A chronological walkthrough of Ascendex Hack & GTH Token Contract Pause

On December 12th, Ascendex was hacked, and the hacker stole various tokens including GTH and the GTH token contract was paused as soon as possible. They informed us that their hot wallets were compromised. 8 Million GTH was moved from AscendEx to the hacker’s wallet.

After deliberating internally on the same day, at 12: 41 PM GMT +4 all token transfers have been paused. We had taken this measure as the hacker had not moved the stolen $GTH. We then did an internal strategy to move forward with a token redeployment method, keeping that in mind other exchanges had been notified about the paused contract and were informed about the hacker’s wallet to have it blacklisted.

On December 14th, we had a meeting with Ascendex for further damage control/reimbursements and then revealed the strategy of token redeployment and moved with the next steps.

On December 18th, for the users who are in the LP pool, a blog post was announced with all the instructions

A new contract was written, termed the LP recovery contract. This contract will only be accessed by LP multi-signature wallets & will allow Gather to withdraw tokens and optionally automatically re-deploy them to the new ETH Pool.

GTH Token Holders won’t have to claim or swap, Gather will Airdrop all tokens to existing holders.

By December 25th, 89.4% of Liquidity Providers successfully moved their existing LP tokens to two multi-signature contracts. A new deadline was announced of January 31st for the rest of the liquidity providers who have missed the first deadline, only with the removal option.

The main contract will be redeployed with the addition of a blacklisting function and making the contract upgradeable. In light of this event, we have engaged two different external security specialists to audit and periodically try to breach and conduct regular scans, all audits went smoothly in the last week of 2021 and are still ongoing.

Post the swaps and deployments, the original contract will remain frozen, hence leaving the hacker with no options to liquidate the stolen tokens.

BSC bridge will be launched following the days right after the redeployment along with other major updates. We have termed this redeployment date as D Day. D-Day is defined as redeployment & the launch of a new liquidity pool. Expect updates to happen in the next few days after go-live.

There will Also be LP Incentives for the BSC pool as well. All in all, even though the hack was unfortunate, we have been able to mitigate any loss of funds by freezing the contract.
