Locked liquidity
On graduation, 100% of liquidity is locked forever. Mooner's graduation contract holds the Project X position and has no function to withdraw it. Liquidity cannot be withdrawn by the creator, the protocol, or any other party.
The pool keeps earning trading fees. The lock keeps the right to collect them, and those fees pay the creator and the protocol after graduation. See Creator rewards.
Mooner migrates and locks every coin automatically the moment its curve fills. The transactions are also permissionless, so they never depend on Mooner's servers: if Mooner were ever down, anyone could send them.
