## Installation

```bash
npm install @tether/multi-chain-wallet-sdk
```

## Quick Start

```typescript
import { WalletSDK } from '@tether/multi-chain-wallet-sdk';

// Initialize SDK
const sdk = new WalletSDK({
  aiEnabled: true,
  networks: ['ethereum', 'polygon', 'bitcoin'],
  apiKeys: {
    ethereum: 'your-infura-key',
    polygon: 'your-polygon-key'
  }
});

// Create a new wallet
const { mnemonic, accounts } = await sdk.createWallet();
console.log('Wallet created:', mnemonic);
console.log('Accounts:', accounts);

// Get balances across all chains
const ethAccount = accounts.find(acc => acc.chain === 'ethereum');
const balances = await sdk.getAllBalances(ethAccount.address);
console.log('Balances:', balances);

// AI-powered transaction analysis
const transaction = {
  from: ethAccount.address,
  to: '0x742d35Cc6634C0532925a3b8D8b3f8B2C3F5C8D1',
  value: '1.5',
  chain: 'ethereum'
};

const analysis = await sdk.analyzeTransaction(transaction);
console.log('AI Analysis:', analysis);

// Send transaction
if (analysis.risk === 'low') {
  const txHash = await sdk.sendTransaction(transaction);
  console.log('Transaction sent:', txHash);
}
```
