MaxWithdrawalSlippageUpdated​

event MaxWithdrawalSlippageUpdated(uint256 _prevMaxSlippagePercentage, uint256 _newMaxSlippagePercentage)

InitConfig​

struct InitConfig {
  address cvxDepositorAddress;
  address metapoolAddress;
  address metapoolMainToken;
  address cvxRewardStakerAddress;
  address metapoolLPToken;
  uint256 cvxDepositorPTokenId;
}

cvxDepositorAddress​

address cvxDepositorAddress

cvxRewardStakerAddress​

address cvxRewardStakerAddress

cvxDepositorPTokenId​

uint256 cvxDepositorPTokenId

metapool​

contract ICurveMetaPool metapool

metapoolMainToken​

contract IERC20 metapoolMainToken

metapoolLPToken​

contract IERC20 metapoolLPToken

metapoolAssets​

address[] metapoolAssets

maxWithdrawalSlippage​

uint256 maxWithdrawalSlippage

crvCoinIndex​

uint128 crvCoinIndex

mainCoinIndex​

uint128 mainCoinIndex

initialize​

function initialize(address[] _rewardTokenAddresses, address[] _assets, address[] _pTokens, struct BaseConvexMetaStrategy.InitConfig initConfig) external

Initializer for setting up strategy internal state. This overrides the InitializableAbstractStrategy initializer as Curve strategies don't fit well within that abstraction.

Parameters​

NameTypeDescription
_rewardTokenAddressesaddress[]Address of CRV & CVX
_assetsaddress[]Addresses of supported assets. MUST be passed in the same order as returned by coins on the pool contract, i.e. DAI, USDC, USDT
_pTokensaddress[]Platform Token corresponding addresses
initConfigstruct BaseConvexMetaStrategy.InitConfigVarious addresses and info for initialization state

checkBalance​

function checkBalance(address _asset) public view virtual returns (uint256 balance)

Get the total asset value held in the platform

Parameters​

NameTypeDescription
_assetaddressAddress of the asset

Return Values​

NameTypeDescription
balanceuint256Total value of the asset in the platform

_calcCurveMetaTokenAmount​

function _calcCurveMetaTokenAmount(uint128 _coinIndex, uint256 _amount) internal returns (uint256 requiredMetapoolLP)

This function is completely analogous to _calcCurveTokenAmount[BaseCurveStrategy] and just utilizes different Curve (meta)pool API

_approveBase​

function _approveBase() internal

_getMetapoolCoinIndex​

function _getMetapoolCoinIndex(address _asset) internal view returns (uint128)

Get the index of the coin

setMaxWithdrawalSlippage​

function setMaxWithdrawalSlippage(uint256 _maxWithdrawalSlippage) external

Sets max withdrawal slippage that is considered when removing liquidity from Metapools.

Parameters​

NameTypeDescription
_maxWithdrawalSlippageuint256Max withdrawal slippage denominated in wad (number with 18 decimals): 1e18 == 100%, 1e16 == 1% IMPORTANT Minimum maxWithdrawalSlippage should actually be 0.1% (1e15) for production usage. Contract allows as low value as 0% for confirming correct behavior in test suite.

collectRewardTokens​

function collectRewardTokens() external

Collect accumulated CRV and CVX and send to Harvester.

_max​

function _max(int256 a, int256 b) internal pure returns (int256)

Returns the largest of two numbers int256 version
