He made several swamps in the USDC-USDT liquidity pool on the UNISWAP V3 platform and received only 18 & thinsp; $ 636 instead of 732 & Thinsp; 583. This happened because of the actions of a special MEV bot that used the unfinished transaction for pricing.
< P > The attacker used the classic Sandwich-attack scheme, which launches two transactions: one before the victim exchange, the other after him. This artificially increases the price of the asset that the victim buys and then the bot sells it at an inflated rate. In this situation, the manipulation was so large -scale that it led to the loss of more than $ 700,000.
< p > experts advise traders to follow certain safety measures to avoid such attacks. In particular, slippage should be reduced (a permissible deviation of the price during the swap), to choose platforms that use Mevbot protection mechanisms, such as Cowswap, and use special RPC servers that do not disclose the planned transactions.
~ ~ > < P > Some analysts suggest that this agreement could not just be a bad swap, but an attempt at money laundering. They drew attention to the complex asset movement scheme before the attack, which included transfers through Binance and Bybit exchanges, as well as the use of Aave and Compound platforms. This could be a way of whitening cryptocurrency through liquidity pools.< P > In recent years, sandwich-attacks have become more common in the cryptocurrency sector. In November 2024 alone, more than 35% of BNB Chain blocks were such attacks. This confirms the need to improve the mechanisms for the protection of traders and platforms of decentralized finances.
