Levyathan developers stored private keys with minting capability on GitHub. The attacker used these to pass a timelock transaction on July 28 and execute an ownership transfer on July 30, minting 100 quintillion LEV tokens. The weak timelock controls lacked multisig authorization.

Levyathan, the encryption index protocol on the BSC chain, was attacked. According to the official event update, the hacker minted 100,000,000,000,000,000,0 billion LEV tokens, which caused the price of LEV to return to zero. The loss of this attack was approximately USD 1.5 million. The official attributed the accident to the leak of the developer's private key.
