MM Finance Cronos
Summary
MM Finance (also known as Mad Meerkat Finance) was the largest decentralized exchange on the Cronos blockchain. On May 4, 2022, the protocol suffered a frontend compromise in which an attacker injected a malicious router contract address, redirecting approximately $2 million in user funds to the attacker's wallet over roughly three hours. The stolen funds were laundered via Tornado Cash and routed through OKX; the team pledged reimbursement via trading fee airdrops, though full recovery of stolen assets was not confirmed. The MMF token subsequently lost approximately 99.9% of its value from its April 2022 all-time high.
