To protect the world from social engineering attacks every day.
While the NFT space is often one that is enticing to investors and traders, there are persistent issues with fraud in the market. Cybercriminals are able to pass off any image as their own intellectual property, and while NFT marketplaces do abide by copyright laws this kind of fraud can be hard to spot before money changes hands. The damage to a brand's reputation and customer trust can be hard to rectify.
Doppel exists to solve this problem. Using an AI model trained to spot fraud and IP violations, it indexes NFT data across most of the major blockchains and flags potentially fraudulent NFTs. Trusted by Opensea, Dapper and numerous other marketplaces, Doppel scans over 1.5 million NFTs daily and has identified over 100,000 threats in the marketplace.
Doppel has raised significant funding, its 2025 round aimed at accelerating product innovation and expanding its capabilities beyond NFT fraud detection into broader social engineering defense. As AI-driven scams become more sophisticated, the company is ready as a multi-channel security platform, helping organizations detect, prevent, and respond to threats across digital environments.
