AlgebraFactory

Algebra factory

Is used to deploy pools and its dataStorages

Modifiers

onlyOwner

modifier onlyOwner() internal

Variables

address owner

Returns the current owner of the factory

Developer note: Can be changed by the current owner via setOwner

address poolDeployer immutable

Returns the current poolDeployerAddress

address farmingAddress

Developer note: Is retrieved from the pools to restrict calling certain functions not by a tokenomics contract

address vaultAddress

struct AdaptiveFee.Configuration baseFeeConfiguration

mapping(address => mapping(address => address)) poolByPair

Returns the pool address for a given pair of tokens and a fee, or address 0 if it does not exist

Developer note: tokenA and tokenB may be passed in either token0/token1 or token1/token0 order

Functions

constructor

constructor(address _poolDeployer, address _vaultAddress) public public

Name	Type	Description
_poolDeployer	address
_vaultAddress	address

createPool

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

Creates a pool for the given two tokens and fee Developer note: 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.

Name	Type	Description
tokenA	address	One of the two tokens in the desired pool
tokenB	address	The other of the two tokens in the desired pool

Returns:

Name	Type	Description
pool	address	The address of the newly created pool

setOwner

function setOwner(address _owner) external external

Updates the owner of the factory Developer note: Must be called by the current owner

Name	Type	Description
_owner	address	The new owner of the factory

setFarmingAddress

function setFarmingAddress(address _farmingAddress) external external

Developer note: updates tokenomics address on the factory

Name	Type	Description
_farmingAddress	address	The new tokenomics contract address

setVaultAddress

function setVaultAddress(address _vaultAddress) external external

Developer note: updates vault address on the factory

Name	Type	Description
_vaultAddress	address	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 external

Changes initial fee configuration for new pools Developer note: 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

Name	Type	Description
alpha1	uint16	max value of the first sigmoid
alpha2	uint16	max value of the second sigmoid
beta1	uint32	shift along the x-axis for the first sigmoid
beta2	uint32	shift along the x-axis for the second sigmoid
gamma1	uint16	horizontal stretch factor for the first sigmoid
gamma2	uint16	horizontal stretch factor for the second sigmoid
volumeBeta	uint32	shift along the x-axis for the outer volume-sigmoid
volumeGamma	uint16	horizontal stretch factor the outer volume-sigmoid
baseFee	uint16	minimum possible fee
