CrowdHook

A launch helper hook. It only lets approved callers create pools.

• Only approved callers create pools

  New pools with this hook can only be created by approved callers, for example its own factory or launcher.

  The code that does this (beforeInitialize):

  function beforeInitialize(address, PoolKey calldata key, uint160) external onlyPoolManager returns (bytes4) {
      if (poolSet) revert PoolAlreadySet();
      if (!key.currency0.isAddressZero() || Currency.unwrap(key.currency1) != token) revert WrongPool();
      if (tx.origin != launcher) revert NotLauncher();
      poolId = key.toId();
      poolSet = true;
      poolKey = key;
      emit PoolSet(poolId);
      return IHooks.beforeInitialize.selector;
  }

• Anyone can trigger payouts

  Anyone can collect the fees it has built up, so nobody has to wait on the hook developer.

  The code that does this (collectLpFees):

  function collectLpFees() external {
      if (lpUnlockAt == 0) revert NoPosition();
      uint256 tokenId = lpTokenId;
      bytes memory actions = abi.encodePacked(uint8(0x01), uint8(0x11));
      bytes[] memory params = new bytes[](2);
      params[0] = abi.encode(tokenId, uint256(0), uint128(0), uint128(0), bytes(""));
      params[1] = abi.encode(poolKey.currency0, poolKey.currency1, feeRecipient);
      emit LpFeesCollected(tokenId, feeRecipient);
      positionManager.modifyLiquidities(abi.encode(actions, params), block.timestamp);
  }

Who controls it: The pool creator can call: register lp, extend lock, wls, bls. The code cannot be changed.

Based on the hook’s published code.
