GoodReserveCDai

The GoodReserveCDai mints G$ based on the interest transferred from the FundManager. Only the FundManager can trigger minting.

The contract also acts as the GoodDollar liquidity pool and AMM (Automatic Market Maker) and enables methods to buy and sell G$s.
Events
UBIMinted
Emitted when new G$ tokens are minted.
Parameter name
Annotation
day
Epoch of UBI.
interestToken
The token paid as interest.
interestReceived
Wei amount of interest paid in interestToken.
gdInterestMinted
Amount of G$ tokens that was added to the supply as result of mintInterest function.
gdExpansionMinted
Amount of G$ tokens that was added to the supply as a result of mintExpansion function.
gdUbiTransferred
Amount of G$ tokens that was minted to the ubiCollector contract.
event UBIMinted(
    uint256 indexed day,
    address indexed interestToken,
    uint256 interestReceived,
    uint256 gdInterestMinted,
    uint256 gdExpansionMinted,
    uint256 gdUbiTransferred
);
TokenPurchased
Emitted when G$ tokens are purchased from the reserve.
Parameter name
Annotation
caller
The initiate person of the event.
inputToken
The convertible token address which the G$ tokens were purchased with.
inputAmount
Reserve tokens amount.
actualReturn
Actual return of the tokens after the conversion.
receiverAddress
The address of the receiver of tokens.
event TokenPurchased(
    address indexed caller,
    address indexed inputToken,
    uint256 inputAmount,
    uint256 actualReturn,
    address indexed receiverAddress
);
TokenSold
Emitted when G$ tokens are sold to the reserve.
Parameter name
Annotation
caller
The initiate person of the event.
outputToken
The convertible token address which the G$ tokens were sold to.
gdAmount
Reserve tokens amount.
contributionAmount
Actual return of the tokens after the conversion.
actualReturn
The address of the receiver of tokens.
receiverAddress
The address of the receiver of the tokens.
event TokenSold(
	address indexed caller,
	address indexed outputToken,
	uint256 gdAmount,
	uint256 contributionAmount,
	uint256 actualReturn,
	address indexed receiverAddress
);
buy
Converts cDai tokens to GD tokens and updates the bonding curve params. The buy occurs only if the G$ return is above the given minimum. It is possible to buy only with cDAI and when the contract is set to active. MUST call to cDAI approve prior this action to allow this contract to accomplish the conversion.
Parameter name
Annotation
_tokenAmount
The amount of cDAI tokens that should be converted to G$ tokens.
_minReturn
The minimum allowed return in G$ tokens.
_targetAddress
Address of G$ and GOOD recipient if different than msg.sender.
Returns: How much G$ tokens were transferred.
function buy(
    uint256 _tokenAmount,
    uint256 _minReturn,
    address _targetAddress
) external returns (uint256);
sell
The sell helper function burns G$ tokens and update the bonding curve params. The sell occurs only if the token return is above the given minimum. Notice that there is a contribution amount from the given GD that remains in the reserve.
Parameter name
Annotation
_gdAmount
The amount of GD tokens that should be converted to cDAI tokens.
_minReturn
The minimum allowed amount of cDAI tokens to return.
_target
Address of the receiver of cDAI when sell G$.
_seller
Address of the seller when using helper contract.
Returns: The tuple of two: cDAI received amount and G$ exit contribution.
function sell(
		uint256 _gdAmount,
		uint256 _minReturn,
		address _target,
		address _seller
	) external returns (uint256, uint256);
mintRewardFromRR
Mint rewards for staking contracts in G$ and update RR requires minting permissions which is enforced by _mintGoodDollars function.
Parameter name
Annotation
_token
The amount of GD tokens that should be converted to cDAI tokens.
_to
The minimum allowed amount of cDAI tokens to return.
_amount
Address of the receiver of cDAI when sell G$.
Returns: The tuple of two: cDAI received amount and G$ exit contribution.
function mintRewardFromRR(
		address _token,
		address _to,
		uint256 _amount
	) public;
mintUBI
Only FundManager or other with mint G$ permission can call this to trigger minting. Reserve sends UBI + interest to FundManager.
Parameter name
Annotation
_daiToConvert
DAI amount to convert cDAI.
_startingCDAIBalance
Initial cDAI balance before staking collect process start.
_interestToken
The token that was transfered to the reserve.
Returns: The tuple of two: how much GD UBI was minted and how much cDAI collected from staking contracts.
function mintUBI(
		uint256 _daiToConvert,
		uint256 _startingCDAIBalance,
		ERC20 _interestToken
	) public returns (uint256, uint256)
