Analysis - Brahma.fi Contest

Approach

During my audit, I focused on understanding the mechanisms of Brahma, especially its signature verification, the interaction of the different accounts, and how it enhances the DeFi experience, My approach to this audit is as follows

• Read the Brahma docs.
• Understanding the different accounts and how they are related and work together.
• Read the contracts in scope line by line and understand every function and how they interact with each other
• Track the flow of the transaction execution process of each account and how the signature and committed policies are ensured.
• Write questions down (on how things can go wrong, and how a malicious user can go about causing harm to the protocol).
• Write down my issues found.
• Read the docs again, and research similar protocols and issues they usually face.
• Write my report.

I started by reading the documentation thoroughly to get a full grasp of the Brama protocol, what Brahma is and how they work. I spent time a considerable amount of time understanding how signatures and policies are verified as well as running different scenarios on how the validation can go wrong or be manipulated. In general, I believe the architecture of the protocol is foolproof especially the mechanism used in signature and policy validation, and the use of a double-layer screening of all transactions that is before and after execution is well thought out and great for security. As a whole, I consider the code execution to be excellent and its docs did well to express the intention and security consciousness of the developers, something worth noting would be the simplicity of the protocol and how the implementation of its functions is easy to understand there ensuring a better audit, I really had a good time auditing this protocol, below is my review of the different aspects of the codebase.

Centralization Risks

The protocol offers comfort to the user and removes any chance of a centralization risk as all transactions and approved accounts are all user-chosen addresses. It also ensures that console owners can override the safe guard at any time without obstruction leading to a fully user-controlled experience

Mechanism Review

The mechanism used for Brahma is well thought of as it brings comfort to the user while ensuring full authority over funds to users, The implementations are very easy to grasp and work very well as far as I can tell, and due to the nature of the protocol I think it should go by easily in terms of user adoption and security as signature, committed policies and each transaction are properly validated.

Systematic Risks

There is little to no systematic risk that poses any kind of threat whatsoever to the growth and longevity of the protocol, although the implementation of upgradable contracts would have served as an easy way to solve any unforeseen risks on deployment or that surface because of other external factors later on along the life cycle of the protocol.

Conclusion

I applaud the Brahma team for the creation of Brahma as it is a brilliant, well-executed idea to offer automation to frequent DeFi interactions that users execute this will encourage new participation into the defi space as it increases its ease of use.
