Coinbase collaborated with UK and US law enforcement agencies in an international operation targeting transnational scam networks operating in West Africa. The joint anti-fraud operation took place in London from October 6 to 9. Coinbase's global intelligence team tracked illicit fund flows, helped freeze involved assets and shared investigative leads in real time. Coinbase said some criminal networks are gradually shifting to regions such as West Africa as crackdowns on scam compounds in Southeast Asia intensify.
