pump.fun Launch Checklist: What to Check Before You Launch

A practical pump.fun launch checklist: coin details, wallets, SOL per wallet, supply split, Jito tip and the checks to run in the last five minutes before launch.

By DevBundler Team · · 5 min read

The short answer

Before a pump.fun launch, check four things: the coin details are final, every wallet is funded with its buy plus about 0.003 SOL (the dev wallet about 0.03 SOL more plus tip and fees), the total supply share is planned, and you are on the right network. A mainnet bundle is final once it lands.

Key takeaways

  • Coin name, ticker, image and description go on chain at creation, so finish them before launch day, not during it.
  • Fund each launch wallet with its buy plus about 0.003 SOL, and the dev wallet with roughly 0.03 SOL extra plus the Jito tip and platform fee.
  • Decide the combined share of supply your wallets will hold before you open the launch form.
  • Confirm the network. Mainnet uses real SOL and a landed bundle cannot be reversed.
  • Run the whole flow on devnet at least once if you have never launched before.

Print this, or keep it open in a second tab. Every item below is something that has stopped a launch, wasted SOL, or left a dev staring at a dashboard wondering why their wallets hold less than planned.

The short version: get the coin details final, fund every wallet with a margin, decide your total supply share in advance, and check the network before you confirm. The rest of this page breaks that into small, checkable items, grouped by when you should tick them.

Coin details: finish these days before

The coin's metadata is written when the coin is created. You do not get a second pass, so treat this section as the one to finish early, when you are calm.

Coin details

  • Name decided and spelled the way you want it to appear everywhere.
  • Ticker chosen, short and easy to type. Check it is not one letter off a well-known coin.
  • Image is square, clear at small sizes, and you have the rights to use it.
  • Description is one or two plain sentences about what the coin is.
  • Twitter, Telegram and website links are live and point to the right accounts, or left blank.
  • Someone other than you has read the name, ticker and description for typos.

If you are still deciding on any of these, how to pick a pump.fun coin name, image and description goes into what works and what tends to get ignored.

Wallets: set up and funded

A bundled launch uses a dev wallet plus up to 10 buyer wallets. Each one needs enough SOL to cover its buy and the small costs around it.

Wallets

  • Dev wallet chosen and labeled so you cannot pick the wrong one.
  • Buyer wallets generated or imported, and grouped together.
  • Each wallet holds its planned buy plus about 0.003 SOL.
  • The dev wallet holds its buy plus about 0.033 SOL (the same 0.003 plus about 0.03 for the coin), the Jito tip and the platform fee.
  • No wallet holds SOL it does not need for this launch.
  • You know how you will sweep SOL back out afterwards.

The 0.003 SOL per wallet is mostly the token account rent (about 0.002 SOL, refundable when the account is closed) plus network fees. The dev wallet's extra 0.03 SOL pays for the coin's own accounts. In DevBundler, the distribute tool can send equal or custom amounts to every wallet in a group in one step, and the launch table flags any wallet that is still short.

The plan: numbers decided in advance

Most bad launches are not technical failures. They are launches where the dev decided the split while the form was open and ended up holding more of the supply than they meant to.

The plan

  • Dev buy size decided, in SOL or as a percentage of supply.
  • Buyer wallet amounts decided, either the same for all or custom per wallet.
  • Combined share of supply across all your wallets written down.
  • Jito tip chosen. We suggest at least 0.005 SOL, more when the network is busy.
  • Total SOL for the launch added up, including fees.

For reference, on a fresh mainnet curve a 1 SOL first buy gets roughly 3.4% of supply. A dev buy of 1 SOL plus three buyers at 0.5 SOL each ends up holding about 8.18% together. If those numbers feel abstract, how to split supply across bundle wallets walks through real quotes.

Accounts and settings

Account and network

  • Logged in to DevBundler, session not about to lock from idle time.
  • On mainnet: no yellow Test network banner at the top of the page.
  • Lookup table ready. Picking the dev wallet prepares it, a one-time cost of about 0.005 SOL per account.
  • Priority fee and tip settings checked if the network is congested.

The last five minutes

This is the part people rush. Slow down for it. The launch table in DevBundler shows every wallet with its balance, its buy, its estimated share of supply and the SOL it needs, so read it once, top to bottom.

  1. 1

    Read the wallet table

    Every row should be green. A red row means that wallet is short and the launch button stays disabled until you fix it.

  2. 2

    Check the combined share

    Compare the total estimated percentage with the number you wrote down. If it drifted, change the buys now.

  3. 3

    Check the network badge

    Mainnet is red. If you meant to practice, switch to devnet in Settings first.

  4. 4

    Read the confirmation dialog

    It shows the totals, the fee and the tip. This is the last moment anything can change.

  5. 5

    Press launch once

    The app runs a quick pre-send check, then sends. Do not refresh or click again while it works.

That pre-send check confirms pump.fun is reachable, the coin address is unused, every wallet has enough SOL, and the buys will not sell out the whole bonding curve. If any of those fail, nothing is sent, and the project page shows the reason with a "Launch again" button.

Right after the launch

You will land on the coin's dashboard. The checklist does not stop here, it just gets shorter.

First minutes

  • Confirm the coin exists and your wallets hold what the table predicted.
  • Note the bonding curve progress and the market cap.
  • Check your combined share of supply on the dashboard.
  • Post the coin address to the socials you linked, from the accounts you linked.
  • Decide your exit rules before the chart starts moving, not after.

What to do in the first minutes after a pump.fun launch covers the dashboard and the trading bar in more detail.

Never launched before?

Do one dry run on devnet. It uses free test SOL and the same launch form, so you can tick every item above without spending anything. Just remember devnet has no Jito, so the transactions go out one after another, and its curve is set up differently, so the percentages will look wrong compared with mainnet. The full walkthrough is in how to launch a pump.fun coin with a bundle.

Frequently asked questions

›What do I need before launching a coin on pump.fun?

A name, a ticker, a square image, a short description, a funded dev wallet and, for a bundle, funded buyer wallets. Socials are optional but help buyers check the project.

›How much extra SOL should each launch wallet have?

About 0.003 SOL on top of its buy, which covers its token account rent and network fees. The dev wallet needs about 0.03 SOL more for the coin's own accounts, plus the Jito tip and any platform fee.

›Can I change my coin's name or image after launch?

Plan as if you cannot. The metadata is set when the coin is created, so treat the name, ticker, image and description as permanent.

›Should I test a pump.fun launch first?

Yes, if you have not launched before. Devnet uses free test SOL and runs the same flow, though its bonding curve is configured differently from mainnet so the percentages will not match.

›What is the most common reason a launch does not go out?

A wallet without enough SOL. DevBundler flags short wallets in red and blocks the launch until they are topped up, so nothing is sent half funded.
