Launchpad hook that charges fees in the payment token on each swap: a fixed 1% base fee plus a creator-configured tax up to 10%, split between a protocol recipient and a creator recipient via BeforeSwapDelta and AfterSwapReturnDelta. Liquidity additions are restricted to an approved position manager. Pool graduation is tracked by checking whether the current tick has crossed a configured graduation tick after each swap.

What it can do to your swap

  • Can take a fee from your outputAfter the pool fills your swap, the hook can keep part of what you were about to receive.
  • Can change the price you getBefore your swap runs, the hook can take or add tokens, so the amount you get is set by its code as well as the pool.
  • Runs code before your swap and can block itThe hook is called before every swap. It can revert, which makes your swap fail.
  • Runs code after your swap and can block itThe hook is called after every swap. It can revert, which undoes your swap.
  • Can block people from adding liquidityCalled before each deposit into the pool.
  • Runs code when a pool is createdCalled once, when someone creates a pool with this hook.
  • Runs code after a pool is createdCalled once, right after a pool with this hook is created.
