FAQs

Consider what your project needs. Ethereum is good for decentralized apps, while Binance Smart Chain is better for lower fees. Look into the security features and community support of each platform. Choose one that best fits your project's goals.
Look for previous projects related to your needs, like smart contracts or NFT minting. Check how well the projects worked and if they are active now. Pay attention to technical details and the complexity of past work. This shows the developer's expertise.
Break down the project into smaller tasks, like developing smart contracts or integrating wallets. Set clear milestones with specific outcomes. Describe what success looks like for each step. This helps both you and the developer stay on track.
Include all development phases like research, coding, testing, and deployment. Allocate time for unexpected changes or improvements. Ensure each phase has a start and end date. A clear timeline keeps everyone aligned and focused.
Ask them about past experiences with secure coding practices. See if they are up-to-date with current blockchain security threats. Look for participation in security audits or bug bounty programs. Their history with security can reduce risks in your project.
Unit tests confirm each part works as it should. Integration tests ensure all parts work together properly. Use stress tests to see how well the system handles a lot of activity. Testing methods should match the requirements of your project.
Platforms like Slack or Microsoft Teams are good for quick chats. Use GitHub for tracking code changes and issues. Video calls can help with more detailed discussions. Choose tools that make communication easy and clear.
There's a project manager who oversees everything. Developers write and test the code. Designers work on user interfaces and experiences. Each role contributes to the project's success. Recognizing these roles helps with teamwork and setting expectations.
Certifications can show a developer is skilled and knowledgeable. They're not the only proof of ability, though. Look at their real-world experience and project success. Both certifications and experience can show their talent.
Discuss project goals, timelines, and key milestones. Define the scope and limits of the project clearly. Talk about communication and how updates will be shared. A well-structured meeting helps ensure everyone is on the same page from the start.
