TokenSwapAdapter

Abstract contract for token swap adapters

Functions

executeTokenSwap

Executes series of token swaps and returns the hashes of the orders submitted/executed

function executeTokenSwap(ExternalTrade[] calldata externalTrades, bytes calldata data) external payable virtual;

Parameters

Name	Type	Description
`externalTrades`	`ExternalTrade[]`	The external trades to execute
`data`	`bytes`

completeTokenSwap

Completes the token swaps by confirming each order settlement and claiming the resulting tokens (if necessary).

*This function must return the exact amounts of sell tokens and buy tokens claimed per trade. If the adapter operates asynchronously (e.g., CoWSwap), this function should handle the following:

Cancel any unsettled trades to prevent further execution.
Claim the remaining tokens from the unsettled trades.*

function completeTokenSwap(ExternalTrade[] calldata externalTrades)
    external
    payable
    virtual
    returns (uint256[2][] memory claimedAmounts);

Parameters

Name	Type	Description
`externalTrades`	`ExternalTrade[]`	The external trades that were executed and need to be settled.

Returns

Name	Type	Description
`claimedAmounts`	`uint256[2][]`	A 2D array where each element contains the claimed amounts of sell tokens and buy tokens for each corresponding trade in `externalTrades`. The first element of each sub-array is the claimed sell amount, and the second element is the claimed buy amount.
