OpenAI is in talks to acquire Trail of Bits (ToB), a cybersecurity firm which counts top crypto projects among its clients, according to a Tuesday report by The Information.
The news comes in the wake of a major security incident at the AI giant’s offices, in which it discovered a “sophisticated recording device” in a conference room, planted by an engineer who’s since been arrested by the FBI.
ToB is one of the best known and well-respected auditors among crypto projects, with experience in nine blockchain ecosystems, and counting Arbitrum, Uniswap and Aave as clients.

While the increasing need for security expertise is clear, both within crypto and the wider AI industry, some find the potential for gatekeeping worrying.

Conversely, Yuga Labs’ 0xQuit called the move “extremely bullish” for crypto security, while another X user suspects OpenAI may be making a move into agentic crypto adoption.
A ToB audit is far from a rubber-stamp for safety, however.
DeFi projects audited by the firm have been exploited in the past, including Balancer and Bunni Finance, which lost $129 million and $8 million, respectively, last year.
Balancer has since decided to shut down.
