# PoolInitializer

## Functions

### createAndInitializePoolIfNecessary

```solidity theme={null}
  function createAndInitializePoolIfNecessary(
    address token0,
    address token1,
    int24 tickSpacing,
    uint160 sqrtPriceX96
  ) external returns (address pool)
```

Creates a new pool if it does not exist, then initializes if not initialized

This method can be bundled with others via IMulticall for the first action (e.g. mint) performed against a pool

#### Parameters:

| `token1`       | address | The contract address of token1 of the pool                   |
| `tickSpacing`  | int24   | The tick spacing of the v3 pool for the specified token pair |
| `sqrtPriceX96` | uint160 | The initial square root price of the pool as a Q64.96 value  |

#### Return Values:

| Name   | Type    | Description                                                                                                                    |
