CA (contract address)
The coin's address on Solana, its one true ID. Anyone can copy a name or a picture, nobody can copy the CA. Always check the CA, not the name.
Market cap (mcap)
Price times supply. A pump.fun coin has 1 billion tokens, so a price of $0.00001 is a $10k market cap. It says how big a coin is, not how much money you could actually sell for.
Liquidity
The money on the other side of your trade. With little liquidity, your sell pushes the price down a lot. On pump.fun the bonding curve is the liquidity; after graduation it sits in a PumpSwap pool.
Bonding curve
pump.fun's built-in market. No order book: a formula sets the price. Every buy raises it, every sell lowers it. A coin starts around a $3k market cap.
Graduation (migration)
When about 85 SOL has gone into the curve, the coin moves to PumpSwap and trades in a normal pool. Under 3% of active coins get there.
DEX, AMM, PumpSwap
A DEX is an exchange run by code, with no company holding your coins. An AMM is a pool of two tokens where the price comes from the ratio between them. PumpSwap is pump.fun's own AMM for graduated coins.
Slippage
How much worse than the shown price you accept. Set it too low and your trade fails; set it too high and bots can make you pay much more (see sandwich).
Priority fee
An extra fee so your transaction gets in faster. Fast apps add it for you. On small trades, fees eat a big share: see the cost sheet.
Holders and top 10
The wallets that hold the coin, and how much the 10 biggest hold together. The bonding curve and pools are not counted. A big top 10 means a few wallets can move the price hard, both ways.
Dev (creator)
The wallet that launched the coin. Many devs buy their own coin at launch and sell it into the first buyers. Check what the dev did before you buy: Dev check.
Rug (rug pull)
Insiders sell everything and the price collapses. On pump.fun nobody can pull the curve's money, so a rug means the dev and friends dump their bags into buyers.
Bundle
Several buys packed into the launch by wallets working together, often in the same block as the creation. They own a big part of the supply before anyone else can buy.
Sniper
A bot that buys in the first second, paying high fees to be first. You can't win that race by hand.
Whale
A wallet making big trades. On our live tape, any trade of 1 SOL or more is marked as a whale.
Volume
How much was traded. High volume looks exciting, but bots can fake it (see wash trading).
Ape, bag, bagholder
To ape is to buy fast without checking. Your bag is what you hold. A bagholder holds a coin that already fell.
Exit liquidity
The late buyers that insiders sell to. If you buy after a big pump on a bundled coin, you are probably their exit.
Narrative (meta)
The theme everyone is copying right now, like a word, an animal or a news story. Waves rise and die within hours: Narrative radar.
KOL and calls
A KOL is an influencer. A call is a post telling followers to buy. Many callers are paid, or bought before posting.
Paid profile and boost
On DexScreener anyone can pay to add a coin's info or to boost it in the trending list. It only means someone paid. See them on our launch log.
CTO (community takeover)
The dev left, and a group took over the coin's socials and promotion. Sometimes real, sometimes the same insiders with a new story.
Take profit, stop loss
Selling part when you are up, and selling when it falls to a level you chose before buying. Plans made before the trade beat feelings during it.
DYOR, NFA
Do your own research, not financial advice. Everyone says it; few do the first part.
Seed phrase
The 12 or 24 words that control your wallet. Whoever has them has your money. No real site, bot or support person ever needs them.
LARP
Pretending: a made-up story or an unproven claim, like a celebrity link or a giant profit, used to pump a coin or a reputation. Ask for the wallet.
Go deeper
Jito bundle
A group of transactions sent together through Jito, a Solana block service, and run in order in the same block. Launch bundles use it so the insider buys land right after the creation.
MEV and sandwich
A bot sees your trade coming, buys just before you and sells right after. You pay a worse price; they keep the difference. High slippage makes it easy for them.
Wash trading (volume bots)
Buying and selling to yourself to fake activity and climb trending lists. Lots of trades, few real people.
Insider cluster (split wallets)
One group spreads its supply over many fresh wallets so no single holder looks big. Bubblemaps shows them as linked bubbles.
FDV
Fully diluted value: price times the maximum supply. On pump.fun all tokens exist from the start, so FDV equals market cap. On other tokens it can be much bigger.
Mint and freeze authority
The right to create more tokens, or to freeze wallets. pump.fun's own program handles its coins, so this matters most for tokens made elsewhere: check them on RugCheck.
LP tokens
A receipt for money in a pool. Whoever holds the LP tokens can take that liquidity out; if they are burned, nobody can. Check this on tokens outside pump.fun.
Creator fees
pump.fun pays the coin's creator a small share of every trade (0.30% on the curve when we checked). Some devs earn from volume, not from the coin going up.
Mayhem mode
A pump.fun launch mode where an AI agent trades the coin and the supply is not the usual 1 billion. Trade counts and prices behave differently, so read them with care.
Honeypot
A token you can buy but not sell. Rare on pump.fun because pump.fun's own program runs the trades, but common with tokens made elsewhere.
Drainer
A site that empties your wallet once you sign its transaction. It often hides behind "claim", "verify" or "mint" buttons.
Address poisoning
Scammers send you a tiny amount from an address that looks almost like yours, hoping you copy it from your history later.
Wallet tracing
Following where SOL and tokens moved between wallets to find who is really behind a coin or a claim. Bubblemaps and Solscan do it for free.
