Structs

GlobalState

The struct with important state values of pool

Developer note: fits into one storage slot

struct GlobalState {
  uint160 price;
  int24 tick;
  uint16 lastFee;
  uint8 pluginConfig;
  uint16 communityFee;
  bool unlocked;
}

Name	Description
price	The square root of the current price in Q64.96 format
tick	The current tick (price(tick) <= current price). May not always be equal to SqrtTickMath.getTickAtSqrtRatio(price) if the price is on a tick boundary
lastFee	The current (last known) fee in hundredths of a bip, i.e. 1e-6 (so 100 is 0.01%). May be obsolete if using dynamic fee plugin
pluginConfig	The current plugin config as bitmap. Each bit is responsible for enabling/disabling the hooks, the last bit turns on/off dynamic fees logic
communityFee	The community fee represented as a percent of all collected fee in thousandths, i.e. 1e-3 (so 100 is 10%)
unlocked	Reentrancy lock flag, true if the pool currently is unlocked, otherwise - false

Selector: 0x70cf754a

The maximum amount of position liquidity that can use any tick in the range

Developer note: 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

The Algebra factory contract, which must adhere to the IAlgebraFactory interface

token0

address immutable token0

Selector: 0x0dfe1681

The timestamp of the last sending of tokens to community vault

plugin

address plugin

tickSpacing

int24 tickSpacing

Selector: 0xd0c93a7c

The current tick spacing

Developer note: Ticks can only be initialized by new mints at multiples of this value e.g.: a tickSpacing of 60 means ticks can be initialized every 60th tick, i.e., ..., -120, -60, 0, 60, 120, ... However, tickspacing can be changed after the ticks have been initialized. This value is an int24 to avoid casting even though it is always positive.
