Clober Liquidity Vault
Summary
Clober is a fully on-chain order book DEX (Decentralized Exchange) for EVM networks, built on the proprietary LOBSTER algorithm, which launched on February 14, 2023. Its Liquidity Vault product, a hybrid order-book/AMM product launched on Coinbase's Base network in December 2024, was exploited for approximately 133.7 ETH (~$501,000) within days of launch due to a reentrancy vulnerability introduced in post-audit code changes. The attacker ultimately moved the stolen funds through Tornado Cash after on-chain bounty negotiations failed.
