pump.fun vs Clanker vs four.meme vs Zora vs launch races: how the five meme coin launch models actually differ

Meme coin launchpads look alike on the surface: a form, a picture, a button. Underneath, the five models in use today make different choices about when a DEX pool exists, who picks the chain, what the creator pays with and earns, and how exposed the first minute is to bots. This comparison covers pump.fun on Solana, four.meme on BNB Chain, Clanker and Zora on Base, and the four-chain launch race run on sasa, using only what each platform documents about its own mechanics and leaving out volume claims and fee percentages that change. If you want the general background first, how meme coin launchpads work covers the shared machinery; pump.fun alternatives covers why people look beyond Solana.

The five models in one paragraph each

• pump.fun (Solana): the coin starts on a bonding curve contract with a per-trade fee. Buys fill the curve; when it reaches its target, the coin graduates to PumpSwap, pump.fun's own DEX, and the launchpad handles the pool's liquidity under its own rules. Creators need a Solana wallet with SOL. pump.fun's documentation states its current fees and any creator revenue share; check it on the day.
• four.meme (BNB Chain): the same shape on BNB Chain. The coin starts on a bonding curve, trades there with a per-trade fee, and graduates to a PancakeSwap pool when the curve fills. Creators and buyers pay in BNB. The BNB Chain launchpads guide covers it alongside direct PancakeSwap launches.
• Clanker (Base): no curve. A creator requests a token, through the Clanker agent on Farcaster or its web app, and the token is deployed straight into a Uniswap v4 ETH pool on Base, with the liquidity position kept by the factory rather than the creator. The pool exists from the first block, so bots and DexScreener see it at once, and Clanker's documentation describes the share of pool fees it pays the creator.
• Zora (Base): a content model. Posts become coins, each with a Uniswap pool on Base, and the creator of the content earns from trading on it. The coin is tied to a piece of media rather than launched as a standalone ticker, and discovery happens inside Zora's feed as well as on DEX trackers.
• Launch race: no curve and no single chain. The coin deploys to the same address on Base, BNB Chain, Robinhood Chain and Arc with a native pool on each, about $3,000 of combined starting market cap and a creator first buy on each chain in USDC (from $5 per chain); after five minutes the chain with the most buying keeps everything, less a 2% hand-over fee on the losing pools' money, in one locked pool and holders on the other chains are moved over automatically. How the 5-minute launch race works has the full sequence.

When does a real DEX pool exist?

This is the difference that drives most of the others. On pump.fun and four.meme the coin spends its first phase on a curve: a contract with a formula, no outside liquidity provider and no DEX pair. It is not on Uniswap or PancakeSwap, DexScreener shows it as a launchpad coin rather than a pair, and trading bots that watch DEX factories do not see it until graduation. Graduation can take minutes, hours or never. Uniswap's documentation at docs.uniswap.org describes the pool model the direct routes launch into. On Clanker and Zora the DEX pool exists from the first block, which means the coin is on every tracker and in every bot's feed immediately. A launch race sits between: four DEX pools exist from the first block on their respective chains, and after five minutes they become one. Trackers and bots see the coin at launch, and after consolidation they see a single native pair on the winning chain.

Who picks the chain?

On four of the five, the creator does, by choosing the launchpad. pump.fun means Solana, four.meme means BNB Chain, Clanker and Zora mean Base. The choice is made before any buyer has voted and is permanent; a coin that would have found its crowd on another chain stays where it was born, or is copied there by someone else. In a race, the creator does not choose. Buyers on four chains compete for five minutes and the chain with the most buying keeps the coin. Best chains to launch a meme coin is the guide for creators who have to choose; the race is the option for creators who would rather not.

What the creator pays and pays with

• pump.fun: whatever creation cost its docs state, paid in SOL. The creator needs a Solana wallet with SOL.
• four.meme: a creation cost in BNB, plus any first buy in BNB.
• Clanker: a token request through the agent or app, with the deployment handled by Clanker; the creator needs a Base wallet to receive fees and ETH to trade.
• Zora: posting is the launch; the creator needs a Zora account and a Base wallet.
• sasa: a first buy on each chain in USDC (from $5 per chain) plus each chain's network fee of a few cents. sasa deploys the coin and opens the four pools, and with a sasa account the network fees come out of the USDC balance, so the creator never holds ETH, BNB or any gas token.

What the creator earns

All five pay creators from trading, which is a recent and welcome convergence; a few years ago the only creator income was selling the allocation. The sources differ. Curve launchpads pay from fees on the curve, on the graduated pool or both, under terms set by the launchpad. Clanker pays the creator a share of the Uniswap pool's fees, on terms its documentation states. Zora pays the content creator from trading on their coin. A launch race pays the creator 30% of every trading fee on the winning pool, forever, or applies the same share to buyback and burn if the creator chose that at launch. For a creator comparing, the questions are the ones from the creator fee guide: what percentage of which fee, starting when, for how long, and whether it depends on graduating.

Liquidity: locked, burned or neither

pump.fun's and four.meme's graduated pools follow each launchpad's documented liquidity handling. Clanker keeps the Uniswap position rather than handing it to the creator. Zora coins trade on pools created by the protocol. A race's winning pool is locked forever by the protocol, so neither the creator nor the platform can remove it. In every case, verify on the chain rather than on the website: how to check if liquidity is locked walks through finding the position holder on Basescan or BscScan. Remember that a lock protects against the pool being pulled, not against holders selling into it.

The first minute: bots and fairness

Each model has a characteristic first minute. On a direct pool launch (Clanker, Zora), sniper bots that watch Uniswap's factory can buy in the pool's first block; the first buyers list on such coins often shows several automated buys before any human. On a curve launch (pump.fun, four.meme), bots watch the launchpad instead and buy in the first seconds of the curve; the rising curve price means each successive bot pays more, which thins them. In a race, the entry is spread over five minutes and four chains with pools that will be consolidated at the oracle price, so being first by a block on one chain is worth much less; the creator's required first buy also means the lowest-price coins belong to a visible address rather than a script. The sniper bot guide explains why each design changes the bot's math.

• Direct DEX pools (Clanker, Zora, the post-consolidation race pool) are native ETH or BNB pairs on Uniswap or PancakeSwap, which DexScreener, GMGN and trading bots index automatically. No listing step.
• Curve coins are shown by DexScreener and similar trackers through launchpad integrations, in a separate category, and graduate to the main pair lists later.
• Each platform also has its own feed: pump.fun's site, four.meme's site, Zora's social feed, Clanker's Farcaster presence, sasa's Explore page, which lists its own coins beside the busiest coins from other DEXs on the same chains and shows only coins that pass an automated safety check.
• A coin at the same address on every chain, as in a race, is easier to search for and harder to copycat, which the guide to same-address deployment covers.

Side by side

1. Chain: Solana / BNB Chain / Base / Base / decided by buyers among Base, BNB Chain, Robinhood Chain and Arc.
2. Launch mechanism: bonding curve / bonding curve / direct Uniswap pool / content coin with Uniswap pool / four native pools consolidated into one after five minutes.
3. DEX pool from block one: no / no / yes / yes / yes, on four chains.
4. Creator pays with: SOL / BNB / ETH / ETH / USDC, first buy of $5 or more per chain plus a few cents of network fees.
5. Creator income: trading-based share per pump.fun's terms / per four.meme's terms / share of pool fees / share of trading on the content coin / 30% of every trading fee forever, or buyback and burn.
6. Liquidity after launch: per pump.fun's handling / per four.meme's handling / held by the factory / protocol pools / locked forever by the protocol.
7. Snipeable first block: on the curve / on the curve / yes, DEX pool / yes, DEX pool / spread over five minutes and four chains.

Which model fits which creator

• You have a Solana audience: pump.fun, because that is where the buyers and the tooling are.
• You have a BNB Chain audience and want a slow build on a curve: four.meme; for a direct pool on BNB Chain, see the direct PancakeSwap option in BNB Chain meme coin launchpads.
• You are on Farcaster and want a coin in one message: Clanker.
• The coin is a piece of content and you are a creator first: Zora.
• You do not know which chain your buyers are on, do not want to hold a gas token and want a definite launch moment with locked liquidity: a launch race. Meme coin launchpads on Base places the race among the Base options specifically, and how the 5-minute launch race works has the full sequence.

None of the five is the wrong answer for everyone. The right one is the one whose first minute, chain and fee terms match what you are actually trying to do, and the only way to be sure of the terms on the day you launch is to read each platform's documentation then, since all five change them.
