Vitalik Buterin, co-founder of Ethereum, sold 5,000 $DHN tokens for 65.19 ETH, valued at approximately $124,000. These tokens were received for free from Dohrnii Labs' treasury on January 29, 2025. Following the sale, Buterin minted 315,382 DAI. In addition, Buterin sold several meme tokens, including $FML, $SHIB, $VB, and $AWESOME, for a total of 71.69 ETH, worth about $136,684. The transactions involved removing liquidity from pairs containing these tokens and ETH. Separately, the BNB Chain-based meme coin launchpad Four.Meme suffered a smart contract exploit. The attacker manipulated liquidity pools on PancakeSwap by exploiting a vulnerability in the platform's liquidity mechanism. This allowed the hacker to bypass transfer restrictions, specifically the MODE_TRANSFER_RESTRICTED function, and steal approximately $130,000 worth of BNB tokens. The stolen funds were laundered through multiple PancakeSwap contracts and wallets, including FixedFloat. This marks the second exploit on the Four.Meme platform in two months. Four.Meme has since resumed operations after conducting a security review and has announced plans to compensate affected users.
