setupRiskScores

function setupRiskScores(struct DataTypes.Storage _poolStorage, uint32[] _daysPastDues, uint32[] _ratesAndDefaults, uint32[] _periodsAndWriteOffs) external

This function sets up risk scores for securitization pool. It requires that the input arrays are sorted and have equal lengths, where each element of one array corresponds to an index in the other two arrays. The function also emits a 'SetRiskScore' event with the new risk scores as parameter.

Parameters

Name	Type	Description
_poolStorage	struct DataTypes.Storage	storage object for pool details
_daysPastDues	uint32[]	array of days past due periods
_ratesAndDefaults	uint32[]	array of rates and defaults corresponding to each day past due period
_periodsAndWriteOffs	uint32[]	array of periods and write offs corresponding to each day past due period

exportAssets

function exportAssets(struct DataTypes.NFTAsset[] _nftAssets, address tokenAddress, address toPoolAddress, uint256[] tokenIds) external

This function exports NFT assets from the pool to another address.

Parameters

Name	Type	Description
_nftAssets	struct DataTypes.NFTAsset[]	The array of NFT assets in the pool.
tokenAddress	address	The address of the ERC721 token contract.
toPoolAddress	address	The address where the assets will be transferred to.
tokenIds	uint256[]	The IDs of the tokens that are being exported from the pool.

withdrawAssets

function withdrawAssets(struct DataTypes.NFTAsset[] _nftAssets, address[] tokenAddresses, uint256[] tokenIds, address[] recipients) external

This function allows users to withdraw their NFT assets from the pool.

Parameters

Name	Type	Description
_nftAssets	struct DataTypes.NFTAsset[]	The array of NFT assets in the pool.
tokenAddresses	address[]	The addresses of the tokens that represent the NFTs.
tokenIds	uint256[]	The IDs of the NFTs to be withdrawn.
recipients	address[]	The addresses of the users who will receive the NFTs.

getLoansValue

function getLoansValue(struct DataTypes.Storage _poolStorage, uint256[] tokenIds, struct DataTypes.LoanEntry[] loanEntries) external view returns (uint256 expectedAssetsValue, uint256[] expectedAssetValues)

Calculates the total value of loans and individual loan values.

The function calculates the expected asset value based on the provided loan entries for each tokenId. It also returns an array with the calculated values for each tokenId.

Parameters

Name	Type	Description
_poolStorage	struct DataTypes.Storage	Pool storage object.
tokenIds	uint256[]	Array of token IDs.
loanEntries	struct DataTypes.LoanEntry[]	Array of loan entries corresponding to the token IDs.

Return Values

Name	Type	Description
expectedAssetsValue	uint256	Total value of all loans.
expectedAssetValues	uint256[]	Array with individual loan values for each tokenId.

collectAssets

function collectAssets(struct DataTypes.Storage _poolStorage, uint256[] tokenIds, struct DataTypes.LoanEntry[] loanEntries) external returns (uint256)

This function collects NFT assets from users and adds them to the pool. It also updates the pool's NAV (Net Asset Value).

Parameters

Name	Type	Description
_poolStorage	struct DataTypes.Storage	The storage of the pool.
tokenIds	uint256[]	An array of token IDs representing the NFT assets being collected.
loanEntries	struct DataTypes.LoanEntry[]	An array of LoanEntry structs containing information about each loan.

Return Values

Name	Type	Description
[0]	uint256	expectedAssetsValue The total value of the collected assets.

setUpOpeningBlockTimestamp

function setUpOpeningBlockTimestamp(struct DataTypes.Storage _poolStorage) public

This function sets up the opening block timestamp for a pool.

Parameters

Name	Type	Description
_poolStorage	struct DataTypes.Storage	The storage object of the pool.

_setOpeningBlockTimestamp

function _setOpeningBlockTimestamp(struct DataTypes.Storage _poolStorage, uint64 _openingBlockTimestamp) internal

This function sets the opening block timestamp.

Parameters

Name	Type	Description
_poolStorage	struct DataTypes.Storage	The storage of the pool.
_openingBlockTimestamp	uint64	The new opening block timestamp.
