Best practices

These tips come from real problems users have hit. Follow them and most failures never happen.

Before you launch#

• Start small. The app has no test mode. Try your first launch with a tiny dev buy and few wallets. See Real funds & confirms.
• Leave SOL for fees in every wallet. Buying wallets need the buy amount plus network fees. The creator wallet needs the dev buy plus about 0.03 SOL for fees and rent.
• Keep the name and symbol short. pump.fun allows 32 bytes for the name and 10 for the symbol. Emoji and accented letters use more than one byte each.
• Read the totals. On Review & Deploy, check the line that adds up the dev buy and task buys. Create launches at once, with no extra confirm.
• Choose permanent options with care. On pump.fun, Holder Rewards cannot be switched back, and the Custom-pair fee (%) is final at launch.
• Warm up new wallets. Wallet warm-up gives new wallets a trading history with real trades on live pump.fun coins. It spends real SOL.
• Use Fund to fill many wallets. Sending straight from one wallet to many links them together on the chain. Fund wallets breaks that link. Vortex Disperse sends through in-between accounts. Mixer pays each wallet from an exchange, and the mixer service takes its own fee.

While you trade#

• Keep SOL in wallets you will sell from. A sale pays its network fee in SOL first. A wallet with no SOL cannot sell, even if it holds tokens.
• Run one task per token and wallet set. Two tasks on the same token with the same wallets can spend each other's tokens. Sales then fail or come out smaller than planned.
• Read the task Preview when there is one. Create the task without Start immediately, open Preview on its card, and press Start only when it looks right. Buy, Snipe, Migrate & Buy, Token Sender and Wallet warm-up have one.
• Count the platform fee. Every buy and sell pays it, including each trade of a volume task. See Platform fees & tiers.
• Turn on Confirm Sell all if you worry about pressing it by mistake. It is in Account settings → Trading.
• Plan your exit. One big sale moves the price a lot. The Ladder task sells in parts at several market-cap targets. The Trailing stop task sells when the market cap drops a set percent from its peak.
• On Robinhood Chain, wait for each transaction. A wallet there sends one transaction at a time.

When many launches fail at once#

If several launches fail together with the same error, the launchpad may be changing its program. Wait a few minutes before you try again. Do not keep pressing Create. See Troubleshooting.

Getting your money out#

• Check the address twice. A collection cannot be undone.
• Export keys before you delete wallets. After you delete a wallet, you cannot export its private key from the app any more. See Export a private key.
• Use Close out when you are done with a project. It sells what your wallets still hold and closes the empty token accounts to get the rent back. Then it collects the funds. It asks first. See Close out.

Keep your account safe#

• Never share a private key. After you copy one, paste it into your wallet and clear your clipboard.
• Plan password changes. A new password cancels all your API keys. See Sign in & accounts.
• Fund the wallet behind Copy deploy. Each copy is a real launch paid by Your deploy wallet. If it has no SOL, every copy fails. Failed copies still count toward Max per hour.
