        <!-- Step 1 -->
        <div class="step">
          <div class="step-number">1</div>
          <h3>Install Dependencies</h3>
          <p>Install the WDK packages and Observer Protocol SDK:</p>
          <pre><code>npm install @tetherto/wdk @tetherto/wdk-wallet-evm @tetherto/wdk-wallet-btc
npm install @observerprotocol/sdk</code></pre>

          <div class="info-box">
            <p><strong>Note:</strong> The WDK uses native modules for cryptography. Make sure you have Python and build tools installed. On most systems: <code class="inline-code">npm install -g node-gyp</code></p>
          </div>
        </div>

        <!-- Step 2 -->
        <div class="step">
          <div class="step-number">2</div>
          <h3>Generate or Import Seed Phrase</h3>
          <p>The WDK uses BIP-39 seed phrases for deterministic key generation. You can generate a new one or import an existing mnemonic:</p>
          <pre><code>import { AgentWallet } from '@observerprotocol/sdk';

// Generate new seed phrase (save this securely!)
const seedPhrase = AgentWallet.generateSeedPhrase();
console.log('Seed phrase:', seedPhrase);
// → "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"

// Or use existing seed
const wallet = new AgentWallet({
  seedPhrase: process.env.WDK_SEED_PHRASE,
  agentId: 'my-agent-001',
  alias: 'trading-bot-alpha'
});</code></pre>

          <div class="warning-box">
            <p><strong>⚠️ Security:</strong> Store your seed phrase in a secure environment variable. Never commit it to code. The WDK keeps private keys in memory only — no external storage.</p>
          </div>
        </div>

        <!-- Step 3 -->
        <div class="step">
          <div class="step-number">3</div>
          <h3>Initialize Wallets</h3>
          <p>Initialize wallets for the chains you need. Each chain is initialized on-demand:</p>
          <pre><code>// Initialize WDK
await wallet.initializeWDK();

// Initialize Ethereum wallet (for USDT on Ethereum)
const ethWallet = await wallet.initWallet('ethereum', {
  provider: process.env.ETHEREUM_RPC_URL // Optional, defaults to public RPC
});

// Initialize Polygon wallet (for USDT on Polygon - lower fees!)
const polyWallet = await wallet.initWallet('polygon', {
  provider: process.env.POLYGON_RPC_URL
});

// Initialize Bitcoin wallet
const btcWallet = await wallet.initWallet('bitcoin', {
  host: 'bitcoin.lukechilds.co',
  port: 50001,
  protocol: 'tcp'
});

console.log('ETH address:', ethWallet.address);
console.log('BTC address:', btcWallet.address);</code></pre>
        </div>

        <!-- Step 4 -->
        <div class="step">
          <div class="step-number">4</div>
          <h3>Register with Observer Protocol</h3>
          <p>Register your agent to establish identity and enable bilateral verification:</p>
          <pre><code>import crypto from 'crypto';

// Generate a keypair for Observer Protocol identity
// (This is separate from your wallet keys for security isolation)
const identityKey = crypto.generateKeyPairSync('ec', { namedCurve: 'secp256k1' });
const publicKeyHash = crypto
  .createHash('sha256')
  .update(identityKey.publicKey.export({ format: 'der', type: 'spki' }))
  .digest('hex');

// Register agent
await wallet.register({
  alias: 'trading-bot-alpha',
  publicKeyHash: publicKeyHash,
  metadata: {
    description: 'USDT payment agent',
    supportedChains: ['ethereum', 'polygon', 'bitcoin'],
    wdkEnabled: true
  }
});

console.log('✅ Agent registered on Observer Protocol');</code></pre>
        </div>

        <!-- Step 5 -->
        <div class="step">
          <div class="step-number">5</div>
          <h3>Send Verified Payments</h3>
          <p>Send payments with automatic bilateral identity verification. Both sender and recipient must be registered on Observer Protocol:</p>
          <pre><code>// Check if recipient is verified
const recipientCheck = await wallet.checkRecipient('merchant-bot-beta');
console.log('Recipient verified:', recipientCheck.verified);
console.log('Reputation score:', recipientCheck.reputationScore);

// Send USDT on Polygon (fast, cheap)
const payment = await wallet.verifiedSend({
  recipientAlias: 'merchant-bot-beta',
  amount: '10.00',  // 10 USDT
  chain: 'polygon',
  token: 'USDT'
});

console.log('Payment result:', payment);
// {
//   success: true,
//   verification: { alias, publicKeyHash, reputationScore, ... },
//   payment: { txid, status, amount, recipient, chain, ... }
// }</code></pre>

          <div class="info-box">
            <p><strong>Bilateral Verification:</strong> The recipient's identity is verified before payment executes. The payment object includes both the transaction hash and the verification proof.</p>
          </div>
        </div>

        <!-- Step 6 -->
        <div class="step">
          <div class="step-number">6</div>
          <h3>Verify and Submit to ARP</h3>
          <p>Verify the transaction on-chain and submit to the Agent Reporting Protocol for reputation tracking:</p>
          <pre><code>import { WDKVerificationAdapter } from '@observerprotocol/sdk';

const adapter = new WDKVerificationAdapter();

// Verify transaction on-chain
const verification = await adapter.verifyTransaction(
  'polygon',
  payment.payment.txid,
  {
    recipient: '0x...', // Expected recipient
    amount: '10.00',
    token: 'USDT'
  }
);

console.log('Verified:', verification.verified);
console.log('Confirmations:', verification.confirmations);

// Format for ARP
const arpEvent = adapter.formatForARP(verification, {
  amount: '10.00',
  token: 'USDT',
  recipient: '0x...'
});

// Submit to Observer Protocol
await adapter.submitToObserver(agentId, apiKey, arpEvent);
console.log('✅ Transaction attested on Observer Protocol');</code></pre>
        </div>

        <!-- Step 7 -->
        <div class="step">
          <div class="step-number">7</div>
          <h3>Direct Send (No Verification)</h3>
          <p>For payments to non-registered addresses, use direct send:</p>
          <pre><code>// Send to any address (no OP verification)
const result = await wallet.send({
  to: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb',
  amount: '5.00',
  chain: 'ethereum',
  token: 'USDT'
});

console.log('Transaction hash:', result.hash);

// Send Bitcoin
const btcResult = await wallet.send({
  to: 'bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh',
  amount: '0.001',
  chain: 'bitcoin'
});

console.log('BTC txid:', btcResult.txid);</code></pre>
        </div>

        <!-- Step 8 -->
        <div class="step">
          <div class="step-number">8</div>
          <h3>Production Checklist</h3>
          <p>Before deploying to production:</p>
          <ul style="font-size: 13px; color: var(--text-secondary); line-height: 1.8; margin-left: 1.5rem;">
            <li>Use your own RPC endpoints (avoid public nodes for production)</li>
            <li>Get API keys from Etherscan/Polygonscan for verification</li>
            <li>Store seed phrases in secure environment variables or KMS</li>
            <li>Set up monitoring for transaction status</li>
            <li>Implement retry logic for failed transactions</li>
            <li>Consider using Polygon for USDT (much lower fees than Ethereum)</li>
            <li>Test on Sepolia testnet first: <code class="inline-code">USDT_CONTRACTS.sepolia</code></li>
          </ul>
