These parameters are fixed for a pool forever, i.e., the methods will always return the same values

Functions

factory

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

function factory() external view returns (address);

Returns

token0

The first of the two tokens of the pool, sorted by address

function token0() external view returns (address);

Returns

token1

The second of the two tokens of the pool, sorted by address

function token1() external view returns (address);

Returns

fee

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

function fee() external view returns (uint24);

Returns

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

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
