PumpFun Bundle
Launch a pump.fun token with the dev buy and bundle buys in the same Jito bundle.
PumpFun Bundle is a 6-step wizard. It creates a pump.fun token, buys with the dev wallet and up to 8 bundle wallets in block 0 through one Jito bundle (up to 100 bundle wallets in total - the rest buy right after it), and can add up to 200 snipe buys right after. The progress dots in the top right show which step you are on. Steps that don't apply to your buy mode are skipped.
Step 1 — Token details
- Image: click or drag and drop any image file. Required when you launch.
- Name and Ticker (the ticker is upper-cased as you type). Both are required.
- Description: shown on pump.fun.
- Social links (optional): Twitter/X, Telegram and website, written into the token metadata.
The image and a metadata.json are pinned to IPFS when you click Launch, not before.
Step 2 — Dev wallet and wallet pool
Dev wallet
Choose an existing wallet, or click + Create New to make one named Dev wallet. Set the dev buy (presets 0.05–2 SOL, default 0.01). The dev wallet needs the buy amount plus about 0.031 SOL for creation, rent, the 0.01 SOL bundle tip and fees. If it is short, you get a warning with the exact amount missing.
When any dev, bundle or snipe wallet is short, a Fund wallets panel lists the top-ups. Fund them From existing wallet, or with One-time deposit address from Phantom, another wallet or an exchange: the deposit is split across the short wallets as soon as it arrives (see Wallets → Fund from an external wallet).
Wallet pool
Create fresh Launch Wallet #N wallets (1–100 at a time), or click Select Existing. Click a wallet to select it and enter how much SOL to send it (0.05 by default). Then pick a source under Fund from... and click Fund N — ◎total. You can rename a wallet with the pencil icon.
Step 3 — Buy mode
| Mode | What happens | Next steps |
|---|---|---|
| Snipe | Fast follow-up buys, blocks 1-3 — not atomic, competes with other snipers on the same terms. Add as many wallets as you need. | 5 → 6 |
| Bundle | Guaranteed block 0 — up to 8 wallets buy atomically with the dev wallet in the same Jito bundle. More (up to 100) buy right after. | 4 → 6 |
| Launch + Bundle + Snipe | Combine both — atomic bundle wallets (up to 8 in block 0) plus as many additional fast follow-up snipe wallets as you need (up to 200). | 4 → 5 → 6 |
| Dev Buy Only | Launch with only the developer buy, no bundle or snipe wallets. | 6 |
Step 4 — Bundle wallets
- Click a row to assign it (0.05 SOL by default). You can assign at most 3. After that the other rows are disabled.
- Max and Max all set a buy to the wallet balance minus 0.003 SOL (token account rent and fees).
- The footer shows N/3 wallets assigned and the total buy.
- 🎲 Randomize (in the footer, for bundle and snipe wallets) lowers each amount by a random 0–15%, so the buys aren't identical.
Step 5 — Snipe wallets
This step works like step 4, but allows up to 50 wallets. Wallets already used for the bundle can't be picked again. Max leaves 0.004 SOL for token-account rent and network fees (the dev wallet pays the Jito tips).
Delay between wallets (0–5000 ms, default 0) spaces out the snipe buys: wallet i fires after i × delay. Zero fires them all at once. A small delay helps the buys look less identical.
Step 6 — Review, simulate, launch
- Check the totals
Wallets (dev + bundle + snipe), Total Buy, Dev Buy, and the bundle and snipe breakdowns.
- Simulate
Runs every transaction (dev, bundle, snipe) through a bundle simulation. Nothing is sent. You get Simulation: X/Y would land, with an error on any line that would fail.
- Launch Token
Metadata is uploaded, a new mint address is generated, and the bundle goes to Jito. The log streams live:
LAUNCH LOGUploading metadata to IPFS... Metadata uploaded: https://gateway.pinata.cloud/ipfs/bafk... Generated mint: 7Gq...pump Building create + dev buy instructions... Building buy instructions for bundle wallet #1... Submitting to Jito (retrying up to 40s)... Attempt #1: 3f9c0e... Launching snipe wave for 5 wallet(s)... Snipe wave complete: 5/5 landed successfully. Landed successfully.
When it finishes you see the Mint, Open Terminal → (after a successful launch, to trade the token from every wallet), View on Solscan →, and each snipe wallet's result: Landed, Failed on-chain or Timed out.
How execution works
| Phase | Detail |
|---|---|
| Bundle | Dev create+buy, up to 8 bundle buys (2 per transaction), and a 0.01 SOL tip (paid by the dev wallet), sent to 5 Jito regions at once |
| Retries | Re-sent with a fresh blockhash for up to 40 s until one attempt lands. Only one attempt can land |
| Snipe wave | Starts only if the create transaction landed without error. Each wallet sends buy + 0.005 SOL tip and retries for up to 20 s |
| Slippage | 5% on bundle and snipe buys |
| Platform fee | 1%, taken out of the amount you enter for each wallet (the amount is everything it spends). Each wallet pays its fee inside its own buy transaction, so nothing is charged for buys that don't land |
