Pump.fun Troubleshooting: Failed Trades, Missing Tokens and Code Issues

Why is my Pump.fun transaction failing?

A failed transaction on Pump.fun almost always comes down to one of four causes: not enough SOL for fees, a slippage limit that the price moved past, a congested network, or a transaction that expired before it landed. None of them means your funds are lost. When a Solana transaction fails, the trade does not happen and your balance stays where it was, apart from a small network fee in some cases.

This guide works through the most common problems in order of how often we see them. If you are new, the how to use Pump.fun guide explains the screens referred to here.

Quick diagnosis table

Symptom	Most likely cause	First fix
“Transaction failed” on a buy	Slippage too low in a fast market	Retry once with slightly higher slippage
Sell will not go through	Not enough SOL for network fees	Add a small amount of SOL
Trade pending for a long time	Network congestion	Wait, then check a block explorer before retrying
Bought, but token not showing	Wallet has not refreshed or hides new tokens	Refresh; check hidden tokens
Platform fee shows 0.45%	Referral code not applied to this wallet	See the referral section below
Wallet will not connect	Extension locked or wrong network	Unlock wallet, reload the page

Not enough SOL for fees

Every Solana transaction needs a little SOL for the network fee, even when you are selling a token. A very common trap is spending all your SOL on a buy and then being unable to sell. The fix is simple: send or buy a small amount of SOL into the wallet, then retry. Going forward, always leave some SOL unspent.

Slippage errors

Slippage is the maximum price change you accept before a trade is cancelled. On a bonding curve, prices can move a lot in seconds. If the price moves more than your setting allows, the trade fails to protect you.

• Retry once, raising slippage a little rather than a lot.
• On a coin moving violently, consider not trading at all. Very high slippage can fill you at a terrible price.
• Remember that larger orders move the curve further, so reducing your order size also helps.

Congestion and pending transactions

On busy days the Solana network can be slow. A transaction may sit pending, then fail or expire. Before you retry, look up your wallet address on a Solana block explorer to see whether the first attempt went through. Retrying blindly can leave you with two buys instead of one. Some interfaces let you add a priority fee; a small one can help in busy periods, but it is an extra cost.

Tokens not showing after a buy

If the trade succeeded on a block explorer, the tokens are in your wallet. Wallets sometimes take time to index new tokens, and many hide unknown tokens by default as spam protection. Refresh the wallet, look for a hidden or unverified tokens section, or search for the coin’s contract address. Never “fix” this by following a link someone sends you. If you use Phantom, our Phantom guide shows where hidden tokens live.

Wallet connection problems

If your wallet will not connect to the web app, unlock the wallet first, then reload the page. Check that the wallet is on Solana. Disconnect Pump.fun from the wallet’s list of connected sites and connect again. Browser extensions that block scripts can also interfere. Most importantly, confirm the address bar reads pump.fun: a lookalike site that “will not connect properly” may be trying to get you to sign something else.

The referral code did not apply

Check the platform fee line on your next trade confirmation. According to Pump.fun’s fees page, it reads 0.40% when a referral code is applied to your wallet and 0.45% when it is not.

If you are on 0.45%, work through these questions:

1. Did you confirm the code in the app? Pump.fun’s Deposit Match Program Terms say opening a link does not apply a code by itself. It must be entered or confirmed in the app.
2. Did you apply it before your first purchase and within 24 hours? Those are the conditions for the deposit reward. A late code does not qualify for the reward.
3. Are you trading from the same wallet? The code is tied to the wallet that applied it. A different wallet starts without it.
4. Did you already use another code? A referral code cannot be changed or replaced once applied.

If you have not yet made your first purchase, open pump.fun/join/NEWUSER50 and confirm NEWUSER50 now. It gives 10% off trading fees and the chance of up to $50 on your first deposit. The Pump.fun referral code page has the short checklist, and our referral code explainer covers every rule.

The deposit reward has not arrived

Rewards are not paid at the moment you deposit. Pump.fun reviews deposits first. Under a lump-sum offer, the terms say it aims to decide within two days. Under an installment offer, rewards are released over your first five qualifying trading days in the mobile app, within ten days of the deposit. Withdrawing the purchased assets before the reward is credited forfeits it. Rewards can also be declined at Pump.fun’s discretion, and the program can end when its budget runs out. If you think something went wrong, use the support link on the official homepage.

When to contact support, and how

Use only the support link on the official pump.fun homepage. Scammers watch for people asking for help in public and reply with fake support accounts, “wallet validation” links or requests for your recovery phrase. No genuine support agent will ever need your phrase or ask you to sign a transaction to “fix” an account. Our safety guide explains the common recovery scams.
