BlockBeats News, April 24th, SlowMist founder 余弦 (Yuxian) stated in a social media post that due to the leakage of a certain administrator's private key, $5 million worth of ZK was stolen from ZKsync. The funds have now been fully recovered.
ZKsync's unique sequencer is maintained by Matter Labs. Matter Labs intervened to freeze the hacker's address, limiting further transfers of 70% of the stolen funds. This action was taken because the stolen ZK directly impacts protocol governance.
