Powerful Features

Everything you need to verify wallet addresses and stay safe in Web3.

Multi-Chain Address Scanner

Paste any cryptocurrency wallet address and receive an instant risk analysis. Supports 9 major blockchain networks: Ethereum, Bitcoin, TRON, Solana, Litecoin, Ripple, Dogecoin, TON, and Cosmos.

Intelligent Risk Scoring

Every address gets a score from 0 to 100, calculated from format validation, checksum verification, entropy analysis, transaction patterns, and cross-referencing against known scam databases.

Real-Time Web Page Scanning

Automatically detects cryptocurrency addresses on any web page you visit. Addresses are highlighted inline with a subtle indicator. Works on social media, forums, DeFi platforms, and everywhere else.

Right-Click Context Menu

Select any text on a web page and right-click to scan it with CryptoScan instantly. No need to open the popup - get a risk score notification right away.

Personal Watchlist with Monitoring

Save addresses to a persistent watchlist. CryptoScan automatically checks your watchlisted addresses every 30 minutes for balance changes and sends you a notification when activity is detected.

Built-in Scam Database

Includes a curated database of known malicious wallet addresses: confirmed scammers, phishing drainers, rug-pull deployers, and suspected mixers. Instantly flags any match with a critical warning.

Scan History & Statistics

Every scan is logged locally with full details. Search past scans, view risk distribution by network, analyze trends over time, and see your most scanned addresses.

On-Chain Data Retrieval

Fetches real balance, transaction count, and first-seen date from public blockchain APIs with built-in caching and retry logic. Displays data in a clean metadata grid directly in the scan results.

Security Notifications

Receive system notifications when a known dangerous address is detected on a page, when a context menu scan completes, or when watchlist monitoring finds balance changes.

Data Export & Import

Back up your entire watchlist, scan history, and settings as a JSON file. Restore from backup or merge data at any time. Your data, your control.

Blockchain Explorer Integration

One click takes you to the full on-chain history via the appropriate blockchain explorer - Etherscan, Mempool.space, TronScan, Solscan, and more.

Beautiful, Privacy-First Design

Premium dark theme with glassmorphism, particle animations, and smooth transitions. Zero external data collection, no tracking, no account required.

Your Data Never Leaves Your Device

CryptoScan operates entirely locally within your browser. Risk analysis is performed on your device. Only wallet addresses are sent to public blockchain APIs to fetch on-chain data - no personal information is ever transmitted.
