Do you know what’s happening to your cryptocurrency wallet while you sleep? Thousands of MEV bots are operating on the Ethereum blockchain right now, and they’re profiting from your transactions in ways most people don’t even realize.

What is an MEV bot? Essentially, these are automated bots capable of manipulating transaction orderings on the blockchain to generate profits. They work by observing pending transactions on the network and quickly inserting their own transactions before or after them. I’ve researched and found that there are over 30 different types of MEV bots active in the DeFi market.

The main strategies used by these bots include: arbitrage bots between DEXs, sandwich bots that buy and sell around large transactions, front-running bots that execute trades before important transactions, back-running bots that follow to profit, and flash loan bots that use quick loans to manipulate the market. Each strategy is designed to exploit price opportunities that most users are unaware of.

But there are ways to protect yourself. The simplest method is to lower your slippage (slippage), which can reduce the chances of MEV bots exploiting your transactions. However, be careful—setting it too low might cause your transactions to fail. Another approach is to trade in large liquidity pools, as these pools reduce the price impact of each transaction, making it harder for bots to profit.

There are some useful tools you can use. Flashbots Protect is a popular option—you just need to visit their website, click setup, and add it to your wallet. If that doesn’t work, you can try MEV Blocker by adding an MEV-blocking RPC to your wallet.

If you’re a Solana user, a different strategy applies. Keep your slippage around 1.5% to 2% to avoid becoming a target for MEV bots on SOL. You might also consider using dedicated Telegram bots like Trojan or Maestro, which are designed to counter MEV attacks on this network.

This warning about MEV bots isn’t meant to scare you but to help you better understand how the DeFi market operates. By implementing these protective measures—adjusting your transaction settings and using specialized tools—you can significantly reduce the risk of being targeted by MEV bots. The key is to stay aware and actively safeguard your assets on the blockchain.
