Frequently Asked Questions
What programming languages do I need for Ethereum development?
You'll primarily work with Solidity for smart contracts and JavaScript/TypeScript for frontend development. Python and Go are also useful for backend services.
How much does it cost to deploy a DApp?
Costs vary based on contract complexity. Simple contracts might cost $50-$200 in gas fees, while complex systems could exceed $1,000. Testnet deployment is free.
What's the best way to learn Web3 development?
Start with official Ethereum documentation, then build small projects. Join developer communities like Ethereum Stack Exchange for support.
