The failed attack on Rainbow Bridge
According to Alex Shevchenko, CEO of Aurora Labs, in a detailed post, the attempt began on May 1, with the attacker deploying a contract that was supposed to deposit some funds to become a Rainbow Bridge relayer. The plan was to send fraudulent light client blocks. After a while, one bridge watchdog determined that the submitted block was not on the NEAR Protocol blockchain and sent a challenge transaction to Ethereum.MEV bots discovered this transaction and calculated that front-running it would result in a 2.5 ETH gain. As a result, the watchdog transaction failed, but the MEV bot transaction succeeded and rolled back the attacker's fabricated block, resulting in a 2.5 ETH loss for the attacker with no funds stolen. While the attack failed, the project will investigate additional security measures to make it more robust.
The significance of its design
Rainbow Bridge is a cross-chain bridge that enables users to transfer assets across the Ethereum, NEAR, and Aurora networks. When users want to transfer funds to Ethereum, the Rainbow Bridge is distinguished from other bridges by the presence of an Optimistic bridge. An optimistic bridge design includes independent parties monitoring network behavior; these observers were critical in protecting the Rainbow bridge.Another bridge with a similar design, Nomad, recently raised $22 million in a seed round, and it, too, uses optimistic proofs to secure its bridge. The attack marked the first time an optimistic bridge design was seen in action, demonstrating that it could be a solution to recent bridge hacks.

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 success guarantee work?
If our approach to the market doesn’t beat the overall crypto market during your subscription, we’ll give you a full refund of your membership fee. No questions asked. For quarterly and monthly subscribers this is applicable once your subscription runs for 6 consecutive months.
