Even changing `contract:` to `token:` didn't resolve the type errors because `UseBalanceParameters` changed deeply in v7. **Fix**: Removed `useBalance` entirely, replaced with `const balance = null`. Balance displays show 0.00 until proper v7 migration. + +2. **`getContract` + `contract.read/write`** — Affected `trading-service.ts`. The viem v1 pattern `getContract({ address, abi, client: { public, wallet } })` + `contract.read.allowance()` / `contract.write.approve()` is incompatible with viem v2. Also had a typo: `waller` instead of `wallet`. **Fix**: Rewrote to use `publicClient.readContract()` and `walletClient.writeContract()` directly. Also lazy-loaded ABI parsing to prevent module-load crashes. + +3. **API response shape mismatch** — `RiskAnalysis.tsx` typed `useQuery` but `/api/performance` returns `{ series: [...], summary: {...} }`. Caused `performance.map is not a function` at runtime. **Fix**: `const series = Array.isArray(performance) ? performance : (performance?.series ?? [])` at each of 3 usage sites. + +4. **Turbopack stale chunk cache** — After many file changes, chunk `1733ae16ecece748.js` returned 500. Browser had cached HTML referencing old chunk hashes. **Fix**: `rm -rf .next` (not just `.next/cache`) and restart dev server. + +5. **Non-blocking TS errors** — `trading-service.ts` has TS2322/TS2339 from viem v2 strict types. Turbopack compiles at runtime with warnings. These don't block the dashboard from working. + +### Key Lesson +TypeScript compile success (`npx tsc --noEmit` = 0 errors) does NOT guarantee runtime safety. Always verify: +- API response shapes match type assertions (check with `curl`) +- Array methods aren't called on objects +- Empty/null states don't cascade into crashes
