+# dAppBooster
+
+> This file is mirrored as `CLAUDE.md` for Claude. Keep both files in sync when making changes.
+
+A repository template / starter-kit for building decentralized applications (dApps). Built by BootNode based on 5+ years of dApp development. Docs: https://docs.dappbooster.dev/ Components: https://components.dappbooster.dev/
+
+## Requirements
+
+- Node 24+ (see `.nvmrc`)
+- pnpm 10.30.2+ (enforced via `packageManager` in package.json; corepack will block npm/yarn)
+
+## Setup
+
+1. `pnpm install` (postinstall automatically runs `pnpm wagmi-generate`)
+2. `cp .env.example .env.local`
+3. Edit `.env.local`:
+   - `PUBLIC_APP_NAME` is mandatory
+   - `PUBLIC_WALLETCONNECT_PROJECT_ID` is needed for wallet connection to work
+   - RPC vars (`PUBLIC_RPC_*`) are optional -- wagmi falls back to default public RPCs
+   - Subgraph vars are all-or-nothing: if ANY `PUBLIC_SUBGRAPHS_*` var is missing or empty, codegen will skip and the app will crash at runtime. Either set them all or remove all subgraph-related code.
+4. `pnpm subgraph-codegen` (only if subgraph vars are configured)
+5. `pnpm dev`
+
+## Git Hooks (Husky)
+
+Three hooks run automatically and will block on failure:
+
+- **pre-commit:** lint-staged runs Biome check + Vitest on related files for staged changes
+- **commit-msg:** commitlint enforces conventional commit format. Valid types: `feat`, `fix`, `docs`, `test`, `ci`, `refactor`, `perf`, `chore`, `revert`. PR titles are also validated via CI.
+- **pre-push:** full `tsc --noEmit` type check (pushes with type errors will be rejected)
+
+## Quick Reference
+
+- **Dev server:** `pnpm dev`
+- **Build:** `pnpm build` (runs tsc + vite build)
+- **Lint:** `pnpm lint` (Biome) / `pnpm lint:fix`
+- **Test:** `pnpm test` / `pnpm test:watch` / `pnpm test:coverage`
+- **Generate contract hooks:** `pnpm wagmi-generate`
+- **Generate routes:** `pnpm routes:generate`
+- **Generate subgraph types:** `pnpm subgraph-codegen`
+- **Docs site:** `pnpm docs:dev`
+
+## Tech Stack
+
+- React 19 + TypeScript (strict mode, ESM -- `"type": "module"`, no `require()`)
+- Vite + SWC (fast JSX transform)
+- Wagmi 2 + viem 2 (Ethereum interaction)
+- TanStack Router (file-based routing with auto code-splitting)
+- TanStack Query (server state / data fetching)
+- Chakra UI 3 (component library + theming)
+- ConnectKit (default wallet connector; RainbowKit and Web3Modal also available)
+- LI.FI SDK (token prices/balances)
+- Zod + @t3-oss/env-core (environment variable validation)
+- Biome (linting + formatting)
+- Vitest + Testing Library (testing)
+

+  main.tsx              # Entry point
+  routeTree.gen.ts      # Auto-generated route tree (do not edit)
+```
+
+No top-level barrel exports. Import directly from each file/folder path.
+
+## Provider Stack
+
+The root layout (`src/routes/__root.tsx`) wraps the app in this order:
+
+```
+Chakra Provider (theme, color mode)
+  Web3Provider (WagmiProvider -> QueryClientProvider -> WalletProvider)
+    TransactionNotificationProvider (tx toast context)
+      Header / Outlet (page) / Footer
+```
+
+New providers should be inserted at the appropriate layer based on their dependencies.
+
+## Code Style
+
+- **No semicolons** in TypeScript/JavaScript
+- **Single quotes**
+- 2-space indentation, 100 char line width
+- Import organization handled by Biome
+- Path aliases: `@/src/*` and `@packageJSON`
+- All env vars prefixed with `PUBLIC_` and validated in `src/env.ts`
+- JSDoc comments on exported functions/components (follow existing patterns)
+
+## Styling
+
+- **Chakra UI props** are the primary styling method. No CSS modules, no Tailwind, no styled-components.
+- Theme is defined in `src/components/ui/provider.tsx` using `createSystem` extending `defaultConfig`.
+- Use **semantic tokens** for colors: `bg`, `primary`, `text`, `danger`, `ok`, `warning`. These support light/dark mode. Do not hardcode color values.
+- Fonts: Manrope (body/heading), Roboto Mono (mono/code).
+- Complex components export style objects from a `styles.ts` file, consumed via Chakra's `css` prop or spread into component props.
+
+## Component Conventions
+
+- **Simple components:** single file (e.g., `ExplorerLink.tsx`, `SwitchNetwork.tsx`)
+- **Complex components:** folder with:
+  - `index.tsx` -- main component and public API
+  - `Components.tsx` -- sub-components (styled primitives, layout pieces)
+  - `styles.ts` -- style objects
+  - `useComponentName.ts` -- dedicated hook (optional)
+- Page components go in `src/components/pageComponents/<pagename>/`
+- Shared/reusable components go in `src/components/sharedComponents/`
+
+## Key Patterns
+
+### Adding a New Contract
+
+1. Save ABI in `src/constants/contracts/abis/YourContract.ts` (export as const)
+2. Register in `src/constants/contracts/contracts.ts` with name, ABI, and addresses per chain
+3. Run `pnpm wagmi-generate` to auto-generate typed hooks in `src/hooks/generated.ts`
+
+The contracts array uses `as const satisfies ContractConfig<Abi>[]` for full type inference. Follow this pattern.
+
+Use `getContract(name, chainId)` to retrieve a typed contract config at runtime (e.g., `getContract('WETH', sepolia.id)` returns `{ abi, address }`).
+
+### Generated Hook Naming Convention
+
+`pnpm wagmi-generate` produces hooks in `src/hooks/generated.ts` following this naming pattern:
+
+- `useReadContractNameFunctionName` -- standard read hook
+- `useWriteContractNameFunctionName` -- write hook
+- `useSuspenseReadContractNameFunctionName` -- Suspense-enabled read hook
+- `useSimulateContractNameFunctionName` -- simulation hook
+
+Example: contract named `WETH` with function `allowance` generates `useReadWethAllowance`, `useWriteWethApprove`, `useSuspenseReadWethAllowance`, etc.
+
+### Adding a New Route/Page
+
+1. Create route file in `src/routes/` using `.lazy.tsx` extension for code-split lazy loading (e.g., `yourpage.lazy.tsx`). Use plain `.tsx` only for routes that must be eagerly loaded.
+2. Create page component in `src/components/pageComponents/yourpage/`
+3. Route tree auto-generates via TanStack Router plugin
+
+### Adding a New Network
+
+1. Import chain from `viem/chains` in `src/lib/networks.config.ts`
+2. Add to the appropriate chain array (devChains or prodChains)
+3. Add transport entry with optional custom RPC from env
+4. Add RPC env var to `src/env.ts` if needed
+
+### Environment Variables
+
+- Defined and validated with Zod in `src/env.ts`
+- Access via `import { env } from '@/src/env'` (never `import.meta.env` directly)
+- New variables MUST be added to both `.env.example` and `src/env.ts`
+
+### Web3 Status
+
+- Use `useWeb3Status()` for unified wallet/chain state
+- Use `useWeb3StatusConnected()` when wallet connection is guaranteed (throws otherwise)
+- Use `withWalletStatusVerifier()` HOC to gate components behind wallet connection
+
+### Suspense and Error Boundaries
+
+- Contract read hooks use React Suspense via custom `reactSuspenseRead` wagmi plugin
+- `useTokenLists` is Suspense-based
+- Wrap async components with `withSuspenseAndRetry()` from `src/utils/suspenseWrapper.tsx` -- this is the primary error boundary pattern. It integrates with TanStack Query's `QueryErrorResetBoundary` for automatic retry on query failures.
+- `withSuspenseAndRetry` accepts: `suspenseFallback`, `errorFallback`, `defaultFallbackFormat` ('dialog' | 'default'), `spinnerSize`
+- Simpler variant `withSuspense()` available when retry logic is not needed
+
+### Transaction Handling
+
+Two components for two different jobs -- both auto-wrap with `withWalletStatusVerifier` (do not double-wrap):
+
+- **`TransactionButton`** -- for on-chain transactions. Takes `transaction: () => Promise<Hash>` prop. Attach a `methodId` string property to the function for notification context. Calls `onMined(receipt)` on confirmation.
+- **`SignButton`** -- for message signing only (uses `useSignMessage`). Takes `message`, `onSign`, `onError` props.
+
+`TransactionNotificationProvider` handles toast notifications and tx watching for both.
+
+### Token Management
+
+- Token lists configured in `src/constants/tokenLists.ts`
+- Fetch with `useTokenLists()` hook (Suspense-based). Tokens are deduplicated by `chainId + address` (lowercased). Native tokens are auto-injected for each configured chain.
+- Token prices/balances via `useTokens()` (LI.FI SDK)
+- `TokenInput` + `useTokenInput()` for amount input with validation
+- For raw bigint/decimal conversion in inputs, use `BigNumberInput` (wraps viem's `parseUnits`/`formatUnits`). Never use `parseFloat` or `Number()` for token amounts.
+
+### Wallet Provider
+
+- Default: ConnectKit (configured in `src/lib/wallets/connectkit.config.tsx`)
+- To switch: modify `src/providers/Web3Provider.tsx` imports
+- Alternatives available: RainbowKit (`rainbowkit.config.tsx`), Web3Modal (`web3modal.config.tsx`)
+
+## Auto-Generated Files (Do Not Edit, Do Not Commit)
+
+These files are gitignored and regenerated from source:
+
+- `src/hooks/generated.ts` -- regenerate with `pnpm wagmi-generate`
+- `src/routeTree.gen.ts` -- regenerate with `pnpm routes:generate`
+- `src/subgraphs/gql/` -- regenerate with `pnpm subgraph-codegen`
+
+## Utilities
+
+- **Number formatting:** Use `formatNumber()` from `src/utils/numberFormat.ts` with the appropriate `NumberType` context (`TokenTx`, `FiatTokenPrice`, `SwapPrice`, `PortfolioBalance`, etc.). Never use raw `.toString()` or `.toFixed()` for user-facing numbers.
+- **Explorer links:** `getExplorerLink()` from `src/utils/getExplorerLink.ts`
+- **String truncation:** `truncateStringInTheMiddle()`, `getTruncatedHash()` from `src/utils/strings.ts`
+- **Native token check:** `isNativeToken()` from `src/utils/address.ts`
+- **Hash detection:** `detectHash()` from `src/utils/hash.ts` -- identifies ENS names, transaction hashes, contract addresses, and EOAs
+
+## Testing
+
+- Framework: Vitest with jsdom environment
+- Test files: colocated as `*.test.ts` / `*.test.tsx`
+- Mocking: `vi.mock()` for module mocks
+- Component testing: Testing Library + jest-dom matchers
+- Run: `pnpm test` (single run) or `pnpm test:watch`
