Overview

This project is a smart contract system built for secure token staking and reward management on the Ethereum blockchain. It provides essential components for handling staking operations, managing rewards, and ensuring the security of staked assets. The system is designed to be robust, leveraging mathematical precision for reward calculations and secure vaults for asset protection.

Key Components

• StakeManager: This contract handles the core staking operations. It is responsible for managing the staking process, calculating rewards, and tracking expired staking periods using advanced mathematical calculations. The contract utilizes OpenZeppelin’s ERC20 and math utilities to ensure accuracy and security.
• StakeVault: This contract is responsible for securing user stakes. It facilitates the interactions between users and the staking system by ensuring that staked tokens are properly managed. The vault communicates with StakeManager to handle staking and unstaking operations while ensuring the safety of funds.

Features

• Secure Staking: Users can stake tokens securely, with all interactions governed by the StakeVault and managed by StakeManager. StakeVault is actually owned by the user, and is the only account allowed to perform actions on it, where it store the staked tokens. StakeVault recognizes the validity of the StakeVault codehash to allow interacting with it, knowing that the code actually holds the tokens when it should.
• Reward Estimation: The system provides accurate reward estimation, using mathematical formulas to calculate earnings based on staking time and amount.
• Management of Expired Stakes: StakeManager tracks and manages expired staking periods, allowing for the efficient handling of staking cycles.
• Integration with ERC20 Tokens: Built on top of the OpenZeppelin ERC20 token standard, the system ensures compatibility with any ERC20-compliant token.

Installation

To install the dependencies for this project, run the following command:

pnpm install

Usage

Staking Tokens

To stake tokens, the StakeVault contract interacts with the StakeManager. You can call the stake function from StakeVault with the desired amount and duration.

function stake(uint256 _amount, uint256 _time) external onlyOwner;

Managing Rewards

Rewards are calculated based on the staking period and amount. StakeManager provides functions to manage and track the reward process.

Security

The system is designed to protect staked tokens and ensure users’ assets remain safe throughout the staking process.
