Zipcoin Shuts Down After Exploit, Plans Treasury Sale
Ethereum-based privacy project Zipcoin is shutting down after an exploit involving its locked tokens and a warning that its codebase and private keys may have been compromised. The alleged security breach has not been independently confirmed.
The crisis began on October 14, when an exploit in UNCX Network’s vesting contract enabled attackers to withdraw about 10.84 million ZC—roughly 1.1% of Zipcoin’s one-billion-token maximum supply—and convert the tokens into about 6.52 ETH. Zipcoin later used treasury funds to buy back tokens, but disclosed the buybacks only as it announced its closure. The team said a separate codebase compromise was discovered on October 21, leaving it unable to assure users that the code was safe.
Zipcoin gave holders a six-hour exit window before planning to sell about 22 million ZC, or 2.2% of supply, at noon U.S. Eastern Time on October 22. It has not said whether the proceeds will fund recovery or repayment. Stockereum, the launchpad involved in ZC’s distribution, has also sought the return of 12.66 ETH allegedly sent to Zipcoin’s foundation wallet; the repayment obligation is disputed, and no compensation plan has been announced.
ZC reportedly fell 84% within a day of the shutdown announcement. It had reached about $0.043 on October 4 and an estimated $40 million market capitalisation after launching in late September. The planned treasury sale and unresolved security and repayment issues add substantial uncertainty and could intensify selling pressure on ZC.
Bearish
The news is strongly bearish for ZC. The project is ending development after a token exploit and an unconfirmed warning about possible codebase and private-key compromise. These issues undermine confidence in the token’s security and the project’s ability to operate.
In the short term, the six-hour exit window and planned sale of 22 million ZC—about 2.2% of supply—could increase sell orders and volatility, particularly in a market already reacting to the shutdown. The reported 84% one-day decline indicates that traders have already repriced the risk sharply. The earlier theft of about 10.84 million ZC, the disputed 12.66 ETH repayment demand and the absence of a compensation or recovery plan may also discourage buyers.
Over the longer term, continued uncertainty about the security incident, treasury proceeds and outstanding obligations could limit confidence and liquidity. A price recovery would likely require credible details about the compromise, a transparent treasury-sale process and a clear resolution of the repayment dispute. Without those developments, ZC may remain under pressure; thin liquidity could magnify price moves in either direction.
