AI-powered smart contracts are gaining traction for their ability to process real-time data, detect security risks, and automatically update terms based on dynamic conditions. These contracts are increasingly used for applications like fraud detection, auditing, and predictive analytics.
For example, Ocean Protocol uses AI in its decentralized data marketplace to reduce disputes and improve transaction efficiency, while JP Morgan’s Onyx platform uses blockchain-based smart contracts to speed up payments and assess risks in real time.
Partnerships and implementations are actively shaping the future of AI-based smart contracts. Companies like Fetch.ai and Chainalysis are blending AI with blockchain to automate trading, portfolio management, and fraud detection. Major financial institutions, including Goldman Sachs and JP Morgan, are adopting these AI-driven solutions for securities settlement and risk management, demonstrating their effectiveness in complex financial environments.
The Evolution of Smart Contracts
Traditional smart contracts are self-executing programs on a blockchain that follow predefined, static rules. They use simple “if-then” logic, like “If Party A sends X cryptocurrency, then release the digital asset to Party B.” While effective for basic transactions, they cannot adapt to changing conditions or process complex, real-world data.
AI-Based Smart Contracts (Adaptive, Intelligent Logic)
AI-based smart contracts enhance traditional smart contracts by incorporating machine learning and artificial intelligence. These contracts can:
- Analyze real-time data (e.g., market trends, IoT inputs).
- Make dynamic decisions (e.g., adjusting loan terms based on real-time credit risk).
- Learn from past interactions (e.g., fraud detection models that improve over time).
The Move from Static Automation to Cognitive Automation
The evolution from rule-based smart contracts to AI-driven contracts is a leap from static automation to cognitive automation. AI contracts do more than execute predefined actions, they:
- Interpret unstructured data (e.g., legal documents, social media sentiment).
- Predict outcomes (e.g., forecasting liquidation risks in decentralized finance).
- Self-optimize (e.g., improving supply chain logistics dynamically).
Key Characteristics of AI-Based Smart Contracts
- Dynamic Logic Instead of Static Execution: AI contracts adjust in real time, like rebalancing portfolios if ETH drops by 10%, unlike static traditional contracts that follow fixed rules.
- AI Models Process Complex Data and Trigger Actions: AI contracts use NLP to analyze legal documents and computer vision to verify events, triggering actions based on detailed data.
- Interaction with Real-World Events & Continuous Learning: AI contracts integrate with oracles for off-chain data and use reinforcement learning to optimize decisions, such as adjusting prices in real time.
Types of AI-Based Smart Contracts

4. Competitive Edge
AI-based smart contracts provide businesses with a competitive edge by adapting in real time to market changes. They analyze data and trends to optimize contract performance, giving early adopters an advantage.
How Do AI Smart Contracts Work in a Blockchain Platform?
AI-based smart contracts combine blockchain’s secure, transparent logic with AI’s decision-making power. While AI handles complex tasks off-chain, the results are verified and stored on-chain through secure communication layers. This hybrid system ensures that smart contracts can adapt while maintaining reliability and transparency.
1. How Is the “AI” Component Implemented?
AI models, especially machine learning, work in a probabilistic way, meaning their outputs can vary. But blockchains like Ethereum need deterministic results, where every node has to agree on the outcome. This mismatch makes running AI directly on-chain tricky, as AI’s variability clashes with blockchain’s need for consistent results.
Why AI Models Are Mostly Off-Chain
Running complex AI models on-chain is not practical for several reasons:
- Gas costs: AI computations are often resource-intensive, making them expensive to execute on-chain.
- Computational limits: Blockchain platforms are not designed to handle the large-scale processing required for many machine learning tasks.
Solution: Typically, AI runs off-chain in a cloud or edge environment. The results from these AI models are then brought onto the blockchain for validation and execution. This ensures efficiency while maintaining the integrity of the blockchain.
Proof-of-Inference & Zero-Knowledge Techniques
To validate AI’s outputs without executing the full model on-chain, two cryptographic techniques are used:
- Proof-of-Inference (PoI): Provides a cryptographic proof that an AI model executed correctly and produced accurate results (e.g., Giza, Modulus Labs).
- Zero-Knowledge Proofs (ZKPs): These enable the blockchain to verify that an AI decision was made correctly without exposing sensitive input data.
Example: In decentralized finance, an AI model may assess the creditworthiness of a borrower off-chain. The result, confirmed by a ZK-proof, is then stored on-chain, verifying the decision without revealing personal data.
2. The Role of Decentralized Oracle Networks
Oracles act as a bridge between off-chain data and the blockchain. They are essential for feeding real-world information into AI systems and transmitting the outputs back to the blockchain.
How Oracles Fetch Off-Chain Data Securely
- Input: Oracles gather real-world data (e.g., stock prices, weather forecasts) and provide it to AI models for processing.
- Output: After AI has processed the data, the oracles relay the results to the smart contract.
Oracles aggregate data from various sources to ensure that the information is accurate and resistant to manipulation. They can support multiple AI/ML computations, providing a secure and trustworthy data stream for decentralized applications.
Leading Oracle Solutions:
- Chainlink: Offers robust support for AI/ML computations.
- API3: Provides decentralized APIs for direct data feeds.
- Band Protocol & Witnet: Facilitate cross-chain compatibility.
Example: In a decentralized insurance platform, Chainlink oracles fetch real-time weather data, allowing smart contracts to trigger payouts in case of natural disasters like floods.
3. Auditing Dynamic Logic for Security and Fairness
AI models evolve over time as they are trained on new data, which presents challenges in ensuring fairness, transparency, and security.
Why Traditional Static Audits Aren’t Enough
AI models are dynamic, which means their behavior can change as they learn or are updated. This introduces risks such as:
- Bias: The model may unintentionally favor certain groups.
- Adversarial attacks: Malicious actors could manipulate the model’s inputs or outputs.
- Unpredictability: AI may exhibit behaviors that weren’t anticipated by its developers.
Key Auditing Approaches
| Auditing Technique | Description |
| Explainable AI (XAI) | Uses techniques like SHAP (Shapley Additive Explanations) to make AI’s decision-making process interpretable, helping auditors understand why a model made a particular decision. |
| Model Versioning | Tracks changes made to the AI model over time, ensuring that updates or adjustments don’t lead to unintended consequences or regressions. |
| Behavior Snapshots | Records AI outputs at various stages, creating a trail of decision-making that can be reviewed for auditing purposes. |
| ZKPs for Verification | Uses Zero-Knowledge Proofs to prove that the AI model executed correctly without exposing sensitive training data or inputs. |
Example: A smart contract for credit scoring may need to be audited for fairness, ensuring the AI model doesn’t inadvertently discriminate against certain groups.
4. The Hybrid Architecture
AI-based smart contracts use a hybrid architecture, combining on-chain and off-chain components.
| Component | Description |
| On-Chain Logic: Immutable Contract Code | – Core logic (e.g., fund transfers, asset ownership) is encoded in smart contracts.- Once deployed, these contracts are immutable, ensuring reliability and transparency. |
| Off-Chain AI: External ML Systems | – Complex AI tasks like NLP or fraud detection are handled off-chain.- AI systems provide insights that blockchain alone can’t compute. |
| Oracle Bridge: Secure Communication Layer | – Oracles ensure secure, tamper-proof communication between off-chain AI and the blockchain.- They relay AI results back to the smart contract. |
| Optional: Multi-Agent Architecture | – Multiple AI agents may collaborate (e.g., one for risk assessment, another for pricing).- This enhances system flexibility and efficiency. |
5. Legal and Ethical Safeguards
AI-based smart contracts must address legal and ethical considerations to ensure fairness, transparency, and compliance.
- GDPR & Right to Be Forgotten: AI contracts must allow users to request the deletion of their personal data to comply with GDPR.
- Anti-Bias Models: AI models must be free from discrimination, using tools like IBM’s AI Fairness 360 to check and mitigate bias.
- Human-in-the-Loop Controls: Critical decisions should have human oversight to ensure automated actions are reviewed before final execution.
- Emergency Overrides & Arbitration: Smart contracts should include kill switches and rely on decentralized courts like Kleros for dispute resolution.

How to Implement AI Smart Contracts on a Blockchain Platform?
We help businesses create AI-based smart contracts on blockchain platforms to improve their operations and bring automation to the next level. By blending AI with the reliability and security of blockchain, we deliver solutions that streamline processes, enhance security, and provide real-time adaptability. Here’s a straightforward look at how we develop these smart contracts for our clients:
1. Identify Business Logic
We begin by fully understanding our client’s business goals and legal requirements. From there, we help translate these goals into digital terms that smart contracts can understand. We also pinpoint where AI can add value, such as automating risk assessments or detecting fraud, ensuring the contract reflects both the business logic and legal compliance.
2. Choose Blockchain Platform
We then select the best blockchain platform based on the project’s needs. Whether it’s Ethereum for its well-established ecosystem or a platform like Solana for scalability, we consider factors like computational costs and available developer tools. This step ensures the platform we choose supports both blockchain and AI functionality effectively.
3. Design Smart Contract & AI Architecture
With a clear understanding of the requirements, we design the smart contract and AI architecture. We balance static contract logic with dynamic AI components. Whether the AI runs off-chain or on-chain, we decide the best setup based on performance and cost. We also build in fail-safes and manual override options to ensure the contract can handle unexpected situations.
4. Train and Integrate AI Models
Next, we focus on training AI models using either data the client provides or on-chain data. These models might include things like fraud detection or personalized risk scoring. We prioritize transparency in these models, ensuring clients can easily track and verify the decisions AI makes, building trust and accountability.
5. Set Up Oracles & Bridge Mechanisms
We then set up oracles to ensure the smart contract receives accurate, real-time external data. These oracles act as bridges, bringing off-chain data into the contract. We configure them based on the types of data needed and ensure they are validated correctly, so the AI makes decisions based on the most accurate information.
6. Test, Audit, and Deploy
Before deployment, we rigorously test the contract and AI system, running simulations to identify potential issues. We audit both the contract’s security and the AI’s fairness to ensure they meet industry standards. After testing, we deploy the system gradually, monitoring it in real-time to ensure everything is working as expected and make any necessary adjustments.
Key Challenges of Implementing AI-Based Smart Contracts
Over the years, we’ve worked closely with clients to implement AI-powered smart contracts, giving us insight into the typical challenges businesses face. Here’s how we address these challenges to ensure success.
1. Gas and Compute Limitations
On-chain AI execution can be costly due to the computational power needed for complex machine learning models, driving up gas fees. Additionally, blockchain requires deterministic outputs, but AI models often produce probabilistic results.
Solutions
- Off-Chain Computation: We run AI models on cloud or edge servers and only submit verified results on-chain. This keeps the costs low while ensuring data integrity.
- Layer-2 Scaling Solutions: By using platforms like Polygon or Arbitrum, we reduce transaction costs and use zk-Rollups for privacy-preserving inferences.
2. AI Bias and Decision Transparency
AI models can sometimes make decisions that are difficult to explain, and biased training data can lead to unfair outcomes. For example, a credit-scoring model might unintentionally discriminate based on race or gender.
Solutions
- Model Interpretability Tools: Tools like SHAP and LIME help make AI models more understandable, ensuring that decisions can be audited and explained.
- Bias Testing: Before deployment, we use tools like IBM’s AI Fairness 360 and Google’s What-If Tool to identify and mitigate bias, while also using diverse datasets during training.
3. Oracle Manipulation or Data Poisoning
Oracles are essential for bringing off-chain data to the blockchain, but they are vulnerable to manipulation or data poisoning. Relying on a single oracle can create a single point of failure.
Solutions
- Decentralized Oracle Networks (DONs): We use robust decentralized oracles like Chainlink, API3, or Band Protocol to ensure data integrity. These networks cross-validate data from multiple sources to eliminate manipulation risks.
- Data Redundancy & Consensus Validation: By aggregating data from several independent sources and using threshold signatures (e.g., requiring a majority of oracles to agree), we ensure that data fed into the contract is accurate.
4. Legal Ambiguity and Compliance
Legal concerns arise, especially with AI contracts making decisions that could have significant consequences. Regulatory issues, such as the “right to be forgotten” under GDPR, can conflict with blockchain’s immutability.
Solutions
- Fallback Clauses & Human Oversight: We implement override mechanisms such as multisig keys and require human arbitration for high-stakes decisions, ensuring that no automated decision is final without oversight.
- Work with Blockchain Legal Experts: We collaborate with legal professionals to ensure smart contracts are compliant with regulations, including GDPR, and use off-chain storage solutions for sensitive data.

Use Case: AI-Based Smart Contract for DeFi Lending
A DeFi lending platform reached out to us with a tough challenge: their fixed loan-to-value ratios were either causing too many liquidations or leaving loans under-collateralized. They needed a solution to adjust risk in real-time while keeping things transparent. We built an AI-powered system that dynamically adjusts LTV ratios, ensuring both fairness and stability.
The Solution: AI-Based Dynamic Lending Contracts
We developed an AI-powered smart contract system that solved these problems by:
- Automatically adjusting loan terms based on real-time risk factors.
- Reducing unnecessary liquidations while safeguarding lenders.
- Ensuring full transparency and auditability of AI decisions.
Solution Architecture
| Component | Technology Used | Function |
| Core Smart Contract | Solidity (Ethereum) | Handles collateral locking, repayments, and liquidations. |
| Risk Assessment AI | PyTorch + SHAP | Analyzes borrower wallet history and market volatility. |
| Data Feeds | Chainlink Oracles | Pulls real-time asset prices and volatility indices. |
| Execution Layer | Polygon L2 | Provides fast and low-cost margin calls. |
| Explainability | zkML (EZKL) | Verifies AI decisions without exposing user data. |
How It Works in Practice
Loan Application & Risk Scoring
When a borrower connects their wallet, our AI assesses their historical repayment behavior, portfolio diversification, and current market conditions through Chainlink. Based on this, a dynamic loan-to-value (LTV) ratio is assigned—like 60% for low-risk scenarios or 45% for more volatile markets. This ensures the loan terms adjust to the borrower’s unique situation.
Real-Time Monitoring
Every 6 hours, the AI checks key factors like collateral value (using Chainlink price feeds), wallet activity (e.g., large withdrawals), and market volatility (e.g., BTC/ETH price swings). If the risk score drops, the AI automatically adjusts the LTV or triggers a margin call. This ensures the system responds quickly to changing conditions, protecting both borrowers and lenders
Transparent Liquidations
Before liquidation, the AI generates a SHAP report to explain the risk factors behind the decision. A zk-proof ensures the AI’s actions were fair and transparent. If needed, the borrower can either add collateral within a 12-hour grace period or appeal the decision to the DAO.
Results Achieved
- 70% fewer “unfair” liquidations compared to traditional fixed LTV systems.
- 20% more loans approved thanks to a personalized risk assessment approach.
- Full regulatory compliance with explainable AI decision trails, ensuring transparency and trust.
