Crypto Sleuth ZachXBT Says Axiom Staffer Ran Insider Trades

Blockchain investigator ZachXBT alleged on Thursday that a senior employee at onchain trading platform Axiom Exchange abused internal access to user data to monitor private wallets and potentially conduct insider trading on memecoins. The claims, shared in a thread on X, center on Broox Bauer, a New York-based senior business development staffer at Axiom who purportedly used internal dashboards to look up sensitive wallet information and shared it with a small group tracking prominent crypto traders.

What Did ZachXBT Allege About Axiom?

ZachXBT claimed Bauer accessed an internal dashboard capable of revealing linked wallet addresses, referral codes, and user IDs tied to Axiom customers. In audio recordings shared in the thread, a person identified as Bauer purportedly stated he could look up "any Axiom user" by referral code, wallet address, or UID, and "find out anything to do with that person." The same recording describes initially researching 10 to 20 wallets before gradually expanding activity "so it does not look that suspicious."

ZachXBT said he had been retained to probe allegations of internal tool misuse, though he did not disclose who hired him. The investigator further alleged Bauer shared screenshots in April and August 2025 revealing private wallet data connected to specific traders, including linked addresses and registration details. A group reportedly compiled wallet addresses for multiple crypto key opinion leaders, or KOLs, in a Google Sheet drawn from Axiom's internal dashboard.

Several individuals named in the leaked material independently verified the accuracy of the wallet information, according to ZachXBT. The alleged strategy targeted traders known for accumulating sizable memecoin positions from undisclosed wallets before publicly promoting tokens. By uncovering those hidden wallets, the group could theoretically observe accumulation patterns and position ahead of anticipated price moves.

Axiom's Response and On-Chain Evidence

Axiom, founded in 2024 by Mist and Cal and a member of Y Combinator's Winter 2025 cohort, has generated more than $390 million in revenue to date, according to ZachXBT. The platform did not respond to media requests for comment but in a post on X said it was "shocked and disappointed" that a team member had abused internal customer support tools.

"We have removed access to these tools and will continue to investigate and hold the offending parties responsible," the company stated. "This does not represent us as a team, we have always tried to put the user first."

ZachXBT identified what he described as Bauer's primary wallet and mapped associated addresses, noting that funds flowed to multiple deposit addresses on centralized exchanges. He cautioned, however, that without access to Axiom's internal logs, establishing high-confidence examples of insider trading from on-chain data alone remains difficult.

We have removed access to these tools and will continue to investigate and hold the offending parties responsible.

Polymarket Odds Shift Toward Axiom

The allegations emerged amid broader scrutiny of trading practices across the crypto industry. Earlier this week, a widely tracked Polymarket bet on the identity of the firm under investigation shifted sharply toward Axiom, with the market generating more than $30 million in total volume.

Solana-based liquidity platform Meteora had been the leading candidate at roughly 43% odds earlier in the week, with Axiom, Pump.fun, Jupiter, and MEXC trailing at lower probabilities. As of Thursday European morning hours, those odds reversed and Axiom climbed to become the frontrunner at 35%, followed by Meteora at 26% and the "others" category at 15%.

What This Means Going Forward

Prediction market odds reflect aggregated trader sentiment rather than verified insight into underlying evidence or investigation outcomes. Even so, the sharp swing toward Axiom underscores how much attention this case has attracted across the crypto community.

The episode highlights persistent concerns around data privacy and internal controls at fast-growing onchain platforms. Whether Axiom's internal review corroborates ZachXBT's findings will likely shape user trust and broader industry standards for safeguarding customer wallet data.
