Development setup

Set up tools to write and test Solidity.

📖 Key ideas

  1. Remix IDE runs in the browser for quick experiments.
  2. Hardhat and Foundry are professional frameworks.
  3. MetaMask connects to testnets like Sepolia.
  4. Get free testnet ETH from faucets.
  5. Never use mainnet funds for learning.
💡 Real-life example: Testnets are practice pitches: play as much as you like, the runs don't count.
