# Jito bundle

A Jito bundle is a group of up to 5 Solana transactions that land in the same block, in order, or not at all.

## How it works

Jito runs a block engine that most Solana validators accept bundles from. A bundle is sent with a tip to one of Jito’s tip accounts. The validator runs its transactions one after another, and if one fails, none land.

- At most 5 transactions per bundle.
- All or nothing: a failed transaction drops the whole bundle.
- The tip is paid only if the bundle lands.

## Why launches use it

A coin launch on pump fun is a create transaction and buys. Sent separately, bots can buy between them. In one bundle, the create and the buys land together in the [launch block](https://unisongo.com/learn/launch-block).

## Worked example

5 transactions: the create, the dev buy, and 3 more with 2 team buys each. That is 6 team buys in the launch block. Unison budgets about 0.001 SOL for the tip. Jito’s public tip floor moves all day; on 12 Nov 2026 at 11:39 UTC its median was 0.00001 SOL and its 95th percentile 0.0071 SOL.
