# IDragonswapV2PoolDeployer

A contract that constructs a pool must implement this to pass arguments to the pool

This is used to avoid having constructor arguments in the pool contract, which results in the init code hash of the pool being constant allowing the CREATE2 address of the pool to be cheaply computed on-chain

### Functions[​](https://docs.uniswap.org/contracts/v3/reference/core/interfaces/IUniswapV3PoolDeployer#functions) <a href="#functions" id="functions"></a>

#### parameters[​](https://docs.uniswap.org/contracts/v3/reference/core/interfaces/IUniswapV3PoolDeployer#parameters) <a href="#parameters" id="parameters"></a>

```solidity
  function parameters(
  ) external view returns (address factory, address token0, address token1, uint24 fee, int24 tickSpacing)
```

Get the parameters to be used in constructing the pool, set transiently during pool creation.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.dragonswap.app/dragonswap/resources/developer-resources/smart-contracts/dragonswapv2/core/interfaces/idragonswapv2pooldeployer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
