You’ve executed a buy order successfully and things look promising—until the sell order simply vanishes. Your transaction gets validated, yet it never appears on Solscan.

**Potential Causes:** This situation could be linked to how you’re setting your blockhash slot expiry. If it’s set too short, transactions might time out before they are properly logged on the blockchain.

**The Workaround:** Reevaluate your blockhash expiry settings. Setting this to a slightly longer duration can give your transactions a buffer to complete and register, ensuring they’re not lost in the rapid pace of Solana’s environment.

#### Is MEV Without a Validator Leadership Possible?

There’s a common misconception that MEV on Solana can only be performed effectively if you’re the leader validator. But with the right know-how and tools, it’s feasible even without holding that position.

**How to Navigate:** Implement Rust and tools like Jupiter to streamline your processes. The key here is speed—completing actions in as little as 80ms or less significantly ups the chances of successful execution. By utilizing Jito for direct connections to validators and leveraging advanced tips, those who are informed and prepared can navigate MEV successfully.

#### Final Thoughts: Consistency and Connection are Key

Taking on Solana MEV challenges requires more than just technical skills; it demands persistence and a strong network. Reach out to experts and communities—they’re invaluable resources as you refine your approach. Understand that while no method can promise profitability, combining speed, knowledge, and strategic connections enhances your chances of success.

Remember, tackling the world of Solana MEV isn’t just about understanding blockchain—they’re about mastering the strategy and technology that drive today’s digital investments. Keep pushing the limits, stay informed, and don’t be afraid to ask for help along the way!
