Blockchain and decentralized finance (DeFi) have revolutionized finance tech by placing control of assets and financial activities directly in the hands of users. As the DeFi ecosystem grows with revolutionary applications, the requirement for a secure blockchain protocol grows with it. One security measure that ensures a safe and sound blockchain is extensive smart contract audits, in particular as it pertains to the distribution of smart contracts.
These distribution smart contracts manage crucial features like token allocations, liquidity provision rewards, and yield farming incentives. They also manage the distribution of token/asset properties among participants and are thus a cornerstone to the very functionality of DeFi protocols. Robust distribution smart contracts are paramount.
Without them, the free flow of tokens or assets among participants could grind to a crippling halt, opening room for costly errors and inflicting substantial financial losses to participants, and tarnishing the name of the DeFi space at large, while also undermining user trust in the DeFi space. This is why the security of distribution smart contracts is so crucial and must undergo rigorous security audits to ensure the good health of the DeFi space as the industry matures.
Smart contract auditing is a thorough process aimed at identifying potential vulnerabilities, coding errors, or potential security flaws in the codebase, particularly for applications on DeFi platforms where trust dominates every aspect of the success of a given platform.
In DeFi, where decentralized networks give financial autonomy to users more than any other system has done, smart contract audits are pivotal in the security of distribution smart contracts. Distribution smart contracts are the ones that coordinate the flow of assets among participants.
As a result, the distribution smart contract audit process should be of a higher degree of evaluation than any other smart contract because the consequence of a vulnerability in its code could lead to catastrophic results.
Proper attention to token vulnerabilities is another key consideration that must remain front and center on the decentralized radar. A myriad of tokenomics challenges can arise, ranging from wrong token issuances/initial distribution to unauthorized minting. All of these challenges directly threaten the core principles of a decentralized ecosystem, as they call into question some of its central values such as openness, fairness, and integrity.
An incorrect token issuance/initial distribution can introduce distortions in project governance and user participation by skewing the balances of power underpinning the decentralized platform. A flawed token distribution can also bring about unfairness and compromise the level of trust that users can place in the system. Unauthorized minting can represent an unplanned source of inflation, affecting the stability and long-term value proposition of the ecosystem.
Distribution smart contracts are particularly vulnerable to ‘reentrancy’ attacks, and preventing these types of clever attacks bears heavily on the contract’s robustness. They allow an attacker to call functions inside a smart contract, changing the state of the contract recursively, after which it would be possible to drain assets from the contract before the original call finishes.
The attackers leverage recursive functions to execute multiple calls to the same function before the first call completes and thus change the state of the smart contract in a manner the project developers didn’t intend.
The dependency on oracles makes smart contracts fragile since the blockchain ecosystem has to contend with how oracles gather this data from the real world. Oracles are facilitators of information from the real world to the decentralized world of smart contracts. Oracles are essential mediators used by the blockchain as a tool to access ‘accurate’ real-world data to feed into the execution of the smart contract.
The problem with this dependency is that malicious actors could influence oracles so that they can provide inaccurate data for the execution of the smart contract’s function, or attempt to compromise oracles so that it could disrupt it.
having decentralized systems is front-running, a form of manipulation where a malicious user exploits the rules for sequencing transactions so that they gain an advantage over others who are participating in the same context. In this case, the malicious user’s transaction jumps the queue relative to normal transactions and takes precedence over others who’ve made transactions in the same platform, those whose transactions get queued thus having a lower priority.
This technique can leave the victim user with a negligible balance in their account or subject them to arbitrage by the front-runner. By making profits on price differences between these two transactions, the front runner capitalizes on the the risk between the time they place one transaction and the time it is executed against that other one, and trades against the victim user.
A key point lies in the fact that front-running takes advantage of a privileged position that the malicious user has because they manage to queue their transaction before the victim’s transaction and use that position to exploit other users in the blockchain. Indeed, users in decentralized systems should be able to participate without malicious individuals taking advantage of this order specification or the rules implemented in other smart contracts in the system.
For this, front-running risks must be mitigated so that these protocols can be trusted. Mitigating these forms of manipulation is thus a critical problem for maintaining the fairness of decentralised systems, the transparency of their operation, and the equality between participants who want to participate in these systems.
Because of rapid and escalating security risks within the world of ‘decentralized finance’ (DeFi), a current trend has DeFi projects and platforms turning to smart contract audit services to identify security vulnerabilities. These vital services are provided by blockchain security firms experienced in running tests on the underlying codebase, to identify security gaps in these self-executing contracts deployed by those in the DeFi sector.
This external audit includes a detailed review, using a combination of automated analysis and manual auditing to thoroughly evaluate the distribution smart contract. As these decentralized systems grow in complexity with each passing layer and evolve along with new variations of known threats, the role of these auditors is even more important. In having their smart contracts inspected by the expert audit team, DeFi projects can spot and patch vulnerabilities before attackers do, helping to strengthen the security posture of their platform.
This intense focus on scrutiny not only improves the odds for individual projects wanting to survive and thrive but helps make the entire DeFi ecosystem more stable and sustainable over time.
This process involves the granular examination of the distribution smart contract's code, line by line, to find potential security weaknesses and improve upon the contract’s logic, to prevent unintended actions by unauthorized parties.
This ‘code review’ process is fundamental because, in distribution smart contracts, every little intricate detail within a codebase could be a hole that malicious actors could exploit. They do not only look for the functionalities present, but they also analyze their logic. The goal is to detect vulnerabilities and any weaknesses that could undermine the security of the contract.
By making tangible recommendations for improvement, auditors help to make the smart contract more robust, giving developers and project teams the actionable insights they need to mitigate potential security vulnerabilities and establish a more secure and resilient platform for their dApps.
Functional testing is the most thorough phase of smart contract auditing and where the auditing firm will make sure that the end product is stable and works exactly as it should while using known attack vectors to test and strengthen the distribution smart contract. In this step, auditors review the functionality of the smart contract and make sure it all works as it’s supposed to.
This testing isn’t just about armchair assessments of a contract’s semantics and syntax, but also about testing for ‘real-world conditions’ and for known loopholes and threats ‘deemed likely to be exploited by real-world attackers.
Furthermore, the contract is scrutinized by experienced auditors to evaluate how well it adheres to all security-related best practices. This means examining the smart contract against the relevant industry standards and best practices to ensure compliance with standards that reduce common security vulnerabilities. Examples of this review include checking whether the code adheres to any coding conventions, the usage of cryptographic primitives and libraries, and the smart contract’s structural practices.
Through these best practices, the audit process aims to prevent any weakness in the smart contract that might compromise the integrity of the decentralized system. Thus, apart from seeking to assure users that the smart contract adheres to the current best security practices in the industry, the purpose of new audit services is also to proactively inform developers of any residual vulnerabilities or weak spots lurking in the system.
One of the main points to be considered when designing a distribution smart contract is how to optimize its gas usage. While this isn’t likely to be an issue for casual use, there are some projects – especially those being developed on blockchains such as Ethereum that charge transaction costs based on gas spending – where the list of ‘wasteful computations’ and redundant sections of code can be valuable to point out.
An auditor will take a look at the smart contract, and run through the codebase, looking for places where the code optimization can be made more efficient. It is the job of an auditor to review smart contracts for areas of repetition and code bloat that can be compressed.
So, by optimizing gas use, auditors make the smart contract both more economical and more efficient, in a way that advances the aims of the transaction and the user. The auditors’ clear-eyed devotion to gas efficiency is a factor that tends to enhance the viability and functionality of the smart contract both on the blockchain level and in the wider economy.
