# Jito Bundle Submission for Solana

Jito bundles allow you to submit up to 5 Solana transactions that execute **atomically** — either all land in the same slot or none do. This is the primary mechanism for MEV protection and competitive transaction execution on Solana. Approximately 85%+ of Solana validators run the Jito-modified client, making bundles the standard for reliable, front-run-resistant execution.

> **EXECUTION SKILL — SAFETY WARNING**: Submitting bundles spends real SOL on tips. Always test with `--demo` mode first. Never submit bundles with real funds without explicit confirmation. Default to simulation/dry-run in all scripts and examples.

## When to Use Bundles

| Scenario | Use Bundle? | Why |
|----------|-------------|-----|
| Swap on illiquid token | Yes | Prevents sandwich attacks |
| Multi-step arbitrage | Yes | Atomic execution prevents partial fills |
| Liquidation | Yes | Competitive — tip determines priority |
| Simple SOL transfer | No | Priority fees are cheaper and sufficient |
