OpenSea employee recently arrested for fraud

Recently, OpenSea’s former head of product Nathaniel Chastain was charged by the United States Department of Justice with one count of wire fraud and one count of money laundering.

According to the Department of Justice, Chastain used confidential information about what NFTs were going to be featured on OpenSea’s homepage for his personal financial gain.

He was subsequently arrested.

OpenSea CEO commits efforts against frauds

The company’s co-founder and CEO Derin Finzer then committed to stepping up efforts in preventing thefts, scams, and IP infringements on the marketplace.

Finzer said while plagiarism, IP infringements, and thefts are prohibited under OpenSea’s Terms, “at our scale, comprehensive policies were not enough.”

He said the company has launched a new verification system, that identifies authentic accounts and content more prominently to keep scammers out and that OpenSea’s copy mint prevention system is the most sophisticated spam and fraud reduction tool the company has built.
