The Truebit protocol lost 26 million dollars due to an overflow error in its network code. This flaw allowed minting tokens at near-zero cost, activating the vulnerabilities in Truebit smart contracts recently. According to security firm SlowMist, the attacker drained the system’s reserves in an irreversible manner.
On one hand, the exploit originated from a lack of protection against integer overflows in the addition operation. The purchase contract produced incorrect results when calculating the Ethereum required for the transactions. The attacker took advantage of a “silent overflow” to reduce the minting price to zero immediately. This technical manipulation allowed extracting nearly eight thousand five hundred ETH from the protocol today.
Likewise, the use of the old Solidity 0.6.10 version facilitated the successful execution of this cyber attack. Calculations that exceeded the maximum allowed value simply reset near the null value. Because of this, the TRU token suffered a massive collapse in its valuation within the global market. The price dropped sharply from sixteen cents to levels near absolute zero very quickly.
On the other hand, the security firm SlowMist published an exhaustive analysis of the protocol’s logical errors. Liquidity reserves were emptied in a matter of minutes by the malicious actor. The Truebit team urged users not to interact with the currently compromised contract. Distrust seized investors due to the lack of critical security updates.
The challenge of technical security in legacy blockchain protocols
The relevance of this event highlights that even projects with years of history are susceptible to attacks. Truebit had been operating on the Ethereum mainnet for almost five continuous years. However, the vulnerabilities in Truebit smart contracts show that old code requires constant and deep audits. The DeFi sector faces a credibility crisis following the loss of institutional funds.
In addition, code flaws were the most used attack vector during the past year 2025. Almost thirty percent of cybersecurity incidents were due to serious logical errors. Therefore, developers must prioritize migration to much more secure and modern compiler versions. The cryptographic industry must learn from these mistakes to protect their users’ capital.
Is it possible to regain market confidence after a total price collapse?
On the other hand, the impact on the asset was devastating for long-term token holders. TRU’s market capitalization disappeared almost completely following the official report. Experts point out that rebuilding the reputation of a hacked protocol is an extremely complex task. Transparency in communication will be vital to mitigate the reputational damage caused by the exploit.
In this way, Truebit confirmed that it is working closely with authorities to track the stolen funds today. The attacker used privacy tools to hide the trail of the illegally seized assets. The technical team is expected to implement rigorous security patches in the coming weeks of development. The market remains attentive to the technical evolution of verified computing solutions.
