Jito vs Pump.fun Bundling: What's the Difference?
Updated January 2026 · SolBundler Team
Jito and Pump.fun: How They Relate
Jito is a Solana validator client that enables MEV (Maximum Extractable Value) bundles. Pump.fun is a token launchpad built on Solana. When we talk about "Pump.fun bundling" in 2026, we mean using Jito MEV bundles to execute buy transactions on Pump.fun simultaneously with token creation.
What is a Jito Bundle?
A Jito bundle is a group of up to 5 Solana transactions that execute atomically — meaning all succeed or none do. This atomicity is what makes bundling powerful: your token creation and all your buy transactions land in exactly the same block.
How Pump.fun Bundling Uses Jito
When you launch a token with SolBundler, the tool creates a Jito bundle containing: (1) the token creation transaction, (2-5) buy transactions from your bundle wallets. All execute in block 0, before any sniper can react.
Jito Tips and Priority Fees
Jito bundles require a "tip" paid to the block engine in addition to standard Solana transaction fees. In 2026, competitive tips range from 0.001 to 0.01 SOL depending on network congestion.
