Open to everyone

pump.fun sells each new token on a bonding curve. When the curve fills, the token migrates to PumpSwap, pump.fun’s own exchange pool, and trades there from then on. Ballistic covers both halves: the launch on the curve, and selling on either side of the migration.

The cheapest supply on a pump.fun curve is the first supply. Bots watch for new pump.fun tokens and buy the moment a creation lands. A creator who creates first and buys second is buying after them, at a higher price, and often selling into them later.

Bundling closes that gap. A bundle is a short list of transactions that Solana validators execute together, in order, or not at all. When your creation and your buys share one bundle, nothing can be placed between them.

The first transaction creates the token with your dev buy. In Block-0, your bundled buys are packed into the same bundle behind it, splitting the buy you configure evenly, and the tip closes it. A bundle carries at most four or five transactions, depending on the relay (four on the default one), and the launch fits inside that. A buy the launch cannot carry is refused at setup, never bought smaller.

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. After the launch bundle, the supply is handed on to your holder wallets in further bundles (the Clean build, described on the Block-0 page).

1. Create the token

   Name, ticker, image and socials, and the pair: SOL or USDC.

2. Set up the launch

   Choose pump.fun and a mode: Block-0 or Reserve. Set the dev buy and how much the launch buys.

3. Fund once

   The funding page shows one SOL figure that covers every buy, the creation, the tip and gas. Send it once; Ballistic funds each launch wallet from it before the launch.

4. Launch

   One click sends the bundle. Your token page opens with every launch wallet listed.

5. Manage and sell

   Sell from all wallets in one action, or set auto-sell, auto-buy, limit orders and DCA across them.

6. Withdraw

   Move SOL out when you are done. The 5% platform fee is taken as it leaves the launch wallets.

A pump.fun launch uses launch wallets that Ballistic generates and keeps separate from your primary wallet. They are funded at a separate funding stage before the launch, which keeps the launch itself fast: when you press Launch, every wallet already holds what it needs.

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 do not read as one obvious cluster on holder-map tools such as Bubblemaps. Instant direct funding and Reserve launches fund from your own funding wallet.

A Reserve launch is an atomic launch bundle with your buys in it. Once it confirms, one custody wallet opens a one-sided Meteora DLMM position far above the market and parks the supply there. That position holds only your token, so it sells nothing at today’s price; it turns into SOL only as buyers lift the price into it.

The custody wallet needs about 0.17 SOL on top of its buy for the position’s rent and its own later withdrawals. That is added at the funding stage, never at launch, and it comes back to you on withdrawal. More on Reserve.

Before migration Ballistic sells into the pump.fun curve. Once the curve is complete it sells through the PumpSwap pool instead. The token page’s sell covers every launch wallet either way, so you do not change anything when the token graduates.

pump.fun pays creators a fee on trading. Ballistic shows what has accrued to your token and claims it for you.

Ballistic charges nothing to create, set up, fund or launch. See pricing.

• 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 that does not land spends nothing on buys; the funds stay in your wallets.
• Block-0 lands your buys first. It does not promise a price, volume or profit.
• A bundled launch puts a large share of supply in your wallets at launch, and anyone can read a token’s holders on chain.
