updateAuths

function updateAuths(struct Structs.AddressBool[] authsStatus_) external

adds/removes auths. Auths generally could be contracts which can have restricted actions defined on contract. auths can be helpful in reducing governance overhead where it's not needed.

Parameters

Name	Type	Description
authsStatus_	struct Structs.AddressBool[]	array of structs setting allowed status for an address. status true => add auth, false => remove auth

updateGuardians

function updateGuardians(struct Structs.AddressBool[] guardiansStatus_) external

adds/removes guardians. Only callable by Governance.

Parameters

Name	Type	Description
guardiansStatus_	struct Structs.AddressBool[]	array of structs setting allowed status for an address. status true => add guardian, false => remove guardian

updateRevenueCollector

function updateRevenueCollector(address revenueCollector_) external

changes the revenue collector address (contract that is sent revenue). Only callable by Governance.

Parameters

Name	Type	Description
revenueCollector_	address	new revenue collector address

_updateExchangePrices

function _updateExchangePrices(address token_) internal returns (uint256 supplyExchangePrice_, uint256 borrowExchangePrice_)

updates the exchange prices in storage for token_and returnssupplyExchangePrice*andborrowExchangePrice*. Recommended to use only in a method that later calls _updateExchangePricesAndRates().

_updateExchangePricesAndRates

function _updateExchangePricesAndRates(address token_) internal returns (uint256 supplyExchangePrice_, uint256 borrowExchangePrice_)

_updates the exchange prices + rates in storage for token_and returnssupplyExchangePrice*andborrowExchangePrice*_
