State Variables

SWAP

We need all these selectors for executing a single swap

bytes32 private constant SWAP = 0xf3cd914c00000000000000000000000000000000000000000000000000000000

EXTTLOAD

bytes32 private constant EXTTLOAD = 0x9bf6645f00000000000000000000000000000000000000000000000000000000

Functions

constructor

constructor() ;

unlockCallback

Callback from uniswap V4 type singletons As Balancer V3 shares the same trigger selector and (unlike this one) has a custom selector provided, we need to skip this part of the data This is mainly done to not have duplicate code and maintain the same level of security by callback validation for both DEX types

function unlockCallback(bytes calldata data) external;

_getV4TypeAmountOut

Calculates amountOut for Uniswap V4 style pools

Note: calldata-offset-table:

function _getV4TypeAmountOut(
    uint256 fromAmount,
    address tokenIn,
    address tokenOut,
    uint256 currentOffset
)
    internal
    returns (
        uint256 receivedAmount,
        // similar to other implementations, we use this temp variable
        // to avoid stackToo deep
        uint256 tempVar
    );

Parameters

Returns

_simSwapUniswapV4ExactInGeneric

Simulates a swap on Uniswap V4 pools

Note: calldata-offset-table:

function _simSwapUniswapV4ExactInGeneric(
    uint256 fromAmount,
    address tokenIn,
    address tokenOut, //
    uint256 currentOffset
)
    internal;
