What are the risks of using flash loans in DAOs?

Flash loans are a type of smart contract that allow users to borrow large amounts of crypto assets without collateral, as long as they repay them within the same transaction. They are often used to exploit arbitrage opportunities, liquidate undercollateralized positions, or manipulate prices in decentralized exchanges. However, flash loans also pose significant risks to decentralized autonomous organizations (DAOs), which are self-governing entities that run on blockchain protocols and execute rules through smart contracts. In this article, we will explore some of the main risks of using flash loans in DAOs, and how to mitigate them.

1 Attack vectors

One of the biggest risks of using flash loans in DAOs is that they can enable malicious actors to launch sophisticated attacks on the underlying protocols, governance mechanisms, or incentive structures of the DAOs. For example, in November 2020, an attacker used a flash loan to drain $6 million worth of DAI from the Value DeFi protocol, by exploiting a flaw in the price oracle that determined the value of the collateral. Similarly, in March 2020, an attacker used a flash loan to manipulate the price of MKR, the governance token of MakerDAO, and acquire a large amount of voting power, potentially threatening the stability of the protocol. Flash loans can also be used to create artificial demand or supply for certain tokens, influence the outcome of proposals, or sabotage the reputation of competitors.

Price oracle attacks are another significant risk of using DAOs in flash loans. Flash loans can be used to manipulate the price oracles that DeFi protocols rely on for pricing assets. An inaccurate price feed due to a flash loan attack could cause a DAO to make erroneous transactions or judgements.

There are certain risks associated with flash loans that you should be aware of. Front-run happens when a trader exploits the market using inside information. An arbitrage opportunity with a flash loan is a great opportunity. However, there is a possibility that you will be front-run. Remember how I mentioned that if a transaction fails to execute, it will be rolled back instantly? Now, with flash loans, you will have to pay transaction fees whether the transaction was successful or not. Most flash loan providers require coding skills, and scammers take advantage of this requirement to steal people’s money. They do this by offering users a smart contract that has malware.

Flash loans in DAOs pose risks of market manipulation, smart contract vulnerabilities, and liquidity challenges. Malicious actors can exploit arbitrage opportunities, leading to financial losses. Smart contract vulnerabilities may be exacerbated due to rapid, complex transactions, and unexpected market changes during flash loans can expose the DAO to liquidity risks. Implementing stringent security measures, thorough risk assessments, and continuous monitoring is essential to mitigate these risks effectively.

2 Legal implications

Another risk of using flash loans in DAOs is that they can create legal uncertainties and liabilities for the users, developers, and regulators of the DAOs. Flash loans are a relatively new and unregulated phenomenon in the crypto space, and their legal status and implications are unclear and vary across jurisdictions. For example, some flash loan transactions may be considered as market manipulation, fraud, or breach of contract, depending on the context and the intention of the parties involved. Moreover, flash loans may raise questions about the enforceability, validity, and accountability of the smart contracts that facilitate them, as well as the rights and obligations of the lenders, borrowers, and intermediaries.

3 Ethical dilemmas

A third risk of using flash loans in DAOs is that they can create ethical dilemmas and conflicts of interest for the participants and stakeholders of the DAOs. Flash loans can be seen as a powerful tool that democratizes access to liquidity and enables innovation and experimentation in the decentralized finance (DeFi) ecosystem. However, they can also be seen as a dangerous weapon that undermines trust and fairness and enables exploitation and manipulation in the DeFi ecosystem. For example, some flash loan transactions may be considered as legitimate arbitrage or optimization strategies, while others may be considered as unethical or immoral hacks or attacks. Moreover, flash loans may challenge the values and principles of the DAOs, such as transparency, accountability, and decentralization.

4 Mitigation strategies

Despite the risks of using flash loans in DAOs, there are some possible mitigation strategies that can reduce the likelihood or impact of negative outcomes. For example, DAOs can implement robust security measures, such as audits, bug bounties, oracles, timelocks, or circuit breakers, to prevent or detect vulnerabilities or anomalies in their protocols or smart contracts. Moreover, DAOs can adopt clear and consistent governance rules, such as voting thresholds, quorums, or delegations, to ensure that the decisions and actions of the DAOs are aligned with the interests and preferences of the majority of the members. Furthermore, DAOs can foster a culture of trust and cooperation, such as by educating, incentivizing, or rewarding the users, developers, and regulators of the DAOs, to promote ethical and responsible behavior and discourage malicious or opportunistic behavior.

There are usually bugs seen in smart contracts and these bugs open the underlying protocol to operate in a nondeterministic fashion. Without being able to safely and reliably predict the outcome, smart contracts become unreliable/ unstable as the outputs can lie outside of planned parameters. The impact here is that the basis of profit in many flash loans is arbitrage which connects multiple platforms swapping or trading tokens. An error in one platform may ripple outward causing issues in another platform(s). There is also the concern of price manipulation where the prices may be artificially inflated or deflated thanks to exploits seen in SC based flash loans.
