IUniswapV3PoolImmutables

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

factory

function factory() external view returns (address)

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

Name Type Description
[0] address The contract address

token0

function token0() external view returns (address)

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

Name Type Description
[0] address The token contract address

token1

function token1() external view returns (address)

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

Name Type Description
[0] address The token contract address

fee

function fee() external view returns (uint24)

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

Name Type Description
[0] uint24 The fee

tickSpacing

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.

Name Type Description
[0] int24 The tick spacing

maxLiquidityPerTick

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

Name Type Description
[0] uint128 The max amount of liquidity per tick
