How to avoid rug pulls on pump.fun
You cannot avoid every rug pull on pump.fun, but you can avoid most of the obvious ones by checking who holds the supply before you buy, and limit the damage from the rest with position size, a market cap floor and a stop.
How do you avoid rug pulls on pump.fun? Look at who holds the supply before you buy, skip the coins where a few wallets can dump on everyone else, and size every position so a rug that slips through is a small loss rather than a big one. No checklist catches everything, so the second half of the job (limiting damage) matters as much as the first.
What a rug pull looks like on pump.fun
A rug pull is when the people behind a token take the buyers' money and leave them holding something nearly worthless. On many chains that means the creator pulling the liquidity from the pool. On a standard pump.fun coin, that version is blocked by design:
- No new supply. pump.fun sets a coin's mint authority to null at creation, so nobody can print more tokens.
- No pulling the pool. pump.fun's help center says that when a coin migrates to PumpSwap, the liquidity pool tokens are locked and burned, and "the dev cannot remove liquidity to zero".
The rug that is left is the dump. The creator, or a group of wallets that bought early, sells a large share of the supply into the people buying the chart. The price collapses in a few transactions. The pool is still there. It just has much less in it. That is why every red flag below is about who holds the supply.
How common is it? A May 2025 report by Solidus Labs classified 98.6% of the tokens launched on pump.fun as rug pulls or pump-and-dump schemes. pump.fun disputed it, with a spokesperson saying most memecoins "are worth little in the long run. That's precisely the point." Both sides agree on the practical part: most coins there go to zero. More in how pump.fun works.
The on-chain red flags checklist
The most reliable way to spot a pump.fun rug pull is to read the holder list, because every red flag is public on-chain before you buy.
| Red flag | What to look for | Why it matters |
|---|---|---|
| Big dev bag | The creator wallet holds a large share of supply | One wallet can end the chart in one sell |
| Dev already selling | The creator wallet has sold, or moved tokens to other wallets | Moving tokens first hides the size of the exit |
| Bundled launch | Many wallets bought in the first block or seconds, often similar sizes | Looks like many buyers, is often one |
| Fresh, linked wallets | Top holders created recently and funded from the same source | A cluster that will sell together |
| Top holder concentration | A handful of wallets (excluding the curve or pool) hold much of the supply | Few sellers can drain many buyers |
| No or copied socials | No site, no X account, or ones borrowed from another coin | Nobody plans to be around next week |
| Authorities (off pump.fun) | Active mint or freeze authority on a token from another launcher | Printable supply, or tokens that can be frozen |
Bundles and coordinated groups have their own page: pump.fun bundles and cabals. The creator's wallet is covered in the pump.fun dev wallet.
What a pump.fun rug checker actually checks
A rug checker is a tool that scores a token's structural risks from on-chain data, and it is good at the checks that are mechanical. RugCheck, a widely used checker on Solana, looks at:
- Mint authority. Whether someone can still create new tokens.
- Freeze authority. Whether someone can freeze holders' token accounts, which is how many Solana honeypots work.
- Holder distribution. Whether a few addresses hold a disproportionate share.
- Liquidity. How much is locked, until when, and with which locker.
- Insider networks. Links between top holder wallets that suggest a coordinated group.
Trading terminals do some of this in their filters too. Axiom's documentation, for example, lists filters for dev holding, top 10 holders, snipers, insiders and bundles.
What a checker cannot do is read intent. A standard pump.fun coin passes the authority checks by default, so a clean score says little about whether its holders are about to sell. Use the score to rule coins out, never to rule them in.
How to limit the damage when a rug gets through
You limit rug damage with rules set before the trade, because a dump takes seconds and a decision takes longer. If you copy wallets with copypump, these settings do that job:
- Size. A fixed amount per trade, or a percentage of the trader with a max per trade. The single most effective rug defence is a position you can lose in full without caring much.
- Market cap band. A minimum ($100k, $500k, $1m or custom) skips buys in the tiniest coins, which, as the docs put it, run harder and rug harder. The band never blocks an exit.
- Max impact. Skips a buy if your own order would move the pool more than your limit, which keeps you out of the thinnest pools.
- First buys only. Copies only the trader's very first entry into a token, not the adds into a chart that is already running.
- Stop loss. -25%, -50%, -80% or custom from your entry. copypump sells what is left when it hits. See stop losses on pump.fun.
- Mirrored exits. When the wallet you copy sells, you sell the same fraction. A good wallet that gets out of a dumping coin takes you with it.
- No re-buy after a sell. On by default for 24 hours, so you do not buy back into a coin you just left behind another trader.
A starting profile for all of these is in the best copy trade settings for pump.fun.
How to avoid rug pulls on pump.fun: a two-minute routine
If you buy by hand rather than copy, run the same checks every time, in the same order:
- Open the holder list. Note the creator's share and the top 10 excluding the curve or pool.
- Look at the first minute of trades. Many similar buys in the same block is a bundle.
- Click two or three top holders. New wallets funded from the same place are one holder.
- Run the address through a rug checker for authorities and linked wallets.
- Check the socials exist and belong to this coin.
- Decide your size and your stop before you buy, not after.
If a coin fails any of the first three, skipping it costs you nothing but a missed chart. There will be another one in a minute.
Frequently asked
How do you avoid rug pulls on pump.fun?
Check the holder list before you buy: how much the creator holds and whether it has sold, whether the early supply sits in many fresh wallets bought in the same moment, and how concentrated the top holders are. Then keep each position small and use a stop loss, because some rugs pass every check.
Can a pump.fun dev pull the liquidity?
Not on a standard coin. Mint authority is set to null at creation, and pump.fun says that when a coin migrates to PumpSwap the liquidity pool tokens are locked and burned. The rug that remains is a dump: the dev or a group of wallets selling a large share of supply into buyers.
What does a pump.fun rug checker check?
Tools like RugCheck look at mint and freeze authority, how supply is spread across top holders, whether liquidity is locked, and links between top holder wallets. They catch structural risks well, but a clean score does not mean holders will not sell.
How do you spot a rug pull on Solana?
The common signs are one wallet or a cluster of related wallets holding a large share of supply, many wallets funded from the same source buying in the first seconds, a creator selling early, an active mint or freeze authority on tokens launched outside pump.fun, and socials that are missing or copied.
What share of pump.fun tokens are rug pulls?
A May 2025 Solidus Labs report classified 98.6% of pump.fun tokens as rug pulls or pump-and-dumps, a finding pump.fun disputed, saying most memecoins are meant to be worth little. Either way, most coins launched there lose nearly all their value.
Let the rules say no for you.
copypump copies a wallet's buys and sells at your size, inside a market cap band, a max impact and a stop loss you set once.
