A comprehensive smart contract ecosystem for conducting Initial Coin Offerings (ICOs), token management, and DeFi operations on EVM-compatible blockchains.
This project provides a complete suite of smart contracts for launching and managing cryptocurrency tokens with advanced features including:
- Token Presale System: Modular presale contracts with role-based access control for conducting secure token sales
- ERC20 Token with Tax Mechanism: Custom token implementation featuring buy/sell taxes, anti-whale protection, and automatic liquidity provision through Uniswap
- Staking Platform: Flexible staking contracts supporting multiple duration tiers, dynamic APR adjustments, and reward distribution
- Vesting Mechanisms: Linear and monthly vesting schedules for controlled token distribution
- DeFi Features: Yield farming and vault contracts for enhanced token utility
- ERC20 compliant token with extended functionality
- Anti-whale mechanism to prevent large wallet accumulation
- Blacklist/whitelist system for address management
- Automatic tax distribution to charity and development wallets
- Uniswap V2 integration for decentralized trading
- Secure token sale management
- Role-based access control (Admin, Owner)
- Modular architecture for flexibility
- Support for multiple payment tokens
- Multiple staking duration options (30, 90, 180, 270 days)
- Variable APR rates
- Compound interest calculations
- Emergency withdrawal functionality
- Real-time reward claiming
