The estimated losses from the UNCX Network token-vesting exploit have surged to approximately $1.49 million across four blockchains, nearly 17 times the $86,000 initially reported when the attack was detected on October 14, 2026.
Blockchain security firm Blockaid disclosed the revised figures on October 15, identifying 11 draining transactions involving BNB Chain, Ethereum, Robinhood Chain and Base. The investigation also found evidence of copycat attackers and maximal extractable value (MEV) bots participating in the exploitation of UNCX’s Vesting V2 contracts.
The expanded assessment significantly changes the scale of the incident, which initially appeared to involve a relatively small withdrawal-accounting vulnerability affecting several Ethereum-based tokens.
UNCX has confirmed that 10 tokens across four blockchains were affected but maintains that its legacy vesting contracts and liquidity-locking infrastructure were not compromised.
Blockaid Revises UNCX Exploit Losses From $86,000 to $1.49 Million
According to Blockaid’s October 15 investigation update, the exploit involved approximately $1.49 million in extracted assets across 11 draining transactions.
The security firm’s breakdown places the largest estimated loss on BNB Chain, which accounted for approximately $969,000, or nearly 65% of the total.
| Blockchain | Estimated Loss |
|---|---|
| BNB Chain | $969,000 |
| Ethereum | $242,000 |
| Robinhood Chain | $169,000 |
| Base | $114,000 |
| Total | $1,494,000 |
The figures represent Blockaid’s preliminary valuation of assets extracted through the identified transactions rather than a final accounting of realized attacker profits or recoverable customer losses.
The revised estimate follows the original UNCX exploit reported on October 14, when Blockaid identified approximately $86,000 removed from a shared Ethereum vesting pool through one transaction.
The October 15 findings show that the incident extended beyond that initial Ethereum transaction, with additional activity across three other networks.
Blockaid’s reconstruction also identifies transactions associated with other wallets and automated trading participants, indicating that the initial exploitation was not the only source of the estimated losses.
Copycat Attackers and MEV Bots Expanded the Incident
A notable feature of the revised investigation is the reported involvement of copycat attackers and MEV bots.
Copycat attacks occur when other participants identify a profitable exploit and attempt to reproduce it before the affected contracts can be secured. MEV bots, meanwhile, monitor blockchain transactions for opportunities to extract value through transaction ordering and execution strategies.
Blockaid’s investigation identified a transaction valued at approximately $152,000 associated with the Yoink MEV label, alongside smaller transactions categorized as copycat activity.
On BNB Chain, the BTCLE-related drain reportedly generated approximately 969,000 USDT. On Base, the principal identified transaction involved the IMO token, valued at roughly $114,000.
On Robinhood Chain, the investigation identified approximately $81,000 associated with CASHCAT and $78,000 involving RKST.
The inclusion of automated and opportunistic transactions matters because the total damage from a smart-contract vulnerability can exceed the amount extracted by the participant who first exploited it.
Nevertheless, the available findings do not establish that all 11 transactions were executed by unrelated individuals. Multiple addresses or automated systems do not necessarily represent distinct attackers.
UNCX Identifies 10 Affected Tokens and Restricts Vesting Activity
UNCX Network, formerly known as Unicrypt, provides cryptocurrency projects with token-vesting and liquidity-locking infrastructure. Its vesting contracts are designed to hold token allocations and release them according to predefined schedules.
Following the October 14 incident, the company identified 10 affected tokens across four networks.
Six were associated with Ethereum: PEPECOIN, EDGEN, ZC, X, LO0P and PAAL. The other affected tokens were IMO on Base, BTCLE on BNB Chain, and CASHCAT and RKST on Robinhood Chain.
UNCX said the vulnerability was isolated to its Vesting V2 infrastructure and that legacy vesting contracts and liquidity-provider token locks remained unaffected.
To contain the incident, the company introduced unusually high fees exceeding 1,000 ETH for new vesting locks, removed interaction routes that could bypass those restrictions and increased token-related fees to the contract’s maximum permitted level of 5%.
The measures were intended to make further exploitation economically unattractive while investigators examined the underlying vulnerability.
UNCX also said it was coordinating with security specialists and law enforcement, contacting affected token projects and preparing a detailed incident report and recovery plan.
At the time of its initial response, the project said attackers had not returned the extracted assets. No completed reimbursement arrangement has been established in the reviewed disclosures.
Researchers Point to a Vesting Share-Accounting Vulnerability
The suspected exploit mechanism involves how UNCX’s VestingManager contract records deposited shares and released tokens.
According to preliminary analysis by security researcher ExVul, the contract could reduce its global share count when tokens were released without making an equivalent adjustment to the shares recorded against an individual vesting position.
An attacker could potentially exploit that inconsistency by manipulating vesting positions, transferring tokens into the shared pool and subsequently cancelling a modified position.
The sequence could cause shares to be deducted more than once, altering the relationship between the pool’s token balance and legitimate user claims.
Under that interpretation, an attacker could withdraw tokens economically belonging to other vesting positions without directly compromising those users’ wallets.
The precise vulnerability remains subject to a final technical assessment. UNCX has not published a completed postmortem independently establishing every step of the suspected attack.
Why the $1.49 Million Figure Needs Careful Interpretation
The jump from $86,000 to almost $1.5 million is dramatic, but investors should distinguish between estimated asset values, actual sale proceeds and the final losses suffered by affected users.
The distinction is especially relevant when exploits involve tokens with limited trading liquidity.
An earlier on-chain investigation by PublicAML found that assets valued at approximately $86,000 in the initial Ethereum exploit generated about 14.93 ETH, worth approximately $36,000, through identified sales at the time of its analysis.
That difference illustrates why the market value of withdrawn tokens may substantially exceed the amount an attacker can convert into liquid assets.
A similar valuation problem emerged in the revised Autheo exploit investigation, where on-chain analysis distinguished unauthorized token issuance from the considerably smaller amount realized through actual sales.
For UNCX, the revised estimate includes different valuation methods across the affected chains, making a direct comparison with realized cash proceeds inappropriate.
The $1.49 million remains a useful measure of the incident’s reported scale, but it should not be mistaken for a confirmed amount of attacker profit.
Shared Vesting Infrastructure Creates Risks Beyond Individual Tokens
The broader concern is that token-vesting services are meant to provide investors with assurance that certain allocations cannot enter circulation before their scheduled release dates.
That assurance becomes weaker when a flaw in shared accounting allows one participant to interfere with assets attributed to other positions.
Investors examining tokenomics often focus on the amount of supply scheduled to unlock each month. They may pay less attention to whether the underlying vesting contract accurately preserves ownership claims under unusual transaction sequences.
The UNCX incident demonstrates why those are separate questions. A vesting schedule can look entirely legitimate while the smart contract enforcing it contains an exploitable accounting inconsistency.
The involvement of multiple blockchains adds another complication.
Deploying the same or similar contract logic across several networks can increase operational efficiency, but it may also reproduce a vulnerability across multiple ecosystems.
Once a working exploit becomes visible on one chain, other participants can examine comparable deployments for the same weakness.
Automated market participants can potentially accelerate that process. Dave Finances recently examined the growing influence of automated bots across decentralized trading markets, including their role in extracting value from liquidity and transaction flows.
Although that investigation concerned different activity, it illustrates how quickly automated strategies can influence outcomes when profitable on-chain opportunities emerge.
Containment Is Not the Same as Fixing the Vulnerability
UNCX’s decision to impose extremely high interaction fees may help discourage additional exploitation, but it does not necessarily demonstrate that the underlying accounting issue has been repaired.
If the suspected flaw remains in existing contracts, investors need to know whether previously created positions can still reach the vulnerable execution path.
There is also a practical problem for legitimate users. Emergency restrictions intended to protect remaining assets may temporarily complicate normal vesting operations.
That trade-off is understandable during an active security incident, but it creates pressure to deliver a technically sound recovery process rather than relying indefinitely on restrictive fees.
The next meaningful update should reconcile the 11 identified draining transactions, establish the outstanding liabilities to legitimate vesting participants and distinguish assets that were sold from those still held by identifiable addresses.
Any reimbursement arrangement would also need to address how losses are allocated among affected token projects and individual beneficiaries.
UNCX’s assertion that liquidity locks and legacy vesting contracts remain unaffected is reassuring, but a completed independent security assessment would provide stronger evidence of the limits of the incident.
Ultimately, the revised $1.49 million estimate changes the story from a relatively small Ethereum exploit to a broader failure affecting several blockchain ecosystems.
For investors, the most important question is no longer simply how much was extracted. It is whether UNCX can demonstrate that the remaining vested assets are properly backed, the vulnerable accounting path has been eliminated and legitimate token-release schedules can once again be trusted.
