Recently, I realized that many people still do not fully understand mev bots and how they operate on the blockchain. These bots are truly a major issue on Ethereum; they profit by manipulating transaction orderings and capturing opportunities from our DeFi trades.

There are quite a few different types of mev bots. Some arbitrage bots look for price differences between DEXes and exploit them. There are sniping bots that buy before large transactions and sell afterward. Front-running bots prioritize placing their transactions ahead of other large trades. Others monitor transactions following big orders, and flash loan bots use flash loans to manipulate the market. In fact, I found over 30 different types of mev bots, so this problem is more complex than it seems.

The question is how to protect yourself. I have a few practical strategies. First, set lower slippage; although this can reduce the risk from mev bots, setting it too low may cause your transactions to fail. Second, trade on high-liquidity pools, because mev bots rely on price differences, and larger pools can lessen the impact of a single trade on the price. However, this method has limitations, especially with new tokens.

If you're using Ethereum, try Flashbots Protect. Visit their website, click on setup, select protection, and then add it to your wallet. If that’s not effective, you can try manually adding a MEV-blocking RPC to your wallet.

For Solana, it’s a bit different. I recommend lowering slippage to 1.5%–2%, since higher slippage increases the risk of being exploited by bots. You can also use MEV mitigation tools like Telegram bots Trojan or Maestro.

Overall, mev bots remain a silent threat on the blockchain, especially on Ethereum. To protect your assets, apply measures like reducing slippage, trading on high-liquidity pools, and using tools such as Flashbots Protect or MEV Blocker. Raising awareness and taking proactive steps can significantly reduce the risk of losses caused by mev bots.
