Events, Read-Only Functions, and State-Changing Functions

Events

ChangeCreateFee

event ChangeCreateFee(uint _createFee);

An event to change the Pool Contract Creation Fee when adding a new liquidity pool pair

CreatePool

event CreatePool(address token0, uint amount0, address token1, uint amount1, uint fee, address exchange, uint exid);

Event to create new liquidity pool
parameters
- token0 : token0 address in pair
- amount0 : token0 amount in pool
- token1 : token1 address in pair
- amount1 : token1 amount in pool
- fee : pool fee rate
- exchange : exchange contract address of this pool
- exid : exchange id

Read-Only Functions

WETH

WETH contract address.

mesh

MESH contract address

allPairsLength

Returns the total number of pairs created through the factory so far.

getPoolCount

Returns the total number of pairs created through the factory so far.

createFee

The amount of MESH that must be paired to create a new liquidity pool pair

owner

Factory Contract Address

nextOwner

The next Governance Contract Address set in advance.

pools

List of liquidity pool pairings
Each item saves the smart contract address of the liquidity pool

poolExist

Returns if the contract for the given liquidiy pool pair exists

tokenToPool

The contract address corresponding to the token0, token1 pair
When the addresses of token0 and token1 are inputted, this returns the contract address of the corresponding pairing
Returns the same contract address regardless of the order of the liquidity pool pairing tokens:
tokenToPool[token0][token1] == tokenToPool[token1][token0]

allPairs

function allPairs(uint) external view returns (address pair);

Returns the address of the nth pair (0-indexed) created through the factory

getPair

function getPair(address token0, address token1) external view returns (address pair);

Returns the address of the pair for token0 and token1, if it has been created, else address(0) (0x0000000000000000000000000000000000000000).

getPoolAddress

function getPoolAddress(uint idx) public view returns (address)

Returns the address of the nth pair (0-indexed) created through the factory

State-Changing Functions

createETHPool

function createETHPool(address token, uint amount, uint fee) public payable

A method called to add a liquidity pair with one side as MATIC
The wallet that calls this must have MESH greater than or equal to createFee
Token for when the WMATIC / ERC-20 pair to be registered has never been registered before
Parameters
- token : ERC-20 token address to add liquidity
- amount : the amount of tokens (ERC-20) to be provided for the initial liquidity
- fee : Sets the initial fee value for liquidity pairs
  - A value between 0 and 100
  - Meaning: 0 -> 0%, 100 -> 1%
- msg.value : MATIC quantity to initially supply liquidity
  - Delivers the transaction value without specifying otherwise

createTokenPool

 function createTokenPool(address token0, uint amount0, address token1, uint amount1, uint fee) public

Method called to add liquidity pair in case of ERC-20 token pair
The wallet calling the MESH above createFee must have it.
parameter
- token0 : The address of the first token
- amount0 : The quantity of the first token that supplies the initial liquidity
- token1 : The address of the second token
- amount1 : The quantity of the second token that supplies the initial liquidity
- fee : Sets the initial fee value for liquidity pairs
