Eisenberg KYC’d as a Ukrainian Woman on a Crypto Exchange to Carry out the Mango Markets Exploit

Validated Media

The fine print of court documents detailing the arrest and charging of the Mango Markets exploiter with fraud and market manipulation has revealed previously unnoticed details of how he carried out his scheme of profiting from the manipulation of the MNGO/USD perpetual contract.

Eisenberg Used a Crypto Account Verified Using the Credentials of a Ukrainian Womanmango

According to the statement of Federal Bureau of Investigation (FBI) Special Agent Brandon Racz, the defendant, Avraham Eisenberg, opened an account on a crypto exchange around September 19th 2022, ‘using a passport and personal identifying information that appears to belong to a Ukrainian woman, along with a particular Gmail address.’

He added that the Gmail account was created ‘on or about September 1st 2022,’ with a recovery email of [email protected] and a phone number, both belonging to Avraham Eisenberg.

Special Agent Racz explained that Eisenberg used the trading account to receive 12 million USDC, then sold for over 16 million MNGO. This trade caused the price of MNGO to rise from $0.0388 to a peak value of $0.1557, kickstarting the sequence of events that led to Mango Markets DeFi protocol losing an estimated $114 million.

Eisenberg’s Case Highlights a Common Practise of Individuals Purchasing Verified Crypto Trading Accounts

Eisenberg using a trading account verified using the information of a Ukrainian woman, brings to light an often-used technique of traders buying crypto exchange accounts to circumvent jurisdictional restrictions.

Such incidences were common when Bitmex and Binance started banning US crypto traders from their platforms due to regulatory pressure from the CFTC and SEC.

The purchased verified accounts were then used alongside a stable VPN to access the blocked trading platform, providing access to tokens and services such as futures trading, usually prohibited in the United States.

Americans Who Traded on FTX International Using Fake Accounts Might Not Get Compensated — Su Zhu

Su Zhu, the co-founder of defunct crypto hedge fund Three Arrows Capital, has also chimed in on the fact that Eisenberg used the credentials of a Ukrainian woman to trade on a crypto exchange.

Mr Zhu pointed out that Americans most likely used fake KYC credentials to trade on FTX, concluding that they might not get compensated once the bankruptcy proceedings are over.

‘One reason I’m pretty bullish on FTX claims is [because] people are vastly underestimating what % of Americans who traded on FTX did so with fake KYC. These people won’t even be able to file claims,’ Su Zhu explained in a Tweet.

  • Crypto-Friendly Bank Erebor Seeks $1.5B Funding with a16z Participation

    On August 11, Erebor Bank, a crypto-friendly bank co-founded by Oculus and Anduril founder Palmer Luckey and Palantir co-founder Joe Lonsdale, is seeking $1.5 billion in funding, with a pre-money valuation target of $8 billion. This valuation is nearly double the $435 million valuation the company had when it completed a $350 million funding round in December 2025. Erebor has already received support from investment institutions such as 8VC and Haun Ventures, and the new funding round is expected to attract participation from Lux Capital, Andreessen Horowitz (a16z), Human Capital, Valor Equity Partners, and SV Angel, among others. As AI infrastructure investment enters a phase of rapid expansion, Erebor is targeting the financing needs of AI companies. AI companies require substantial capital to purchase GPUs, build data centers, and secure energy supplies, while traditional financial institutions are gradually exploring financing models for AI infrastructure assets. However, whether Erebor can maintain rapid growth after the AI and crypto industry cycles cool down remains a key focus for the market. The funding round has not yet been finalized and is expected to be completed within the coming weeks.

  • Vitalik Updates Ethereum Roadmap: Privacy, Post-Quantum Scaling, and Native Rollups Become New Priorities

    On August 10, Vitalik Buterin stated that he had compared the 2023 Ethereum roadmap with the current Strawmap. The overall direction still overlaps considerably, but some priorities and technical paths have been clearly adjusted, including raising the priority of quantum safety, downweighting VDF and some EVM improvements, and replacing old designs with solutions such as a unified binary tree, PBT, and new state types. He noted that the most notable change in the current Strawmap is the emergence of several new topics not included in the 2023 roadmap, reflecting a shift in Ethereum's R&D focus. These new priorities include: stronger native privacy support, aggressive scaling in a post-quantum context, specification streamlining for formal verification, Blob and Gas futures, native Rollups, and a more open design space for the future shape of the EVM. Vitalik also emphasized that Ethereum's scaling approach is shifting from 'expanding all activities comprehensively' to 'designing more scalable dedicated mechanisms for specific high-load scenarios,' and he regards STARK proofs and AI-accelerated formal verification as important foundations for the protocol's future. Overall, this update shows that the Ethereum roadmap is evolving toward quantum safety, privacy-first, censorship resistance, high performance, and simpler protocol design.
