Writing smart contracts requires attention to detail, especially when it comes to security and efficiency. Here are some best practices:
- Avoid Overflow/Underflow: Use Solidity’s
SafeMath
library to prevent arithmetic overflow and underflow. - Use Modifiers for Access Control: Restrict who can execute certain functions using modifiers like
onlyOwner
. - Gas Optimization: Write efficient code to minimize gas costs. Avoid unnecessary computations and storage operations.
- Audit and Test: Thoroughly test your contract and consider an external audit before deploying on the mainnet.
