GenericSwapFacetV3

How it works

The GenericSwapFacetV3 is a gas-optimized new version of the GenericSwapFacet and offers the same functionality as its predecessor: executing single swaps or multiple same-chain swaps in a single transaction. It will send the result of the (final) swap to the specified receiver address. New in this version is that in cases where a DEX does not pull/use all of the inputTokens for a swap (positive slippage), these tokens will be sent to the receiver address.

Public Methods

  • function swapTokensSingleERC20ToERC20(bytes32 _transactionId,string calldata _integrator,string calldata _referrer,address payable _receive,uint256 _minAmountOut,LibSwap.SwapData calldata _swapData)

    • Performs a single swap from an ERC20 to another ERC20 token

  • function swapTokensSingleERC20ToNative(bytes32 _transactionId,string calldata _integrator,string calldata _referrer,address payable _receive,uint256 _minAmountOut,LibSwap.SwapData calldata _swapData)

    • Performs a single swap from an ERC20 to the network's native token

  • function swapTokensSingleNativeToERC20(bytes32 _transactionId,string calldata _integrator,string calldata _referrer,address payable _receive,uint256 _minAmountOut,LibSwap.SwapData calldata _swapData)

    • Performs a single swap from the network's native token to an ERC20 token

  • function swapTokensGenericV3FromNative(bytes32 _transactionId, string calldata _integrator, string calldata _referrer, address payable _receiver, uint256 _minAmount, SwapData[] calldata _swapData)

    • Performs multiple swap(s) with the native token as initial input token before withdrawing the final token to the user

  • function swapTokensGenericV3FromERC20(bytes32 _transactionId, string calldata _integrator, string calldata _referrer, address payable _receiver, uint256 _minAmount, SwapData[] calldata _swapData)

    • Performs multiple swap(s) with any ERC20 token as initial input token before withdrawing the final token to the user

Swap Data

Some methods accept a SwapData _swapData parameter.

This parameter is defined in the following library:
