What to Do in the First Minutes After a pump.fun Launch

The bundle landed. The coin exists, your wallets bought, and somewhere a chart has started drawing. This is the moment people make their worst decisions, usually by clicking something in the first ninety seconds that they would never have chosen with a cooler head.

Here is what is worth doing, in order, and what is worth not doing.

#Minute one: confirm the launch did what you planned

Before you look at the price, look at your own wallets. On mainnet a Jito bundle is all or nothing, so if the coin exists, every buy in the bundle landed too. Still, check the numbers match your plan.

After a launch, DevBundler drops you on the coin's project dashboard. It shows:

• Market cap and bonding curve progress.
• Your wallets' combined holdings and their share of supply.
• The value of those holdings if sold now.
• Profit and loss, combined and per wallet, unrealised and realised.
• Each wallet's entry market cap.
• A market cap candle chart, with your own buys and sells marked as B and S.
• Trade history.

#Minute two: tell people it exists

A coin nobody hears about does not get buyers. Post the coin address from the Twitter or Telegram you linked in the coin details. That link between the coin's socials and the account posting the address is how buyers confirm the coin is yours and not a copy.

Copy the address from the dashboard rather than typing it. A wrong character sends people to a different coin, or nowhere.

#Read the numbers that matter

New coins move fast and the price of a single token is a tiny, unintuitive number. Two other figures tell you more.

Market cap is the token price times the total supply. Since every pump.fun coin has the same supply, market cap is the easiest way to compare where coins are, which is why a market cap chart is easier to read than a price chart.

Bonding curve progress is how much of the sellable supply has gone. When it reaches the end, the coin migrates to PumpSwap. Your own launch already took some of it: DevBundler's default bundle of 1 SOL dev plus three 0.5 SOL buyers leaves the curve about 10% sold before anyone else buys. Reading the bonding curve progress bar explains what the bar does and does not tell you.

#Trading from your wallets

On the trading bar, tick the wallets you want, or All, then press a buy preset in SOL or a sell preset in percent, or type a custom amount. Presets are editable, and there are keyboard shortcuts if you want to act quickly.

On mainnet there are two ways to send a multi-wallet trade:

Speed presets set the priority fee: Normal, Fast, or Turbo (Premium). Higher fees help transactions get scheduled when the network is busy.

Every wallet in a batch is quoted in order. That matters most for sells. If five wallets each sell into the same unmoved price, the later ones fail their slippage check with error 6003, because the earlier sells already pushed the price down. Quoting each wallet after the ones before it keeps every minimum reachable. How to sell across multiple wallets goes into the details.

#What not to do in the first minutes

Meme coins are speculative. Many never get much past their launch. If yours does not take off in the first minutes, that is common, not a sign you did something wrong. Nothing here is financial advice: it is how to keep your decisions deliberate.

#Keep an eye on your own share

Your combined share of supply is not fixed after launch. It drops as you sell and rises if you buy more from your wallets.

The dashboard shows your combined holdings as a percentage of supply at all times. Glance at it before every trade. A buy from all wallets at once pushes that number up, and a large sell from all of them pushes the chart down. Keep that share at a level you planned for.

#If the curve completes

If enough people buy, the curve sells its 79.31% and the coin migrates to PumpSwap, pump.fun's AMM. Buys against the old curve stop working at that point and fail with error 6005, BondingCurveComplete. In DevBundler you do not need to do anything: trading switches to PumpSwap automatically, and the dashboard keeps tracking your wallets.

#The next step

Write down your exit rules before your next launch, not during it. Planning your exit on a meme coin gives a simple way to do it. If you have not launched yet, start with how to launch a pump.fun coin with a bundle.
