Function for clients

function swap(
    uint256 fromTokenAmount,
    SwapInfo[] calldata swapInfos,
    SwapInfo[] calldata targetChainSwapInfo,
    address receiver
)

ABI of contract could be found in this file.

Following are introductions of each parameter of the swap function.

fromTokenAmount

amount of token that a client swaps from

swapInfos

array of SwapInfo, containing information of each step on source chain. SwapInfo would be explained in the last.

targetChainSwapInfo

array of SwapInfo, containing information of each step on target chain.

receiver

address of the user that receives asset on target chain

struct SwapInfo {
    uint8 chainId;
    address dex;
    IERC20 fromToken;
    IERC20 toToken;
    bytes swapData;
}

chainId

ID of the chain that this swapInfo would be performed on. For example, if a client attempts to swap from ETH to BSC, chain_id of swapInfos would be 1; ones of targetChainSwapInfos would be 56.

dex

The "to" address of the swap action.

fromToken

The token planned to be swapped from of the swap action.

toToken

The token planned to be swapped for of the swap action.

swapData

The calldata that would be sent to dex.
