Bundle (Jito)

An atomic group of up to five transactions submitted together through Jito's Block Engine, where either all transactions land in sequence or none do, enabling MEV strategies that depend on guaranteed transaction ordering without risk of partial execution. Bundles are submitted with a tip to incentivize the leader to include them; the Block Engine simulates bundles, selects the most profitable ones, and forwards them to the Jito-enabled leader. Bundles land at the top of a block before standard transactions, giving searchers execution priority.
