Blockchain security firm SlowMist has detected a critical vulnerability in four.meme’s liquidity system, raising serious concerns about security risks on the BNB Chain meme launchpad. This flaw allowed an attacker to manipulate the platform’s smart contract, exploiting its token launch and liquidity pool. Four.meme, a relatively new meme coin launchpad, has already faced security issues in the past. The latest exploit took advantage of a function within its smart contract, enabling the attacker to acquire pre-launch tokens before they were officially available. By sending these tokens to a PancakeSwap address that had yet to be created, the attacker managed to set up a liquidity pair and bypass the platform’s transfer restrictions. As a result, the attacker was able to manipulate liquidity pricing and drain assets from the liquidity pool. This incident is not an isolated case. Back in February, four.meme suffered a separate security breach that led to a loss of approximately $183,000. In that attack, the exploiter manipulated liquidity by creating a fraudulent liquidity pool on PancakeSwap V3 before the real one went live. In response, four.meme temporarily halted liquidity functions and reassured users that protective measures would be implemented. Following the latest attack, the four.meme team issued an urgent statement acknowledging the security breach. They suspended the liquidity pool (LP) on PancakeSwap to contain the damage and are working to strengthen security protocols. However, these repeated breaches highlight the ongoing risks in decentralized finance ( DeFi ) platforms and emphasize the need for robust security measures to protect user funds. This comes at a time when PancakeSwap, a leading DEX on the BNB Chain, is experiencing significant growth. In February 2025, its trading volume surged to levels not seen since 2021, with its total cumulative volume surpassing $1.1 trillion. Meme coins and BNB Chain’s recovery have fueled this expansion, with PancakeSwap commanding a dominant share of the BNB Chain’s DEX market. Despite its success, security incidents like the four.meme exploit underline the vulnerabilities within DeFi ecosystems. As meme coins and decentralized exchanges gain traction, ensuring security and protecting investors becomes increasingly important. Users should remain cautious and conduct due diligence before engaging with new projects, while developers must prioritize security to maintain trust in DeFi platforms.
