how meme works

meme is the OG launchpad, rebuilt on Raydium. Coins start on a bonding curve at about $4,000 market cap, the way pump.fun used to do it, and graduate into a real Raydium pool with all of the LP burned. The twist: every fee a coin makes goes back into that same coin. Nobody gets paid out. Not us, not the creator.

what meme is

Every coin here is a pool on Raydium LaunchLab, the program behind Raydium's own launchpad, created on meme's LaunchLab platform. That means the curve, the trading and the migration all happen inside Raydium's audited programs. meme never holds your coins or your SOL while you trade: you sign every trade in your own wallet, straight against Raydium.

What meme adds on top is the bag. Each coin gets its own wallet, and meme's share of the trading fees is spent on that coin, automatically, forever.

launching a coin

Go to launch, add a picture, a name, a ticker, and optionally a description and an X link. That's it. There's no website or Telegram field: a coin's website is always its own page on meme, and it's written into the token's metadata automatically.

free launches

With no first buy, launching is free. Your wallet signs a short message (it costs nothing and can't move funds), and meme pays the on-chain rent to create the coin. You're recorded as the launcher. To keep this from being spammed, free launches are limited to 3 per wallet per day and 60 per hour across the site.

launching with a first buy

If you want to be first in, set a first buy (up to 50 SOL). Then your wallet pays the launch itself (around 0.03 SOL of rent) and buys your coin in the very same transaction, so nobody can get in before you.

the address

meme grinds contract addresses ending in meme in the background. If one is ready when you launch, your coin gets it. If they've all been used, it gets a normal address. It doesn't change anything else.

the bonding curve

Every coin has 1,000,000,000 tokens with 6 decimals, the same as the OG pump.fun coins. 793,100,000 of them are sold on the curve. The other 206,900,000 are kept in the curve and go into the Raydium pool at graduation, together with all the SOL the curve raised.

The curve is constant product, like OG pump.fun: the price starts low and climbs as people buy. On the original curve (an 85 SOL raise) a coin started at about 27.96 SOL of market cap. Since SOL's price moves, meme sizes each coin's raise at launch so it spawns at about $4,000:

raise = 85 × 4,000 ÷ (27.96 × SOL price), kept between 30 and 400 SOL.

At $100 SOL that's about a 122 SOL raise: a coin starts at about 40 SOL (≈ $4k) of market cap and graduates at about 590 SOL (≈ $59k), roughly 15× its starting price, the same shape pump.fun had. The raise is fixed for a coin once it's launched, and shown on its page.

fees

Every trade on a curve pays 1.25% of its SOL side:

0.25% to Raydium, LaunchLab's own protocol fee.
1% to meme's platform, which is all spent on the coins: 90% into the coin's own bag and 10% into the $MEME bag.
0% to the creator. Creators don't earn on meme, on purpose: a coin's fees make the coin stronger instead of paying someone to dump it.

After graduation, the Raydium pool charges its own 0.25% swap fee, which stays in the pool as liquidity, plus a 0.05% creator fee. On meme, a coin's on-chain creator is its bag, so that creator fee goes to the bag too and gets compounded like everything else.

the bag

Every coin is born with its own bag, a wallet run by meme's engine that only ever does two things with that coin:

while the coin is on its curve, the bag buys the coin. That's buy pressure from every trade, forever, and it pushes the curve toward graduation.
once the coin is on Raydium, the bag pairs up what it holds and adds it as liquidity to the coin's Raydium pool, then burns the LP tokens it gets back. That liquidity can never be removed by anyone.

Bag buys show up in the trade list with a bag icon. The bag never sells its tokens to cash out: tokens it bought on the curve end up as burned liquidity after graduation. Each coin's page shows its bag's address, what it holds, what it has bought and what it has burned.

the engine, step by step

Every 10 minutes the engine runs one cycle. Every step is an on-chain transaction you can check, and every one is written to the log.

measure. LaunchLab keeps a running counter of Raydium's 0.25% fee on every pool. meme's 1% is charged on the exact same amounts, so each coin's share of the platform fee is that counter's growth × 4.
claim. Platform fees from every coin collect in one shared vault on LaunchLab. Once it holds at least 0.01 SOL, the engine claims it.
split. The claim is divided between coins by what each one earned since the last claim: 90% to the coin's bag and 10% to the $MEME bag.
deliver. Each share is sent to its bag once it's at least 0.003 SOL. Smaller shares wait for the next cycle.
compound. Bags on a curve buy their coin. Bags of graduated coins collect the pool's creator fee, balance their SOL and tokens at the pool price, add liquidity and burn the LP.

If a step fails (a busy network, say), nothing is lost: the amounts stay recorded and the next cycle picks up where this one stopped. The keeper wallet that runs the engine pays the network fees. Bag keys are kept encrypted on meme's server, and the engine only ever uses them to buy the coin, add liquidity and burn LP. Every one of those transactions is in the log.

graduation and LP burn

When a curve has raised its target, trading on it stops and Raydium's migrator moves it into a Raydium CPMM pool (Raydium's standard constant product pool) with the curve's SOL and the 206,900,000 reserved tokens. meme's platform is set so that 100% of that pool's LP is burned at migration. Nobody, including meme and the creator, can ever pull that liquidity.

A note on "OG Raydium pools": LaunchLab used to migrate coins into Raydium's older AMM v4 pools, but Raydium no longer allows new curves to migrate there. Every new LaunchLab coin, on any launchpad, now graduates into a CPMM pool. It's the same constant product AMM and trades everywhere Raydium does: Jupiter, Raydium's app, Dexscreener and every wallet.

$MEME

$MEME is meme's own coin, launched here on the same curve as everything else. It gets 10% of every other coin's bag share, plus 100% of its own, and its bag does the same thing as every bag: buys $MEME on the curve, then adds burned liquidity once it graduates. The more coins trade on meme, the more goes into $MEME.

trading

You can trade from any coin's page. While a coin is on its curve, trades go to its LaunchLab pool; after graduation, to its Raydium pool. Either way the transaction is built for you, you sign it in your own wallet, and it goes straight to Raydium's programs. Slippage is set on the trade panel (10% by default). Coins also trade on Raydium's own app, and graduated coins on every aggregator.

faq

does the creator get anything?

No. Creator fees are 0% on the curve, and the pool's creator fee after graduation goes to the coin's bag.

where does meme make money?

It doesn't take a cut of coins. The 10% house share goes into $MEME's bag, which is spent on $MEME itself.

why does my coin's market cap say ~$4k before anyone bought?

That's the curve's starting price × 1B supply, the same way pump.fun coins started at a few thousand dollars.

can I change my coin's picture or name?

No. Token metadata is set at launch.

what if the curve fills while I'm buying?

Buys are quoted against what's left on the curve, so the last buy fills it. Then Raydium migrates it, usually within a minute or so, and trading moves to the Raydium pool.

risks

Please read this.

Memecoins are extremely risky. Most go to zero. Only put in what you can afford to lose completely.
Anyone can launch anything here. A coin being on meme says nothing about who made it or why.
Bag buys and burned liquidity make a coin's floor thicker, they don't make it go up. Holders can still sell.
meme relies on Raydium's programs and on Solana. Bugs, outages or changes there can affect every coin.
The engine is run by meme and bag keys sit on meme's server. If the engine stopped, fees would wait in the platform vault until it ran again.
Nothing here is financial advice.
