Migrating from 2.0 to 2.1 Smart Contracts

MultiVault​

Last Active Epoch is now User Epoch History​

The lastActiveEpoch mapping in the MultiVault contract has been replaced with a more comprehensive userEpochHistory mapping. This new mapping tracks up 3 epochs in which each user has been active.

Previous:

mapping(address => uint256) public lastActiveEpoch;

Current:

mapping(address => uint256[3]) public userEpochHistory;

To get the last active epoch of a user, you can now use the following function:

function getUserLastActiveEpoch(address user) external view returns (uint256) {
    return userEpochHistory[user][0];
}

MultiVault Config​

The GeneralConfig struct has been updated to include a new parameter feeThreshold and remove the decimalPrecision parameter.

struct GeneralConfig {
    address admin;
    address protocolMultisig;
    uint256 feeDenominator;
    address trustBonding;
    uint256 minDeposit;
    uint256 minShare;
    uint256 atomDataMaxLength;
    uint256 feeThreshold;
}

Previously the GeneralConfig struct contained the decimalPrecision parameter that has been removed in this version.

struct GeneralConfig {
    address admin;
    address protocolMultisig;
    uint256 feeDenominator;
    address trustBonding;
    uint256 minDeposit;
    uint256 minShare;
    uint256 atomDataMaxLength;
    uint256 decimalPrecision;
}

The getGeneralConfig function now reflects the updated GeneralConfig struct:

function getGeneralConfig() external view returns (GeneralConfig memory);

Triple Config​

The tripleConfig struct has been updated to include only two parameters: tripleCreationProtocolFee and atomDepositFractionForTriple.

struct TripleConfig {
    uint256 tripleCreationProtocolFee;
    uint256 atomDepositFractionForTriple;
}

Previously the tripleConfig struct contained totalAtomDepositsOnTripleCreation parameters that have been removed in this version.

struct TripleConfig {
    uint256 tripleCreationProtocolFee;
    uint256 totalAtomDepositsOnTripleCreation;
    uint256 atomDepositFractionForTriple;
}

The getTripleConfig return value now reflects the updated TripleConfig struct:

getTripleConfig() external view returns (TripleConfig memory);

Bonding Curves

Offset Progressive Curve​

The OffsetProgressiveCurve.sol contract no longer auto-scales the slope parameter during initialization. The slope parameter should now be provided in its scaled form.

Previous:

SLOPE=2;

Current:

SLOPE=2e18;
