<none> | address | The token contract address |
fee ​
The pool's fee in hundredths of a bip, i.e. 1e-6
function fee() external view returns (uint24);Returns
| Name | Type | Description |
|---|---|---|
<none> | uint24 | The fee |
tickSpacing ​
The pool tick spacing
Ticks can only be used at multiples of this value, minimum of 1 and always positive e.g.: a tickSpacing of 3 means ticks can be initialized every 3rd tick, i.e., ..., -6, -3, 0, 3, 6, ... This value is an int24 to avoid casting even though it is always positive.
function tickSpacing() external view returns (int24);Returns
| Name | Type | Description |
|---|---|---|
<none> | int24 | The tick spacing |
maxLiquidityPerTick ​
The maximum amount of position liquidity that can use any tick in the range
This parameter is enforced per tick to prevent liquidity from overflowing a uint128 at any point, and also prevents out-of-range liquidity from being used to prevent adding in-range liquidity to a pool
function maxLiquidityPerTick() external view returns (uint128);Returns
| Name | Type | Description |
|---|---|---|
<none> | uint128 | The max amount of liquidity per tick |
