SlowMist Flags Reported $86,000 UNCX Token Loss Linked to VestingManager Flaw
Key Takeaways
- •SlowMist flagged an estimated $86,000 loss of UNCX Token allegedly connected to a flaw in the cancellation of a VestingManager contract.
- •The alert does not include verified transaction data, a confirmed attacker address, or an official statement from the UNCX project, so the incident remains unconfirmed.
- •Vesting contracts automate scheduled token distributions, and their cancellation functions can create security risks when they are not properly restricted or validated.
- •UNCX Token is associated with the UniCrypt platform, whose shared vesting and liquidity-locking infrastructure serves many projects, potentially broadening the relevance of the reported flaw.
- •SlowMist has previously reported similar contract-level issues, including a 5.08 ETH loss involving Set Protocol and a 114.09 ETH loss tied to an Aave v3 Loop Safe Module.

Blockchain security firm SlowMist has flagged a reported loss of approximately $86,000 in UNCX Token, allegedly linked to a flaw in the cancellation logic of the protocol’s VestingManager contract. The report attributes the incident to a vulnerability in the way vesting schedules can be cancelled. However, the available information does not include independently verified transaction details, a confirmed attacker address, or an official response from the UNCX project team.
SlowMist reports an $86,000 UNCX Token loss
According to SlowMist’s alert, the reported loss involved UNCX Token and was connected to a cancellation-related issue in the protocol’s VestingManager component. SlowMist monitors on-chain activity and smart contract behavior across multiple networks and published the report as part of its ongoing security monitoring.
The $86,000 figure appears in SlowMist’s alert as an estimated loss amount. The available research does not include a block explorer transaction hash, wallet address, or on-chain data independently confirming the figure. The amount should therefore be treated as reported rather than verified.
SlowMist has previously flagged similar contract-level issues. These include a reported 5.08 ETH loss tied to a calculation issue in Set Protocol’s actualizeFee function. The firm also previously identified an issue in an Aave v3 Loop Safe Module that reportedly resulted in a loss of 114.09 ETH. In such cases, SlowMist’s alerts serve as early warnings pending further confirmation from the affected projects.
The alleged VestingManager cancellation flaw
Vesting management contracts govern the release of tokens to recipients according to a defined schedule. Such contracts are a standard piece of decentralized finance infrastructure, commonly used to automate team, investor, and community token distributions, and cancellation functions generally exist so that schedules can be terminated under defined conditions before full release. Cancellation functions in these contracts can create security risks if they are not properly restricted or validated.
SlowMist’s report links the alleged UNCX Token loss to a flaw in the cancellation logic of a VestingManager contract associated with UNCX Token. The available information does not identify a specific function, code path, or exploit sequence.
The research also does not establish whether the alleged flaw involved improper controls, a reentrancy condition, or incorrectly calculated token accounting during cancellation. Those technical details would typically be addressed in a formal post-mortem or audit report, but neither has been referenced in the current alert.
Implications for UNCX holders and protocol users
UNCX Token is associated with the UniCrypt decentralized finance platform, which provides token vesting and liquidity-locking services. Vesting and locking providers typically operate shared infrastructure that serves many token projects at once, so an unconfirmed flaw in a single vesting component can be relevant to any project or recipient relying on the same contracts. A vulnerability in a vesting-related contract would be directly relevant to projects and individuals relying on UniCrypt’s VestingManager for token distribution.
Users and project teams should monitor the official UniCrypt and SlowMist channels for confirmation of the reported vulnerability and information about any remediation steps. Developments worth watching include an on-chain record that corroborates the $86,000 estimate, a formal post-mortem or audit report identifying the affected code path, and an official statement from the UNCX team describing any patch or contract change. The available information does not include a recovery outcome, patch deployment, or official statement from the UNCX project team.
Until a formal response is published, both the reported $86,000 loss and its alleged cause should be treated as unconfirmed. Readers should verify the details through SlowMist’s published alerts and any subsequent disclosures from the UNCX team before drawing conclusions about the protocol’s current security status.
