Introduction
As part of my EtherAuthority Web3+AI Internship, I developed and deployed a DeFi Staking Platform on SecureChain AI (SCAI) Mainnet.
This project provided hands-on experience in Solidity smart contract development, blockchain integration, MetaMask wallet connectivity, and decentralized application deployment.

💡 Project Overview
The DeFi Staking Platform allows users to stake ETH securely and earn rewards through a decentralized staking mechanism.
Users can:
- Connect MetaMask Wallet
- Stake ETH
- Withdraw Staked ETH
- Claim Rewards
- View Wallet Balance
- Track Staking Activity

📜 Smart Contract Features
Stake ETH
Users can deposit ETH into the staking contract and start earning rewards.
Withdraw ETH
Users can withdraw their staked ETH whenever needed.
Reward Calculation
The contract calculates rewards based on staking activity.
Claim Rewards
Users can claim accumulated rewards directly from the platform.
Balance Tracking
The smart contract maintains staking balances and reward information for each wallet.
🖥️ Frontend Features
Built with React.js, Vite, and Ethers.js.
