🎯 Secure, Efficient, and Reliable Smart Contracts

🔐 Security First

  • Use Reentrancy Guards to prevent recursive calls (e.g., DAO hack).
  • Validate All Inputs with strict checks to avoid overflow/underflow errors.
  • Minimize External Calls to reduce attack surfaces; prefer internal functions.
  • Implement Access Control via roles (e.g., OpenZeppelin's Access Control).

🔄 Upgradability Strategies

  • Use Proxy Patterns (e.g., Transparent Proxy) for logic upgrades.
  • Avoid Hardcoded Addresses; deploy upgradeable contracts via standardized frameworks.
  • Test Upgrade Paths thoroughly to ensure compatibility with new versions.

🧪 Testing & Verification

  • Write Unit Tests for all critical functions (e.g., using Truffle).
  • Perform Formal Verification with tools like Slither or Certora.
  • Simulate Edge Cases (e.g., zero balances, time-based conditions).

🚀 Efficiency Tips

  • Optimize Gas Usage by avoiding loops in critical paths.
  • Use Libraries for Common Functions (e.g., OpenZeppelin's Utils).
  • Leverage State Channels for off-chain computations.
