A non-fungible token (NFT) based card game called Z-ERA has been exploited for $285,000, blockchain security firm CertiK reported on June 20.
CertiK said it discovered an exploit against Z-ERA’s BNB Smart Chain address in which an externally-owned account (EOA) deployed an unverified contract to steal funds.
The attacking address managed to obtain 1.8 million ZERA tokens, CertiK said. The attacker was then able to sell those tokens for about $285,000. CertiK further noted that the attacker had transferred 1178.5 BNB to TornadoCash.
Certik’s original report said that the incident caused the price of the ZERA token to fall by 99% but did not identify the actual price of the asset.
ZERA price tanks
Separate data from CoinMarketCap suggests that ZERA traded on Pancake Swap for $13.00 after its launch on June 19. The asset currently trades for $0.007 as of 10:00 p.m. UTC on June 13.
CoinMarketCap data also suggests that ZERA had a total circulating supply of 6.58 million tokens. As such, the 1.5 million ZERA theft affected about 27% of its supply.
The exploit occurred just days after the project announced the launch of its game and token on June 18. It launched an associated app days prior on June 15.
Z-ERA has not made any statement on the hack and CryptoSlate was unable to contact the project.
CryptoSlate contacted Z-ERA and CertiK for comments but had not received a response as of press time.
