Cryptocurrency exchanges are moving to block scam-linked transfers before funds leave their platforms as fraud losses continue to climb.
Crypto exchange OKX has expanded its relationship with blockchain analytics company Chainalysis by integrating Alterya, a fraud-detection platform designed to identify scam-related payment destinations before funds are sent.
The partnership reflects a broader shift among exchanges from post-transaction blockchain monitoring toward earlier intervention, particularly in cases where users are persuaded to transfer funds to scam-controlled accounts, OKX told Cointelegraph.
Alterya analyzes scam infrastructure across websites, social media and messaging channels, and links those signals to financial identifiers such as crypto wallets and bank accounts. Integrated into withdrawal flows, the system allows exchanges to flag or block transfers to addresses believed to be associated with active scams.
