Shock Wave Hits BNB Chain! $120K Vanishes in Four.Meme Sandwich Attack – What’s Next for BNB?

Four.Meme, a memecoin launch platform based on the BNB chain, suffered a $120,000 sandwich attack exposing weaknesses in their pre-launch liquidity system on March 18, 2025. An attacker causes a sandwich attack by creating a trade that surrounds it, driving up the price and benefiting from the spread. Four.Meme stopped all token releases to look into the hack following the breach. This event underscores rising DeFi security threats, the main one being liquidity control. With improved security procedures in place, it has reopened and offers a more stable trading environment.

Four.Meme Exploit: A Wake-up Call about BNB Chain Security

The Four.Meme exploit exposed fundamental flaws in decentralized token launches whereby liquidity pools might be tampered with before official trading begins. Using imperfect smart contract systems, the attacker executed several quick transactions to drain $120,000 from liquidity. In automated market maker (AMM) systems, where low liquidity defense measures can lead to price manipulation, this kind of vulnerability is standard.

It stopped its launch events in reaction and froze transactions to limit the damage. Working with companies in blockchain security, the team found the vulnerability, fixed weaknesses, and stopped the next assaults. This event raises questions about the safety of BNB chain-dependent DeFi projects, which hackers have been attacking frequently.

Its choice to suspend operation was required to regain consumer confidence, but it also brings attention to a bigger issue in the entire sector: DeFi platforms are very susceptible to assaults, with liquidity pool exploits becoming more and more typical. The top priority should be guaranteeing early security and stopping price manipulation for DeFi initiatives and memecoin. Let’s have a look at BNB price prediction to see how this hack impacts the price of BNB.

BNB Price Prediction

The chart underlines significant resistance just below $644 and supports a close to $614. BNB tried to maintain an upward channel but met rejection at the resistance level, which resulted in a drop. Many breakouts followed, but every upward movement found resistance in selling that drove the price down. The recent fall implies eroding strength; nevertheless, a possible rebound is developing close to the support.

Chart 1: Analysed by vallijat007, published on TradingView, March 19, 2025

RSI at 46.77 signals neutral momentum, that is, neither oversold nor overbought. Overbought levels caused selloffs, earlier RSI signals imply, while oversold readings brought brief rallies. The MACD indicated a golden cross, which could suggest a bullish change. Still, an earlier deathcross signal points to remaining bearish pressure. Traders need to look for proof of a continued trend or more downward movement under support.

Whether buyers can maintain price levels above $620 will determine BNB’s future direction. A retest of $630-$640 is feasible if bullish momentum picks up. A lack of holding support could create even more downward pressure with possible drops toward $610 or under. BNB’s next move will be affected by trading volume, market sentiment, and general crypto developments.

Strengthening DeFi Security Post-Four.Meme Exploit

Particularly in liquidity protection and intelligent contract vulnerabilities, the $120,000 exploit on Four.Meme exposes major flaws in the DeFi system of the BNB chain. Even if it has reopened with more stringent security procedures, the assault demonstrated the dangers of sandwich attacks in automatic market maker (AMM) platforms. BNB fluctuates between key support and resistance levels. Growing bullish momentum could allow for a retest of higher levels, but more downside would result from an inability to maintain support. Long-term stability depends on DeFi security getting stronger.
