Solana Transaction Landing: Jito Bundles vs Raw Spam Compared

Getting a transaction confirmed during high-traffic moments on Solana comes down to either paying Jito's block-engine tip or carpet-bombing validators with duplicates — and the cost-benefit calculus has shifted dramatically since local fee markets launched. We benchmark both approaches across five volatility scenarios and show when each strategy wins.

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.
