Four.Meme Exploit Hits BNB Chain Meme Launchpad Again

Key Points

• Four.Meme Exploit Hits BNB Chain Meme Launchpad Again
• SlowMist identifies a critical vulnerability in Four.Meme’s smart contract.
• The exploit allowed liquidity manipulation and bypassed token restrictions.
• This follows a $183,000 loss from a February security breach.
• The incident raises concerns about BNB Chain’s DeFi ecosystem security.

The meme coin launchpad Four.Meme, built on the BNB Chain, has been hit by a major security exploit, exposing critical flaws in its smart contract. Blockchain security firm SlowMist uncovered the vulnerability, which allowed an attacker to manipulate the platform’s liquidity system and steal funds.

Launched recently, Four.Meme has already faced multiple security challenges, including a previous exploit in February, which resulted in a $183,000 loss. This latest breach has once again raised concerns about the security of decentralized finance (DeFi) projects on the BNB Chain.

🚨SlowMist Security Alert🚨

The attacker purchased a small amount of tokens before launch through the 0x7f79f6df function of @four_meme_, and used this feature to send tokens to a specified PancakeSwap Pair address that had not yet been created.

According to SlowMist’s findings, the attacker took advantage of a smart contract function (0x7f79f6df) to acquire pre-launch tokens and send them to an uncreated PancakeSwap pair address. This enabled the attacker to add liquidity without actually transferring the unissued tokens, effectively bypassing security restrictions.

Once the pair was established, the attacker manipulated the token price and drained liquidity, leading to significant financial losses for users.

“Why would the pool be emptied after the platform was fairly launched? If there is such a loophole, do all coins have this risk?” asked a concerned user, Wick, on X.

@four_meme_ 我意思你们看下，为什么平台公平发射后会被掏池子？

如果是有这样的漏洞的话，是不是所有币都存在这种风险？你们赶紧看下@heyibinance 一姐你也看下这个情况，这是个大事，不是闹呢

The Four.Meme team quickly responded, acknowledging the attack and suspending liquidity pool operations on PancakeSwap to mitigate further damage.

Security vulnerabilities in the crypto space are becoming more frequent, with multiple high-profile attacks in recent months. Crypto scam emails targeting Coinbase and Gemini have also raised concerns about phishing risks, while other platforms struggle with smart contract exploits.

🚨 Emergency Announcement 🚨

We are currently experiencing a malicious attack, and our team has intervened immediately to address the issue. To ensure security, token LP launched on @PancakeSwap is temporarily suspended, and will be reopened once our development team completes… pic.twitter.com/kll3tI5Pme

What This Means for PancakeSwap and BNB Chain

This exploit comes at a time when PancakeSwap, one of the largest decentralized exchanges (DEX) on BNB Chain, has been experiencing rapid growth. In February 2025, PancakeSwap recorded a trading volume of $81 billion, its highest since 2021, bringing its total cumulative volume to over $1.1 trillion.

However, incidents like the Four.Meme exploit highlight the security risks within the DeFi ecosystem. While BNB Chain’s popularity continues to grow, vulnerabilities in smart contracts pose serious threats to users’ funds and overall trust in the platform.

This is the second attack on Four.Meme in just two months, indicating deeper flaws in its security architecture. The February attack involved fake liquidity pools on PancakeSwap V3, leading to significant financial losses. In response, Four.Meme paused liquidity operations and promised stronger security measures—yet, this latest breach suggests that vulnerabilities still persist.

Meanwhile, other crypto developments continue to shake the industry. A whale’s massive Bitcoin short on Hyperliquid recently led to a $420 million battle, showing the impact of large trades on the market.

The Growing Need for Stronger Crypto Security Measures

With meme coins and DeFi projects gaining massive traction, ensuring robust security measures is more crucial than ever. Users are advised to conduct thorough research before engaging with new platforms, while developers must prioritize security upgrades to prevent future exploits.

The rise of meme coins has fueled speculation across the crypto space. However, security remains a concern. Even well-established firms like MicroStrategy continue investing in Bitcoin, as seen in their latest $10.8 million Bitcoin purchase, highlighting a growing institutional interest in safer crypto assets.

At the same time, XRP’s new unlock proposal could free up $1.5 trillion in liquidity for the market, according to recent reports. The XRP liquidity proposal aims to streamline financial transactions, potentially benefiting the wider crypto ecosystem.

As the DeFi space evolves, the battle between innovation and security remains ongoing. Whether Four.Meme can recover from this latest attack remains to be seen, but it serves as yet another reminder that security must be a top priority in the crypto world.
