QuantumFinance Token (QFT) - A DeFi ERC20 Token

QuantumFinance Token (QFT) is a custom ERC20 token deployed on the Ethereum-compatible Arbitrum network. It comes with advanced DeFi features like token burning and staking rewards.

Features

• Token Burning: 2% of every transaction is automatically burned, reducing the total supply over time.
• Staking Rewards: Holders can stake their tokens and earn a 5% annual reward rate.
• Adjustable Rates: The owner can adjust the burn and reward rates with set limits for flexibility and security.

Smart Contract Details

• Token Name: QuantumFinance Token
• Token Symbol: QFT
• Initial Supply: 1,000,000 QFT (minted to the contract creator)
• Burn Rate: 2% (default)
• Reward Rate: 5% per year (default)

Core Functions

1. transfer(address recipient, uint256 amount)

   • Transfers tokens and applies the burn rate.
   • Emits a Burned event for transparency.

2. stakeTokens(uint256 amount)

   • Allows users to stake their tokens for rewards.
   • Emits a Staked event.

3. unstakeTokens()

   • Allows users to unstake tokens and claim their rewards.
   • Emits an Unstaked event.

4. setBurnRate(uint256 newBurnRate)

   • Allows the contract owner to change the burn rate (up to 10%).

5. setRewardRate(uint256 newRewardRate)

   • Allows the contract owner to change the reward rate (up to 20%).

Deployment Instructions

1. Open Remix IDE.
2. Create a new file and paste the contract code.
3. Compile the contract using Solidity version 0.8.24.
4. Deploy the contract to an Ethereum-compatible test network (e.g., Arbitrum testnet).
5. Interact with the contract using Remix’s interface.

Technologies Used

• Solidity 0.8.24: Smart contract programming language.
• OpenZeppelin: Industry-standard library for secure smart contracts.
• Remix IDE: Development environment for smart contract deployment.
