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
