#Overview This project implements a staking smart contract system using Solidity and Hardhat. Users can stake ERC20 tokens and earn rewards over time. The system includes a main Staking contract, along with separate ERC20 tokens for staking and rewards.

𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬 Stake ERC20 tokens Earn rewards based on staking duration and amount Withdraw staked tokens Claim accumulated rewards Configurable reward rate

𝐂𝐥𝐨𝐧𝐞 𝐭𝐡𝐞 𝐫𝐞𝐩𝐨𝐬𝐢𝐭𝐨𝐫𝐲: git clone cd

𝐈𝐧𝐬𝐭𝐚𝐥𝐥 𝐝𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐢𝐞𝐬: npm install

𝐂𝐨𝐦𝐩𝐢𝐥𝐞 𝐭𝐡𝐞 𝐜𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐬: npx hardhat compile

𝐑𝐮𝐧 𝐭𝐞𝐬𝐭𝐬: npx hardhat test

𝐑𝐮𝐧𝐧𝐢𝐧𝐠 𝐓𝐞𝐬𝐭𝐬: The project includes a comprehensive test suite. To run the tests: npx hardhat test This will run all tests in the test/ directory. Deployment 𝐓𝐨 𝐝𝐞𝐩𝐥𝐨𝐲 𝐭𝐡𝐞 𝐜𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐬 𝐭𝐨 𝐚 𝐧𝐞𝐭𝐰𝐨𝐫𝐤:

Set up your network configuration in hardhat.config.js Create a deployment script in the scripts/ directory 𝐑𝐮𝐧 𝐭𝐡𝐞 𝐝𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭 𝐬𝐜𝐫𝐢𝐩𝐭: npx hardhat run scripts/deploy.js --network

𝐂𝐨𝐧𝐭𝐫𝐚𝐜𝐭 𝐃𝐞𝐭𝐚𝐢𝐥𝐬 Staking.sol The main contract that handles staking, withdrawing, and reward distribution.

𝐊𝐞𝐲 𝐟𝐮𝐧𝐜𝐭𝐢𝐨𝐧𝐬: Stake(uint256 _amount): Stake tokens Withdraw(uint256 _amount): Withdraw staked tokens ClaimReward(): Claim accumulated rewards

RewardToken.sol and StakedToken.sol ERC20 token contracts for the reward and staked tokens respectively. Security Considerations

The contract uses OpenZeppelin's SafeMath library to prevent overflow/underflow issues. Token transfers are checked for success to prevent silent failures. The contract includes access control to prevent unauthorized actions.

𝐇𝐨𝐰𝐞𝐯𝐞𝐫, 𝐛𝐞𝐟𝐨𝐫𝐞 𝐝𝐞𝐩𝐥𝐨𝐲𝐢𝐧𝐠 𝐭𝐨 𝐚 𝐥𝐢𝐯𝐞 𝐧𝐞𝐭𝐰𝐨𝐫𝐤:

Conduct a thorough code review. Consider getting a professional audit, especially if significant value will be managed by the contract. Test extensively on a testnet before deploying to mainnet.
