Blockchain security company SlowMist has identified a critical liquidity vulnerability affecting 4.MEME in its recent security advisory.
The most recently released 4.meme is the Meme Coin Launchpad, which runs on a BNB chain. The vulnerability has raised great concern given the previous security challenges of the platform.
4. Take advantage of meme details
According to SlowMist, the attacker exploited certain features within the smart contract of four memos and purchased the token before its official launch. Using the 0x7F79F6DF function, the attacker sent these pre-release tokens to the specified PancakesWap pair address that had not yet been created.
This allowed the attacker to establish a pair and add liquidity without forwarding unissued tokens. Therefore, they effectively bypassed active transfer restrictions prior to the official release of the token.
As a result, attackers were able to add liquidity at an unintended price, resulting in the stolen liquidity of the pool.
“…Why is the pool empty after the platform is launched fairly? If there is such a loophole, is there this risk for all coins?”
This is not the first time Four.Meme has faced security challenges. In February, the platform suffered a serious exploit, resulting in the loss of around $183,000. The attacker manipulated liquidity by creating a fake liquidity pool in PancakesWap V3 before the legitimate pool opened.
They exploited vulnerabilities within the platform. In response, the four members temporarily halted liquidity operations and assured users of fund security while ensuring stronger protections.
BNB Chain Meme Coin Platform has issued an emergency announcement acknowledging the malicious attack. The team immediately stepped in to address the issue and suspended the token liquidity pool (LP) launched in Pancakeswap to ensure security.
Pancakeswap and the impact on BNB chain
Recent exploits in 4.meme come when Pancakeswap, the major distributed exchange (DEX) of BSC, is experiencing significant growth. In February 2025, Pancakeswap reached its highest trading volume of $81 billion since 2021, with a total cumulative volume exceeding $1.1 trillion.
This surge is driven by the recovery of the BNB chain and growing interest in meme coins, with pancake waps controlling 90% of the BNB chain’s DEX market share.

However, security incidents such as those involving the Four.meme platform highlight vulnerabilities within the ecosystem. It also highlights the need for strong security measures to protect user funds and maintain trust in decentralized platforms.
Memecoin and Decentralized Finance (DEFI) platforms continue to grow in popularity, ensuring security and integrity become more and more important.
Users should also take care and conduct thorough due diligence before being involved in a new project. Meanwhile, platform developers must prioritize security to protect user assets and maintain the reliability of their Defi Ecosystem.
