Qube operates in the international market and develops solutions in the field of Web3, Blockchain, and smart contracts. The main project is an ERC20 token for investments and transactions.
In the blockchain sphere, security is of critical importance, as even a single vulnerability can lead to the collapse of a business. At risk of financial losses are not only the system owners but also the users.
In this case, we applied a White-box approach to smart contract auditing, which consisted of dynamic on-chain analysis and static code review. A manual line-by-line check of the code for vulnerability patterns was also performed.
To detect errors and vulnerabilities in the code and to verify compliance with coding standards, Datami specialists used audit tools Slither, Cloc, Oyente, SolHint. Testing was carried out in Remix, Ropsten testnet, MythX, and Manticore environments.
The project was carried out in a well-thought-out sequence. At the initial meeting with the client, all project details were agreed upon, after which the Datami team focused on a detailed smart contract audit.
After a complete review of all processes, the client received a detailed report with results, explanations, and recommendations.
Every
Datami verified the quality and security of the smart contract code before the mainnet launch: tested 4 contracts, conducted dynamic and static analysis, and performed a manual line-by-line code review.
We discovered a number of minor errors and ensured the absence of critical ones that could have caused the system to collapse immediately after launch due to the loss of investors’ assets and control over the contracts themselves.
As a result of the work, we prepared a detailed report with findings - the client received recommendations and answers to all key questions.
During the audit, the Datami team:
All assigned tasks were completed. The client followed our recommendations and was fully satisfied with the result.
In the blockchain sphere, there is no half-protection: either the system works flawlessly and the attack does not occur, or a single vulnerability leads to total losses. That is why an audit before launch is of critical importance.
As this case study demonstrates, thanks to the comprehensive smart contract audit, it was possible to eliminate potential threats to the blockchain solution. The client received confirmation of the code’s security and the system’s readiness for mainnet launch. Eliminating the identified issues became an important step for obtaining certification and releasing the project.

Among internet users, a long-standing myth has taken hold: if a website has the HTTPS mark - that is, a padlock in the address bar and the letter S after “http” - it means the resource is safe and trustworthy. But in reality, the situation is much more co
