A security vulnerability was discovered in TMX-related contracts on the Arbitrum network, resulting in an exploit valued at approximately $1.4 million. Attackers minted and staked TMX LP tokens with USDT, then swapped USDT for USDG, unstaked, and sold the ill-gotten USDG tokens. The incident highlights potential risks within decentralized finance (DeFi) protocols operating on layer 2 solutions.
