The 2nd U.S. Circuit Court of Appeals has reversed Nathaniel Chastain’s fraud convictions. Chastain, a former product manager at OpenSea, no longer faces charges of wire fraud and money laundering. The case was significant because it was seen as the first insider trading case involving digital assets.

U.S Court Overturns Fraud Verdict 

According to reports from Reuters today, a court in Manhattan ruled that Chastain’s 2023 conviction was based on incorrect jury instructions. The court decided that the jury was wrongly told that acting dishonestly could be considered fraud. 

The case began in June 2022 when Chastain was accused of misusing OpenSea’s confidential data. As a product manager, he chose which NFTs to display on the platform’s homepage, which increased their value. He bought 45 NFTs before they were featured and later sold them for a profit. Chastain’s lawyers claimed that the information he used did not have commercial value, which was a key part of his defense.

The judges agreed with Chastain’s argument that fraud must involve hurting someone’s property interest, not just dishonest action. Chastain was originally convicted in May 2023, facing three months in prison and a $50,000 fine. In his appeal, filed in January 2024, he argued that OpenSea’s NFT information was not “property.”

Allegations and the Verdict

Prosecutors accused Chastain of using insider information for personal gain by purchasing NFTs before they were listed on OpenSea, anticipating price increases. Between June and September 2021, he reportedly made around $57,000 from selling 15 NFTs at significantly higher prices. To hide his actions, he used anonymous digital wallets and OpenSea accounts, marking this case as a notable example of insider trading in the digital asset space.

The court ruled on Chastain’s actions regarding the alleged theft of OpenSea’s confidential information, siding with Chastain. Unclear jury instructions suggested dishonesty could lead to a fraud conviction, causing the overturning of his convictions and highlighting legal uncertainties around NFTs.

Chastain’s lawyers expressed relief at the ruling, but there was no immediate response from the U.S. Attorney’s office in Manhattan. This decision has ignited discussions about NFT regulation and insider trading, with legal experts anticipating more clarity as digital asset cases progress. Chastain’s case is significant for the crypto industry.
