Bundle Simulation

The process of executing a Jito bundle against the current chain state in a sandboxed environment to verify that all transactions in the bundle succeed and produce the expected outcome before committing real tips and submitting to the Block Engine. Simulation catches issues like stale state, insufficient balances, or failed arbitrage conditions, preventing searchers from paying tips for bundles that would fail on-chain. Jito provides simulateBundle API endpoints for this purpose.
