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.

Functions

constructor

PeripheryImmutableState

constructor(address,address,address) public

Name	Type	Description
_factory	address
_WNativeToken	address
_poolDeployer	address

algebraSwapCallback

algebraSwapCallback(int256,int256,bytes) view external

Called to `msg.sender` after executing a swap via IAlgebraPool#swap.

Name	Type	Description
amount0Delta	int256	The amount of token0 that was sent (negative) or must be received (positive) by the pool by the end of the swap. If positive, the callback must send that amount of token0 to the pool.
amount1Delta	int256	The amount of token1 that was sent (negative) or must be received (positive) by the pool by the end of the swap. If positive, the callback must send that amount of token1 to the pool.
