Events

PoolCreated

event PoolCreated(
    address indexed token0,
    address indexed token1,
    uint24 indexed fee,
    int24 tickSpacing,
    address pool,
    uint256 exid
)

Emitted when a pool is created

Parameters:​

Name	Type	Description
token0	address	The first token of the pool by address sort order
token1	address	The second token of the pool by address sort order
fee	uint24	The fee collected upon every swap in the pool, denominated in hundredths of a bip
tickSpacing	int24	The minimum number of ticks between initialized ticks
pool	address	The address of the created pool

FeeAmountEnabled​

event FeeAmountEnabled(
    uint24 fee,
    int24 tickSpacing
)

Emitted when a new fee amount is enabled for pool creation via the factory

Parameters:​

Name	Type	Description
fee	uint24	The enabled fee, denominated in hundredths of a bip
tickSpacing	int24	The minimum number of ticks between initialized ticks for pools created with the given fee

Read-Only Functions

Read-Only Functions

getPoolCount

function getPoolCount() external view override returns (uint256);

Get the number of pools created in V3

Return Values:​

Name	Type	Description
	uint256	The number of pools created in V3

getPoolAddress

function getPoolAddress(uint256 idx) external view override returns (address);

Parameters:

Name	Type	Description
idx	uint256	The index number

Return Values:​

Name	Type	Description
	address	The address of the pool

getPool​

function getPool(
    address tokenA,
    address tokenB,
    uint24 fee
) 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

Parameters:​

Name	Type	Description
tokenA	address	The contract address of either token0 or token1
tokenB	address	The contract address of the other token
fee	uint24	The fee collected upon every swap in the pool, denominated in hundredths of a bip

Return Values:​

Name	Type	Description
pool	address	The pool address

feeAmountTickSpacing​

function feeAmountTickSpacing(
    uint24 fee
) external view returns (int24)

Returns the tick spacing for a given fee amount, if enabled, or 0 if not enabled

A fee amount can never be removed, so this value should be hard coded or cached in the calling context

Parameters:​

Name	Type	Description
fee	uint24	The enabled fee, denominated in hundredths of a bip. Returns 0 in case of unenabled fee

Return Values:​

Type	Description
int24	tick spacing

State-Changing Functions

State-Changing Functions

createPool

function createPool(
    address tokenA,
    address tokenB,
    uint24 fee
) 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.

Parameters:​

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
fee	uint24	The desired fee for the pool

Return Values:​

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

enableFeeAmount​

function enableFeeAmount(
    uint24 fee,
    int24 tickSpacing
) external

Enables a fee amount with the given tickSpacing

Fee amounts may never be removed once enabled

Parameters:​

Name	Type	Description
fee	uint24	The fee amount to enable, denominated in hundredths of a bip (i.e. 1e-6)
tickSpacing	int24	The spacing between ticks to be enforced for all pools created with the given fee amount
