Initialize TypeScript library for Telegram Web App wallet integration

- Added configuration files: .eslintrc.js, .gitignore, .npmrc, .prettierrc, and multiple tsconfig files for different module systems.
- Created package.json with dependencies and scripts for building, testing, and publishing.
- Implemented core functionality in src/ directory, including wallet management, encryption, and storage handling.
- Added README.md for documentation on installation, usage, and development setup.
- Introduced initial types and constants for better type safety and code organization.

+# @varan-wallet/varan-connect
+
+A lightweight TypeScript library for Telegram Web App wallet integration with support for both CommonJS and ES modules.
+
+## Installation
+
+```bash
+npm install @varan-wallet/varan-connect
+# or
+pnpm add @varan-wallet/varan-connect
+# or
+yarn add @varan-wallet/varan-connect
+```
+
+## Usage
+
+### ES Modules (Recommended)
+
+```typescript
+import { injectVaranWallet } from '@varan-wallet/varan-connect';
+import WebApp from '@twa-dev/sdk';
+
+// Inject the Varan wallet into the window object
+injectVaranWallet(WebApp);
+
+// The wallet is now available at window.injectedWeb3.varan
+const varanWallet = window.injectedWeb3?.varan;
+if (varanWallet) {
+  // Connect to wallet
+  const connection = await varanWallet.connect();
+  
+  // Get accounts
+  const accounts = await connection.accounts.get();
+  
+  // Sign transactions
+  const signer = connection.signer;
+  const signature = await signer.signRaw({
+    address: '0x123...',
+    data: '0x456...'
+  });
+}
+```
+
+### CommonJS
+
+```javascript
+const { injectVaranWallet } = require('@varan-wallet/varan-connect');
+const WebApp = require('@twa-dev/sdk').default;
+
+// Inject the Varan wallet
+injectVaranWallet(WebApp);
+
+// Use the injected wallet
+const varanWallet = window.injectedWeb3?.varan;
+```
+
+## Module Support
+
+This library supports both module systems:
+
+- **ES Modules (ESM)**: Modern JavaScript modules using `import`/`export`
+- **CommonJS (CJS)**: Node.js traditional modules using `require`/`module.exports`
+
+The library automatically detects which module system you're using and provides the appropriate format.
+
+## API
+
+### `injectVaranWallet(webApp: WebApp): void`
+
+Injects the Varan wallet into the window object for Telegram Web App integration.
+
+**Parameters:**
+- `webApp`: The Telegram Web App instance from `@twa-dev/sdk`
+
+**Returns:** `void`
+
+## Types
+
+The library exports comprehensive TypeScript types:
+
+- `WebApp` - Telegram Web App interface from `@twa-dev/sdk`
+- `InjectedWindow` - Extended window interface with injected wallet from `@polkadot/extension-inject`
+- `ConnectRequest`, `SignTransactionRequest` - Request interfaces
+- `ConnectResult`, `SignTransactionResult` - Result interfaces
+- `InjectionConfig` - Configuration options for wallet injection
+
+## Dependencies
+
+**Runtime Dependencies:**
+- `@twa-dev/sdk` - Telegram Web App SDK
+
+**Development Dependencies:**
+- `@polkadot/extension-inject` - Polkadot extension injection types
+- `@polkadot/types` - Polkadot types
+- TypeScript for compilation
+- ESLint for code quality
+- Prettier for code formatting
+- Jest for testing
+
+## Build Outputs
+
+The library provides multiple build outputs:
+
+- `dist/esm/` - ES Modules build (`.mjs` compatible)
+- `dist/cjs/` - CommonJS build (Node.js compatible)
+- `dist/types/` - TypeScript type definitions
+
