WarpX V3 Factory

The WarpX V3 Factory enables permissionless creation of WarpX V3 liquidity pools for any ERC20 token pair.

Creating a New Pool

function createPool(address tokenA, address tokenB, uint24 fee) external returns (address pool)

Creates a liquidity pool for the given token pair and fee tier.

• Tokens can be passed in any order; they will be sorted internally

• Reverts if the pool already exists or if the fee tier is not supported

• Returns the address of the newly created pool

Parameters:

Name	Type	Description
tokenA	address	One of the two tokens in the pool
tokenB	address	The other token in the pool
fee	uint24	Fee tier (e.g., 500, 3000, 10000) in hundredths of a bip

Example:

address pool = factory.createPool(USDC, WETH, 3000); // 0.30% fee tier

Querying Existing Pools

function getPool(address tokenA, address tokenB, uint24 fee) external view returns (address pool)

Returns the pool address for a token pair and fee tier, or address(0) if it doesn't exist.

Parameters:

Name	Type	Description
tokenA	address	First token address
tokenB	address	Second token address
fee	uint24	Fee tier

Example:

address pool = factory.getPool(USDC, WETH, 3000);require(pool != address(0), "Pool does not exist");

Checking Fee Tier Validity

function feeAmountTickSpacing(uint24 fee) external view returns (int24)

Returns the tick spacing for a fee tier, or 0 if the fee tier is not enabled.

Parameters:

Name	Type	Description
fee	uint24	Fee amount to check

Example:

int24 tickSpacing = factory.feeAmountTickSpacing(3000);require(tickSpacing != 0, "Fee tier not supported");

Supported Fee Tiers

Fee	Tick Spacing	Use Case
100 (0.01%)	1	Stablecoin pairs (e.g., USDC/USDT)
500 (0.05%)	10	Correlated assets (e.g., WETH/stETH)
3000 (0.30%)	60	Most token pairs
10000 (1.00%)	200	Exotic or high-volatility pairs
