Badger DAO, a Bitcoin-focused decentralized finance project built on the Ethereum blockchain, has been drained of roughly $100 million as a result of a nasty front-end attack.
A single user has lost 896 BTC (roughly $50 million), according to blockchain security company PeckShield.
In a Twitter statement, the team has acknowledged reports of unauthorized withdrawals, adding that its engineers are investigating the issue.
The protocol's smart contracts have been temporarily halted.
According to data provided by DeFi Pulse, Badger DAO is the 23rd biggest DeFi protocol on Ethereum. Last month, it topped $1 billion in total value locked.
The hack happened just days before the yield vault protocol's one-year anniversary.
BADGER, the native token of the Badger DAO project, is down 15.3% on the news, according to CoinGecko data.
