Factory

Inherits: IFactory

Author: typicalHuman.

Factory should be single instance for UX (finding pools for different tokens and for possible routing).

State Variables

address immutable s_owner;

mapping(address => mapping(address => address)) s_pools;

constructor();

Create new pool with 2 assets.

Pool should be unique (pool with these assets shouldn't be used on this factory yet).

function createPool(address token0, address token1) external returns (address poolAddress);

Parameters

Name	Type	Description
`token0`	`address`	First asset of the pool.
`token1`	`address`	Second asset of the pool.

Returns

Name	Type	Description
`poolAddress`	`address`	Address of newly created pool.

Get pool address based on assets.

The order matters.

function getPool(address token0, address token1) external view returns (address);

Parameters

Name	Type	Description
`token0`	`address`	First asset of the pool.
`token1`	`address`	Second asset of the pool.

Returns

Name	Type	Description
`<none>`	`address`	Address of the pool, if not found - returns zero address.

Get address which will receive protocol fees.

function getProtocolBeneficiary() external view returns (address);

event PoolCreated(address pool, address token0, address token1);

error TOKENS_NOT_SORTED();

error POOL_ALREADY_EXISTS();
