TokenStaker is a full-stack decentralized application (DApp) built on the Ethereum blockchain that allows users to stake their tokens (StakeToken) and earn rewards (RewardToken) over time. This project demonstrates a secure and transparent staking mechanism, providing incentives for token holders to participate in the network.
The FlashLoan contract aims to capitalize on the temporary price discrepancies that can occur between different trading pairs on PancakeSwap. It achieves this by:
Borrowing a significant amount of a token (e.g., BUSD) from a PancakeSwap liquidity pool using a flash loan.
Executing a series of trades across different token pairs (e.g., BUSD -> CROX -> CAKE -> BUSD) to take advantage of price differences.
Repaying the flash loan with a portion of the acquired funds.
If the trades result in a net profit, the remaining funds are transferred to the contract owner as profit.
Staking: Users can stake their StakeToken (STK) to earn rewards.
Reward Distribution: Rewards (RWT) are distributed proportionally to the amount staked and the staking duration.
Reward Rate: A constant reward rate ensures predictable earnings.
Withdrawal: Users can withdraw their staked tokens and accumulated rewards.
User Interface: An intuitive front-end allows users to easily manage their staking activities.
Security: The project incorporates the OpenZeppelin library for secure smart contract development.
Blockchain: Ethereum (Chosen for its smart contract capabilities and established DeFi ecosystem)
Smart Contracts: Language: Solidity (>=0.8.2 <0.9.0) Staking.sol:
Manages the staking logic: staking, withdrawing, reward calculation, and distribution.
stake(uint amount): Allows users to stake their STK tokens.
withdrawStakedTokens(uint amount): Allows users to withdraw staked STK tokens.
getReward(): Allows users to claim accumulated RWT rewards.
StakeToken.sol: ERC-20 token contract representing the stakeable asset (STK).
RewardToken.sol: ERC-20 token contract representing the reward token (RWT).
Frontend: Framework: React (Presumably, based on the .jsx extension)
Components: App.jsx: Main application component, manages UI and user interactions.
Wallet.jsx: Handles wallet connection and user authentication.
Navigation.jsx: Provides navigation between different sections of the DApp.
DisplayPanel.jsx: Displays staked amount, reward rate, and earned rewards.
TokenApproval.jsx, StakeAmount.jsx: Components for staking.
Withdraw.jsx: Component for withdrawing staked tokens and rewards.
