Wrap Module

The WrapModuleV2 (Etherscan) is a smart contract that enables the wrapping of ERC20 and Ether positions via third-party protocols. The WrapModule works in conjunction with WrapAdapters, in which the wrapAdapterID / integrationNames are stored on the integration registry. Examples of wrap actions include wrapping DAI to cDAI (Compound) or DAI to aDAI (Aave).

wrap()

function wrap(ISetToken _setToken, address _underlyingToken, address _wrappedToken, uint256 _underlyingUnits, string calldata _integrationName)

Manager only. Instructs the SetToken to wrap an underlying asset into a wrappedToken via a specified adapter.

Parameter Name	Type	Description
_setToken	ISetToken	Instance of the SetToken
_underlyingToken	address	Address of the component to be wrapped
_wrappedToken	address	Address of the desired wrapped token
_underlyingUnits	uint256	Quantity of underlying units in Position units
_integrationName	string	Name of wrap module integration (mapping on integration registry)

wrapWithEther()

function wrapWithEther(ISetToken _setToken, address _wrappedToken, uint256 _underlyingUnits, string calldata _integrationName)

Manager only. Instructs the SetToken to wrap Ether into a wrappedToken via a specified adapter. Since SetTokens only hold WETH, in order to support protocols that collateralize with Ether the SetToken's WETH must be unwrapped first before sending to the external protocol.

Parameter Name	Type	Description
_setToken	ISetToken	Instance of the SetToken
_wrappedToken	address	Address of the desired wrapped token
_underlyingUnits	uint256	Quantity of underlying units in Position units
_integrationName	string	Name of wrap module integration (mapping on integration registry)

unwrap()

function unwrap(ISetToken _setToken, address _underlyingToken, address _wrappedToken, uint256 _wrappedUnits, string calldata _integrationName)

Manager only. Instructs the SetToken to wrap an underlying asset into a wrappedToken via a specified adapter.

Parameter Name	Type	Description
_setToken	ISetToken	Instance of the SetToken
_underlyingToken	address	Address of the component to be wrapped
_wrappedToken	address	Address of the desired wrapped token
_wrappedUnits	uint256	Quantity of wrapped units in Position units
_integrationName	string	Name of wrap module integration (mapping on integration registry)

unwrapWithEther()

function unwrapWithEther(ISetToken _setToken, address _wrappedToken, uint256 _wrappedUnits, string calldata _integrationName)

Manager only. Instructs the SetToken to wrap an underlying asset into a wrappedToken via a specified adapter.

Parameter Name	Type	Description
_setToken	ISetToken	Instance of the SetToken
_wrappedToken	address	Address of the desired wrapped token
_wrappedUnits	uint256	Quantity of wrapped units in Position units
_integrationName	string	Name of wrap module integration (mapping on integration registry)

initialize()

function initialize(ISetToken _setToken)

Manager only. Initializes this module to the SetToken.

Parameter Name	Type	Description
_setToken	ISetToken	Address of the SetToken
