8/8 — ERC-20 Token Implementation — Check your understanding

PausePause before shipping and confirm you can articulate risks and mitigations without peeking at the code. Auditors and integrators will ask questions like these.

Key points
  • Explain ERC-20s to a:Non-technical friend in two sentences, including what the standard guarantees.
  • Name one concrete risk:When allowances are misused and how you would mitigate it in UX and contracts.
  • Describe one good practice:That reduces mint/burn risk (e.g., using OZ roles, multisig ownership, or timelocks).
  • State why emitting Transfer:And Approval events consistently matters for wallets and indexers.
  • List the steps you:Would take to speed up or cancel a stuck approval transaction.
  • Share one way you:Can prove to integrators that your token code matches the verified source (hint explorer verification).
