Earlier today, there was an attack on our cross-chain bridging withdrawal via BNB Chain. Based on our investigations, the attackers managed to get the signature and minted 80M $WND on BNB Chain and traded through PancakeSwap for a total of 750 BNB which resulted in the sudden drop of $WND price.

  1. The team will be working round the clock to rectify the breach on our cross-chain bridge.
  2. Internal checks followed by a full audit will be conducted for the entire system to mitigate all threats and to prevent any future exploitation.
  3. A new contract for $WND will be created and the new $WND tokens will be airdropped to our token holders based on the snapshot prior to the attack , before block 16731166.
  4. WonderHero will compensate 100% to all liquidity providers of the WND-BNB LP pool prior to the attack.
  5. Once the above are completed, the new $WND liquidity pool will start for trading again. WonderHero website, marketplace, game and other services will resume.
  6. We will announce the timeline for recovery of services on a later date.
  7. A bug bounty program will be planned after the audit to better protect users.
