Debt Issuance Module v2

The DebtIssuanceModuleV2 module (Etherscan) is a smart contract that enables users to issue and redeem SetTokens that contain default and all external positions, including debt positions. Module hooks are added to allow for syncing of positions, and component-level hooks are added to ensure positions are replicated correctly. The manager can define arbitrary issuance logic in the manager hook, as well as specify issue and redeem fees.

issue()

function issue(ISetToken _setToken, uint256 _quantity, address _to)‌

Deposits components to the SetToken, replicates any external module component positions, and mints the SetToken. If the token has a debt position all collateral will be transferred in first then debt will be returned to the minting address. If specified, a fee will be charged on issuance.

NOTE: Overrides DebtIssuanceModule#issue external function and adds under-collateralization checks in place of the previous default strict balances checks. The under-collateralization checks are implemented in IssuanceValidationUtils library and they revert upon under-collateralization of the SetToken post-component transfer.

Parameter Name	Type	Description
_setToken	ISetToken	Instance of the SetToken
_quantity	uint256	Quantity of the SetToken to mint
_to	address	Address to mint SetToken to

redeem()

function redeem( ISetToken _setToken, uint256 _quantity,address _to)‌

Returns components from the SetToken, unwinds any external module component positions and burns the SetToken. If the token has debt positions, the module transfers in the required debt amounts from the caller and uses those funds to repay the debts on behalf of the SetToken. All debt will be paid down first then equity positions will be returned to the minting address. If specified, a fee will be charged on redeem.

NOTE: Overrides DebtIssuanceModule#redeem internal function and adds under-collateralization checks in place of the previous default strict balances checks. The under-collateralization checks are implemented in IssuanceValidationUtils library and they revert upon under-collateralization of the SetToken post-component transfer.

Parameter Name	Type	Description
_setToken	ISetToken	Address of the SetToken
_quantity	uint256	Quantity of the SetToken toredeem
_to	address	Address to redeem components to‌

initialize()

function initialize(ISetToken _setToken, uint256 _maxManagerFee, uint256 _managerIssueFee, uint256 _managerRedeemFee, address _feeRecipient, IManagerIssuanceHook _managerIssuanceHook)‌

Manager only. Initializes this module to the SetToken with issuance-related hooks. Only callable by the SetToken's manager. Hook addresses are optional. Address(0) means that no hook will be called

Parameter Name	Type	Description
_setToken	ISetToken	Address of the SetToken
_maxManagerFee	uint256	Max manager fee
_managerIssueFee	uint256	Issuance fee
_managerRedeemFee	uint256	Redemption fee
_feeRecipient	address	Fee recipient address
_preIssueHook	IManagerIssuanceHook	Instance of the Manager Contract with the Pre-Issuance Hook function
