xToken loses $4.5 million in second major exploit
The xToken team tweeted that an attacker stole about $4.5 million worth of funds from xToken's xSNX product which lets users invest in Synthetix based assets.
How did this happen?
A postmortem posted by the project explained that the malicious actor took out a flash loan from decentralized exchange dYdX for 25,000 ETH to carry out the attack. They then used the Ether as collateral to borrow 1.5 million Synthetix Government Tokens (SNX) via Aave and Bancor.These were exchanged for 6.5 million USDC on the decentralized exchange Kyber, which pressured the price of SNX. The attacker then exchanged the USDC for Synthetix's USD token (sUSD) before exploiting a vulnerability in xToken's contracts to buy 614,000 SNX at an artificially depressed price of 811,000 sUSD.
Not the first time xToken has been exploited
The incident is the second time xToken has been exploited this year. In May, the protocol suffered from a similar exploit as a malicious actor manipulated Kyber DEX, taking advantage of xToken's price calculation. The breach cost the protocol around $25 million in SNX tokens at the time.The xToken team said it will work in the coming weeks to calculate investor losses and structure a compensation program based on the use of its native token.

Frequently Asked Questions
Can I trust Cryptonary's calls?
Yes. We've consistently identified winners across multiple cycles. Bitcoin under $1,000, Ethereum under $70, Solana under $10, WIF from $0.003 to $5, PopCat from $0.004 to $2, SPX blasting past $1.70, and our latest pick has already 200X'd since June 2025. Everything is timestamped and public record.
Do I need to be an experienced trader or investor to benefit?
No. When we founded Cryptonary in 2017 the market was new to everyone. We intentionally created content that was easy to understand and actionable. That foundational principle is the crux of Cryptonary. Taking complex ideas and opportunities and presenting them in a way a 10 year old could understand.
What makes Cryptonary different from free crypto content on YouTube or Twitter?
Signal vs noise. We filter out 99.9% of garbage projects, provide data backed analysis, and have a proven track record of finding winners. Not to mention since Cryptonary's inception in 2017 we have never taken investment, sponsorship or partnership. Compare this to pretty much everyone else, no track record, and a long list of partnerships that cloud judgements.
Why is there no trial or refund policy?
We share highly sensitive, time-critical research. Once it's out, it can't be "returned." That's why membership is annual only. Crypto success takes time and commitment. If someone is not willing to invest 12 months into their future, there is no place for them at Cryptonary.
Do I get direct access to the Cryptonary team?
Yes. You will have 24/7 to the team that bought you BTC at $1,000, ETH at $70, and SOL at $10. Through our community chats, live Q&As, and member only channels, you can ask questions and interact directly with the team. Our team has over 50 years of combined experience which you can tap into every single day.
How often is content updated?
Daily. We provide real-time updates, weekly reports, emergency alerts, and live Q&As when the markets move fast. In crypto, the market moves fast, in Cryptonary, we move faster.
How does the 3X Value Guarantee work?
We stand behind the value of our research. If the documented upside from our published research during your 12-month membership does not exceed three times (3X) the annual subscription cost, you can request a full refund. Historical context: In every completed market cycle since 2017, cumulative documented upside has exceeded 10X this threshold.
