Functions

quote

function quote(uint256 amountIn, bytes calldata data) external returns (uint256 amountOut);

_quoteSingleSwapSplitOrRoute

function _quoteSingleSwapSplitOrRoute(
    uint256 amountIn,
    address tokenIn,
    uint256 currentOffset
)
    internal
    returns (uint256 amountOut, uint256, address nextToken);

_quoteSingleSwap

We use the receiver as an additional addres needed for quoting for DEXs like GMX and KTX

function _quoteSingleSwap(
    uint256 amountIn,
    address tokenIn,
    address tokenOut,
    address receiverParam,
    uint256 currentOffset
)
    internal
    returns (uint256 amountOut, uint256);

_quoteMultiHopSplitSwap

function _quoteMultiHopSplitSwap(
    uint256 amountIn,
    uint256 swapMaxIndex,
    address tokenIn,
    uint256 currentOffset
)
    internal
    returns (uint256 amount, uint256, address _tokenIn);

_quoteSingleSwapOrSplit

Ensures that all paths end with the same currency

Parallel swaps a->...->b; a->...->b for different DEXs

Notes:

• calldata-offset-table:

• split-format: | Offset | Length (bytes) | Description | |--------|----------------|----------------------| | 0 | 1 | count | | 1 | 2*count - 1 | splits | <- count = 0 means there is no data, otherwise uint16 splits

• datas-format: | Offset | Length (bytes) | Description | |--------|----------------|----------------------| | 0 | 2 | (r,c) | <- indicates whether the swap is non-simple (further splits or hops) | 2 | 1 | dexId | | 3 | variable | params | <- depends on dexId (fixed for each one) | 3+v | 2 | (r,c) | | 4+v | 1 | dexId | | ... | variable | params | <- depends on dexId (fixed for each one) | ... | ... | ... | <- count + 1 times of repeating this pattern

function _quoteSingleSwapOrSplit(
    uint256 amountIn,
    uint256 splitsMaxIndex,
    address tokenIn,
    uint256 currentOffset
)
    internal
    returns (uint256, uint256, address);
