Project Description

SynthX is an intelligent Chrome extension that transforms Blockscout into an AI-powered investigation tool. Simply visit
any Blockscout page (transaction, address, or token) and SynthX automatically analyzes it using Claude AI, providing:

• Clear human-readable explanations of complex transactions
• Security pattern detection (compromised wallets, fund sweeping)
• Token verification status and metadata
• Safety scoring system for quick risk assessment
• Real-time analysis from comprehensive blockchain data

The extension fetches data from Blockscout's API and uses Claude's language model to generate insightful analysis that
helps users understand on-chain activity quickly. Perfect for traders, developers, security researchers, and anyone
navigating Web3.

How it's Made

SynthX is built as a Chrome Manifest V3 extension with three core components:

  1. Content Script (content.js) - Detects Blockscout pages and injects a dark-themed UI sidebar with safety scoring

  2. Background Service Worker (background.js) - Orchestrates data fetching from Blockscout's REST API and makes calls to Claude's API for analysis

  3. Claude AI Integration - Uses Claude 3.5 Sonnet to generate contextual analysis with smart prompts that understand blockchain patterns

Technologies: • Chrome Manifest V3 for security and modern extension standards • Blockscout API v2 for on-chain data (addresses, tokens, transactions) • Anthropic Claude API for intelligent analysis • Vanilla JavaScript with responsive UI design • Dark theme card-based interface for professional appearance

The extension analyzes token transfers, contract verification status, transaction patterns, and wallet behavior to provide actionable insights. Notable features include fund sweeping detection for compromised wallets and pattern analysis for trading behavior.
