FAQs

Think about what you want to build. Is it a blockchain-based app or a smart contract? Write down your project goals and key features. This helps freelancers know if they can help you.
List specific tasks you need done. For example, developing smart contracts, testing them, or integrating them with other systems. Clear deliverables help freelancers understand what you expect.
Very important! Timelines help both you and the freelancer plan better. Talk about when you need your project done. This helps find someone who can work within your schedule.
Past projects show what a freelancer has done before. Look for work similar to your project. This helps you see if they have the right skills and experience for your needs.
Ethereum is the main platform for Solidity. A developer who knows Ethereum well understands how to build and run smart contracts. Make sure they have experience with Ethereum to ensure they can complete your project.
Blockchain projects need to be secure to protect information and money. Ask about security measures and how they test their code. This ensures your project is safe and trustworthy.
Good communication is key to a successful project. Decide on tools like chat apps or emails for regular updates. Clear communication helps keep the project on track.
Break down the project into smaller parts, like coding or testing. Agree on what should be done by when. Milestones help track progress and keep everyone focused on the goal.
Knowing their workflow helps you see how they work. Some freelancers might provide daily updates, others weekly. Understanding this helps set the right expectations for communication and delivery.
