And run them.The core of a front-running bot functions by listening for the pending transaction on the blockchain. Interacting with the blockchain using an interactive script, the bot buys before the buyer and sells right after it. The bot analyzes the trends of the crypto and executes transactions to make a profit. Front-running tactics on decentralized exchangesWhen a trade occurs, the system broadcasts it to the blockchain, requiring miners to verify the transaction. However, in any blockchain of significance, the stream of incoming transactions is more than the capacity of the subsequent block. Unmined transactions are left in a pending transaction pool called a mempool.Blockchain mempools are transparent, a feature that the front runners exploit. Getting insight into the mood of the traders, they are able to predict the upcoming price movements and place their own orders accordingly. They set a higher gas price on their transactions to encourage picking their transactions before the pending ones, thus front-running the unsuspecting traders. Ways to prevent front-running on the trader sideThere is no single solution to solve issues regarding front running on all platforms. Rather, various anti-front-running approaches need to be followed on different projects, depending on the scenarios.Use large liquidity poolsFront runners are fond of low liquidity pools, as there is less chance of competition as well as disruption of their transaction by a large order that unexpectedly alters the pool weighting. Executing your trades in large liquidity pools makes it less likely to get hit by frontrunning. Keep maximum slippage lowDoes the question “How do I avoid slippage” perennially pricks you? What you can do is set a maximum slippage tolerance in most decentralized exchanges. In other words, you can fix the maximum deviation from the expected return. An example will help you understand the scenario better.Suppose you place an order on a DEX and expect a return of 500 Tether (USDT) for it. If you set your slippage to 1% of your order, then you won’t be receiving less than 495 USDT. However, if higher slippage tolerance is greater, there will be more deviation.So, the formula is simple: Keep
