Poly Network announced the hack on Twitter
Poly Network is a protocol for swapping tokens across multiple blockchains, including Bitcoin, Ethereum, and Ontology. The network tweeted just after the hack, "We are sorry to announce that #PolyNetwork was attacked on @BinanceChain @ethereum and @0xPolygon," and added, "We call on miners of affected blockchain and crypto exchanges to blacklist tokens coming from the above addresses."According to a source, the hack was caused by a cryptography issue, and because PolyNetwork is a cross-chain protocol, the hacker could steal large amounts of money. The assets stolen were $273 million of Ethereum tokens, $253 million in tokens on Binance Smart Chain, and $85 million in USDC on the Polygon network.
Tether has blacklisted the USDT that was stolen in the attack
Since the theft, Tether has blacklisted the USDT on Ethereum that was stolen in the attack, roughly $33 million in tokens. A person even warned the hacker that USDT was blocked, and for some reason, the hacker donated the wallet address that warned him for this $42k.The CEO of crypto exchange Binance tweeted Changpeng Zhao: "We are aware of the [poly. Network] exploit that occurred today. While no one controls BSC (or ETH), we coordinate with all our security partners to help proactively.
Slowmist announced it had already tracked down the attacker
Blockchain security firm Slowmist sent out a message saying it had already tracked down the attacker: ID. The company claims to know his email address, IP information, and fingerprint of his device. The company said the attacker's original funds were in Monero (XMR), which were exchanged for BNB, ETH and MATIC, and other tokens used to fund the attack.Slowmist said this information was obtained through its Chinese partner crypto exchange Hoo and other exchanges. Other crypto users have claimed that the funds used for the attack came from the Hoo exchange.

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.
