Risk Score Rules. All risk rules are measured in in terms of USD with 18 decimals of precision.

This contract implements rules to be checked by an Application Handler.

​

Functions

​

checkAccountMaxValueByRiskScore

_maxValue array size must be equal to _riskScore array size. The positioning of the arrays is ascendant in terms of risk scores, and descendant in the value array. (i.e. if highest risk score is 99, the last balanceLimit will apply to all risk scores of 100.) eg. risk scores balances resultant logic

0-24 = NO LIMIT 25 500 25-49 = 500 50 250 50-74 = 250 75 100 75-99 = 100

Account Max Value By Risk Score

function checkAccountMaxValueByRiskScore(
    uint32 _ruleId,
    address _toAddress,
    uint8 _riskScore,
    uint128 _totalValueTo,
    uint128 _amountToTransfer
) external view;

Parameters

​

getAccountMaxValueByRiskScore

If recipient address being checked is zero address the rule passes (This allows for burning)

Function to get the Account Max Value By Risk Score rule by index

function getAccountMaxValueByRiskScore(uint32 _index)
    public
    view
    returns (ApplicationRuleStorage.AccountMaxValueByRiskScore memory);

Parameters

Returns

​

getTotalAccountMaxValueByRiskScore

Function to get total Account Max Value By Risk Score rules registered

function getTotalAccountMaxValueByRiskScore() public view returns (uint32);

Returns

​

checkAccountMaxTxValueByRiskScore

that these max value ranges are set by risk score ranges.

_maxValue size must be equal to _riskScore The positioning of the arrays is ascendant in terms of risk scores, and descendant in the size of transactions. (i.e. if highest risk score is 99, the last balanceLimit will apply to all risk scores of 100.) eg. risk scores balances resultant logic

0-24 = NO LIMIT 25 500 25-49 = 500 50 250 50-74 = 250 75 100 75-99 = 100

Rule that checks if the tx exceeds the limit size in USD for a specific risk profile within a specified period of time.

this check will cause a revert if the new value of _valueTransactedInPeriod in USD exceeds the limit for the address risk profile.

function checkAccountMaxTxValueByRiskScore(
    uint32 ruleId,
    uint128 _valueTransactedInPeriod,
    uint128 txValue,
    uint64 lastTxDate,
    uint8 _riskScore
) external view returns (uint128);

Parameters

Returns

​

getAccountMaxTxValueByRiskScore

Function to get the Account Max Transaction Value By Risk Score rule.

function getAccountMaxTxValueByRiskScore(uint32 _index)
    public
    view
    returns (ApplicationRuleStorage.AccountMaxTxValueByRiskScore memory);

Parameters

Returns

​

getTotalAccountMaxTxValueByRiskScore

Function to get total Account Max Transaction Value By Risk Score rules

function getTotalAccountMaxTxValueByRiskScore() public view returns (uint32);

Returns
