Frequently Asked Questions (FAQ)
Q: What is the best way to start learning smart contracts?
A: Begin with The Ethereum Compass or Mastering Ethereum, then move to interactive platforms like CryptoZombies or Solidity by Example.
Q: Which framework should I choose: Hardhat or Truffle?
A: Hardhat is recommended for new projects due to better debugging and plugin ecosystem. Truffle remains solid for legacy systems.
Q: How important is security in smart contract development?
A: Critical. A single vulnerability can result in irreversible fund loss. Always use static analyzers like Slither and conduct peer reviews.
Q: Can I develop DApps without knowing Solidity?
A: You’ll need Solidity (or Vyper) for writing backend logic. However, frontend integration can leverage JavaScript libraries like Ethers.js.
Q: Are there any free tools for testing smart contracts?
A: Yes—Hardhat and Ganache offer local testing environments. Plus, platforms like Tenderly allow free simulations.
Q: How do I verify my deployed contract on Etherscan?
A: Use plugins like truffle-plugin-verify or manually submit source code via Etherscan’s verification tab after deployment.
