2/8 — ERC-20 Token Implementation — Lesson overview

BuildImplement a production-ready ERC-20 by assembling the right OpenZeppelin pieces and avoiding footguns. Wire a token with name, symbol, decimals, mint/burn flows, and allowances; add access control; and understand how approvals can be misused.

GuardKeep the code boring where it should be (stick to the spec) and add safeguards where it matters (role-gated minting, revocable allowances, thorough events). See how explorers present your token, why verification matters, and how to test supply changes without relying on “it worked on my machine.”

ShipIf you already know how to deploy “a token,” use this to raise your standards: tighter tests, clearer docs for integrators, explicit supply policy. If you’re new, consider this your onboarding to the most reused standard in crypto. By the end, you should have a starter kit you’d ship publicly and show an auditor.
