How it works
Graduation
The curve sells its last token, shuts for good, and the coin moves onto a Uniswap v4 pool. The liquidity goes into a contract with no withdraw function.
A coin graduates when its curve has sold everything it was allowed to sell: the 71.43% of supply on offer, reached at 75 OKB in. No vote, no approval, no waiting period. The transaction that buys the last token starts it.
What happens#
Both amounts were fixed before the coin ever traded. The curve had been collecting OKB — the pool's own quote asset — since the first buy, so seeding needs no swap, no price oracle and no judgement call about what the pool opens at.
The liquidity is locked#
Not held by the creator. Not held by a multisig. Not held by us with a promise not to touch it. It's minted into a contract whose code has no function that can move it: no withdraw, no transfer, no emergency exit, nothing behind a timelock. Ownership of that contract exists only to have wired it to the factory once.
A graduated size.fun coin can't be rugged by pulling its liquidity, because there's no code path that pulls it.
Check it yourself
Read LaunchLocker on OKLink. It's verified, so the absence of a withdrawal function is something you can confirm rather than take our word for.
Fees carry across#
Every graduated pool shares one Uniswap v4 hook. It charges the same 1% and splits it the same 30% protocol / 70% creator. A creator tax carries over at whatever rate the coin launched with.
Fees land in the same escrow balance the curve's did, so one claim collects both. Nothing about a creator's earnings changes at the boundary, which is why the split was built the same on both sides of it.
Trading a graduated coin#
It's an ordinary Uniswap v4 pool from here. Trade it on size.fun or through any interface or router that speaks v4 on X Layer. The curve contract still exists but will never fill another trade.
What changes for you:
- The pool sets the price, not the launch formula. It can go below the graduation price — the curve's floor doesn't follow the coin across.
- The depth is real. The pool holds the 75 OKB the curve took in, as liquidity nobody can withdraw.
- Anyone can add liquidity alongside it. Nobody can remove the launchpad's own position.
If graduation doesn't land in one go#
Graduation is two phases: sweep the curve's reserves, then seed the pool. Normally both happen inside the buy that crossed the line. If the second phase doesn't land — a transient failure, or the buyer running out of gas — the coin sits swept and unsettled, and anyone can finish it by calling the pool creation themselves. It's permissionless, retryable, and costs nothing but gas.
Otherwise a launch could stall on one wallet's gas limit.
