AlgebraPool
Algebra concentrated liquidity pool
This contract is responsible for liquidity positions, swaps and flashloans
Developer note: Version: Algebra V2-directional-fee
Functions
initialize
function initialize(uint160 initialPrice) external
external
Sets the initial price for the pool Developer note: Price is represented as a sqrt(amountToken1/amountToken0) Q64.96 value Initialization should be done in one transaction with pool creation to avoid front-running
mint
function mint(address sender, address recipient, int24 bottomTick, int24 topTick, uint128 liquidityDesired, bytes data) external returns (uint256 amount0, uint256 amount1, uint128 liquidityActual)
external
Adds liquidity for the given recipient/bottomTick/topTick position Developer note: The caller of this method receives a callback in the form of IAlgebraMintCallback# AlgebraMintCallback in which they must pay any token0 or token1 owed for the liquidity. The amount of token0/token1 due depends on bottomTick, topTick, the amount of liquidity, and the current price. If bottomTick == topTick position is treated as a limit order
Returns:
burn
function burn(int24 bottomTick, int24 topTick, uint128 amount) external returns (uint256 amount0, uint256 amount1)
external
Burn liquidity from the sender and account tokens owed for the liquidity to the position Developer note: Can be used to trigger a recalculation of fees owed to a position by calling with an amount of 0 Fees must be collected separately via a call to #collect
Returns:
collect
function collect(address recipient, int24 bottomTick, int24 topTick, uint128 amount0Requested, uint128 amount1Requested) external returns (uint128 amount0, uint128 amount1)
external
Collects tokens owed to a position Developer note: Does not recompute fees earned, which must be done either via mint or burn of any amount of liquidity. Collect must be called by the position owner. To withdraw only token0 or only token1, amount0Requested or amount1Requested may be set to zero. To withdraw all tokens owed, caller may pass any value greater than the actual tokens owed, e.g. type(uint128).max. Tokens owed may be from accumulated swap fees or burned liquidity.
Returns:
swap
function swap(address recipient, bool zeroToOne, int256 amountRequired, uint160 limitSqrtPrice, bytes data) external returns (int256 amount0, int256 amount1)
external
Swap token0 for token1, or token1 for token0 Developer note: The caller of this method receives a callback in the form of IAlgebraSwapCallback#AlgebraSwapCallback
Returns:
swapSupportingFeeOnInputTokens
function swapSupportingFeeOnInputTokens(address sender, address recipient, bool zeroToOne, int256 amountRequired, uint160 limitSqrtPrice, bytes data) external returns (int256 amount0, int256 amount1)
external
Swap token0 for token1, or token1 for token0 (tokens that have fee on transfer) Developer note: The caller of this method receives a callback in the form of IAlgebraSwapCallback#AlgebraSwapCallback
Returns:
flash
function flash(address recipient, uint256 amount0, uint256 amount1, bytes data) external
external
Receive token0 and/or token1 and pay it back, plus a fee, in the callback Developer note: The caller of this method receives a callback in the form of IAlgebraFlashCallback#AlgebraFlashCallback All excess tokens paid in the callback are distributed to currently in-range liquidity providers as an additional fee. If there are no in-range liquidity providers, the fee will be transferred to the first active provider in the future
setCommunityFee
function setCommunityFee(uint8 newCommunityFee) external
external
Set the community's % share of the fees. Cannot exceed 25% (250). Only factory owner or POOLS_ADMINISTRATOR_ROLE role
setTickSpacing
function setTickSpacing(int24 newTickSpacing, int24 newTickspacingLimitOrders) external
external
Set the new tick spacing values. Only factory owner or POOLS_ADMINISTRATOR_ROLE role
setIncentive
function setIncentive(address newIncentiveAddress) external
external
Sets an active incentive. Only farming
