• EthReceiver

Functions​

constructor​

function constructor(
  address weth,
  contract IClipperExchangeInterface clipperExchange
) public

Parameters:​

Name	Type	Description
weth	address
clipperExchange	contract IClipperExchangeInterface

clipperSwapToWithPermit​

function clipperSwapToWithPermit(
  address payable recipient,
  contract IERC20 srcToken,
  contract IERC20 dstToken,
  uint256 amount,
  uint256 minReturn,
  bytes permit
) external returns (uint256 returnAmount)

Same as clipperSwapTo but calls permit first, allowing to approve token spending and make a swap in one transaction.

Parameters:​

Name	Type	Description
recipient	address payable	Address that will receive swap funds
srcToken	contract IERC20	Source token
dstToken	contract IERC20	Destination token
amount	uint256	Amount of source tokens to swap
minReturn	uint256	Minimal allowed returnAmount to make transaction commit
permit	bytes	Should contain valid permit that can be used in IERC20Permit.permit calls. See tests for examples

clipperSwap​

function clipperSwap(
  contract IERC20 srcToken,
  contract IERC20 dstToken,
  uint256 amount,
  uint256 minReturn
) external returns (uint256 returnAmount)

Same as clipperSwapTo but uses msg.sender as recipient

Parameters:​

Name	Type	Description
srcToken	contract IERC20	Source token
dstToken	contract IERC20	Destination token
amount	uint256	Amount of source tokens to swap
minReturn	uint256	Minimal allowed returnAmount to make transaction commit

clipperSwapTo​

function clipperSwapTo(
  address payable recipient,
  contract IERC20 srcToken,
  contract IERC20 dstToken,
  uint256 amount,
  uint256 minReturn
) public returns (uint256 returnAmount)

Performs swap using Clipper exchange. Wraps and unwraps ETH if required. Sending non-zero msg.value for anything but ETH swaps is prohibited

Parameters:​

Name	Type	Description
recipient	address payable	Address that will receive swap funds
srcToken	contract IERC20	Source token
dstToken	contract IERC20	Destination token
amount	uint256	Amount of source tokens to swap
