updateAuths
function updateAuths(struct Structs.AddressBool[] authsStatus_) externaladds/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.

|---|---|---|
| authsStatus_ | struct Structs.AddressBool | array of structs setting allowed status for an address. status true => add auth, false => remove auth |
updateGuardians

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

function updateRevenueCollector(address revenueCollector_) externalchanges the revenue collector address (contract that is sent revenue). Only callable by Governance.
Parameters
| Name | Type | Description |
|---|---|---|
| revenueCollector_ | address | new revenue collector address |
changeStatus
function changeStatus(uint256 newStatus_) externalchanges current status, e.g. for pausing or unpausing all user operations. Only callable by Auths.
Parameters
| Name | Type | Description |
|---|---|---|
| newStatus_ | uint256 | new status status = 2 -> pause, status = 1 -> resume. |
updateRateDataV1s
function updateRateDataV1s(struct Structs.RateDataV1Params[] tokensRateData_) externalupdate tokens rate data version 1. Only callable by Auths.
Parameters

| tokensRateData_ | struct Structs.RateDataV1Params | array of RateDataV1Params with rate data to set for each token |
updateRateDataV2s
function updateRateDataV2s(struct Structs.RateDataV2Params[] tokensRateData_) externalupdate tokens rate data version 2. Only callable by Auths.
Parameters
| Name | Type | Description |
|---|---|---|
| tokensRateData_ | struct Structs.RateDataV2Params | array of RateDataV2Params with rate data to set for each token |
updateTokenConfigs
function updateTokenConfigs(struct Structs.TokenConfig[] tokenConfigs_) externalupdates token configs: fee charge on borrowers interest & storage update utilization threshold. Only callable by Auths.
Parameters
| Name | Type | Description |

| tokenConfigs_ | struct Structs.TokenConfig | contains token address, fee & utilization threshold |
updateUserClasses
function updateUserClasses(struct Structs.AddressUint256[] userClasses_) externalupdates user classes: 0 is for new protocols, 1 is for established protocols. Only callable by Auths.
Parameters
| Name | Type | Description |
|---|---|---|
| userClasses_ | struct Structs.AddressUint256 | struct array of uint256 value to assign for each user address |
updateUserSupplyConfigs
function updateUserSupplyConfigs(struct Structs.UserSupplyConfig[] userSupplyConfigs_) externalsets user supply configs per token basis. Eg: with interest or interest-free and automated limits. Only callable by Auths.
Parameters
| Name | Type | Description |
|---|---|---|

updateUserBorrowConfigs
function updateUserBorrowConfigs(struct Structs.UserBorrowConfig[] userBorrowConfigs_) externalsetting user borrow configs per token basis. Eg: with interest or interest-free and automated limits. Only callable by Auths.
Parameters

pauseUser
function pauseUser(address user_, address[] supplyTokens_, address[] borrowTokens_) externalpause operations for a particular user in class 0 (class 1 users can't be paused by guardians). Only callable by Guardians.
Parameters
| Name | Type | Description |
|---|---|---|
| user_ | address | address of user to pause operations for |
| supplyTokens_ | address | token addresses to pause withdrawals for |
| borrowTokens_ | address | token addresses to pause borrowings for |
unpauseUser
function unpauseUser(address user_, address[] supplyTokens_, address[] borrowTokens_) externalunpause operations for a particular user in class 0 (class 1 users can't be paused by guardians). Only callable by Guardians.
Parameters
| Name | Type | Description |

collectRevenue
function collectRevenue(address[] tokens_) externalcollects revenue for tokens to configured revenueCollector address.
Note that this can revert if token balance is < revenueAmount (utilization > 100%)
Parameters
| Name | Type | Description |
|---|---|---|
| tokens_ | address | array of tokens to collect revenue for |
updateExchangePrices
function updateExchangePrices(address[] tokens_) external returns (uint256[] supplyExchangePrices_, uint256[] borrowExchangePrices_)gets the current updated exchange prices for n tokens and updates all prices, rates related data in storage.
Parameters
| Name | Type | Description |
|---|---|---|
| tokens_ | address | tokens to update exchange prices for |
Return Values
| Name | Type | Description |
|---|---|---|
| supplyExchangePrices_ | uint256 | new supply rates of overall system for each token |
| borrowExchangePrices_ | uint256 | new borrow rates of overall system for each token |
operate
function operate(address token_, int256 supplyAmount_, int256 borrowAmount_, address withdrawTo_, address borrowTo_, bytes callbackData_) external payable returns (uint256 memVar3_, uint256 memVar4_)Single function which handles supply, withdraw, borrow & payback
_to trigger skipping in / out transfers when in&out amounts balance themselves out (gas optimization):
- supply(+) == borrow(+), withdraw(-) == payback(-).
withdrawTo_/borrowTo_must be msg.sender (protocol)callbackData_MUST be encoded so that "from" address is at last 20 bytes (if this optimization is desired), also for native token operations where liquidityCallback is not triggered! from address must come at last position if there is more data. I.e. encode like: abi.encode(otherVar1, otherVar2, FROMADDRESS). Note dynamic types used with abi.encode come at the end so if dynamic types are needed, you must use abi.encodePacked to ensure the from address is at the end.
Parameters
| Name | Type | Description |
|---|---|---|
| token_ | address | address of token (0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE for native) |
| supplyAmount_ | int256 | if +ve then supply, if -ve then withdraw, if 0 then nothing |
| borrowAmount_ | int256 | if +ve then borrow, if -ve then payback, if 0 then nothing |
| withdrawTo_ | address | if withdrawal then to which address |
| borrowTo_ | address | if borrow then to which address |
| callbackData_ | bytes | callback data passed to liquidityCallback method of protocol |
Return Values
| Name | Type | Description |
|---|---|---|
| memVar3_ | uint256 | updated supplyExchangePrice |
| memVar4_ | uint256 | updated borrowExchangePrice |
