Security Concerns Surrounding Tact Language in TON Blockchain
CertiK, a leading blockchain security firm, has issued a cautionary report regarding vulnerabilities associated with Tact, the innovative programming language tailored for crafting smart contracts on the TON blockchain. Released on Thursday, the audit sheds light on potential security risks that developers may encounter, particularly as the TON ecosystem continues to expand.

The Tact Programming Language: Opportunities and Risks
Tact was introduced in 2023 with the aim of simplifying the development process while enhancing performance and security in the smart contract landscape of the TON blockchain. However, despite its promising features, CertiK’s findings reveal several vulnerabilities that can compromise developers’ efforts and user funds.
In the audit, CertiK drew comparisons between Tact and its predecessor, FunC, pinpointing a variety of common coding errors that could plague developers. These mistakes not only threaten the integrity of the smart contracts but also pose significant risks, including transaction failures and potential loss of funds.
Key Vulnerabilities Identified in the CertiK Report
Among the most pressing concerns outlined in the report is Tact’s stringent address format. Unlike standard practices defined in TEP-74, deviations could lead to transaction failures or lost tokens – essentially analogous to misdirecting a letter due to an incorrect address.
Additionally, CertiK highlighted challenges arising from managing concurrent operations on the TOM blockchain. Although TON is designed to mitigate vulnerabilities like reentrancy – often seen on Ethereum – the unpredictable nature of transaction ordering may leave room for attacks that exploit timing discrepancies, akin to man-in-the-middle vulnerabilities.
The complex nature of TON’s asynchronous and parallel processing makes tracking action order quite challenging.
The Importance of Data Serialization and Gas Management
Another critical area of concern involves data serialization. CertiK emphasized that developers must meticulously organize data within their smart contracts. Overlooking this step can lead to misinterpretations, resulting in erratic program behavior – much like attempting to assemble furniture without complete instructions.
Moreover, managing “gas” – the essential fee required to facilitate blockchain transactions – emerged as a significant focal point. Improper estimation of gas can not only lead to transaction failures but also risk draining funds from smart contracts, highlighting a need for vigilant management by developers.
The Broader Crypto Security Landscape in 2024
While Tact’s vulnerabilities are concerning, the overall cryptocurrency environment in 2024 is marked by alarming security challenges. According to a recent report by Immunefi, nearly $1.5 billion has already been siphoned off in crypto-related incidents this year, despite a notable 15% decrease in stolen amounts compared to 2023.
Crypto losses from October to November 2024 have illustrated the ongoing threats in the space.
Noteworthy incidents in November include a security breach at the meme coin trading terminal DEXX, stemming from a private key leakage that affected at least 900 users. While most victims experienced losses below $10,000, one unfortunate user reported a staggering loss exceeding $1 million. In another incident, Delta Prime, a decentralized finance protocol active on Avalanche and Arbitrum, fell victim to its second significant exploit this year, suffering a loss of $4.8 million.

Why It Matters
The revelations from CertiK’s audit of Tact serve as a critical reminder for developers in the blockchain arena. With cryptocurrency theft and exploits remaining rampant, understanding and addressing these identified pitfalls is essential for ensuring the safety and reliability of smart contracts. As the technology develops, so too must the vigilance of those who build upon it.
Expert Opinions
Experts in the field have echoed the importance of adopting secure coding practices, urging developers to prioritize security in the software development life cycle. “Understanding the underlying mechanics of the programming language is crucial,” notes a cybersecurity analyst from CertiK. “Mistakes can prove costly both in terms of financial loss and reputational damage.” This expertise underscores the necessity for continuous learning and adaptation as developers navigate the evolving blockchain landscape.
Looking Ahead: The Future of Tact and TON
As the TON ecosystem matures, addressing the vulnerabilities highlighted in the CertiK audit will be vital for fostering a robust development environment. Continuous updates to Tact, enhanced educational resources for developers, and improved security protocols will be essential for minimizing risks and ensuring the success of smart contracts on the blockchain.
Overall, the findings serve as a clarion call for all stakeholders in the cryptocurrency sector, emphasizing the importance of security as a cornerstone of innovation in blockchain technology.
