Plain-English storyGas is the “meter” that measures computer work on-chain. Fees are what you pay to get that work done. You’ll learn why fees change, what “base fee + tip” means, and how to pick a fee that balances speed and cost instead of guessing.
What you’ll learnHow gas units relate to actions (simple send vs swap), how busy networks push fees up, and how wallet presets (slow/normal/fast) map to real-world timing. You’ll also see why zero-fee prompts are a red flag.
Your goalLeave with a personal fee checklist: what “normal” looks like on your chain, when to wait, when to speed up, and how to spot scammy fee prompts.
You can do all of this with MetaMask, or with other wallets like Rabby or Coinbase Wallet. The screens look different, but the fees work the same way.
