Daily Login Rewards

The Daily Login Rewards Smart Contract is designed to incentivize user activity by providing token rewards for logging in daily. The contract maintains a record of each user's last reward claim and enforces a 24-hour cooldown before the next claim. This prevents abuse and ensures fair distribution of rewards. Users can call the claimReward() function to receive a fixed amount of tokens once per day. The contract operates without external dependencies, making it lightweight and efficient for Ethereum-based blockchain applications.
