Smart Contracts Overview

The VLR staking contract and all unique E-VLR staking contracts have over 90% of common code in common. The only differences in function headers enable a distribution of a rewards basket in exchanged for staked VLR, as opposed to a single token used for both inputs and outputs of all E-VLR staking contracts.

event RewardsDistributed(uint256[] indexed totalDistributed, address[] indexed addressesOfDistributedTokens, uint256 indexed timeOfDistribution );
At the time of rewards distribution, we log the basket of tokens distributed and the respective quantity of tokens distributed.

stake
function stake(uint256 _stakedVlrAmount) 
        external 
        returns (
                uint256 mtcFeePaid, 
                uint256 charityFeePaid, 
                uint256 burnFeePaid, 
                uint256 stakingFeePaid, 
                uint256 svlrMinted
        );
Contributes _stakedVlrAmount to the contract, creating svlrMinted equal to that amount less mtcFeePaid, charityFeePaid, burnFeePaid, and stakingFeePaid.
 
unstake
function unstake(uint256 _unstakedAmount)
        external 
        returns (
                uint256 mtcFeePaid, 
                uint256 charityFeePaid, 
                uint256 burnFeePaid, 
                uint256 stakingFeePaid, 
                uint256 vlrReturned,
                uint256 vlrRewardsReturned
        );
Removes _unstakedAmount and returns vlrReturned equal to that amount less mtcFeePaid, charityFeePaid, burnFeePaid, and stakingFeePaid plus staking rewards equal to vlrRewardsReturned.
