BlockIQ

Advanced Stacks blockchain analytics platform powered by AI agents and the ADK-TS framework. BlockIQ transforms complex blockchain data into natural conversations and interactive visualizations, making the Bitcoin economy accessible to everyone.

BlockIQ currently operates on the Stacks Blockchain Testnet for demonstration and development purposes. The MCP server connects to the Stacks Testnet API (api.testnet.hiro.so) to fetch wallet data, transactions, and blockchain information. This allows for safe testing and experimentation without affecting mainnet assets. The architecture is designed to seamlessly switch to mainnet by simply updating the API endpoint configuration when ready for production deployment.

BlockIQ is an intelligent blockchain analytics platform that allows users to analyze Blockchain wallet data through natural language conversations. Instead of struggling with raw blockchain explorers or writing complex queries, users can simply ask questions and receive intelligent, contextual answers with beautiful visualizations.

The platform leverages the ADK-TS (Agent Development Kit for TypeScript) framework to orchestrate multiple AI agents, each specialized for different types of blockchain analysis. Combined with a custom Model Context Protocol (MCP) server, BlockIQ provides unprecedented access to blockchain data through conversational AI.

BlockIQ is built on the ADK-TS framework, which provides the foundation for our multi-agent AI system. The framework enables:

• Agent orchestration and lifecycle management
• Seamless integration with multiple AI providers (OpenAI, Google, Anthropic, Groq, Hugging Face)
• Built-in MCP (Model Context Protocol) support for tool calling
• Automatic error handling and retry mechanisms
• Conversation state management

The ADK integration is implemented in src/lib/adk-framework-integration.ts, which creates a specialized BlockIQ agent with:

• Custom instructions for blockchain analysis
• MCP tool integration for data fetching
• Provider-agnostic model configuration
• Smart caching and health monitoring

BlockIQ supports multiple AI providers through ADK-TS:

• OpenAI: GPT-4, GPT-4 Turbo, GPT-3.5 Turbo
• Google: Gemini Pro, Gemini 1.5 Pro
• Anthropic: Claude 3 Opus, Claude 3 Sonnet, Claude 3 Haiku
• Groq: Llama 3, Mixtral models
• Hugging Face: Various open-source models

Users can configure their preferred provider and model through the settings interface. The system includes automatic model name normalization to handle provider-specific naming conventions.

BlockIQ implements a custom MCP server (src/mcp/blockiq-mcp-server.js) that exposes specialized blockchain analysis tools to the AI agent. This server follows the official MCP specification and provides:

1. getWalletData

   • Fetches comprehensive Stacks wallet information
   • Returns balance, recent transactions, and metadata
   • Used for initial wallet overview and basic queries

2. getTransactions

   • Retrieves transaction history with pagination
   • Supports offset-based navigation for specific transactions
   • Enables precise transaction lookup by number or range

3. executeSpiderAnalysis

   • Core tool for comprehensive blockchain analysis
   • Fetches ALL transactions for a wallet address
   • Executes custom JavaScript code on aggregated data
   • Implements smart caching to avoid redundant API calls
   • Supports both data prefetching and code execution modes

4. debugAndFixCode

   • Automatically debugs and fixes JavaScript code errors
   • Applies common fixes (syntax errors, missing imports, etc.)
   • Re-executes fixed code on cached transaction data
   • Enables self-correcting AI analysis

5. preloadTransactionData

   • Background data preloading for faster analysis
   • Caches complete transaction datasets
   • Reduces latency for subsequent executeSpiderAnalysis calls

BlockIQ implements an intelligent caching system that dramatically improves performance:

The cache file stores complete transaction datasets with metadata:

{
  "_metadata": {
    "address": "ST2QKZ4FKHAH1NQKYKYAYZPY440FEPK7GZ1R5HBP2",
    "totalTransactions": 16413,
    "fetchedAt": "2025-01-21T18:53:16.123Z",
    "batches": 329
  },
  "data": [
    {
      "limit": 50,
      "offset": 0,
      "total": 16413,
      "results": [
        {
          "tx_id": "0x847bedd...",
          "tx_type": "token_transfer",
          "sender_address": "ST2QKZ...",
          "token_transfer": {
            "recipient_address": "ST38RMD...",
            "amount": "500000000",
            "memo": "0x666175636574"
          },
          "fee_rate": "180",
          "block_height": 4,
          "burn_block_time": 1735930199,
          "tx_status": "success"
        }
        ...
      ]
    }
  ]
}

BlockIQ implements a sophisticated caching strategy that optimizes performance while ensuring data freshness:

1. Address Comparison

   • When a wallet is analyzed, the system first checks if cache exists
   • Compares the requested address with the cached address
   • If addresses differ, old cache is cleared and fresh data is fetched

2. Transaction Count Verification

   • System fetches ONLY the current transaction count from the API
   • Compares current count with cached transaction count
   • This lightweight check (single API call) determines if new transactions occurred

3. Smart Update Strategy

   • If counts match: Cache is valid, no fetching needed (instant response)
   • If counts differ: Only fetch the NEW transactions, not the entire history

When new transactions are detected, BlockIQ uses an intelligent incremental update:

Example Scenario:

• Cached transactions: 16,000
• Current transactions: 16,010
• Difference: 16,010 - 16,000 = 10 new transactions

Instead of re-fetching all 16,010 transactions, the system:

1. Fetches only the latest 10 transactions using limit=10&offset=0
2. Prepends these new transactions to the existing cache
3. Updates the metadata with new count and timestamp
4. Preserves all historical data without redundant API calls

This approach provides:

• 99.9% reduction in API calls for returning users
• Instant analysis for unchanged wallets
• Minimal bandwidth usage for incremental updates
• Always up-to-date data without full re-fetches

• Initial Analysis: Full fetch and cache creation
• Subsequent Analysis (same address, no new txs): Instant cache reuse
• Subsequent Analysis (same address, new txs): Incremental update only
• Different Address: Cache cleared, new full fetch
• Background Preloading: Automatic cache warming during user interaction

• Wallets with 100,000+ transactions: Analysis completes in under 2 seconds (vs 5+ minutes without cache)
• Returning users: Instant results (0 API calls if no new transactions)
• New transactions: Only fetch what's needed (10 new txs vs 100,000 total)
• API rate limit friendly: Minimal requests, maximum efficiency

The executeSpiderAnalysis MCP tool is BlockIQ's most powerful feature, enabling comprehensive analysis of entire transaction histories through custom JavaScript code execution.

1. Data Aggregation

   • Fetches ALL transactions for a wallet (can be thousands)
   • Retrieves data in batches of 50 transactions
   • Implements rate limiting to avoid API throttling
   • Saves aggregated data to cache.tmp.json

2. Code Execution

   • AI generates custom JavaScript code for analysis
   • Code reads from cache.tmp.json file
   • Processes all transactions using standard JavaScript
   • Returns results as JSON output

3. Error Recovery

   • If code fails, error details are sent back to AI
   • AI analyzes error and generates fixed code
   • System re-executes fixed code automatically
   • Process repeats up to 10 times until success

const fs = require("fs");
const fileData = JSON.parse(fs.readFileSync("cache.tmp.json", "utf8"));
const data = fileData.data || fileData;
const allTransactions = data.flatMap((batch) => batch.results || []);

// Analysis logic here
const result = {
  // Analysis results
};

console.log(JSON.stringify(result));

Finding the first transaction:

const sortedTxs = allTransactions.sort(
  (a, b) => a.burn_block_time - b.burn_block_time
);
const firstTx = sortedTxs[0];
console.log(
  JSON.stringify({
    transactionId: firstTx.tx_id,
    receiver: firstTx.token_transfer?.recipient_address,
    amount: firstTx.token_transfer?.amount,
    timestamp: new Date(firstTx.burn_block_time * 1000).toISOString(),
  })
);

Top recipients analysis:

const recipients = {};
allTransactions.forEach((tx) => {
  if (tx.token_transfer?.recipient_address) {
    const addr = tx.token_transfer.recipient_address;
    recipients[addr] = (recipients[addr] || 0) + 1;
  }
});
const topRecipients = Object.entries(recipients)
  .sort(([, a], [, b]) => b - a)
  .slice(0, 10);
console.log(JSON.stringify({ topRecipients }));

BlockIQ introduces a revolutionary Graph Protocol system that enables AI to automatically generate interactive visualizations from natural language requests.

The Graph Protocol is a JSON-based specification that contains everything needed to render professional charts:

{
  "graph": "VBC",
  "x_axis_data": ["Jan", "Feb", "Mar"],
  "y_axis_data": [1500000000, 2000000000, 1800000000],
  "y_axis_scale": ["0", "500M", "1000M", "1500M", "2000M"],
  "title": "Monthly STX Transfer Activity",
  "subtitle": "STX transferred each month",
  "value_label": "STX",
  "colors": ["#3b82f6", "#8b5cf6", "#ec4899"],
  "text": "Peak activity occurred in February with 2B STX transferred...",
  "tooltip_data": {
    "Jan": {
      "value": 1500000000,
      "info": "Winter activity period - 1.5B STX",
      "additionalMetrics": {
        "success_rate": "98.7%",
        "avg_per_tx": "15M STX"
      }
    }
  }
}

• VBC (Vertical Bar Chart): Time series, monthly data, transaction counts
• HBC (Horizontal Bar Chart): Rankings, top lists, comparisons
• PG (Pie Chart): Proportions, percentages, distributions
• MPG (Modern Pie Chart): Advanced pie chart with line connectors and external labels
• LC (Line Chart): Trends over time, balance changes
• AC (Area Chart): Cumulative data, volume over time
• DG (Donut Chart): Proportions with center totals

1. User Request: "Show me monthly transaction activity with a chart"
2. AI Analysis: Determines VBC is appropriate for time-series data
3. Data Collection: Uses executeSpiderAnalysis to fetch all transactions
4. Data Processing: Aggregates transactions by month using JavaScript
5. STX Conversion: Converts micro STX to regular STX (divides by 1,000,000)
6. Protocol Generation: Creates complete Graph Protocol JSON
7. Response: Returns ONLY the JSON (no extra text)
8. Frontend Rendering: GraphRenderer component creates interactive visualization

Blockchain data stores STX amounts in micro STX (1 STX = 1,000,000 micro STX). For graphs, the AI ALWAYS converts to regular STX:

const microStxAmount = parseInt(tx.token_transfer.amount);
const stxAmount = microStxAmount / 1000000; // Convert to STX

This prevents huge unreadable numbers in charts and creates proper Y-axis scales like ["0", "500M", "1000M", "1500M"] instead of raw values.

• Smart Tooltips: Context-aware labels showing value, percentage, and additional metrics
• Hover Effects: Elements brighten and scale on mouse interaction
• Click-to-Expand: Graphs can be clicked to open in full-screen view
• Smooth Animations: Staggered entry animations for visual appeal
