On April 12, 2024, SumerMoney (a Compound fork) on Base was exploited via reentrancy vulnerability. An attacker used a flashloan and reentrancy call to manipulate exchange rates and redeem collateral at inflated rates, extracting approximately $310K worth of assets while bypassing proper accounting.

Sumer Money was exploited on the Base chain due to a smart contract vulnerability, which resulted in a loss of assets worth approximately $310,000. The root cause of the exploit is a lack of reentrancy protection, which led to the manipulation of the underlying assets.
