MasterChef is the smart contract that offers staking USC in exchange for USC with adjustable yearly ROI.

Overview

Contract: MasterChef.sol

MasterChef is an Upgradeable smart contract that allows a user to stake their USC token for USC rewards. The ROI per year starts at 10% per year and can't be adjusted.

Dependencies

• Ownable: Allows the contract admin to perform privileged actions.

How it works

The MasterChef will be provided with the address of the staking token (USC token) and the initial ROI per year (also regarded as the minimum ROI per year) during its initialization process.

The ROI will be provided at initialization time and is equal to 10% per year. For example, if you stake 1000 USC token and after 365 days (calculated by blocktime difference), you'll get 100 USC as the reward.

When the smart contract is paused, the following functions can't be called: deposit, getReward.

The withdraw function will work at all times even if the smart contract is paused, this ensures that user can exit at anytime.
