Tigris Protocol ANN — Double Withdrawal Bug Fixed

TTC | 10.09| 107

Tigris Protocol ANN — Double Withdrawal Bug Fixed

A double withdrawal bug found within the unstaking function of Tigris Protocol has been fixed and updated

The TTC Foundation discovered and fixed a bug related to the unstaking function of Tigris Protocol which lasted for 3 days from October 4th thru the 6th, Singapore time. The bug was not detected during internal testings and external institution audits of Tigris Protocol; nonetheless, the related smart contract has been upgraded, promptly.

Here are the details related to the bug. (The shared timeline are based in Singapore time.)

  • 2019/10/4, 08:00: Double withdrawal case occurred when unstaking was commenced
  • 2019/10/7, 10:00: Withdrawal function temporarily suspended
  • 2019/10/8, 15:00: Smart contract upgrade complete
  • 2019/10/8, 20:00: Withdrawal function restored

The currently fixed bug made it possible for users to double withdraw their “Staking Rewards” during its undetected period. The loss that occurred due to the bug, calculated conservatively, is estimated to be 22,371 TTC (approx. 900 USD) at most while the actual loss ranges between 10,000~15,000 TTC (approx. 400~600 USD). As a result, the TTC Foundation has allocated 22,371 TTC to the Tigris Reserve from the fund allocated to the Foundation.

Tigris Protocol is now fully functional and the Foundation is thoroughly and constantly rechecking the smart contract for further stabilization. In case there are follow up updates, we will officially announce the details via our official channels. We apologize for the delay in dealing with the issue as the bug was discovered when the dev team was away for the holiday. The team had to assess the situation precisely and with clarity, thus, we also apologize for announcing the situation later than expected. We thank you for your support and understanding.

Thank you.

If you have any further questions, please contact us through our Telegram group or email.
