Project Background

The Solidity smart contract for a token called “Sustainix Renewable” (SXR). This contract extends the ERC20 standard with additional features such as burnable tokens, fee mechanisms, swap thresholds, and automated market maker (AMM) management.

Here’s a brief overview of the contract features and structure:

• ERC20 Standard and Burnable Tokens: Inherits from `ERC20` and `ERC20Burnable`.
• Ownership:
  • Uses `Ownable2Step` to manage ownership.
  • The `Initializable` ensures that certain functions run only once after deployment.
• Fees and Liquidity:
  • Supports three types of fees: buy, sell, and transfer.
  • Fees can be allocated for research and liquidity.
  • Uses UniswapV2 for liquidity operations.
  • Exclusions: Addresses can be excluded from fees and trade limits.
• Trading Limits:
  • Enforces maximum buy and sell amounts.
  • Implements trade cooldown periods to prevent rapid trades.
• Swap and Liquify:
  • Automatically swaps tokens for ETH and adds liquidity.
  • Supports adding liquidity from leftover tokens.
• Error Handling: Custom error messages for various validation checks.

This contract is designed to handle various aspects of an ERC20 token, including fees, liquidity management, and trading restrictions, making it suitable for a decentralized finance (DeFi) application.
