What is a vamp in crypto?
A vamp is a coin that feeds on another coin's success. Usually it's a copycat: the same name, ticker and picture, launched minutes after the original takes off.

On pump.fun, vamping also means a creator moving a coin's fees to their own wallet once the volume shows up. Checking the CA catches the copycat. Locking the fees at launch stops the switch.
Three things people mean by vamp
| Meaning | What happens | Where you'll hear it |
|---|---|---|
| Copycat | A new coin copies a moving coin's name, ticker and picture to catch its buyers. | Meme coin trading, pump.fun |
| Fee switch | A creator promises a coin's fees to holders or a cause, waits for the volume, then points them at their own wallet. | pump.fun |
| Vampire attack | A project lures users, and their money, away from a rival with bigger rewards, as SushiSwap did to Uniswap in 2020. | DeFi |
Meme coin traders mostly mean the first. "That's a vamp" means "that's a copy of the coin you're looking for". It's a different scam from a rug pull, where a coin's own creators cash out.
Why copycats work
On the stock market, an exchange hands out tickers, so there's one AAPL. On pump.fun, nobody hands out names. Anyone can launch a coin with any name, ticker and picture in under a minute, on its own bonding curve, so when a coin takes off, copies follow within minutes.
Copies work because people search by name. Type a hot coin's name into pump.fun or a trading app, and you'll see several coins with the same name and picture. The one people tap first isn't always the real one. The only thing a copy can't copy is the CA.
Spot the vamp
Three rounds, each with a trick vamps use and the check that beats it.
notrandom.fun pinned this on X. Which of these search results is the real $NTRNDM?
NTRNDMqQSiwEC2jJs3wJiZS6bpGYQJtMNQJgiX3WyV6
Right. Its CA matches the pinned post, NTRN to WyV6. It's also the only one that has graduated: copies are usually minutes old.
That's a vamp. Same name, same picture, but its CA doesn't match the pinned post's NTRN…WyV6. Watch the near miss: NTRw copies the first three letters.
A reply under the pinned post says the coin moved. Is this the same coin?

Right. Only the ends match, so it's a different coin. And a pump.fun coin never moves: it keeps its CA for life, graduation included. "New CA" means a new coin.
That's a vamp. Only the ends match. The pinned CA goes on NTRNDMqQ; this one goes NTRNgZBe. Lookalikes copy the ends people check. And a pump.fun coin never moves: "new CA" means a new coin.
This $NTRNDM coin on pump.fun says notrandom.fun's wallet created it. Can you trust that label?
7vQd…nTRd, the wallet notrandom.fun posted
Right. Whoever launches a pump.fun coin can name any wallet as its creator, without that wallet's say. The CA from the source is the check nobody can fake.
Not on its own. Whoever launches a pump.fun coin can name any wallet as its creator, without that wallet's say. A vamp can show notrandom.fun's real wallet. The CA from the source is the check nobody can fake.
How to check a coin before you buy
- Get the CA from the source. The project's X bio, pinned post or website. Never from a reply, a DM or a search result.
- Paste the CA, don't search the name. Paste it into pump.fun or your trading app, and you get one coin, not a list.
- Compare the start, the end and a chunk of the middle. Or paste both into our CA reader.
- Check the age and the holders. A copy is usually minutes old, with a handful of holders.
- Ignore "new CA" announcements. A pump.fun coin keeps its CA for life, graduation included.
- Don't trust the creator label alone. Whoever launches a pump.fun coin chooses the wallet it shows as creator.
The fee switch
Every trade on a pump.fun coin pays its creator a fee, called creator rewards. A fee vamp launches with those fees promised somewhere generous: to holders, to a team, to a cause. It waits for the volume, then points the fees at its own wallet. Since March 2026, pump.fun lets a creator change who gets a coin's fees once after launch, and once is all a vamp needs.
The fix is to lock who gets the fees from the start. On notrandom.fun's Share 10% plan, your launch sets who gets the fees in the same transaction that creates the coin, using up the one change pump.fun allows. From the first trade, neither you nor we can switch it. Only pump.fun can still reassign a coin's fees, when its community takes it over.
How creators make a coin hard to vamp
- Put a word in the CA. Holders learn what the real CA reads, and a vamp's random one gives it away. A word at both ends gives them two to check. Here's how to get a custom CA on pump.fun.
- Launch first, announce second. A name you post before launch is a name a vamp can launch first.
- Pin the CA everywhere, and say what it reads. Starts
DeEz, endsnuts. - Lock the fees at launch. So nobody can promise holders one thing and switch to another.
The full playbook, with Share 10% and our CA locks: how notrandom.fun stops vamps. Already live? Lock your CA's ends, so nobody can order a lookalike from us.
The best defense is a CA your holders recognize at a glance. Get a CA that starts with your word, launch it on pump.fun with one wallet approval, and tell your holders what it reads. On your first buys, set your slippage with care, and know what your coin is paired with.
Questions
What does vamp mean in crypto?
A coin that feeds on another. Usually a copycat with the same name, ticker and picture; on pump.fun, also a creator switching a coin's fees to their own wallet. In DeFi, a vampire attack is a rival luring users away with bigger rewards.
How do I know if a coin is a vamp?
Compare its CA with the one the project posts on its own X or website. A copy has the same name and picture but a different CA, and it's usually minutes old.
Is buying a vamp the same as buying the real coin?
No. A vamp is a separate coin with its own price and its own holders. Its chart has nothing to do with the original's.
Can a coin change its CA?
No. A pump.fun coin keeps its CA for life, through graduation. "New CA" means a new coin, and it's a favorite line of vamps.
How do creators protect a coin from vamps?
Put a word in the CA, launch before announcing, pin the CA, and lock the fee split at launch. A notrandom.fun launch on Share 10% takes care of the first and the last.
