FAQs

What should I look for in a Web3.js expert for building a dApp?

What should I include in a project brief when hiring a Web3.js expert?

How do I assess if the Web3.js freelancer understands blockchain security?

Make sure they can talk about important security measures for smart contracts. They should explain how they keep the application safe from issues like hacks. Check if they stay up-to-date on blockchain security best practices.
