Methods

CONTRACT_ADMIN_ROLE

function CONTRACT_ADMIN_ROLE() view returns(bytes32)

a role used with a subset of governor permissions for this contract only

Returns
Param Type Notes
bytes32

balance

function balance() view returns(uint256)

returns the balance in USD

Returns
Param Type Notes
uint256

balanceReportedIn

function balanceReportedIn() pure returns(address)

Curve/Convex deposits report their balance in USD

Returns
Param Type Notes
address

core

function core() view returns(address)

address of the Core contract referenced

Returns
Param Type Notes
address ICore implementation address

curvePool

function curvePool() view returns(address)

The Curve pool to deposit in

Returns
Param Type Notes
address

deposit

function deposit() nonpayable

deposit tokens into the Curve pool, then stake the LP tokens on Convex to earn rewards.

exitPool

function exitPool() nonpayable

Exit the Curve pool by removing liquidity. The contract will hold tokens in proportion to what was in the Curve pool at the time of exit, i.e. if the pool is 20% FRAX 60% FEI 20% alUSD, and the contract has 10M$ of liquidity, it will exit the pool with 2M FRAX, 6M FEI, 2M alUSD.

fei

function fei() view returns(address)

address of the Fei contract referenced by Core

Returns
Param Type Notes
address IFei implementation address

feiBalance

function feiBalance() view returns(uint256)

fei balance of contract

Returns
Param Type Notes
uint256 fei amount held

isContractAdmin

function isContractAdmin(address) view returns(bool)

returns whether a given address has the admin role for this contract

Params
Param Type Notes
_admin address
Returns
Param Type Notes
bool

maxSlippageBasisPoints

function maxSlippageBasisPoints() view returns(uint256)

maximum slippage accepted during deposit / withdraw, expressed in basis points (100% = 10_000).

Returns
Param Type Notes
uint256

pause

function pause() nonpayable

set pausable methods to paused

paused

function paused() view returns(bool)

Returns true if the contract is paused, and false otherwise.

Returns
Param Type Notes
bool

resistantBalanceAndFei

function resistantBalanceAndFei() view returns(uint256,uint256)

returns the resistant balance in USD and FEI held by the contract

Returns
Param Type Notes

resistantFei uint256

setContractAdminRole

function setContractAdminRole(bytes32) nonpayable

sets a new admin role for this contract

Params
Param Type Notes
newContractAdminRole bytes32

setCore

function setCore(address) nonpayable

set new Core reference address

Params
Param Type Notes
newCore address the new core address

tribe

function tribe() view returns(address)

address of the Tribe contract referenced by Core

Returns
Param Type Notes
address IERC20 implementation address

tribeBalance

function tribeBalance() view returns(uint256)

tribe balance of contract

Returns
Param Type Notes
uint256 tribe amount held

unpause

function unpause() nonpayable

set pausable methods to unpaused

withdraw

function withdraw(address,uint256) nonpayable

Exit the Curve pool by removing liquidity in one token. If FEI is in the pool, pull FEI out of the pool. If FEI is not in the pool, exit in the first token of the pool. To exit without chosing a specific token, and minimize slippage, use exitPool().

Params
Param Type Notes
to address
amountUnderlying uint256

withdrawERC20

function withdrawERC20(address,address,uint256) nonpayable

withdraw ERC20 from the contract

Params
Param Type Notes
token address address of the ERC20 to send
to address address destination of the ERC20
amount uint256 quantity of ERC20 to send

withdrawETH

function withdrawETH(address,uint256) nonpayable

withdraw ETH from the contract

Params
Param Type Notes
to address address to send ETH
amountOut uint256 amount of ETH to send

withdrawOneCoin

function withdrawOneCoin(uint256,address,uint256) nonpayable

Exit the Curve pool by removing liquidity in one token. Note that this method can cause slippage. To exit without slippage, use the exitPool() method.

Params
