Onchain Investigator ZachXBT Accuses Axiom Employee of Abusing Access for Insider Trading

Axiom is an on-chain crypto trading platform whose employees may have access to users' wallet and transaction data. ZachXBT alleged that employee Broox Bauer abused internal tools to track the private wallets of key opinion leaders, or KOLs, in an attempt to trade ahead of them for profit. The case highlights risks involving platform access controls and user privacy. The investigation did not disclose the amount of any realized profit.

As of July 19, 2026, ZachXBT had published his findings, alleging that Broox Bauer exploited an information advantage to engage in suspected insider trading. After the allegations surfaced, Axiom revoked his access to the relevant tools and launched an in-depth investigation. It has not disclosed the value of the transactions involved, the number of affected users, whether Bauer has been suspended or dismissed, or when the investigation will be completed.

ZachXBT is a pseudonymous on-chain investigator known for exposing crypto scams, hacks and insider trading.

On February 26, 2026, ZachXBT alleged that Axiom employees, including Broox Bauer, had engaged in insider trading since early 2025. After the allegations were published, the related Polymarket market resolved with Axiom as the answer. More than $9.7 million in contracts changed hands on the question, with total bets approaching $40 million, and one user made about $400,000. Axiom immediately revoked access to the tools involved, apologized and continued its investigation.
