Read-Only Functions#

owner#

function owner() external view returns (address);

Returns the address of the current factory owner. Can be changed by the current owner via setOwner

poolDeployer

function poolDeployer() external view returns (address);

Returns the address of the poolDeployer

farmingAddress

function farmingAddress() external view returns (address);

Is retrieved from the pools to restrict calling certain functions not by a tokenomics contract Returns the tokenomics contract address

vaultAddress

function vaultAddress() external view returns (address);

poolByPair

function poolByPair(address tokenA, address tokenB) external view returns (address pool);

Returns the pool address for a given pair of tokens and a fee, or address 0 if it does not exist. tokenA and tokenB may be passed in either token0/token1 or token1/token0 order

Params

• tokenA The contract address of either token0 or token1

• tokenB The contract address of the other token

Returns

• pool The pool address

State-Changing Functions

createPool

function createPool(address tokenA, address tokenB) external returns (address pool);

Creates a pool for the given two tokens and fee. tokenA and tokenB may be passed in either order: token0/token1 or token1/token0. tickSpacing is retrieved from the fee. The call will revert if the pool already exists, the fee is invalid, or the token arguments are invalid.

Params

• tokenA One of the two tokens in the desired pool

• tokenB The other of the two tokens in the desired pool

Returns

• pool The address of the newly created pool

setOwner

function setOwner(address _owner) external;

Updates the owner of the factory. Must be called by the current owner

Params

• _owner The new owner of the factory

setFarmingAddress

function setFarmingAddress(address _farmingAddress) external;

Updates tokenomics address on the factory

Params

• _farmingAddress The new tokenomics contract address

setVaultAddress

function setVaultAddress(address _vaultAddress) external;

Updates vault address on the factory

Params

• _vaultAddress The new vault contract address

setBaseFeeConfiguration

function setBaseFeeConfiguration(uint16 alpha1, uint16 alpha2, uint32 beta1, uint32 beta2, uint16 gamma1, uint16 gamma2, uint32 volumeBeta, uint16 volumeGamma, uint16 baseFee) external;

Changes initial fee configuration for new pools. Changes coefficients for sigmoids: α / (1 + e^( (β-x) / γ)) alpha1 + alpha2 + baseFee (max possible fee) must be <= type(uint16).max, gammas must be > 0

Params

• alpha1 max value of the first sigmoid

• alpha2 max value of the second sigmoid

• beta1 shift along the x-axis for the first sigmoid

• beta2 shift along the x-axis for the second sigmoid

• gamma1 horizontal stretch factor for the first sigmoid

• gamma2 horizontal stretch factor for the second sigmoid

• volumeBeta shift along the x-axis for the outer volume-sigmoid

• volumeGamma horizontal stretch factor the outer volume-sigmoid

• baseFee minimum possible fee
