How to Set Jito Bundle Tips Without Overpaying for MEV Priority

Overpaying Jito tips is the silent profit killer in Solana MEV strategies: too low and your bundle gets dropped, too high and the trade becomes unprofitable before it lands. This post explains tip floor discovery using the Jito tip stream, dynamic tip sizing based on real-time block competition, and back-of-envelope break-even math for snipers and arbitrageurs.

Building a Solana Copy Trading Bot with Geyser Wallet Tracking

Effective copy trading on Solana requires detecting a target wallet's transaction within the same slot it confirms and replaying the swap with adjusted size before price impact shifts — a challenge that requires Geyser streaming rather than polling. This tutorial covers target wallet selection heuristics, on-chain copy logic in Rust, and slippage guard rules to avoid copying into exit liquidity.
