Best Practices

Security Warning: Always audit smart contracts before deploying to mainnet. Consider using established security frameworks and getting professional audits for production applications.

Start with simple smart contracts and gradually increase complexity
Always test on testnets before mainnet deployment
Understand gas optimization techniques
Learn about common smart contract vulnerabilities
Keep up with the rapidly evolving blockchain ecosystem
