MODULE 12 / 19

Production dApps

Wallet UX, reads/writes, events, IPFS concepts, signed messages, TypeScript front ends, and CI/CD.

Learning outcome

Connect a front end to a testnet contract with safe transaction states.

Study sequence

  1. Concept map: define the system before touching tools.
  2. Evidence lab: collect observable data and record sources.
  3. Hands-on sandbox: use local/testnet resources before real assets.
  4. Security review: identify trust boundaries and failure modes.
  5. Decision memo: state assumptions, invalidation criteria, and what remains unknown.

Required evidence

Every exercise ends with an artifact: transaction hash, contract test, architecture diagram, market worksheet, audit note, or incident runbook. Screenshots alone are not sufficient where machine-readable evidence exists.

Risk rule: Never infer safety from price action, follower counts, artwork, a verified social account, or a green candle. Verify contracts, liquidity, supply/control, permissions, counterparties, and execution conditions separately.
