function factory() external view returns (address)

The contract that deployed the pool, which must adhere to the IUniswapV3Factory interface

The pool's fee in hundredths of a bip, i.e. 1e-6

Return values:

tickSpacing (0xd0c93a7c)

function tickSpacing() external view returns (int24)

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.

Return values:

maxLiquidityPerTick (0x70cf754a)

function maxLiquidityPerTick() external view returns (uint128)

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
