Cryptolphin by CRYPTOLPHIN

Cryptolphin is a real-time crypto scam protection extension that works silently in the background while you browse. It protects you from the most dangerous threats in the crypto space before they can do any damage.
Every scam address in the database has passed a strict dual-verification process, independently confirmed by two separate and well-established data sources. No address is included on the basis of a single report. The pack currently contains 10,000+ verified scam addresses across ETH, BNB, Polygon, Arbitrum, Optimism, Avalanche and Fantom, and grows through scheduled releases.
