# Solana Transaction (TX) Modes On Solana, selecting between **Auto**, **Jito**, and **Classic** transaction (TX) modes determines how your transactions are processed, particularly concerning speed, reliability, and protection against [MEV ](#user-content-fn-1)[^1]strategies. *** ## What is Jito? **Jito** is an advanced Solana validator client developed by [Jito Labs](https://www.jito.wtf/), designed to optimize MEV handling. Using Jito, users can submit bundles of transactions that are executed atomically, in order. This means all transactions in a bundle either succeed together or fail together, ensuring consistency and predictability for complex operations. To incentivize validators, users attach a **tip** (an additional fee) to their bundles, which are then prioritized based on these tips. This TX mode is useful for precise transaction ordering and execution. *** ## Transaction Modes * **Auto**: This mode automatically selects the optimal transaction path based on current network conditions. It may choose between Jito or Classic modes to balance speed, cost, and reliability. * **Jito**: This mode routes your transactions through Jito-enabled validators, leveraging the bundling and tipping system. It's useful for scenarios where atomic execution and transaction sequence are important. * **Classic**: This traditional mode sends transactions through the standard Solana network, without the enhancements provided by Jito. It's suitable for straightforward transactions where advanced MEV protection and bundling are unnecessary. Configure your transaction strategy on Solana based on your use case, optimizing for speed, reliability, and protection against MEV-related issues. If you aren't sure which mode to use, select **Auto**.
