Memecoin launch glossary

Launching

A launch creates a coin and puts it up for trading in one step. These are the words for what happens then.

• Launchpad. A service where anyone can create a coin and have it trade at once, with no code and no pool to fund. pump.fun and pons are launchpads.
• Bonding curve. A contract that sells a new coin at a price that rises as more is bought and falls as it's sold. It's the coin's only market until it graduates.
• Graduation. The moment a coin's bonding curve is full and it moves to an exchange pool: at about 85 SOL on pump.fun, at 4.2 ETH on pons. Also called bonding or migrating.
• Dev. The wallet that created the coin, or the person behind it.
• Dev buy. The creator's own first purchase, made in the same transaction that creates the coin, so it's the first buy at the starting price.
• Supply. How many of the coin exist. On pump.fun and pons it's fixed at 1 billion.
• Contract address (CA). The coin's unique address on the chain. Names and pictures can be copied; the address can't.
• Vamp. A new coin that copies a live coin's name, ticker and picture. See What is a vamp coin?
• Mayhem mode. A pump.fun launch option in which pump.fun's AI agent trades the coin for its first 24 hours.

Wallets and bundles

Launching from more than one wallet has its own vocabulary.

• Bundle. On Solana, a group of transactions sent to land together in one block, in order: all or none.
• Bundle launch. Creating a coin and buying it from several of your own wallets in that first block. See pump.fun bundle launches.
• Bundler. A tool that builds bundle launches. See Solana bundler and Solana bundlers compared.
• Bundle wallet. One of the extra wallets that buys in a bundle launch.
• Block 0. The block a coin is created in. A Block 0 launch lands every wallet's buy there.
• Snipe. Buying a coin in its very first moments. On pons, memetools's Snipe launch has your own wallets do it the instant the launch confirms.
• Sniper. A wallet or bot that snipes.
• Bundle checker. A tool that shows how much of a coin was bought in its first block, and by which wallets.
• Funder. The wallet that sends SOL or ETH to your bundle wallets.
• Sweep. Sending what's left in the bundle wallets back to the funder.
• Sell all. Selling a coin from several wallets at once.

Fees

Every trade pays the launchpad, often the coin's creator, the network, and any tool used to send it.

• Trading fee. What the launchpad takes from each buy and sell: 1.25% on pump.fun's curve, about 1% on pons.
• Creator fee. The part of pump.fun's fee paid to the coin's creator: 0.30% of trades on the curve. See pump.fun creator fees.
• Creator tax. On pons, an extra 0–10% of every trade that the creator sets at launch and receives.
• Holder rewards. A pump.fun option that pays the creator fee to the coin's holders instead of its creator.
• Anti-snipe tax. On pons, a tax on buys in a launch's first seconds: 99% at the start, falling to zero over five seconds.
• Gas. The fee a network charges to process a transaction. Solana's is paid in SOL, Robinhood Chain's in ETH.
• Priority fee. An optional extra paid to a network to have a transaction processed sooner.
• Tip. On Solana, a payment that gets a bundle carried into a block.
• Rent. The small SOL deposit Solana requires for every account, including a wallet's account for each coin it holds.

Trading and risk

A few more words that come up once a coin is live.

• Market cap. A coin's price times its supply. It says nothing about how much could actually be sold at that price.
• Slippage. How far the price may move against you between asking for a trade and it happening. A trade outside your limit fails.
• Community takeover (CTO). When holders take over a coin its creator has abandoned. On pump.fun it can change who receives the creator fee.
• Rug pull. When the people behind a coin sell everything they hold, or drain its liquidity, and the price collapses.
• Non-custodial. Software that never holds your keys or funds. You sign every transaction yourself, and nobody else can move your coins or restore a lost key.

Memecoins are highly speculative, and most lose nearly all their value. Nothing here is financial advice.
