Jito bundles

Atomic, ordered execution and bidding for inclusion via the Jito Block Engine.

A Jito bundle is a set of transactions that execute all-or-nothing, in the exact order you specify. You attach a tip, and the Block Engine runs an auction - the highest-tipping bundles win inclusion and ordering.

Send a bundle

bundle.ts

const result = await rpcedge.sendBundle({
  transactions: [setupTx, arbTx, cleanupTx], // all-or-nothing, in order
  tipLamports: estimateTip(),                 // bid for inclusion
});

Tip vs priority fee

They are not the same. A priority fee is paid to the leader and raises your place in normal prioritization. A Jito tip is paid to a Jito tip account and is what makes your bundle win the auction. Competitive bundles use both.
