How Can a Trader Minimize the Risk of a Failed Transaction While Maintaining a Low Slippage?

A trader can minimize the risk of a failed transaction while maintaining low slippage by using a private transaction relay (like Flashbots) to prevent front-running, which is a major cause of failure. They can also split a large order into smaller, time-delayed chunks to reduce price impact, or use a DEX aggregator that routes the order through multiple pools to find the best execution path and price, thereby reducing the chance of exceeding the narrow tolerance.
