# 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 | | Time-insensitive swap | Maybe | Bundles cost tips; priority fees may suffice | | NFT mint / competitive action | Yes | Guarantees ordering within the slot | ## Core Concepts ### Bundle Anatomy A Jito bundle is a JSON-RPC request containing 1-5 base58-encoded signed transactions. The transactions execute sequentially and atomically within a single slot. ``` Bundle = [Tx1, Tx2, ..., TxN] (N <= 5) - All transactions must be signed - Transactions execute in order: Tx1
