A smart contract application that allows users to stake ERC20 tokens and earn ETH rewards over fixed staking periods. Built with Solidity and audited with comprehensive test coverage using Foundry.
- Token Staking: Users can deposit a fixed amount of tokens to start staking
- Reward Distribution: Earn ETH rewards after completing staking periods
- Flexible Withdrawal: Withdraw staked tokens at any time
- Owner Control: Contract owner can manage staking periods and fund rewards
- ERC20 Integration: Uses OpenZeppelin's secure ERC20 implementation
Main contract handling staking operations, reward distribution, and configuration.
Key Functions:
depositTokens(uint256 amount)- Stake tokenswithdrawTokens()- Withdraw staked tokensclaimRewards()- Claim accumulated ETH rewardssetNewStakingPeriod(uint256 period)- Owner function to update staking durationreceive()- Accept ETH for reward funding (owner only)
Key Features:
- Fixed deposit amount enforcement
- Time-based reward eligibility
- Secure token transfers with OpenZeppelin's ERC20
- Owner access control via Ownable pattern
Simple ERC20 token contract used as the staking asset.
Key Functions:
mint(uint256 amount)- Mint new tokens to caller
Note: In production, consider adding access control to restrict minting privileges.
