Summary
ThalaSwap is the decentralized exchange component of Thala Labs, an Aptos-based DeFi protocol offering an AMM, the Move Dollar (MOD) overcollateralized stablecoin, liquid staking, and a launchpad. On November 15, 2024, an input-validation bug introduced in a two-line patch to the v1 farming contract allowed an attacker to drain $25.5 million in liquidity pool tokens; funds were fully recovered within hours after SEAL 911 identified the exploiter via on-chain evidence and the attacker returned assets in exchange for a $300,000 bounty.
