How to Launch a pump.fun Coin With a Bundle (2026 Guide)

Most pump.fun launches look the same from the outside. Someone creates a coin, buys a chunk with the dev wallet, and then scrambles to buy from a few more wallets before the snipers do. By the time the second wallet lands, three bots have already bought.

A bundled launch fixes the scramble. This guide walks through the whole thing: what a bundle is, what you need before you start, how to size the buys, and what actually happens when you press the button.

#What a bundled launch actually is

When you create a coin on pump.fun, the create instruction makes the mint and the bonding curve. Normally the dev buy rides in that same transaction, and everything else comes later.

A bundle takes the create transaction and the buys from your other wallets and hands them to Jito's block engine as one package. The validator either includes the whole package, in order, in one block, or drops it. There is no "half launched" state and no gap where an outside wallet can slip in.

1. Create + dev buy

   transaction 1 makes the coin and the dev wallet buys first

2. Buyer wallets

   transactions 2 to 5 carry up to 10 more buys, in the order you set

3. Jito tip

   the last transaction pays the tip that gets the bundle picked up

4. Same block

   all five land together, or none of them do

If you want the mechanics in more depth, how Jito bundles work on Solana goes through it transaction by transaction.

#Before you start

You need three things ready. Most failed launches we see are missing one of them.

The "little extra" matters. Every wallet needs about 0.003 SOL on top of its buy for its token account and network fees. The dev wallet needs roughly 0.03 SOL more, because it pays for the coin's own accounts, and it also carries the Jito tip and any platform fee. DevBundler works this out per wallet and refuses to launch if one is short, but it helps to fund with some margin anyway.

#How much each buy gets you

pump.fun starts every coin on the same bonding curve, so the first buys are predictable. On mainnet:

Each buy moves the price up, so the second wallet gets slightly fewer tokens for the same SOL than the first, and the tenth gets fewer still. That is the curve working as designed, not a bug. Why later bundle wallets get fewer tokens shows the numbers.

Here is a real split from a DevBundler quote, buying by percentage instead of SOL:

Same 2% target, rising cost per wallet. Together these four wallets hold 9% of supply and the curve is about 11% sold.

#Step by step in DevBundler

1. 1

   Fill in the coin

   Name, ticker, description, socials and image. The image uploads to IPFS while you review the launch, so it does not slow you down.

2. 2

   Pick the dev wallet

   Choosing it also prepares a reusable lookup table in the background, a one-time setup of about 0.005 SOL per account.

3. 3

   Tick your buyer wallets

   Up to 10. Then choose SOL amounts or % of supply, the same for everyone or custom per wallet.

4. 4

   Read the table

   Every wallet shows its balance, its buy, its estimated share and what it needs. Anything short is red and blocks the button.

5. 5

   Confirm once

   One dialog with the totals, the fee and the tip. Press launch and you land on the coin's dashboard.

There is no separate "test" step. Instead, the app does one fast check right before sending: it confirms pump.fun is reachable, the coin address is unused, every wallet has enough SOL, and the buys will not sell out the whole curve. If any check fails, nothing is sent and the project page tells you why.

#Choosing the Jito tip

The tip is what makes a block builder want your bundle. Too low and it can sit unpicked while the blockhash expires. Too high and you are paying for nothing. We suggest starting at 0.005 SOL and raising it when the network is busy. Jito tips explained covers how to judge it.

#Keep the total share sensible

A launch where your wallets hold 40% of supply tends to scare people off; one where it holds a modest share reads as a dev with skin in the game.

DevBundler shows the combined percentage before you launch and keeps showing it on the dashboard afterwards.

#After the launch

You land on the coin's dashboard: market cap, bonding curve progress, every wallet's tokens and profit, and a chart with your own buys marked. From there you can tick wallets and buy or sell across all of them at once.

#Try it on devnet first

Devnet uses free test SOL and runs the same app, the same launch form and the same dashboard. Note that devnet has no Jito, so the transactions go one by one, and devnet's pump.fun curve is set up differently from mainnet, so the percentages will not match. It is still the best way to learn the flow before any real SOL moves. See how to test your launch on devnet.
