What does it mean when a meme coin graduates?
On baselaunch, a meme coin graduates when its bonding curve has sold its last sellable token, 714,285,714 of the 1,000,000,000 supply. On an ETH pair, the curve holds 4.2 ETH at that point. That money and a fixed share of the reserved tokens then open a Uniswap v4 pool whose liquidity is locked for good.
Numbers checked on chain on 20 October 2026.
The technical detail is in the docs.
How does a meme coin graduate from the bonding curve to Uniswap?
Every coin starts with its full supply of 1,000,000,000 tokens on its own bonding curve. From the start, the curve holds back 285,714,286 tokens and only ever sells the other 714,285,714. The buy that takes the last sellable token closes the curve, and graduation runs inside that same transaction.
The reserved amount follows from the virtual reserve and the graduation target. Every coin launched on the same settings therefore graduates into a pool of the same size, at the same price. It makes no difference whether the curve was bought out in one buy or in ten thousand.
The curve prices tokens as if it already held 1.68 ETH on an ETH pair. That virtual reserve is never paid out. Between the opening price of 0.00000000168 ETH and the final curve price of 0.00000002058 ETH, the price rises 12.25x.
Other pairs have their own targets. A USDC coin graduates at 8,090 USDC, for example, and every pair's target is 2.5 times its virtual reserve.
What happens to the final buy?
The last buy is filled only up to what is left on the curve. You pay for the tokens you receive, and the rest of your payment comes back in the same transaction. Nobody can make the finishing buy fail by leaving an awkward remainder. Your price limit still holds. A clamped buy may receive fewer tokens than you asked for, but never a worse price per token.
What opens the Uniswap pool at graduation?
The curve priced tokens as if it held 1.68 ETH more than it really did. A pool can only be funded with real money, so it receives just enough of the reserved tokens to open at exactly the curve's final price. Someone who bought the last curve token pays the same price the pool quotes a moment later.
| At graduation, ETH pair | Amount |
|---|---|
| Pair asset into the pool | 4.2 ETH |
| Tokens into the pool | 204,081,633 |
| Tokens locked permanently | 81,632,653 |
| Pool opening price | 0.00000002058 ETH |
From then on the coin trades in that pool, through baselaunch or any app that routes Uniswap v4. Pool trades pay a 1% base fee plus the coin's creator fee. The pool charges no fee of its own. The fee is taken by the protocol's pool hook, so you never pay a second pool fee on top.
Where does the supply end up after graduation?
| Holder | Tokens | Share of supply |
|---|---|---|
| Buyers' wallets (sold by the curve) | 714,285,714 | 71.4% |
| Uniswap v4 pool, locked liquidity | 204,081,633 | 20.4% |
| Locked for good, never circulating | 81,632,653 | 8.2% |
The pool's liquidity is a full-range Uniswap v4 position held by a liquidity locker, together with the 81,632,653 tokens locked at graduation. The locker has no withdraw function. This is not a promise to leave the liquidity alone. The function to take it out does not exist, so no key, including the owner's, can call it.
No more coins can be minted later. The coin contract has no mint function and no owner.
What happens if a graduation gets stuck?
Graduation has two steps. First the curve's reserves move out of the curve, then the pool is created and seeded with them. Both normally happen inside the finishing buy.
The finishing transaction may run short of gas. In that case the coin waits in a finished state, and anyone can complete graduation later with a public function. baselaunch also runs a service that does this automatically. If seeding fails, anyone can retry it at any time, without the creator or baselaunch.
Between the finished curve and the open pool, selling to the curve stops. The curve is holding exactly what the pool will open with, so a sell is refused rather than filled at a price that would change the pool.
In the rare case where the pool can never be seeded, the owner can send the reserves to an address the owner names, to be returned off chain. This is possible 7 days after the sweep when the pool seed is refused, or 30 days after when it still looks seedable. While a seed is possible, anyone can still seed the pool. A coin rescued this way is marked as rescued on chain for good.
Is graduation a sign that a coin is good?
No. Graduation is a step, not a verdict. It means the curve sold out. It says nothing about a coin's quality and promises no price or volume afterwards. Many coins never reach it.
Treat a graduated coin like any other. Check its contract address, its creator fee and who holds large balances.
Risks
- Meme coins are highly speculative and most lose their value. Nothing here is financial advice.
- The contracts have not been independently audited yet. An audit is part of our plan.
- Graduation is not a quality signal, and many coins never reach it.
- Every trade pays the 1% trading fee and the coin's creator fee of up to 10%. Buying and selling straight away loses money even if the price does not move.
- A creator can hold a large share from the opening buy and sell it at any time.
- Names and tickers are not unique or verified. The contract address is the only identity a coin has.
- On a pair other than ETH, the pair asset's own risk adds to the coin's.
- The owner can redirect a coin's creator fees after a 3-day notice.
- Prices and charts on the site are estimates read from the chain and can lag behind it.
- Transactions on Base are final. Nobody can reverse a trade or return a loss.

Questions
When does a baselaunch coin graduate?
A coin graduates when its bonding curve has sold all 714,285,714 sellable tokens. On an ETH pair the curve then holds 4.2 ETH, and that money opens a Uniswap v4 pool.
Do my tokens change when a coin graduates?
No. Your balance is the same ERC-20 token before and after graduation. Only the place you trade it changes, from the bonding curve to the Uniswap v4 pool.
Can the liquidity be removed after graduation?
No. The pool position is held by a liquidity locker that has no withdraw function, so no key, including the owner's, can take the liquidity out.
Does graduation mean a coin is a good investment?
No. Graduation only means the curve sold out. It says nothing about a coin's quality and promises no price or volume afterwards, and many coins never reach it.
What fee do I pay after a coin graduates?
Trades in the pool pay a 1% base fee with the same split as on the curve, plus the coin's creator fee of up to 10%. The pool charges no separate fee of its own.
Every cost is on fees, and what the owner can and cannot do is on security.
