### Copy public assets

Copy the `public/` folder from the [seismic-starter](https://github.com/SeismicSystems/seismic-starter) repo into `packages/web/public/`. This includes the clown sprites, button images, background, logo, and audio files used by the game UI.

### Configure Vite

Update `vite.config.ts` to add a path alias for cleaner imports:
Update `vite.config.ts`:

```typescript
import { resolve } from "path";
import { defineConfig } from "vite";

import tailwindcss from "@tailwindcss/vite";
import react from "@vitejs/plugin-react-swc";
import path from "path";
import { defineConfig } from "vite";

// https://vite.dev/config/
export default defineConfig({
plugins: [react(), tailwindcss()],
envDir: resolve(__dirname, "../.."),
resolve: {
alias: {
"@": path.resolve(__dirname, "./src"),
"@": resolve(__dirname, "src"),
},
},
});
```

The `envDir` points to the monorepo root so that `.env` files at the top level are available to the web package.

### Environment variables

Create a `.env` file in `packages/web`:
Create a `.env` file at the monorepo root:

1. **WagmiProvider** — manages wallet connections and chain state via wagmi hooks (`useAccount`, `useConnect`, etc.)
2. **QueryClientProvider** — provides React Query for caching and background data fetching
3. **RainbowKitProvider** — adds a polished wallet connect modal UI
4. **ShieldedWalletProvider** — the Seismic-specific layer from `seismic-react` that derives a shielded wallet client from the connected wagmi account, enabling shielded reads and writes
4. **ShieldedWalletProvider** — the Seismic-specific layer from `seismic-react` that derives a shielded wallet client from the connected wagmi account, enabling shielded reads and writes. It takes `config` and `options` — the options include `publicTransport`, `publicChain`, and an `onAddressChange` callback.

The `onAddressChange` handler auto-funds new wallets when running on `sanvil` (local dev), so you don't need to manually send ETH to test accounts.

### Entry point: main.tsx

This is the same pattern you'd use for any Seismic dApp. The `ShieldedWalletProvider` is the only Seismic-specific addition to a standard wagmi + RainbowKit setup.
Create `src/main.tsx` to bootstrap the app with theme and state management:

```typescript
import { StrictMode } from 'react'
import { createRoot } from 'react-dom/client'
import { Provider } from 'react-redux'
import { ToastContainer } from 'react-toastify'
import 'react-toastify/dist/ReactToastify.css'

import App from '@/App.tsx'
import { store } from '@/store/store'
import theme from '@/theme.ts'
import { ThemeProvider } from '@mui/material/styles'

import './index.css'

createRoot(document.getElementById('root')!).render(
<StrictMode>
<ThemeProvider theme={theme}>
<Provider store={store}>
<App />
<ToastContainer />
</Provider>
</ThemeProvider>
</StrictMode>
)
```
