Smart contract audit of the Hubble Protocol by SmartState

Hubble Protocol is a DeFi protocol based on the Solana blockchain. It has its own special decentralized application (dApp), which provides the user with all the services in one integrated platform. It helps to streamline the user experience and avoid having to do excessive actions in order to perform an operation. In its current state the protocol allows users to deposit any type of combination of collateral assets. Hubble allows its users to borrow USDH and provides access to liquidity in long-term holding tokens. It combines and integrates various features into the platform, raising capital efficiency in different ways.

SmartState audits Hubble Protocol

Hubble had already relied on SmartState for audit services in the past. This time they approached us with a request for another audit of quite a long list of smart contracts. We have carried out a large number of tests of smart contracts and the platform architecture, analyzed them for best code practices, and studied the contract structure for possible issues and vulnerabilities, including:

- ERC20/BEP20 compliance

- Logical bugs

- Private data leaks

- Unchecked call return method

- Using components with known vulnerabilities

- DOS (General Denial of Service)

- Hidden malicious code

- Code with no effects

- Authorization issues

and others, which can lead to possible leaks or other problems.

About SmartState

Launched in 2019 and located in Dubai, SmartState is retaining the place of one of the leading DeFi security auditing companies. We carry out tests of security of the code core, smart contracts and blockchain for all types of errors or vulnerabilities.

Although SmartState triggered the operations with smart contract auditing of DLT-projects, from the very start we made our services go beyond the classic edges of understanding the smart contract audit and security check. We specialize in manual testing, so the SmartState’s tech team of white-hat security professionals carefully measures up a project’s git and supports clients with guidelines and recommendations for the further advancement. Security audit reports review the threats and vulnerabilities with which codebases may be exploited in the future, because the network achieves scalability and expands to accommodate more use cases and functionality.
