Quoter

Provides quotes for swaps

Allows getting the expected amount out or amount in for a given swap without executing the swap

Developer note: These functions are not gas efficient and should not be called on chain. Instead, optimistically execute the swap and check the amounts in the callback. Credit to Uniswap Labs under GPL-2.0-or-later license: https://github.com/Uniswap/v3-periphery

Functions

constructor

constructor(address _factory, address _WNativeToken, address _poolDeployer) public public

algebraSwapCallback

function algebraSwapCallback(int256 amount0Delta, int256 amount1Delta, bytes path) external view view external

Called to `msg.sender` after executing a swap via IAlgebraPool#swap. Developer note: In the implementation you must pay the pool tokens owed for the swap. The caller of this method must be checked to be a AlgebraPool deployed by the canonical AlgebraFactory. amount0Delta and amount1Delta can both be 0 if no tokens were swapped.

quoteExactInputSingle

function quoteExactInputSingle(address tokenIn, address tokenOut, uint256 amountIn, uint160 limitSqrtPrice) public returns (uint256 amountOut, uint16 fee) public

Returns the amount out received for a given exact input but for a swap of a single pool

Returns:

quoteExactInput

function quoteExactInput(bytes path, uint256 amountIn) external returns (uint256 amountOut, uint16[] fees) external

Returns the amount out received for a given exact input swap without executing the swap

Returns:

quoteExactOutputSingle

function quoteExactOutputSingle(address tokenIn, address tokenOut, uint256 amountOut, uint160 limitSqrtPrice) public returns (uint256 amountIn, uint16 fee) public

Returns the amount in required to receive the given exact output amount but for a swap of a single pool

Returns:

quoteExactOutput

function quoteExactOutput(bytes path, uint256 amountOut) external returns (uint256 amountIn, uint16[] fees) external

Returns the amount in required for a given exact output swap without executing the swap

Returns:
