What is a bonding curve?
A bonding curve is a price formula built into the coin's pool. When people buy, SOL goes into the curve and the price goes up; when they sell, SOL comes out and the price goes down. There's no order book and no one setting the price — the formula does it, on-chain.
On MemeLaunch every coin starts on a Meteora dynamic bonding curve. Because the price starts very low, early buyers pay less — which is also why the first ~2 minutes have a higher anti-sniper fee (starting around 5% and sliding to 1%), so bots can't scoop up everything instantly.
What does "graduation" mean?
Each curve has a target. When enough SOL has been bought into the curve (on MemeLaunch's current setup, about 110 SOL), the coin graduates: its liquidity moves into a regular DEX pool and the bonding curve closes.
You can see every coin's progress bar on its page — "35% to graduation" means the curve is 35% of the way there.
What happens to the liquidity after graduation?
By default the new pool's liquidity is locked permanently on-chain, so nobody (not the creator, not MemeLaunch) can withdraw it. A creator can instead choose to control 90% of it (10% always stays locked); those coins carry a ⚠️ warning and the creator can add or remove liquidity after graduation. That removes the classic "pull the liquidity" rug after graduation.
It doesn't make the coin safe: the price can still fall hard if holders sell. Locked liquidity just means the pool can't be emptied by one person.
Where does a coin trade after it graduates?
In its DEX pool, so it shows on DexScreener, GeckoTerminal and in wallet swap screens like Jupiter. The coin page links to it. Creator fees keep coming from trades in the graduated pool too.
Reading the numbers on a coin page
- In the curve — how much SOL is sitting in the bonding curve right now.
- Market cap — price × the coin's total supply (1 billion unless the creator picked another number).
- Traders 24h — different wallets that traded, not counting the creator.
- Trending score — a 0–100 score from real trading by outside wallets. How it's worked out →
Common questions
Can the creator take the SOL out of the bonding curve?
No. The SOL in the curve can only come out when someone sells tokens back into it. After graduation the liquidity is locked permanently by default (unless the creator chose to control it, which the coin page flags).
Why does my buy cost more than the price I saw?
Buying moves the price up the curve as you buy, plus there is a 1% trading fee (higher in a coin's first ~2 minutes). The trade screen shows the estimated price impact and the minimum you'll receive before you approve.
Does graduation mean the coin is safe?
No. By default it means the pool liquidity is locked so it can't be pulled (unless the creator chose to control it, which the coin page flags). The price can still drop to near zero if holders sell.
