AlgebraFactory

Algebra factory

Is used to deploy pools and its dataStorages

Developer note: Version: Algebra V2-directional-fee

Variables

bytes32 POOLS_ADMINISTRATOR_ROLE constant

role that can change communityFee and tickspacing in pools

address poolDeployer immutable

Returns the current poolDeployerAddress

address communityVault immutable

Returns the current communityVaultAddress

address farmingAddress

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

uint8 defaultCommunityFee

Returns the default community fee

uint256 renounceOwnershipStartTimestamp

struct AlgebraFeeConfiguration defaultFeeConfiguration

Developer note: values of constants for sigmoids in fee calculation formula

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

Returns the pool address for a given pair of tokens, 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) public public

Name	Type	Description
_poolDeployer	address

owner

function owner() public view returns (address) view public

Returns the current owner of the factory Developer note: Can be changed by the current owner via transferOwnership(address newOwner)

Returns:

Name	Type	Description
[0]	address	The address of the factory owner

hasRoleOrOwner

function hasRoleOrOwner(bytes32 role, address account) public view returns (bool) view public

Developer note: Returns `true` if `account` has been granted `role` or `account` is owner.

Name	Type	Description
role	bytes32
account	address

Returns:

Name	Type	Description
[0]	bool

createPool

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

Creates a pool for the given two tokens Developer note: tokenA and tokenB may be passed in either order: token0/token1 or token1/token0. The call will revert if the pool already exists 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

setFarmingAddress

function setFarmingAddress(address newFarmingAddress) external external

Developer note: updates tokenomics address on the factory

Name	Type	Description
newFarmingAddress	address	The new tokenomics contract address

setDefaultCommunityFee

function setDefaultCommunityFee(uint8 newDefaultCommunityFee) external external

Developer note: updates default community fee for new pools

Name	Type	Description
newDefaultCommunityFee	uint8	The new community fee, must be <= MAX_COMMUNITY_FEE

setDefaultFeeConfiguration

function setDefaultFeeConfiguration(struct AlgebraFeeConfiguration newConfig) 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 and gammas must be > 0

Name	Type	Description
newConfig	struct AlgebraFeeConfiguration	new default fee configuration. See the #AdaptiveFee.sol library for details

startRenounceOwnership

function startRenounceOwnership() external external

Starts process of renounceOwnership. After that, a certain period of time must pass before the ownership renounce can be completed.

stopRenounceOwnership

function stopRenounceOwnership() external external

Stops process of renounceOwnership and removes timer.

renounceOwnership

function renounceOwnership() public public

Developer note: Leaves the contract without owner. It will not be possible to call `onlyOwner` functions anymore. Can only be called by the current owner if RENOUNCE_OWNERSHIP_DELAY seconds have passed since the call to the startRenounceOwnership() function.
