Solana bundler: your token and your buys in one bundle

On Solana you cannot simply queue one transaction directly behind another. A bundle is how you get an order you can rely on: a short list of transactions, sent with a tip, that validators execute together, in sequence, or not at all. If one fails, none of them land.

For a launch that matters twice. The creation and the creator’s buys cannot be separated, so no bot can buy in between. And a launch cannot half-happen: either the token exists with your supply bought, or nothing was spent on buys.

People search for a Solana bundler, a bundler on Sol or a Solana memecoin launch tool and mean the same job: get a token live with their own buys inside it, then manage the exit. A launch tool covers the whole run; the bundle is one step of it.

1. Create

   Name, ticker, image and socials. Nothing is on chain yet.

2. Set up

   Pick the launchpad and Block-0 or Reserve, then set the buys.

3. Fund

   One figure, sent once, before the launch.

4. Launch

   The creation and your buys go out as one atomic bundle.

5. Sell and withdraw

   One sell for every launch wallet, then withdraw.

The same steps, with screens and limits, are in how to bundle a memecoin. For the category across chains see memecoin bundler, and for the mechanism see bundle tech.

Supported launchpads

Launchpad	Chain	Launch modes	Access
pump.fun	Solana	Block-0, Reserve	Open to everyone
StonkFun	Solana	Block-0, Reserve	Open to everyone

Every launchpad listed here is open to every account. Which modes each one offers is in the table.

pump.fun is a Solana launchpad built on a bonding curve that migrates to its own PumpSwap pool when it fills. Ballistic launches pump.fun tokens paired with SOL or USDC in Block-0, where the creation and your wallets’ buys share one bundle, or in Reserve, where part of the supply waits in a one-sided Meteora DLMM position above the market. Sells route through the curve before migration and PumpSwap after it. The pump.fun bundler in detail.

Every bundle ends with a tip transaction that pays the relay carrying it. A Block-0 plan fixes its tip when it is saved: 0.001 SOL on the default relay, which is that relay’s minimum, counted once per bundle in the one SOL figure. A Reserve launch bundle bids differently: at least 0.005 SOL, following live tips up to 0.05 SOL, raised by at least 0.002 SOL on each resend, up to five times, and the funding stage budgets for those resends.

All funding happens before launch. The funding page adds the buys, the creation, the tip and gas into one SOL figure; you send it once and Ballistic funds each launch wallet.

For a Block-0 launch you can fund through the CEX route, where each launch wallet’s first deposit comes from an exchange rather than your own funding wallet, or spread the deposits over a funding window. Funded that way, your and your team’s positions are not one obvious cluster on holder-map tools such as Bubblemaps. Instant direct funding and Reserve launches fund from your own funding wallet.

Nothing is funded at launch time. When you press Launch the bundle is sent straight away, from wallets that already hold what they need.

• Sell from every launch wallet in one action, before or after migration.
• Run auto-sell, auto-buy, limit orders or DCA across the launch’s wallets.
• Claim the creator fees the launchpad has accrued to your token.
• Withdraw SOL when you are done; the 5% platform fee is taken as funds leave the launch wallets.

• Block-0 puts your dev buy and your bundled buys inside the launch. A buy the launch cannot carry is refused at setup, never bought smaller.
• A Reserve launch adds one custody wallet, which holds the parked supply.
• A bundle lands your buys first. It does not promise a price, volume or profit.
• Holders are public on chain. A bundled launch puts a large share of supply in your wallets at launch.
