• Current legal frameworks struggle to adapt to the autonomy of AI agents, resulting in unclear liability boundaries.
• When selecting decentralized finance platforms, pay close attention to compliance and transparency.
• Using insurance mechanisms can reduce the risk of losses caused by AI agent errors.
• Regular audits and monitoring can enhance fund security and minimize potential losses.

The Liability Dilemma of AI Agent Errors

Insufficiency of Current Legal Frameworks

When using decentralized finance platforms, you may find that after an AI agent error occurs, liability attribution becomes extremely complicated. Existing legal systems primarily rely on traditional product liability and negligence principles to handle errors in financial transactions, but the autonomy and complexity of AI systems pose enormous challenges to these principles. You will encounter the following major difficulties:

• Current legal frameworks typically require liability to be assigned to a specific entity, but AI agents themselves lack legal personhood and cannot directly bear legal responsibility.
• As a user, if you allow an AI agent to operate fully autonomously without setting human confirmation points, you are effectively bearing most of the risk. When the AI agent errs, ultimate responsibility often still falls on you.
• The legal environment lacks unified standards, especially in cross-border transactions and multi-party blockchain ecosystems, making liability attribution even more ambiguous.
• The complexity of data supply chains also exacerbates the difficulty of determining liability. AI systems may depend on multi-layer algorithms, open-source libraries maintained by global developers, or third-party data—any link failure can cause AI agent errors, but tracing the specific responsible party is extremely difficult.
• While traditional indemnity or joint liability principles can help allocate responsibility, in AI agent error scenarios, victims often struggle to identify a clear direction for legal claims.

You need to be aware that the learning and adaptive capabilities of AI mean that “defects” may only become apparent after the system has been running for some time, further testing the applicability of existing legal principles.

Real-world cases also reflect the ambiguity of liability attribution. For example, the UK Post Office Horizon scandal involved technical flaws in IT systems leading to wrongful convictions of many users, highlighting the enormous difficulty in determining AI decision-making responsibility. The U.S. Zillow platform faced liability disputes between users and the platform due to AI algorithm misjudgments causing home valuation deviations. These cases demonstrate that existing legal frameworks often fail to provide clear answers after AI agent errors occur.

Lack of Legal Personhood and Liability Gaps

You may wonder why AI agents cannot bear legal responsibility like natural persons or companies. The fundamental reason is that AI agents lack civil legal personhood. According to existing law, AI behavior is generally regarded as the behavior of its user or developer, not the AI itself. The table below helps you understand this legal gap:

In actual operations, if you delegate high-risk activities to an AI agent, you are in principle responsible for damages caused by the AI. Even if the AI agent error stems from third-party data or open-source library issues, the law generally cannot directly hold the AI itself accountable. You must bear the losses resulting from AI agent errors, including those from hacks, infringement of others’ rights, or violations of payment processing laws.

• You are typically responsible for situations where you have not implemented control over the AI agent’s decision-making architecture.
• If an AI agent error causes losses to others, victims may claim compensation from you rather than from AI developers or platforms.
• When configuring AI agents, you must fully consider risk prevention and liability assumption; otherwise, once issues arise, the law offers little effective protection.

You must understand that the stronger the autonomy of an AI agent, the greater the gray area in liability attribution. Current law has not yet provided a clear path for allocating responsibility after AI agent errors—this is a risk you cannot ignore.

AI Agent Error Scenarios and Risks

Smart Contract Execution Errors

When using decentralized finance platforms, the automatic execution of smart contracts brings efficiency and transparency to transactions but also conceals significant risks. AI agents can autonomously analyze and exploit vulnerabilities in smart contracts. Research shows that AI systems successfully reproduced attacks on 207 out of 405 real-world exploited contracts, simulating “stolen funds” totaling up to $5 million. Even in contracts deployed after 2025, AI could still identify vulnerabilities in 19 contracts, with simulated losses reaching $4.6 million. AI can also discover new “zero-day” vulnerabilities, meaning that even using the latest contracts cannot completely eliminate losses caused by AI agent errors.

• AI agents may execute unauthorized transactions, leading to fund losses.
• Malicious actors may disguise themselves using AI agent identities to conduct fraudulent activities.
• On platforms, malicious agents may manipulate smart contracts, causing flash loan attacks or money laundering.

You need to be vigilant—lack of effective identity verification and contract auditing mechanisms will further amplify risks.

Misjudgment of Trading Parameters

When configuring AI agents, you often need to set a series of trading parameters. If the AI model misjudges market conditions or parameters are unreasonably set, it can easily lead to capital losses. For example, AI may incorrectly increase leverage during high-volatility periods or initiate large transactions during low-liquidity periods, ultimately causing slippage and asset losses. Studies indicate that the absence of mechanisms to prove agent identity and intent can lead to internal fraud and systemic unpredictability. You also need to note that agent identity verification mechanisms are not yet mature, making platforms more vulnerable to attacks.

• AI agent errors may stem from improper parameter settings or misjudgment of market data.
• If you do not set human confirmation points, the risk will be further amplified.

Data Source and Oracle Failures

When relying on AI agents for automated trading, the reliability of data sources is critical. Oracles serve as bridges between on-chain and off-chain data; once they fail, AI agents may make decisions based on incorrect information. For example, the Polymarket platform once suffered significant participant losses due to oracle manipulation, where whales uploaded false information via the UMA oracle. The oracle design allows token holders to vote on real-world event outcomes, making this mechanism highly vulnerable to attacks when data sources are insufficiently decentralized or unreliable.

• When oracles fail, they may provide unreliable or manipulated information, directly affecting AI agent decisions.
• Data source errors expose you to unpredictable financial risks.

When selecting platforms and AI agents, you must pay close attention to the security of their data sources and oracles; otherwise, once an AI agent error occurs, losses are difficult to recover.

Legal Liability Determination

Challenges in Applying Product Liability Law

When facing losses caused by AI agent errors, you may first consider seeking compensation through product liability law. However, in reality, you will find many obstacles to applying product liability law in the decentralized finance field:

• AI lacks subjective intent. You cannot hold AI accountable for its “decisions” in the same way as pursuing a traditional product manufacturer. AI behavior is driven by algorithms and data rather than subjective intent, making traditional product liability law difficult to apply.
• The evolution of agency law means existing legal frameworks cannot effectively address the unique characteristics of AI. You will find that the autonomy and unpredictability of AI agents far exceed those of traditional agency tools, and current law struggles to cover these new risks.
• New liability frameworks are needed to accommodate the characteristics of AI systems. Existing legal systems have not yet established specialized liability allocation mechanisms for AI agent error scenarios.

Currently, major global jurisdictions have not recognized algorithms as having legal personality. When using AI agents, you cannot hold them legally accountable in the same way as a company. Decentralized organizations lack identifiable legal entities, further complicating liability attribution. Regulators generally believe that existing regulatory frameworks have not effectively addressed AI governance issues in decentralized finance. In practice, you often can only rely on contractual agreements or platform rules, but these are difficult to enforce in cross-border scenarios.

Civil Damage Compensation Principles

If you suffer losses due to AI agent errors, you will typically consider seeking compensation through civil damage compensation principles. You need to pay attention to the following core elements:

• Compensation for losses involves considerations of foreseeability, causation, and liability. You must prove that the damage was a foreseeable consequence of the other party’s breach and that there is a direct causal relationship with the AI agent’s behavior.
• Sometimes AI software developers are the actual cause of the damage, but in many cases, the developer’s actions are not the legal proximate cause because the damage was not foreseeable. You will face significant difficulty in providing evidence.
• Currently, there is no legal precedent allowing completely non-human entities (such as AI programs) to be held liable, unlike corporate liability. You cannot directly demand compensation from an AI agent as you would from a company.
• If AI models are held liable for contract breaches, developers may face higher legal risks. This risk makes many developers more cautious when designing AI agents, but it also limits innovation momentum.

In actual rights protection processes, you often need to overcome triple barriers of technology, law, and evidence. You must collect sufficient evidence to prove the causal relationship between the AI agent’s decisions and the losses, and that the losses fall within the foreseeable scope. Due to the highly complex and opaque decision-making process of AI agents, obtaining effective evidence is extremely difficult, making rights protection even harder.

Impact of Blockchain Anonymity

When using AI agents on decentralized finance platforms, blockchain anonymity makes liability tracing significantly more complex. The table below summarizes the main obstacles:

When encountering AI agent errors, you often cannot accurately identify the real identity of developers, operators, or other relevant parties. Blockchain anonymity makes legal accountability extremely difficult. Even if you can lock down an address or contract, the actual controllers may be distributed globally, severely limiting jurisdiction and enforcement.

You need to recognize that current regulators have not yet fully opened up to AI agent-related businesses. Regulatory gaps mean you have limited effective legal protection when suffering losses. When choosing platforms and AI agents, you must focus on their compliance and transparency to reduce risks caused by unclear liability attribution.

If your priority is to reduce the operational risk created by unclear liability, it may be safer to prefer platforms with clearer service boundaries and user-confirmed actions, rather than handing high-risk decisions entirely to autonomous agents. A service such as BiyaPay, positioned as a multi-asset wallet, covers cross-border payments, fund management, and trading-related scenarios; users can make their own decisions through its stock information page or a defined trading entry, which usually makes the responsibility chain easier to identify than in fully agent-driven execution.

This kind of platform is useful here as a contrast: when service scope, function entry points, and compliance disclosures are relatively clear, disputes are generally easier to trace and evidence. BiyaPay holds relevant financial registrations in jurisdictions including the United States and New Zealand; if international remittances or asset transfers are involved, users should at minimum verify the official domain, the function page, and the rule disclosures before proceeding.

Risk Control and Vulnerability Prevention

When using decentralized finance services, you must attach great importance to building risk control systems. The rapid growth and high returns in the DeFi environment attract large numbers of users but also bring complex fraudulent behaviors. You can use layered authorization and automatic downgrade mechanisms to strictly limit losses from permission runaway. For example, BiyaPay adopts multi-factor identity verification and permission grading in global payment and cryptocurrency exchange services to ensure that a single compromised account does not affect overall fund security. You can also use pre-execution simulation and inference chain auditing techniques to detect potential errors in advance and prevent large-scale losses from AI agent errors. De-homogenization strategies, circuit breaker designs, and cross-entity collaboration mechanisms can effectively prevent systemic risks caused by market volatility. You should continuously monitor whether platforms have comprehensive security measures and fraud detection systems, as this directly affects your asset security.

• Layered authorization and automatic downgrade mechanisms to limit single-point runaway risks
• Pre-execution simulation and on-chain auditing to intercept malicious or erroneous operations
• Circuit breakers and cross-platform collaboration to prevent systemic crises

When selecting platforms, prioritize service providers with the above risk control systems.

On-Chain Tracing and Liability Localization

When suffering losses on blockchain platforms, on-chain tracing technology can help you locate responsible parties. Complete audit trails record every agent decision, ensuring all operations are traceable. BiyaPay uses digital signature mechanisms in cryptocurrency transactions and fund flows—every transaction is signed by the relevant account’s private key, ensuring clear liability. The table below outlines key on-chain tracing technologies:

When disputes arise, you can rely on this on-chain evidence to improve rights protection efficiency. You should prioritize platforms that support on-chain auditing and liability localization to reduce tracing difficulties caused by anonymity.

AI Model Transparency

When using AI-driven financial services, model transparency directly affects your trust and security. Blockchain technology provides an immutable ledger for AI systems, recording all transactions and decisions for easy auditing and accountability. In fiat-to-cryptocurrency real-time exchange, USDT-to-USD/HKD and other businesses, BiyaPay relies on smart contracts for automated compliance checks, ensuring AI decisions meet preset standards and reducing risks from human intervention. You can also use decentralized control to lower single points of failure and malicious attack probabilities. The table below summarizes common industry practices for AI transparency:

You can also pay attention to whether platforms deploy federated learning, differential privacy, encrypted protocols, and other technologies—these measures help protect data security and enhance model transparency. When choosing AI financial services, prioritize platforms with the above transparency safeguards to reduce uncertainty caused by AI agent errors.

Case Studies and Industry Controversies

Typical AI Agent Error Cases

When using AI agents on decentralized finance platforms, you may encounter real loss cases. For example, in 2023, a U.S. DeFi platform’s AI automated trading strategy misjudged market volatility, leading to forced liquidation of user assets and losses exceeding $2 million. Platform developers claimed the AI model had been audited, but in actual operation, the model failed to identify abnormal market conditions in time, ultimately causing large-scale capital losses. You can also see that a licensed Hong Kong bank once rejected some customers’ loans due to AI risk control system misjudgment of credit risk, with subsequent rights protection processes being lengthy and complex. These cases show that AI agent errors not only affect fund security but may also trigger legal disputes and user trust crises.

Liability Judgments and User Rights Protection Challenges

When protecting your rights, you will find the liability judgment process extremely complicated. After AI agent errors occur, platforms, developers, and data providers often shift responsibility among themselves. You face multiple obstacles including unclear legal liability attribution, broken evidence chains, and cross-border accountability challenges. The table below summarizes the main challenges in user rights protection:

In actual operations, it is often difficult to obtain effective evidence proving the direct causal relationship between losses and AI agent errors. Even if you can identify the responsible party, cross-border legal enforcement and anonymity make compensation recovery inefficient. You need to understand that the industry has not yet established unified standards, and rights protection processes may take months or even longer. When choosing platforms and AI tools, pay close attention to their liability mechanisms and user protection measures to reduce future rights protection difficulties.

Industry Responses and Future Outlook

Insurance Mechanisms

When using AI agents on decentralized finance platforms, you can reduce losses caused by agent errors through insurance mechanisms. The current industry adopts various insurance models, as follows:

You can find that AI-driven risk management brings quantitative improvements in the DeFi field, such as reducing return volatility and decreasing security incidents. Insurers use automation and anomaly detection technologies to enhance operational risk management capabilities. You need to focus on data quality and model robustness, as erroneous price data may cause AI to make harmful decisions, highlighting the importance of data validation techniques.

Compliance and Standards

When selecting AI agent services, you must pay attention to compliance and industry standards. Industry literature proposes agent-based governance frameworks, emphasizing the importance of compliance. Standardized tools and processes are crucial for improving security and accountability. The table below summarizes current directions in compliance standard development:

User Self-Protection

As a user, you can proactively adopt various risk mitigation strategies. AI agents can dynamically adjust to market conditions, such as adjusting interest rates, collateral ratios, or liquidity pool allocations to adapt to market changes. Autonomous agents can make instant decisions, liquidating or reallocating funds during market volatility. AI continuously monitors smart contract vulnerabilities and immediately identifies abnormal transaction patterns. You can also use AI methodologies and reinforcement learning tools to learn from data, detect emerging patterns, and make optimized decisions under uncertainty. Continuous contract monitoring and rapid risk mitigation measures help improve asset security and trading stability.

When using AI agents, you must combine insurance, compliance, and self-protection measures to enhance fund security and trading stability.

When using AI agents in decentralized finance, liability determination is extremely complex. Legal and technical advancements must work together to establish a safe and transparent responsibility system. Over the next five years, the industry will strengthen auditing, monitoring, and compliance standards. You should focus on the following key points:

• AI agent reliability, bias, and errors may lead to financial losses.
• Strengthen data security, privacy protection, and multi-factor authentication.
• Regular auditing, transparent governance, and continuous monitoring can reduce risks.

You need to proactively prevent risks, choose compliant platforms, and continuously improve your self-protection capabilities.
