Blockchain project Ronin said on Tuesday that hackers stole cryptocurrency now worth almost $615m from its systems, in what would be one of the largest cryptocurrency heists on record.
The project said that unidentified hackers on 23 March stole 173,600 ether tokens and 25.5 million USD coin tokens. At current exchange rates, the stolen funds are worth $615m, but they were worth $540m at the time of the attack.
This makes it the second-largest crypto theft on record, according to blockchain analysis firm Elliptic.
Ronin is used to power the popular online game Axie Infinity, which uses non-fungible tokens (NFTs) and is the biggest NFT collection by all-time sales volume, according to NFT market tracker CryptoSlam.
