# Check if a pool exists (V2)

> Check whether a SaucerSwap V2 pool exists for a token pair and fee tier with the factory getPool function before minting a new liquidity position.

<Tip>
  Checking if the liquidity pool with the matching fee tier exists using SaucerSwap's REST API is also a suitable alternative. For more information, see [Get all Liquidity Pools (V2)](/developers/v2/liquidity/fetch-all-pools).

| Parameter Name   | Description                                                                       |
| ---------------- | --------------------------------------------------------------------------------- |
| *address token0* | The contract address of either token0 or token1                                   |
| *address token1* | The contract address of the other token                                           |
| *uint24 fee*     | The fee collected upon every swap in the pool, denominated in hundredths of a bip |

<CodeGroup>
  ```solidity IUniswapV3Factory.sol theme={null}
  /// @notice Returns the pool address for a given pair of tokens and a fee, or address 0 if it does not exist
  /// @dev tokenA and tokenB may be passed in either token0/token1 or token1/token0 order
  /// @param tokenA The contract address of either token0 or token1
  /// @param tokenB The contract address of the other token
  /// @param fee The fee collected upon every swap in the pool, denominated in hundredths of a bip
  /// @return pool The pool address
  function getPool(
    address tokenA,
    address tokenB,
    uint24 fee
  ) external view returns (address pool);
  ```
</CodeGroup>

<Tip>
  When working with HBAR, use the WHBAR (Wrapped HBAR) token address for either tokenA or tokenB.
</Tip>

<Note>
  The ordering of tokens for token0 and token1 does not matter.
</Note>

<Note>
  If the pool does not exist, a zero address will be returned.
