Solana-based trading platform GMGN has announced a compensation program for users who fall victim to sandwich attacks despite its newly launched MEV protection feature.
The update was revealed by GMGN co-founder Haze in a recent post addressing the rising wave of Maximal Extractable Value (MEV)-powered exploits targeting the platform. Haze explained that the influx of malicious bot attacks prompted the integration of an advanced MEV-protection system to shield traders from these manipulative tactics.
现在一直有恶意节点在夹人，而Jito的服务也有不稳定的地方。
从今天开始。
如果你使用GMGN开了MEV（防夹子），被夹了的话，请发Hash找官方人员。
验证确实是开了MEV被夹的。
我们会补给你。感谢大家一直的支持。

However, Haze admitted that while the protective measures significantly reduce the threat, they are not foolproof. As a result, affected users are encouraged to contact GMGN’s team for recourse. Victims can apply for compensation by submitting their transaction hash for verification through official channels.
“If it has been verified that MEV was enabled [during the attack] and you were sandwiched, we will compensate you,”
said Haze in the post.
The initiative comes after Solana-based trading applications were hit by a flurry of MEV attacks in April 2025. Data from AI Invest revealed over 260,000 sandwich attacks within a 30-day window, siphoning approximately 23,600 SOL from unsuspecting traders. Despite GMGN’s smaller trading volume compared to major platforms, it bore the highest attack impact ratio, accounting for about 30.8% of the total incidents.
Elsewhere in the industry, exchanges are also stepping up security against MEV exploits. Binance recently warned that accounts found using MEV bots to manipulate its Alpha Points rewards system risk suspension. Similarly, Bitget Wallet upgraded its security measures by integrating MEV protection across multiple blockchains, activating the feature by default to shield users from exploitative trading practices.
Typically, MEV sandwich attacks manipulate liquidity pools by artificially altering the prices of crypto assets, hence misleading traders with distorted market signals. GMGN’s latest compensation measure signals its commitment to restoring user confidence as the battle against MEV-driven exploits intensifies across decentralized finance platforms.
