Introduction

SpaceMint is a token launchpad. In one transaction it deploys a fixed-supply ERC-20, opens a Uniswap v4 pool for it at the market cap you choose, and locks 100% of the supply as liquidity in an ownerless locker. Nobody can pull that liquidity: not the creator, and not SpaceMint.

What a launch does#

1. Deploys a token with a fixed supply (1,000,000,000 by default). No mint, no pause, no blacklist, no transfer tax, no owner.
2. Opens a Uniswap v4 pool between your token and the asset it trades against, with no hook.
3. Puts all of the supply into one single-sided position, from your starting price upward, so the first buyer sets the price.
4. Hands that position to the locker, which has no way to take liquidity out.
5. Fixes where the trading fee goes, forever.
