createPool(tokenA: address, tokenB: address, fee: uint24)
nonpayable
Creates a pool for the given two tokens and fee
dev: 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.
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 |
Returns
| Name | Type | Description |
|---|---|---|
| pool | address | pool The address of the newly created pool |
enableFeeAmount(fee: uint24, tickSpacing: int24)
nonpayable
Enables a fee amount with the given tickSpacing
dev: 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 |
setOwner(_owner: address)
nonpayable
Updates the owner of the factory
dev: Must be called by the current owner
Parameters
| Name | Type | Description |
|---|---|---|
| _owner | address | The new owner of the factory |
