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

Events

Events

ChangeNextOwner

event ChangeNextOwner(address nextOwner);

• Event to pre-register new owner

• owner will be governance smart contract (In Intial period before KSP distributed, DEV team have owner permission)

ChangeOwner

event ChangeOwner(address owner);

• Event that completes changing the owner

Read-Only Functions

Read-Only Functions

owner

• Governance 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 liquidity pool pair exists

tokenToPool

• The contract address corresponding to the tokenA, tokenB pair

• 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]

getPoolCount

function getPoolCount() public view returns (uint256)

• Returns the current number of registered liquidity pools.

getPoolAddress

function getPoolAddress(uint256 idx) public view returns (address)

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

State-Changing Functions

State-Changing Functions

changeNextOwner

function changeNextOwner(address _nextOwner) public

• Method to set the next Owner in advance before changing Owner

• only owner

changeOwner

function changeOwner() public

• Method for the next Owner to change the actual Owner

• only nextOwner

createETHPool

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

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

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

• Parameters

  • token : ERC20 token address to add liquidity

  • amount : the amount of tokens (ERC20) 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 : ETH 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

• Method called to add liquidity pair in case of ERC20 token pair

• 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
