The DeFi and Web3 trading platforms have grown at such a pace that the financial markets have never been more transparent, but at the same time, there are new problems that have arisen. Among the most common problems is wash trading and artificial volume, which are market irregularities that lead to confusion among traders. As the trading volumes continue to move towards the decentralized exchanges, cross-chain platforms, and the combined platforms, the monitoring systems are no longer able to keep up. This has led to a great interest in the use of artificial intelligence to identify the abnormal trading patterns.
This article will examine how AI wash trading and artificial volume detection work on Web3 exchanges.
Understanding Wash Trading and Artificial Volume in Web3
Wash trading is the act of trading an asset between the same parties to give the impression of strong trading activity. Artificial volume is a broad term that encompasses all trading activities that are intended to artificially boost figures such as liquidity, demand, and popularity.
In Web3, these activities are evolving due to the following factors:
Pseudonymous wallet addresses
Permissionless exchange access
Automated trading through smart contracts
Cross-chain asset transfers
Although blockchain data is publicly accessible, it is difficult to determine the intent of the transactions. This is where AI analytics comes in.
Why Detecting Artificial Volume is Important in Decentralized Markets
Having reliable trading data is essential for the efficiency of markets. Artificial volume can:
Deceive retail traders about liquidity
Affect price discovery algorithms
Erode confidence in decentralized exchanges
Influence token listings, rankings, and governance
From a macro perspective, unregulated market manipulation erodes confidence in Web3 infrastructure.
How AI Analyzes Blockchain Data at Scale
The AI systems used for Web3 monitoring involve large-scale data ingestion from on-chain and off-chain sources. Unlike traditional finance, blockchain data is immutable and timestamped, making it ideal for pattern analysis.
The key data sources that AI systems analyze include:
Transaction history data from multiple blockchains
Wallet interaction graphs
Order book and liquidity pool data
Smart contract execution data
Time-series price and volume data
Machine learning algorithms process this data in real-time to detect statistical anomalies that could indicate wash trading activity.
AI Techniques Used to Detect Wash Trading and Sybil Detection
AI does not use a single technique. Rather, it uses a combination of several analytical techniques to develop a probabilistic model.
The techniques commonly used include:
Anomaly detection
This technique identifies trading patterns that are statistically different from the norm.
Graph analysis
This technique maps wallet relationships to identify self-referential trading patterns.
Behavioral clustering
This technique groups wallets based on their trading behavior.
Temporal pattern recognition
This technique identifies repeated trades that occur at regular or irregular intervals.
Cross-market correlation analysis
This technique identifies volume surges that are not correlated with market activity.
Sybil Detection
This technique identifies situations where a single actor controls multiple wallet addresses to simulate independent market participants. In Web3, malicious traders often distribute wash trading activity across numerous pseudonymous wallets to avoid detection. AI-powered Sybil Detection uses wallet graph analysis, behavioral fingerprinting, transaction timing patterns, and funding source tracing to determine whether multiple addresses are likely coordinated by the same entity.
Step-by-Step: How AI Flags Suspicious Trading Activity
Below is a simplified overview of how AI systems typically operate in practice:
Collect real-time and historical blockchain data
Normalize transaction data across different protocols
Identify wallet clusters with repeated self-trading patterns
Compare volume behavior against liquidity and price movement
Assign risk scores to tokens, wallets, or exchanges
Continuously retrain models using new transaction data
This layered approach reduces false positives while maintaining scalability.
