FAQ
Questions about hiring Web3 developers
Is Web3 the same as blockchain development?
It overlaps. Web3 usually refers to user-facing apps built on blockchain; contract work is a related specialism.
Can users sign in with a wallet?
Yes, with standards such as Sign-In with Ethereum.
Do they also write contracts?
Some do. Check contract work separately, since security needs are different.
