ERC-20 tokens. The vulnerability stemmed from an accounting flaw in the handling of released and revoked allocations within the VestingManager contract, which allowed manipulation of the system logic to extract funds locked by other users.

The incident triggered alarms because the affected contract still held more than $3.2 million in assets at the time of the attack. As an immediate containment measure, the UNCX Network team restricted the creation of new vesting positions and temporarily raised fees to 100 ETH to halt any further malicious interactions. They clarified, however, that individual locks and standard liquidity positions remain secure.
The market is awaiting UNCX’s final technical post-mortem along with mitigation and compensation measures for affected projects, while the attacker’s addresses remain under close on-chain monitoring.
