Pump.fun Create & Bundle Buy

Pump.fun Create and Bundle Buy launches a token on the Pump.fun bonding curve and fires your opening buys from up to 16 wallets you control, all packed into one Jito bundle on Solana mainnet. The create transaction and the first buys ride together in the same submission, so the order of the launch is yours instead of a sniper’s.

When this tool fits

#when-this-tool-fits

• You run Pump.fun launches and want controlled, anti-snipe execution instead of a plain single-wallet create.
• You want the creator buy plus an initial buy spread across several wallets you own, all sequenced together.
• You already hold the private keys for every wallet you plan to include.
• You only need a simple single-wallet Pump.fun token. Use Pump.fun Create instead.
• You want to seed a real liquidity pool on a DEX rather than a bonding curve. Use Create LP instead.
• You do not control the keys for the wallets you would buy from. This tool requires raw keys for each bundle wallet, so it is the wrong fit for any wallet you cannot fully own.

Before you start

#before-you-start

• A connected wallet or a creator private key. Do not add the creator wallet to your bundle wallet list; its buy is folded into the create transaction and signed by your wallet, and the launch is blocked if the creator appears among the bundle rows.
• Token metadata ready: a name (up to 32 characters), a symbol (up to 10 characters), a description (up to 500 characters), and a token image uploaded as a file (PNG, JPG, GIF or WebP, up to 5MB). A banner and social links are optional.
• A private key for each bundle wallet (Base58, Base64, or array format). Each wallet’s balance has to cover its own buy amount plus the fixed 0.01 SOL the tool sets aside per wallet for rent, transaction fees, and a safety margin.
• SOL in the creator wallet for the creator buy, the platform fee, any Custom CA surcharge, the Jito tip, and a 0.01 SOL buffer. The app checks this balance before it builds anything.

Use only short-lived operational wallets; never enter a seed phrase or a long-term wallet key.

How to use it

#how-to-use-it

1. Configure token, media and creator buy

   Connect a wallet or supply the creator private key. Fill in the name, symbol, description and logo, plus a banner and links if you have them. Leave Creator buy on and enter how much SOL the creator wallet spends as the first buy, or turn it off.

2. Add bundle wallets and tip preset

   Click Import wallets and add up to 16 wallets by private key. Give each a buy amount by hand, or let Smart launch spread a total across them. Pick a Jito tip preset (Normal, Fast, or Turbo), or choose Custom and enter a SOL amount.

3. Review the preview and launch

   Check the live preview, the cost breakdown and the bundle summary until every wallet reads ready. Click Launch bundle and approve the create transaction in your wallet.

Key settings

#key-settings

• Name / symbol / description / image: Token metadata. Name up to 32 chars, symbol up to 10 chars (uppercased as you type), description up to 500 chars. Image is a required file upload (PNG, JPG, GIF or WebP, up to 5MB). Banner is optional.
• Website / X / Telegram / Discord: Optional social links, entered as full URLs.
• Creator buy amount (SOL): SOL the creator wallet spends as the first buy, inside the create transaction. On by default with 0.2 SOL prefilled; toggle it off for no creator buy.
• Bundle wallets: One to 16 wallets, each with a private key and a buy amount above zero. The tool reserves a fixed 0.01 SOL per wallet for rent and fees, so a wallet counts as funded when its balance covers the buy plus that reserve. Refresh rereads balances, and a wallet that appears twice is marked dup.
• Smart launch: Spreads a Total bundle buy across the wallets with one of four strategies (Organic, Even, Front-load, Stealth), a Variance that jitters each amount, and a Max per wallet share. No wallet is given more than its balance minus the reserve. Editing a wallet by hand switches to manual; Use smart launch switches back.
• Jito tip (speed): Normal, Fast (default), and Turbo bid 0.004, 0.012 and 0.032 SOL per bundle transaction. If ten times the live 99th-percentile landed tip is higher, the bid uses that instead, never above 0.25 SOL. Custom takes the whole tip as one SOL amount.
• Mayhem mode: Off by default. Turns on Pump.fun’s high-reward launch mode for the token, with more upside and more volatility.
• Custom CA: Off by default; launches use a randomly generated mint address. Turn it on to reserve a pre-grinded address ending in pump for a +0.1 SOL surcharge, subject to pool stock. You see the reserved address before you sign.

Fees and costs

#fees-and-costs

Caution

About fees. Every action has two costs: the Solana network fee paid to validators, and the J Tools platform fee. The platform fee always shows in the app before you confirm, and nothing is charged until you sign. Fees can change over time, so trust the in-app summary rather than a number you saw once.

Cost	Amount
J Tools platform fee	0.05 SOL base + tiered per-wallet fee; live total shown before launch
Solana network fee	Paid to validators during the transaction; shown in the live summary.
Rent and transaction value	Shown separately when required; not part of the platform fee.

Fees and costs

#fees-and-costs-1

• Solana network fee. The base per-signature fee for each transaction in the bundle. Inside a bundle the Jito tip, not a compute-unit price, decides placement.
• Account rent. Creating the mint and the associated token accounts requires a small SOL deposit to keep those accounts alive on-chain. Rent for accounts you fund is recoverable if those accounts are later closed; the network does not burn it.
• Jito tip. Paid from the creator wallet inside the create transaction. A preset tip scales with the number of transactions in the bundle. If the bundle lands, the tip is spent and is not refundable. If a bundle never lands, that tip was not paid.
• Platform fee. The 0.05 SOL base for the launch, shown in the app before you sign. It is attached on-chain in the create transaction.
• Per-wallet service fee. Tiered by how many bundle wallets you include: 0.05 SOL per wallet for 1 to 4 wallets, 0.04 SOL for 5 to 8, and 0.035 SOL for 9 or more. With 16 wallets the platform fee is 0.05 + 16 × 0.035 = 0.61 SOL. The cost breakdown shows base and per-wallet fee as one line.
• Your buy amounts. The actual SOL the creator and each bundle wallet spend buying the token. These are not a fee; they are your position.

How it works

One Jito bundle is built live total shown before you sign

1. 1 Preflight checks every wallet's balance buy + 0.01 SOL
2. 2 Optional: reserved mint ending in pump …pump
3. 3 Create tx includes the creator buy 6EF8rrect…EwF6P
4. 4 Bundle wallets sign their buys locally ≤ 16 wallets
5. 5 About four buys packed per transaction ≤ 5 tx / bundle
6. 6 Platform fee and Jito tip attached Jito tip
7. 7 Bundle sent to the Jito Block Engine Jito Block Engine

Common issues

#common-issues

• Creator wallet is in the bundle list. The connected creator wallet must not be one of the bundle wallets; its buy already rides inside the create transaction. Remove it from the list and try again.
• A wallet is underfunded. Each wallet needs its buy amount plus the fixed 0.01 SOL reserve. Right before launch the app rereads every balance from the chain and stops, naming the first short wallet, before any tip is spent. Top up the wallet and run again.
• Total buy over the cap. The creator buy plus every bundle buy cannot exceed 85 SOL in one launch. That is where the Pump.fun bonding curve completes, and a bundle that filled it mid-execution would revert as a whole. Lower the amounts or split the launch.
• Bundle does not fit. A Jito bundle holds at most 5 transactions and the tool packs about four buys into each. If your wallet list cannot be packed into that, the launch stops before any signature rather than silently dropping a wallet. The message says how many wallets fit; remove the rest, or turn off the creator buy, and try again.
• Bundle did not land. On a rate-limit or auction rejection, the bundle may not get into a block. A higher Jito tip improves your odds. If the tip was already paid for a landed bundle, it is not refundable.
• Another launch in progress. One launch runs per wallet, and per browser across tabs. Wait for the first one to finish before you start the next.
• Custom CA unavailable. The pump-suffix address pool can run out of stock, which disables the toggle. Wait for it to refill, or launch with the default randomly generated mint.
• Wallet warning at signing. A wallet prompt that flags a transaction is a signing-code or balance issue on the specific launch, never a blocklist on the J Tools domain. Check the underfunded case first.

Practical tips

#practical-tips

• Plan your wallet spread before you fund. Decide the buy size per wallet first, then fund each wallet with its buy amount plus the 0.01 SOL reserve plus a margin. Funding after you have set the buys is how rows fail preflight.
• Do not grind your own mint key. There is no field for supplying one. If you want a pump-suffix address, Custom CA is the only route: it reserves a pre-grinded mint from the pool for +0.1 SOL and shows the address before you sign.
• Start with a preset tip. Raise the Jito tip only when you are launching into heavy competition; the presets already rise on their own when the tip market is hot. A landed bundle spends the tip whether it needed the boost or not, so an oversized tip on a quiet network is money spent for nothing.

Note

About wallet warnings. Some tools bundle several instructions into one transaction, for example creating a token and its metadata together. Phantom can show a caution banner for these transactions, and where the tool tells you to expect one, it does not mean something is wrong. Read what you are signing, then approve if it matches what you set up. If a warning appears that the tool did not mention, decline it and tell support.

Tip

J Tools is non-custodial. We never store your wallet’s private keys and never ask for your seed phrase. Every transaction you approve in a connected wallet is signed inside that wallet, and its key never reaches our servers. A few multi-wallet tools do let you paste private keys for throwaway hot wallets, which stay in your browser tab and sign there. Holder Booster is the one tool that hands a key to our worker: the fresh distributor wallet it creates for each run, sent encrypted. Never paste a key tied to long-term holdings, and if a page ever asks for your seed phrase, stop and close it.
