Trump Alpha — Frontend (trumpsignal.com)

Next.js 16 dashboard for the Trump Alpha backend. Real-time signals, Hyperliquid position management UI, KOL talks-vs-trades view, Macro Vibes regime panel. Read-only for the public; wallet-bound features (Pro) for auto-trade subscribers.

This is the AI-readable entry doc. Read this first on entering the repo.

What this repo is

• Pure frontend — Next.js 16 App Router, TypeScript, server components + client components, deployed to Vercel.
• Talks to a Python backend at https://api.trumpsignal.com (or localhost:8000 in dev). All trading state, signals, AI scoring, Hyperliquid integration lives in the sibling /Users/k/Public/Claude/ backend repo. See its CLAUDE.md.
• No server-side trading logic lives here. Frontend is a thin layer over the API + WebSocket — even "open a position" routes to a backend endpoint that does the signed-request verification + HL call.

---

Stack quirks (Next.js 16 specific)

• proxy.ts replaces middleware.ts in Next.js 16. Routes that need CORS / locale rewriting go through proxy.ts at the root.
• params is async (Promise<{...}>) in all dynamic routes. ALL page components await it:

  export default async function Page({ params }: { params: Promise<{ locale: string }> }) {
    const { locale } = await params
    ...
  }
  

  Forgetting the await redirects to /undefined/... silently. Several pages were broken this way pre-v2.0 — be alert if you copy older patterns.
• i18n is shelved. The [locale] segment exists, messages/zh.json exists, but Chinese branches are kept as dead code with a comment // i18n shelved — see messages/zh.json. Don't activate without an ADR. Currently isZh = false is hardcoded in metadata generators.
• runtime = 'edge' on a few routes (app/icon.tsx, OG image generator). Edge runtime has no fs / no Node APIs — don't import server-side libs there.

API layer

All API calls go through lib/api.ts. Single fetchJson<T> wrapper:

• Reads base URL from env (NEXT_PUBLIC_API_URL) or proxies through /api/proxy/[...path]/ for same-origin CORS-free calls.
• Wallet-scoped reads (/user/.../public, /positions/open) pass wallet as query param + signed ts/sig.
• Mutations (subscribe, manual_close, set_auto_trade, manual-window) build an EIP-191 signed payload via wagmi → POST signed envelope.

Auth model: no sessions, no cookies. Wallet address + signed timestamp

• signature on every mutating call. Verification lives in the backend (signed_request.verify_signed_request). The same wallet that signed the HL API key envelope at subscribe time is the only one that can later mutate the subscription.

---

State management

• No global store (no Redux/Zustand). Tree-local state + props.
• SWR-style cache in lib/cache.ts for the API-heavy pages.
• WebSocket singleton via WsProvider — used by SignalMonitor and live price tickers.
• localStorage holds wallet address only (for re-connect UX). HL API keys NEVER touch the client — they're submitted once at subscribe, sent encrypted, and decrypted only inside the backend.

---

Design system

Tokens in app/[locale]/globals.css:

• Colors — oklch() color space throughout. Brand orange = #f5a524, brand dark = #0a0907. var(--up) green / var(--down) red / var(--ink-1..3) text tiers.
• Dark mode via [data-theme="dark"] attribute on <html>. Most components use oklch(L% c h) so dark/light switching is automatic.
• Macro Vibes specific — extensive .macro-* classes for the 8-indicator layout. Threshold chips have :not(.active) { opacity: 0.45 } and .active is tone-filled (green/red/amber).

---

Things that LOOK like bugs but aren't

• Old code references "/en/btc" — Macro Vibes was renamed from "BTC Signal" in v2.0. All routes are now /en/macro. app/[locale]/btc/page.tsx EXISTS intentionally as a permanent redirect to /en/macro — that's fine. If you find a stale /en/btc hardcoded link anywhere else, it's a real bug — fix it.
• isZh = false in metadata generators — i18n was shelved pre-launch. See "Stack quirks" above.
• Multiple proxy.ts patterns — Next.js 16 split middleware behaviour. Keep proxy logic in the single proxy.ts at root.
• 'use client' directives on many pages — necessary for client-side WS / wallet interactions. Don't try to convert without verifying the WS
  • wagmi imports work in server components.
• telegram.send_message accepting int | str for chat_id — the backend uses string form for the public channel ("@trumpalpha") and integer for private user chats. Both are valid; no frontend change needed.
• x-forwarded-for is deleted in the proxy — KNOWN BUG (see below). Don't "fix" it by just removing the delete; the correct fix is to relay the real client IP. See Open Known Issues.

---

Open known issues (frontend)

• Rate limit bypass via proxy (FIXED 2026-05-29): route.ts no longer deletes x-forwarded-for. It now reads the real client IP from the incoming x-forwarded-for or x-real-ip header (set by Vercel/CDN) and sets it on the upstream request so slowapi can distinguish individual clients.

• signMessageAsync in OpenPositions polling deps (MEDIUM, FIXED 2026-05-29): Removed signMessageAsync and isZh from the useEffect dependency array in components/positions/OpenPositions.tsx. Neither is used inside the effect; including them caused wagmi reference churn to restart the 15s poll timer.

• Stale types after BUG-08/BUG-14 (FE-01–06, FIXED 2026-05-29):

  • types/index.ts: price_impact.asset widened from 'BTC' | 'ETH' to string (BUG-14 now tracks the actually-traded asset which may be SOL/TRUMP/etc.).
  • lib/useRealtimeData.ts: PriceMsg.asset and Handlers.onPrice widened to string (BUG-08 expanded the WS price stream to all ASSET_MAP entries).
  • store/dashboard.ts: livePrices changed from { BTC; ETH } to Record<string, number | null>; setLivePrice param widened to string.
  • lib/api.ts: getPrices asset param widened to string.
  • components/trades/TradeTable.tsx: hardcoded ASSETS = ['all','BTC','ETH','SOL'] replaced by a dynamic useMemo that builds the asset list from the actual trade set — new perps (TRUMP, BNB, etc.) appear in the filter automatically.
  • DashboardClient.tsx + TradesPageClient.tsx: removed isZh from useEffect deps (compile-time constant; including it restarted effects on every render).

• Interaction/button bugs sweep (UI-A..G, FIXED 2026-05-29):

  • A OpenPositions.tsx close-modal backdrop now dismisses in 'err' state too (previously stuck — only 'idle' dismissed). State is reset on dismiss so the next open is clean.
  • B confirmCloseTrade distinguishes user-cancelled signature (isUserRejection) from real failure: cancellation closes the modal silently; real errors stay open in 'err' state with the message.
  • C SystemControl.flipAuto claims busy=true before await confirmSign(...). Rapid double-click on the ON/OFF pill no longer slips past the guard. The slot is released if the user cancels the sheet.
  • D BotConfigPanel "Rotate" API-key button resets keyState/keyErr so a previously-failed save's red error doesn't bleed into the new edit.
  • E Paper/Live Switch clears subErr when toggled so a stale subscribe-error doesn't sit next to the new choice.
  • F confirmSign keeps a module-scope _activeCancel; a second call while a sheet is mounted resolves the first promise with false instead of leaving its caller hanging forever. All 9 call sites verified to cleanly handle the false return (setBusy(false) / setLoadState('idle')).
  • G OpenPositions.toggleGrow errors now write to a dedicated growErr state with a 4-second auto-clear, instead of squatting in the panel-header err banner shared with the 15-s poll error.

How to verify changes locally

# Type check (must pass with 0 errors)
npx tsc --noEmit

# Production build (catches missing pages, stale imports)
rm -rf .next && npx next build

# Dev server — NOTE: this app runs on port 3001 (see package.json:
# `next dev -p 3001` / `next start -p 3001`), NOT the Next.js default 3000.
# Any external doc, script, or healthcheck must target 3001.
npm run dev

# Pages-200 sweep (every locale page returns 200) — port 3001

SEO / GEO surface (don't break)

• app/layout.tsx has JSON-LD schema.org markup (Organization, SoftwareApplication, FAQ). Search engines + AI crawlers read this.
• public/llms.txt — canonical doc for AI crawlers (Perplexity, ChatGPT browse, Google AI Overviews). Edit BOTH this file AND layout.tsx when renaming product features.
• app/sitemap.ts — sitemap.xml. Add new routes here.
• OG image — app/opengraph-image.tsx dynamically renders the social card. Keep the brand pill list in sync with current features.

---

Coupling to backend

• API contract lives in TypeScript types under lib/api.ts (e.g. OpenPositionsResponse, TodayStats, BotTrade). These must match the backend Pydantic models in app/api/*/positions.py etc.
• When backend adds a field (e.g. BotTrade.released_at), this repo's lib/api.ts types may need updating to surface it in the UI. Currently released trades are FILTERED OUT by the backend's /positions/open — they don't appear here, so no UI for "managed vs released" yet.
• When backend renames a route (e.g. /btc/page.tsx → /macro/page.tsx), search for ALL references (including telegram deep-link map in backend/app/services/telegram.py).

---

Deploy

Vercel auto-deploys main branch pushes. No special build flags. Env vars in Vercel dashboard:

• NEXT_PUBLIC_API_URL — backend HTTPS origin
• NEXT_PUBLIC_SITE_URL — canonical site URL (used for OG, sitemap)
• NEXT_PUBLIC_WS_URL — WebSocket endpoint (usually wss://api...)
