Four.Meme, a memecoin launch platform based on the BNB chain, suffered a $120,00 sandwich attack exposing weaknesses in their pre-launch liquidity system

Four.Meme, a memecoin launch platform operating on the BNB chain, fell victim to a $120,000 sandwich attack on March 18, 2025, highlighting vulnerabilities in its pre-launch liquidity system. An attacker performs a sandwich attack by placing an order that is "sandwiched" by another, quickly increasing the price and profiting from the spread. Following the breach, Four.Meme halted all token releases to investigate the hack.

The exploit at Four.Meme exposes deep-seated flaws in decentralized token launches, where liquidity pools can be manipulated in anticipation of the official trading commencement. The attacker, utilizing imperfections in the smart contract systems, executed several rapid transactions to siphon off $120,000 from the liquidity. This vulnerability is inherent in automated market maker (AMM) systems, where minimal liquidity defense measures can open the door for price manipulation.

In response, Four.Meme paused its launch events and froze transactions to mitigate the damage and cooperate with blockchain security firms to identify the vulnerability, patch the weaknesses, and prevent further attacks. This event sparks concerns about the security of DeFi projects reliant on the BNB chain, which hackers have targeted with increasing frequency.

Four.Meme’s decision to suspend operation was crucial to restore user trust, but it also highlights a broader issue within the entire industry. DeFi platforms are highly susceptible to attacks, and liquidity pool exploits are becoming increasingly common. The priority should be to ensure early security and prevent price manipulation for DeFi projects and memecoin.

As seen in the BNB price prediction, the chart shows significant resistance just below $644 and support close to $614. BNB attempted to maintain an upward channel but encountered rejection at the resistance level, leading to a decline. Several breakouts followed, but any upward movement found resistance from sellers, pushing the price back down. The recent fall suggests eroding strength, but a possible rebound is forming close to the support. RSI at 46.77 indicates neutral momentum, neither oversold nor overbought. Overbought levels, as seen earlier, brought about selloffs, while oversold readings performed brief rallies. MACD shows a golden cross, which could hint at a bullish change. However, an earlier deathcross signal indicates remaining bearish pressure. Traders should watch for evidence of a continuing trend or more downward movement.

Whether buyers can keep price levels above $620 will decide BNB’s future direction. A retest of $630-$640 is possible if bullish momentum increases. Failure to hold support could create even more downward pressure with potential drops toward $614 or lower. Trading volume, market sentiment, and overall crypto developments will influence BNB’s next move.

The $120,000 exploit on Four.Meme, a memecoin launch platform on the BNB chain, has exposed major flaws in the DeFi ecosystem, particularly in liquidity protection and smart contract vulnerabilities. The platform, known for its pre-launch liquidity system, fell victim to the sandwich attack on March 18, 2025.

Despite reopening with enhanced security procedures, the attack attests to the susceptibility of AMM platforms to such exploits, which can be used to manipulate prices and siphon off funds, especially in platforms with minimal liquidity defense measures.

Following the breach, which saw the attacker quickly siphon off $120,000 from the liquidity, Four.Meme stopped all token releases and froze transactions to cooperate with blockchain security firms in identifying the vulnerability, patching the weaknesses, and preventing further attacks.

The attack on Four.Meme is part of a broader trend of hackers targeting DeFi projects on the BNB chain, exploiting vulnerabilities in smart contracts and draining large sums of cryptocurrency.

As the crypto industry continues to evolve, the focus on DeFi security and best practices becomes paramount in ensuring the long-term stability and trustworthiness of the decentralized financial ecosystem.
