As many of you are already aware, $NUM was listed on Gate.io, KuCoin, PancakeSwap, and Uniswap on Thursday, November 18. We’d first like to thank you for the great interest in our platform’s native token, $NUM. The 24h volume was over US$50 million.
Today, we’d like to address an incident at the opening where some $NUM were prematurely available in the market, creating a low-liquidity pool on PancakeSwap.
Before going into more details, Numbers Protocol would send our appreciation to our partner, KuCoin, for the fast response and thorough investigation of this incident.
After a detailed investigation, we now know that it was due to a temporary system issue in KuCoin. According to the agreement, the withdrawal should not have opened until the next day (November 19). However, due to a KuCoin system upgrade on November 18, some users were allowed to withdraw $NUM unexpectedly. One user withdrew around 37.308 $NUM and created liquidity on PancakeSwap before we could.
When the PancakeSwap pool opened with extremely low liquidity, the Numbers Protocol team was immediately aware of this issue. We tried our best to add liquidity into the pool as quickly as possible, while simultaneously investigating the root cause.
In layman’s terms — A user unexpectedly received $NUM ahead of schedule, resulting in the user opening a pool with extremely low liquidity.
To understand how this happened, we traced back the transactions and found that the incident occurred through four transactions. We are sharing the transactions publicly so that everyone can verify what happened for themselves.
The four transactions are:
- Numbers sent 250 $NUM to the KuCoin contact window for CEX initialization.

This withdrawal (step 3) should not be allowed until 10:00 Nov 19 (UTC), and this unexpected withdrawal was the root cause of the incident.
A few minutes after listing, we became aware of the unexpected liquidity pool. We traced the transactions and found that the $NUM tokens came from a KuCoin wallet. We were shocked by the discovery because it simply should not have happened. After consulting with blockchain experts, we shared the results with KuCoin.
KuCoin was also shocked, but they immediately took responsibility and initiated an internal investigation. Several hours later, we were informed that they had figured out the incident was due to a temporary system issue, which led to the unexpected withdrawal. KuCoin was very responsive after we contacted them.
While we wanted to inform our community as soon as possible, it was important for us to first understand exactly what happened, as well as work with KuCoin to resolve it. We respected KuCoin’s decision to open an investigation and the time needed for internal discussions.
Again, we cannot thank our community enough for their support and understanding. The last few days were challenging, both for our team and our users, but we thank everyone for their patience as we work to resolve this unexpected issue.
We would also like to thank all the moderators of the local channels, and the moderators of the main channels for their support over the last few days.
For anyone affected by the incident, KuCoin will be providing a compensation plan after the investigation. Also, KuCoin is committed to launching a campaign with $NUM airdrop to reward users who have traded $NUM on KuCoin since trading opens.
Going forward, Numbers will be sharing an announcement for our very first $NUM airdrop, so please subscribe to our announcement channel and stay tuned.
Numbers is only as strong as our community, and though this was an unexpected issue, we saw firsthand how a common belief in something can bring everyone together. We appreciate everyone in our community, our team, and of course, everyone over at KuCoin who helped us resolve the issue as quickly as possible.
