Jito Bundles
A Solana transaction submission mechanism that groups multiple transactions into an atomic, priority-ordered bundle auctioned to block producers for same-slot inclusion — protecting trades from public-mempool MEV.
In detail
Jito Bundles are the Solana equivalent of Ethereum's Flashbots bundles. Instead of submitting a transaction to the public mempool where MEV searchers can observe and frontrun it, you submit a bundle (one or more signed transactions) with a tip to the Jito block engine. If the bundle is accepted, every transaction in it lands atomically in the same slot, in the order you specified. This is the foundation of all modern Solana MEV protection and is how Subglow's copy trader guarantees that the mirror transaction lands in the same slot as the target's transaction — denying searchers the window to sandwich you.
Key points
- Atomic, priority-ordered transaction groups
- Submitted to Jito block engine with a SOL tip
- Prevents public-mempool frontrunning/sandwiching
- Essential for copy trading, arbitrage, and liquidation bots
- Subglow submits every copy order as a Jito bundle by default
