useWeb3 is a blockchain, crypto and Web3 developer platform.

Why it's awesome?

useWeb3 is not just a job board. It's a one-stop shop for developers to explore, learn, contribute and help them find their blockchain, crypto and Web3 jobs. The job board is highly curated and focuses on projects and companies that work on open-source, protocol, core infrastructure, tooling and fundamentals. Which are generally under-appreciated and funded.

NO trading/speculation/shills/NFTs/tokens, etc.
