uint256 private __amountIn = type(uint256).max;

Functions

exactOutputSingle

Perform an exact output single swap.

function exactOutputSingle(
    address recipient,
    IMaverickV2Pool pool,
    bool tokenAIn,
    uint256 amountOut,
    uint256 amountInMaximum
) public payable returns (uint256 amountIn, uint256 amountOut_);

Parameters

Name	Type	Description
recipient	address	The address of the recipient.
pool	IMaverickV2Pool	The Maverick V2 pool to swap with.
tokenAIn	bool	A boolean indicating if token A is the input.
amountOut	uint256	The amount of output tokens desired.
amountInMaximum	uint256	The maximum amount of input tokens allowed.

Returns

Name	Type	Description
amountIn	uint256	The amount of input tokens used for the swap.
amountOut_	uint256	The actual amount of output tokens received.

outputSingleWithTickLimit

Perform an output-specified single swap with tick limit check.

function outputSingleWithTickLimit(
    address recipient,
    IMaverickV2Pool pool,
    bool tokenAIn,
    uint256 amountOut,
    int32 tickLimit,
    uint256 amountInMaximum,
    uint256 amountOutMinimum
) public payable returns (uint256 amountIn_, uint256 amountOut_);

Parameters

Name	Type	Description
recipient	address	The address of the recipient.
pool	IMaverickV2Pool	The Maverick V2 pool to swap with.
tokenAIn	bool	A boolean indicating if token A is the input.
amountOut	uint256	The amount of output tokens desired.
tickLimit	int32	The tick limit for the swap.
amountInMaximum	uint256	The maximum amount of input tokens allowed.
amountOutMinimum	uint256	The minimum amount of output tokens expected.

Returns

Name	Type	Description
amountIn_	uint256	The actual amount of input tokens used for the swap.
amountOut_	uint256	The actual amount of output tokens received. This amount can vary from the requested amountOut due to the tick limit. If the pool swaps to the tick limit, it will stop filling the order and return the amount out swapped up to the ticklimit to the user.

exactOutputMultiHop

Perform an exact output multihop swap.

function exactOutputMultiHop(address recipient, bytes memory path, uint256 amountOut, uint256 amountInMaximum)
    external
    payable
    returns (uint256 amountIn);

Parameters

Name	Type	Description
recipient	address	The recipient address.
path	bytes	The swap path as encoded bytes.
amountOut	uint256	The exact output amount.
amountInMaximum	uint256	The maximum input amount allowed.

Returns

Name	Type	Description
amountIn	uint256	The input amount for the swap.

inputSingleWithTickLimit

Perform an input-specified single swap with tick limit check.

function inputSingleWithTickLimit(
    address recipient,
    IMaverickV2Pool pool,
    bool tokenAIn,
    uint256 amountIn,
    int32 tickLimit,
    uint256 amountOutMinimum
) public payable returns (uint256 amountIn_, uint256 amountOut);

Parameters

Name	Type	Description
recipient	address	The address of the recipient.
pool	IMaverickV2Pool	The Maverick V2 pool to swap with.
tokenAIn	bool	A boolean indicating if token A is the input.
amountIn	uint256	The amount of input tokens.
tickLimit	int32	The tick limit for the swap.
amountOutMinimum	uint256	The minimum amount of output tokens expected.

Returns

Name	Type	Description
amountIn_	uint256	The actual input amount used for the swap. This may differ from the amount the caller specified if the pool reaches the tick limit. In that case, the pool will consume the input swap amount up to the tick limit and return the resulting output amount to the user.
amountOut	uint256	The amount of output tokens received.

_exactOutputInternal

function _exactOutputInternal(uint256 amountOut, address recipient, CallbackData memory data)
    private
    returns (uint256 amountIn);

maverickV2SwapCallback

function maverickV2SwapCallback(IERC20 tokenIn, uint256 amountToPay, uint256, bytes calldata _data) external override;

Structs

CallbackData

struct CallbackData {
    bytes path;
    address payer;
}
