DeFi changes how we handle money – banks, payment processors, and almost all financial intermediaries we use today will become obsolete, practically, with DeFi. But this shifts the responsibility of securing our money to us and the platforms we entrust it to. You could argue that this was always the case, but DeFi takes it to a whole new level. We don’t have to go too far to see the consequences of this. The incessant hacks, attacks, and exploits on current DeFi protocols and platforms are sufficient evidence.
However, artificial intelligence (AI) could offer hope for handling this heavy responsibility. Thanks to the sheer power and efficiency of these new AI-based models, we have seen instances and potential ways that AI can be harnessed to make DeFi even safer.
This article explores how AI can be implemented in DeFi to make it safer and secure.
Understanding DeFi Security Challenges
The basic premise of DeFi is to eliminate intermediaries in financial transactions, which was previously impossible because of the limits of available technology. However, the decentralized nature of DeFi platforms introduces significant security risks which could be platform-borne or from the user themselves.
Software/Code Vulnerabilities
A good example of a sort of security risk are bugs or flaws in smart contracts, the backbone of DeFi operations, that hackers can exploit. For example, malicious actors exploited a flaw in The DAO’s smart contracts, resulting in the theft of millions of dollars’ worth of Ether in 2016. Also, Bancor, a DEX, lost $23.5 million when hackers exploited a vulnerability in its smart contracts in 2018.
Other forms of security risks that could be code-based are flash loan attacks, oracle manipulation, cross-chain vulnerabilities, and many more as we have seen with recent exploit cases.
DeFi relies heavily on liquidity pools, where users contribute funds to enable trading. These pools are vulnerable to impermanent loss, where the value of assets changes, and they can also be targeted by hackers to steal funds directly from the pools. We see this in front-running attacks. On the other hand, it could be the platform developers themselves that have malicious intents – Rug Pulls.
The complexity of DeFi platforms can lead to user mistakes, such as sending funds to incorrect addresses or interacting with malicious contracts. Users could also be susceptible to phishing scams and give out their details to malicious agents unknowingly.
How AI can make DeFi Secure and Safe
AI can be a powerful ally in securing DeFi platforms. It can be used to buffer various aspects of security and make the ecosystem more robust and trustworthy for both protocol providers and users.
On Protocols’ Part
From the standpoint of DeFi protocols and platform providers, AI is an indispensable tool for maintaining robust security measures and staying ahead of malicious agents.
Advanced Threat Detection and Prevention
AI-powered systems can monitor network traffic and transaction patterns in real-time, identifying anomalies that may indicate potential attacks. These systems analyze vast amounts of data, detecting threats before they materialize and triggering immediate responses to security breaches, thereby minimizing potential damage.
User authentication in DeFi platforms is strengthened through AI-driven biometric methods, such as facial recognition or fingerprint scanning. Behavioral analysis powered by AI can detect unusual account activity, adding an extra layer of security. You can also get multi-factor authentication systems that adapt to user patterns and potential threats which further enhance the overall security posture for individual users.
Fraud Detection and Prevention
AI significantly enhances fraud detection and prevention in DeFi platforms. By identifying suspicious transaction patterns, AI systems can flag potentially fraudulent activities for further investigation. Advanced authentication mechanisms powered by AI help prevent unauthorized access, while machine learning algorithms continuously learn from new fraud attempts to improve detection capabilities. This adaptive approach ensures that security measures evolve alongside emerging threats, keeping DeFi platforms one step ahead of potential attackers.
Smart Contract Optimization
AI can play a crucial role in smart contract security by automating the auditing process, reducing human error, and identifying vulnerabilities before deployment. It can also optimize gas usage and suggest improvements in smart contract design based on historical data and best practices.
Regulatory compliance is another area where AI proves invaluable for DeFi platforms. As the regulatory landscape continues to evolve, AI assists in staying compliant with changing requirements through automated policy updates. It enables more effective implementation of Know Your Customer (KYC) and Anti-Money Laundering (AML) procedures, crucial for maintaining the integrity of DeFi platforms. Additionally, AI-driven systems can generate comprehensive audit trails for regulatory reporting, streamlining the compliance process.
On Users’ Part
From the user perspective, AI technology offers significant benefits in terms of improved security and enhanced decision-making capabilities.
AI provides users with real-time market analysis and predictions, empowering them to make more informed investment decisions. Personalized risk assessments based on individual user profiles and market conditions offer tailored insights, while automated portfolio rebalancing suggestions help optimize returns and manage risk effectively.
Personalized Security Recommendations
AI also plays a crucial role in educating and protecting users through personalized security recommendations. By analyzing user activity and risk profiles, AI can offer tailored security advice and alert users to potential vulnerabilities in connected wallets or decentralized applications (dApps). This proactive approach helps users stay informed about best practices in DeFi security, reducing the risk of falling victim to scams or attacks.
Automated Security Operations
Automated security operations driven by AI benefit users by continuously monitoring account activity and alerting them to any unusual behavior. These systems can automatically execute stop-loss orders to protect investments during market volatility. Moreover, AI facilitates secure key management and recovery processes, addressing one of the most critical aspects of user security in the DeFi space.
Examples of How AI is Currently Used For DeFi Security
Chainlink
Chainlink provides decentralized oracles that deliver off-chain data to smart contracts, and AI plays a crucial role in enhancing the security of this process. AI algorithms aggregate and verify data from various sources, ensuring that only accurate and reliable information is fed into smart contracts.
By detecting and filtering out anomalous data points, AI helps prevent potential threats that could compromise the integrity of smart contract executions. This use of AI strengthens the security of decentralized applications that rely on Chainlink’s oracles, providing a robust and trustworthy data feed.
Chainalysis
Chainalysis specializes in blockchain analysis using AI to monitor transactions across diverse networks, enhancing DeFi security. AI algorithms detect transaction behavior patterns indicative of suspicious activities such as money laundering or terrorist financing. This capability enables Chainalysis to track illicit activities and flag transactions linked to criminal organizations.
For enhanced security, Chainalysis uses AI to assign risk scores to addresses and transactions based on historical data analysis, identifying risky behaviors like large fund transfers or interactions with high-risk entities. This AI-driven approach ensures robust monitoring and compliance with financial sector regulations.
