⚡ Nani - Real-Time Blockchain Event Monitoring and Notifications

The first open-source, plugin-based notification platform for Polkadot. Built for the Polkadot Cloud 2025.

TypeScript Node.js Polkadot Polkadot.js API License: MIT

🚀 Try Live Demo | 📚 API Docs | 🐙 GitHub

🎯 The Problem

Web3 developers face an impossible choice when building notification systems:

Option Reality Cost
Enterprise SaaS (Notifi, $12.5M raised) ❌ Vendor lock-in, $10K+ contracts, closed source $10,000+/year
Free Tools (Web3Alert, Hal Notify) ❌ No API access, SaaS-only, can't customize Limited features
Build Your Own ❌ 1-3 months development, $10K-$30K cost $20,000+
Ignore Notifications ❌ Broken UX, poor engagement Lost users

You cannot have enterprise features + free access + full ownership... UNTIL NOW.

✨ The Solution: Nani

Nani disrupts the ecosystem by being the first truly open-source, plugin-based notification platform, making infrastructure free, secure, and infinitely extensible.

🚀 What Makes Nani Different

// Add Telegram notifications in 20 lines - NO RECOMPILATION NEEDED
// src/plugins/notifications/telegram.ts
import { NotificationPlugin } from '../../types/pluginTypes';

const telegram: NotificationPlugin = {
  name: 'telegram',
  
  init() {
    if (!process.env.TELEGRAM_BOT_TOKEN) {
      throw new Error('TELEGRAM_BOT_TOKEN required');
    }
  },
  
  async execute(message: string, config: any) {
    const url = `https://api.telegram.org/bot${process.env.TELEGRAM_BOT_TOKEN}/sendMessage`;
    await fetch(url, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({
        chat_id: config.chatId,
        text: message,
        parse_mode: 'Markdown'
      })
    });
  },
  
  validateConfig(config: any): boolean {
    return !!config.chatId;
  }
};

export default telegram;

Drop file → Restart → Telegram works. Zero build required.

Key Architecture Decisions

1. Adapter Pattern for Chain Abstraction

  • ChainAdapter interface enables multi-chain support
  • Substrate adapter wraps Polkadot.js API
  • Future: Add EVM, Cosmos, Solana adapters

2. Worker Pool for Plugin Isolation

  • Uses workerpool for true thread parallelism
  • Each event processed in isolated worker
  • Prevents one plugin crash from affecting others
  • Scales to CPU cores automatically

3. Hybrid Storage Strategy

  • AceBase: Fast indexed queries for logs/stats
  • Encrypted JSON: Secure tenant configs
  • Filesystem: Simple, no external DB required

4. Event Serialization Pipeline

  • Polkadot.js types → Plain JSON before worker dispatch
  • Solves structured clone limitation
  • Workers receive clean, serializable data

5. Single-Process vs Cluster Mode

  • PaaS (Railway, Render): Single process (auto-scaled by platform)
  • VPS/Dedicated: Cluster mode (1 worker per CPU)
  • Auto-detects environment and optimizes

🚀 Quick Start (5 Minutes)

Prerequisites

1. Clone & Install

git clone https://github.com/cenwadike/nani
cd nani
npm install

2. Configure Environment

cp .env.example .env
nano .env

Minimum required:

# Generate with: openssl rand -base64 32
JWT_SECRET=your-super-secret-jwt-key-minimum-32-characters
ENCRYPTION_KEY=32-character-aes-key-1234567890abcdef

# Port (default: 3000)
PORT=3000

# Data directory (auto-created)
DATA_ROOT=./data

Optional notification services:

# Twilio SMS
TWILIO_SID=ACxxxxxxxxxxxxxxxxxxxxx
TWILIO_TOKEN=your_auth_token
TWILIO_FROM=+15551234567

# SMTP Email
SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_SECURE=false
SMTP_USER=you@gmail.com
SMTP_PASS=your-app-password
SMTP_FROM="Nani Alerts <you@gmail.com>"

3. Configure Chains

Edit chains.json to customize RPC endpoints:

{
  "chains": [
    {
      "name": "westend",
      "adapterType": "substrate",
      "endpoints": [
        "wss://westend-rpc.polkadot.io",
        "wss://westend-rpc.dwellir.com"
      ],
      "tokenSymbol": "WND"
    },
    {
      "name": "asset-hub-westend",
      "adapterType": "substrate",
      "endpoints": [
        "wss://westend-asset-hub-rpc.polkadot.io"
      ],
      "tokenSymbol": "WND"
    }
  ]
}

4. Run

# Development (with hot reload)
npm run dev

# Production
npm run build
npm start

# Docker (easiest)
docker-compose up -d

5. Verify

curl http://localhost:3000/health | jq .

Expected response:

{
  "status": "healthy",
  "timestamp": "2025-11-16T20:00:00.000Z",
  "uptime": 3600,
  "chains": {
    "westend": "connected",
    "asset-hub-westend": "connected"
  },
  "adapters": {
    "total": 2,
    "healthy": 2
  }
}

6. Test the API

Get authentication token:

curl -X POST http://localhost:3000/auth \
  -H "Content-Type: application/json" \
  -d '{"email": "your@email.com"}'

Response:

{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "tenantId": "b3ed617e005ce4db",
  "message": "Authentication successful"
}

Setup monitoring:

curl -X POST http://localhost:3000/setup \
  -H "Authorization: Bearer <your-token>" \
  -H "Content-Type: application/json" \
  -d '{
    "chains": [{
      "chainId": "asset-hub-westend",
      "address": "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY",
      "plugins": {
        "activities": ["transfers"],
        "notifications": [{
          "type": "discord",
          "config": {
            "webhook": "https://discord.com/api/webhooks/YOUR_WEBHOOK"
          }
        }]
      }
    }]
  }'

Trigger a test: Send WND to your address via Westend Faucet

Result: Discord notification arrives in <100ms! 🎉

🔌 Plugin System

Why Plugins Matter

Competitors: You get what they built. Period.
Nani: Drop a 20-line TypeScript file, restart, add any feature instantly.

Plugin Types

// 1. Activity Plugins - Filter blockchain events
export interface ActivityPlugin {
  name: string;
  filter(event: any, address: string, chainId: string): boolean;
  log(event: any, address: string, chainId: string, tokenSymbol: string): any;
  formatMessage(log: any, tokenSymbol: string): string;
}

// 2. Notification Plugins - Send alerts
export interface NotificationPlugin {
  name: string;
  init(): void;
  execute(message: string, config: any): Promise<void>;
  validateConfig(config: any): boolean;
}

// 3. Stats Plugins - Compute analytics
export interface StatsPlugin {
  name: string;
  compute(logs: any[], filters?: any): any;
}

Example: Custom Slack Plugin

// src/plugins/notifications/slack.ts
import { NotificationPlugin } from '../../types/pluginTypes';

const slack: NotificationPlugin = {
  name: 'slack',
  
  init() {
    if (!process.env.SLACK_BOT_TOKEN) {
      throw new Error('SLACK_BOT_TOKEN required');
    }
  },
  
  async execute(message: string, config: any) {
    await fetch('https://slack.com/api/chat.postMessage', {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.SLACK_BOT_TOKEN}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        channel: config.channel,
        text: message
      })
    });
  },
  
  validateConfig(config: any): boolean {
    return !!config.channel;
  }
};

export default slack;

Usage: Add SLACK_BOT_TOKEN to .env → Restart → Works immediately.

💡 Use Cases

1. Portfolio Tracker

// Track all transfers + staking rewards
const setup = {
  chainId: "polkadot",
  address: "1FRMM8PEiWXYax7rpS6X4XZX1aAAxSWx1CrKTyrVYhV24fg",
  plugins: {
    activities: ["transfers", "staking"],
    notifications: [
      {
        type: "email",
        config: { to: "investor@example.com" }
      }
    ]
  }
};

2. Wallet Backend

// Real-time push notifications for mobile wallet
const setup = {
  chainId: "westend",
  address: userAddress,
  plugins: {
    activities: ["transfers", "extrinsics"],
    notifications: [
      {
        type: "webhook", // Custom webhook to your backend
        config: {
          url: "https://your-api.com/push",
          headers: { "X-API-Key": "secret" }
        }
      }
    ]
  }
};

3. DeFi Analytics Dashboard

// Aggregate stats across multiple chains
const chains = ["polkadot", "kusama", "westend"];
for (const chain of chains) {
  const stats = await fetch(`/stats?chainId=${chain}`, {
    headers: { Authorization: `Bearer ${jwt}` }
  }).then(r => r.json());
  
  dashboard.render({
    totalTransfers: stats.transferCount,
    totalVolume: stats.totalAmount,
    avgTransactionSize: stats.avgAmount
  });
}

4. Governance Bot

// Alert on governance proposals
const setup = {
  chainId: "kusama",
  address: "validator-address",
  plugins: {
    activities: ["governance"],
    notifications: [
      {
        type: "discord",
        config: {
          webhook: "https://discord.com/api/webhooks/..."
        }
      }
    ]
  }
};
