Labs has partnered with banking infrastructure provider Finray Technologies to deliver cross‑chain real‑time risk alerts, illustrating the growing intersection of crypto compliance and traditional financial controls.
Despite expanded tooling, scam losses remain high. Chainalysis estimates roughly $17 billion was lost to crypto‑related scams in 2025, with impersonation scams—fake investment sites or individuals posing as trusted entities—showing the largest jump year‑on‑year (about 1,400%).
