FAQs

What skills should I look for when hiring a blockchain developer?

Look for developers who know smart contracts really well. They should also understand different blockchain platforms like Ethereum or Hyperledger. Good developers also keep up with the latest trends and security practices.

How can I ensure the blockchain developer understands my project needs?

It's important to clearly explain your project's goals. Share detailed requirements and examples if possible. Ask the developer to repeat these back to you in their own words to check understanding.

What steps should I take to define project deliverables clearly?

Break down your project into small tasks with deadlines. Make sure each task has a clear goal and expected outcome. Write everything down so there is no confusion later.

What questions can help me gauge a developer's experience with blockchain?

Ask about their past projects related to your industry. Inquire about challenges they faced and how they solved them. Also, ask for demos or code samples if available.

What are the best practices for managing timelines with a freelance blockchain developer?

Set milestones and regular check-ins. This keeps projects on track and allows for adjustments if needed. Be flexible but clear about deadlines and deliverables.

How do I discuss confidentiality and security with a blockchain developer?

Talk about signing non-disclosure agreements (NDAs) upfront. Ensure they follow best security practices in their work. Regularly review the security measures that are in place during the project.

What project management tools can help when working with a blockchain developer on Contra?

You can use tools like Trello for task management and Slack for communication. These tools help both you and the developer stay organized. Choose tools that you both find comfortable and effective.

How should I kick-off the project once the blockchain developer is hired?

Start with a welcome meeting to introduce the team and project. Discuss the project plan and deliverables. Set up communication channels and agree on reporting frequencies.

How can I ensure effective communication with the developer?

Establish clear communication guidelines from the start. Use video calls for more complex discussions and text for quick updates. Regularly check in to prevent misunderstandings.

What is the best way to handle scope changes during the project?

Discuss any changes openly and document them. Agree on how these changes will impact the timeline and deliverables. Make sure both parties are okay with how changes are handled.
