Smart Blockchain Monitor with ScrapeGraphAI Risk Detection and Instant Alerts

🎯 Target Audience

  • Cryptocurrency traders and investors
  • DeFi protocol managers and developers
  • Blockchain security analysts
  • Financial compliance officers
  • Crypto fund managers and institutions
  • Risk management teams
  • Blockchain developers monitoring smart contracts
  • Digital asset custodians

🚀 Problem Statement

Manual blockchain monitoring is time-consuming and prone to missing critical events, often leading to delayed responses to high-value transactions, security threats, or unusual network activity. This template solves the challenge of real-time blockchain surveillance by automatically detecting, analyzing, and alerting on significant blockchain events using AI-powered intelligence and instant notifications.

🔧 How it Works

This workflow automatically monitors blockchain activity in real-time, uses ScrapeGraphAI to intelligently extract transaction data from explorer pages, performs sophisticated risk analysis, and instantly alerts your team about significant events across multiple blockchains.

Key Components

  1. Blockchain Webhook - Real-time trigger that activates when new blocks are detected
  2. Data Normalizer - Standardizes blockchain data across different networks
  3. ScrapeGraphAI Extractor - AI-powered transaction data extraction from blockchain explorers
  4. Risk Analyzer - Advanced risk scoring based on transaction patterns and values
  5. Smart Filter - Intelligently routes only significant events for alerts
  6. Slack Alert System - Instant formatted notifications to your team

📊 Risk Analysis Specifications

The template performs comprehensive risk analysis with the following parameters:

Risk Factor Threshold Score Impact Description
High-Value Transactions >$10,000 USD +15 per transaction Individual transactions exceeding threshold
Block Volume >$1M USD +20 points Total block transaction volume
Block Volume >$100K USD +10 points Moderate block transaction volume
Failure Rate >10% +15 points Percentage of failed transactions in block
Multiple High-Value >3 transactions Alert trigger Multiple large transactions in single block
Critical Failure Rate >20% Alert trigger Extremely high failure rate indicator

Risk Levels:

  • High Risk: Score ≥ 50 (Immediate alerts)
  • Medium Risk: Score ≥ 25 (Standard alerts)
  • Low Risk: Score < 25 (No alerts)
