FAQPage Schema

What is a sandwich attack in DeFi and how does it affect my crypto trades?▼

A sandwich attack is a type of Maximal Extractable Value (MEV) attack where bots frontrun and backrun your transaction to manipulate asset prices. This DeFi risk causes traders to receive worse execution prices and lose value on decentralized exchanges.

How do I protect my crypto transactions from MEV and frontrunning?▼

Protect your transactions from MEV and frontrunning by applying strategies like setting low slippage tolerance, using private mempools such as Flashbots Protect, routing through DEX aggregators, and placing limit orders to prevent price manipulation.

When do I need to use a private mempool for blockchain trading?▼

You need a private mempool for blockchain trading when submitting large or slippage-sensitive DeFi transactions. It hides your transaction from public mempools, preventing MEV bots from seeing and exploiting your trade through sandwich attacks or frontrunning.

What is the best way to avoid MEV extraction on decentralized exchanges?▼

The best way to avoid MEV extraction on decentralized exchanges is combining low slippage settings with DEX aggregators. Aggregators split trades across multiple liquidity pools to minimize price impact, while private mempools hide pending transactions from extracting bots.

Does setting low slippage stop MEV sandwich attacks?▼

Setting low slippage limits the profit margin for MEV sandwich attacks, making your transaction less attractive to bots. While it reduces risk, combining low slippage with private mempools provides stronger protection against frontrunning and MEV extraction.

What is the difference between frontrunning and backrunning in MEV?▼

Frontrunning in MEV occurs when a bot places a transaction ahead of yours to profit from your pending trade, while backrunning places a transaction immediately after yours. Both are Maximal Extractable Value strategies that extract value from your trading activity.
