Hacked Accounts Recovered as ZKsync Team Shuts Delegate Access

• ZKsync and Matter Labs quickly regained control of their official X accounts after a hack via compromised delegate access.
• The team disconnected all delegate apps and continues investigating the source of the unauthorized access.

Chaos. That was the first impression when the official X account of ZKsync and Matter Labs suddenly shared a suspicious announcement today, May 13, 2025. It wasnt just a typo or a random tweet—the account spread fake news that ZKsync was being targeted by the SEC and the US Treasury Department.

Worse still, a fake link about an airdrop was also spread, luring users to click on a page whose security was unclear. Many were immediately suspicious, some were already fooled.

ZKsync Team Moves Fast After Account Hack

It didn‘t take long for the ZKsync team to take action. They confirmed that the hack occurred via a delegate account that had been given limited permission to access the main account. It’s similar to when someone lends a spare house key to a trusted person—and it turns out that the key holder is actually a leak.

As a result, all connections to the delegate accounts were immediately cut off. All posts from the hacker were deleted completely.

The ZKsync and Matter Labs X accounts are fully back in the control of the team. Were looking into how the accounts were hacked, and believe it was through compromised delegated accounts.

All delegated accounts and connected apps have been disconnected, and weve deleted any…

Sharp Token Drop Follows Hack, Even as Tech Moves Ahead

Just imagine if you had just heard news about a rapidly developing project, then saw that its official account was announcing a major legal issue. Would you panic？ This does have quite a noticeable impact. The price of the ZK token reportedly dropped in just a matter of hours. Previously, the token had just risen by almost in the last 7 days and swapped hands at about $0.071.

However, behind this incident, there is another progress from ZKsync that is quite interesting. On the other hand, CNF previously reported that the ZKsync network is now fully equivalent to the EVM—not only at the programming language level, but also down to the bytecode level. This allows Ethereum smart contracts to run directly on ZKsync without additional tools. ZIP-9, an important governance proposal, is what drove this change.

Furthermore, ZKsync also seems to be focusing on strengthening its technological foundation. Last March, they introduced ChonkyBFT, a new consensus protocol designed to improve transaction efficiency and security.

This system allows finality in a single vote, even resistant to nodes that behave badly as long as the number is still within the tolerance limit. A step that cannot be underestimated in the blockchain space.

Still on the development track, on May 7, 2025, ZKsync also announced integration with QuarkID—a blockchain-based digital identity system. The goal？ Empowering over 3.6 million citizens to access digital services with secure and more efficient identities. Imagine if in the future, KYC verification in the crypto world could be as easy as opening a mobile phone.

Although the hacking incident had shaken public trust, all the recovery and transparency steps taken by the ZKsync team show that they are not only focused on building technology, but also protecting the ecosystem and its users.
