Read-Only Functions

Read-Only Functions

owner

• Governance Contract Address

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

• When the addresses of tokenA and tokenB 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[tokenA][tokenB] == tokenToPool[tokenB][tokenA]

createFee

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

• deprecated

getPoolCount

function getPoolCount() public view returns (uint)

• Returns the current number of registered liquidity pools.

getPoolAddress

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

• Returns the liquidity pair contract address of the pair's index.

State-Changing Functions

State-Changing Functions

createKlayPool

function createETHPool(address token, uint256 amount, uint256 fee) public payable

• A method called to add a liquidity pair with one side as KLAY

• Token for when the KLAY-KIP7 pair to be registered has never been registered before

• Parameters

  • token : KIP7 token address to add liquidity

  • amount : the amount of tokens (KIP7) to be provided for the initial liquidity

  • fee : Sets the initial fee value for liquidity pairs

    • A value between 30 and 100

    • Meaning: 30 -> 0.3%, 100 -> 1%

  • msg.value : KLAY quantity to initially supply liquidity

    • Delivers the transaction value without specifying otherwise

createTokenPool

function createTokenPool(address token0, uint256 amount0, address token1, uint256 amount1, uint256 fee) public

• A method called to add a liquidity pair with both ERC20

• Token for when the ERC20-ERC20 pair to be registered has never been registered before

• 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
