Pump.fun Create

Pump.fun Create launches a coin on the Pump.fun bonding curve from a single wallet, in one screen. You fill in the name, ticker, and logo, the app uploads your metadata and builds the on-chain create instruction, and you sign it in your own browser wallet.

When this tool fits

#when-this-tool-fits

• You want to launch a coin on Pump.fun from a single wallet, without juggling the official UI.
• You want a pump-suffix mint and the option to take your own first bag in the same transaction as the create.
• You want to see the full cost, including your buy and the priority fee, checked against your balance before you commit.

Before you start

#before-you-start

• A connected wallet (how to connect) or an imported private key, with enough SOL for the platform fee, any SOL creator buy, the Solana priority fee, and a small network buffer of 0.01 SOL on top.
• A token logo image, up to 5 MB. PNG, GIF, JPG, JPEG, or WEBP all work. A 1000x1000 square or larger looks best.

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. Fill basics and media

   Connect a wallet in the top bar. Enter the name and ticker, add a short description if you want one, and upload the logo. A banner and your website, X, Telegram, or Discord links are optional.

2. Pick features and speed

   Decide whether to buy on launch and how much, then pick a Speed preset. Turn on any extras you want: your custom token address, Mayhem mode, a USDC launch, or cashback for traders.

3. Review and launch

   Check the live preview card and the cost breakdown against your wallet balance. Click Pump launch and approve the transaction in your wallet.

Key settings

#key-settings

• Name: Token display name. Required, up to 32 characters.
• Ticker: Required, up to 10 characters. It is uppercased as you type.
• Description: Optional blurb stored in the metadata. Up to 500 characters.
• Logo: Required, up to 5 MB. A 1000x1000 square or larger is recommended.
• Banner: Optional banner image, up to 5 MB. 1500x500 (3:1) looks best.
• Website / X / Telegram / Discord: Optional social links. Use full http or https URLs. Saved into the metadata.
• Buy on launch: On by default. Your wallet buys the first bag in the same transaction as the create, so nobody can buy in between. A SOL buy has to be at least 0.02 SOL, Pump.fun’s own program-level floor.
• Buy amount: The size of that first buy, prefilled with 0.1. Must be above zero when the buy is on. For a SOL buy, the form shows an estimate of the tokens you get.
• Speed: The compute-unit price that sets landing speed. Presets are Normal, Fast (default), and Turbo, plus a Custom budget in SOL.
• Your Custom Token Address: Reserves and shows the exact pump-suffix mint before you sign, for an extra 0.1 SOL on top of the platform fee. Every launch already gets a pump suffix without this.
• Mayhem mode: Pump.fun’s launch mode where, for the first 24 hours, the bonding curve reacts harder to every trade and the price swings wider.
• Launch with USDC instead of SOL: Puts the coin on Pump.fun’s USDC bonding curve. A buy on launch is then paid from your USDC balance, and the 0.02 SOL floor does not apply.
• Cashback for traders: Part of the trading fee goes back to the traders who buy and sell your coin. Pump.fun handles the routing.

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	0.05–0.15 SOL
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 and priority fee. The base signature fee is a few thousand lamports, a tiny fraction of a cent. The priority fee is set by your Speed preset and is what actually decides how fast the transaction lands when the network is busy. The cost breakdown shows it on its own line. Both go to Solana validators, not to J Tools.
• Account rent. Creating a token and its accounts means putting down rent: a small SOL deposit Solana holds while the accounts exist. This is refundable in the sense that rent for accounts you later close comes back to you. The bonding curve and mint accounts stay open for the life of the token.
• Pump.fun’s own costs. The protocol charges its creation and trading costs, which go to Pump.fun, not to J Tools.
• Your creator buy. If you turn on buy-on-launch, that amount is your own opening bag. It is not a fee; it buys you tokens out of the curve.
• The J Tools platform fee. A flat 0.05 SOL, plus 0.1 SOL when you reserve your custom token address, attached as visible SOL transfers that you sign with the launch and shown up front. J Tools takes no percentage of your buy. For the current number, see the fee schedule.

Before you sign

#before-you-sign

Check the live summary before signing. The app is the current source of truth for amount, fee and route.

Common issues

#common-issues

• Initial buy too small. A SOL buy has to be at least 0.02 SOL. Raise the amount, switch the launch to USDC, or turn the buy off.
• Address pool empty. The pump-suffix mint comes from a server pool. If it runs dry the launch stops with VANITY_CA_POOL_EMPTY. Try again shortly.
• Logo missing. The launch will not start without a logo. Upload one; the banner is the only optional image.
• Image too large. The logo and banner uploads are refused above 5 MB each. Compress or resize and re-upload.
• Not enough USDC. On a USDC launch the buy comes from your USDC balance. Add USDC or lower the buy amount.
• Transaction did not land. On a congested network a Normal-speed launch can expire before it confirms. Bump the Speed preset to Fast or Turbo and retry.
• Launch sent, result unknown. If the connection drops after the transaction goes out, the app shows its signature instead of a result. Check that signature on an explorer before you launch again, or you could pay the fee twice for the same token.

Practical tips

#practical-tips

• Open with a buy to take the first bag. Your buy lands in the same transaction as the create, so the opening price goes to you rather than to whoever finds the token first. Size it deliberately; a larger opening buy moves the curve more before anyone else can act.
• Tune speed to the moment. Turbo earns its priority fee during a busy launch window. On a quiet network, Normal lands fine and costs less.
• You keep no authorities, by design. A standard Pump.fun launch revokes the mint authority at creation, so nobody, including you, can ever mint more supply. It does not leave the metadata update authority with your wallet either, which means Update metadata and Make immutable only work on tokens where your wallet actually holds that authority.

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.
