Functions

updateAuths

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.

function updateAuths(AdminModuleStructs.AddressBool[] calldata authsStatus_) external;

Parameters

NameTypeDescription
authsStatus_AdminModuleStructs.AddressBool[]array of structs setting allowed status for an address. status true => add auth, false => remove auth

updateGuardians

adds/removes guardians. Only callable by Governance.

function updateGuardians(AdminModuleStructs.AddressBool[] calldata guardiansStatus_) external;

Parameters

NameTypeDescription
guardiansStatus_AdminModuleStructs.AddressBool[]array of structs setting allowed status for an address. status true => add guardian, false => remove guardian

updateRevenueCollector

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

function updateRevenueCollector(address revenueCollector_) external;

Parameters

NameTypeDescription
revenueCollector_addressnew revenue collector address

changeStatus

changes current status, e.g. for pausing or unpausing all user operations. Only callable by Auths.

function changeStatus(uint256 newStatus_) external;

Parameters

NameTypeDescription
newStatus_uint256new status status = 2 -> pause, status = 1 -> resume.

updateRateDataV1s

update tokens rate data version 1. Only callable by Auths.

function updateRateDataV1s(AdminModuleStructs.RateDataV1Params[] calldata tokensRateData_) external;

Parameters

NameTypeDescription
tokensRateData_AdminModuleStructs.RateDataV1Params[]array of RateDataV1Params with rate data to set for each token

updateRateDataV2s

update tokens rate data version 2. Only callable by Auths.

function updateRateDataV2s(AdminModuleStructs.RateDataV2Params[] calldata tokensRateData_) external;

Parameters

NameTypeDescription
tokensRateData_AdminModuleStructs.RateDataV2Params[]array of RateDataV2Params with rate data to set for each token

updateTokenConfigs

updates token configs: fee charge on borrowers interest & storage update utilization threshold. Only callable by Auths.

function updateTokenConfigs(AdminModuleStructs.TokenConfig[] calldata tokenConfigs_) external;

Parameters

NameTypeDescription
tokenConfigs_AdminModuleStructs.TokenConfig[]contains token address, fee & utilization threshold

updateUserClasses

updates user classes: 0 is for new protocols, 1 is for established protocols. Only callable by Auths.

function updateUserClasses(AdminModuleStructs.AddressUint256[] calldata userClasses_) external;

Parameters

NameTypeDescription
userClasses_AdminModuleStructs.AddressUint256[]struct array of uint256 value to assign for each user address

updateUserSupplyConfigs

sets user supply configs per token basis. Eg: with interest or interest-free and automated limits. Only callable by Auths.

function updateUserSupplyConfigs(AdminModuleStructs.UserSupplyConfig[] memory userSupplyConfigs_) external;

Parameters

NameTypeDescription
userSupplyConfigs_AdminModuleStructs.UserSupplyConfig[]struct array containing user supply config, see UserSupplyConfig struct for more info

updateUserBorrowConfigs

setting user borrow configs per token basis. Eg: with interest or interest-free and automated limits. Only callable by Auths.

function updateUserBorrowConfigs(AdminModuleStructs.UserBorrowConfig[] memory userBorrowConfigs_) external;

Parameters

NameTypeDescription
userBorrowConfigs_AdminModuleStructs.UserBorrowConfig[]struct array containing user borrow config, see UserBorrowConfig struct for more info

pauseUser

pause operations for a particular user in class 0 (class 1 users can't be paused by guardians). Only callable by Guardians.

function pauseUser(address user_, address[] calldata supplyTokens_, address[] calldata borrowTokens_) external;

Parameters

NameTypeDescription
user_addressaddress of user to pause operations for
supplyTokens_address[]token addresses to pause withdrawals for
borrowTokens_address[]token addresses to pause borrowings for

unpauseUser

unpause operations for a particular user in class 0 (class 1 users can't be paused by guardians). Only callable by Guardians.

function unpauseUser(address user_, address[] calldata supplyTokens_, address[] calldata borrowTokens_) external;

Parameters

NameTypeDescription
user_addressaddress of user to unpause operations for
supplyTokens_address[]token addresses to unpause withdrawals for
borrowTokens_address[]token addresses to unpause borrowings for

collectRevenue

collects revenue for tokens to configured revenueCollector address.

Note that this can revert if token balance is < revenueAmount (utilization > 100%)

function collectRevenue(address[] calldata tokens_) external;

Parameters

NameTypeDescription
tokens_address[]array of tokens to collect revenue for

updateExchangePrices

gets the current updated exchange prices for n tokens and updates all prices, rates related data in storage.

function updateExchangePrices(address[] calldata tokens_)
    external
    returns (uint256[] memory supplyExchangePrices_, uint256[] memory borrowExchangePrices_);

Parameters

NameTypeDescription
tokens_address[]tokens to update exchange prices for

Returns

NameTypeDescription
supplyExchangePrices_uint256[]new supply rates of overall system for each token
borrowExchangePrices_uint256[]new borrow rates of overall system for each token

operate

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, FROM_ADDRESS). 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.*
function operate(
    address token_,
    int256 supplyAmount_,
    int256 borrowAmount_,
    address withdrawTo_,
    address borrowTo_,
    bytes calldata callbackData_
) external payable returns (uint256 memVar3_, uint256 memVar4_);

Parameters

NameTypeDescription
token_addressaddress of token (0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE for native)
supplyAmount_int256if +ve then supply, if -ve then withdraw, if 0 then nothing
borrowAmount_int256if +ve then borrow, if -ve then payback, if 0 then nothing
withdrawTo_addressif withdrawal then to which address
borrowTo_addressif borrow then to which address
callbackData_bytescallback data passed to liquidityCallback method of protocol

Returns

NameTypeDescription
memVar3_uint256updated supplyExchangePrice
memVar4_uint256updated borrowExchangePrice
