NFT Fraud Detection — Spot Wash Trading and Fake Volume

Wash trading accounts for a significant portion of NFT marketplace volume. Fraudulent actors trade NFTs between their own wallets to inflate prices and create artificial demand. OnChainRisk detects these patterns automatically, protecting collectors, marketplaces, and investors from manipulated data.

How NFT Fraud Detection Works

1

Analyze a Wallet or Collection

Paste any wallet address or enter a collection contract. OnChainRisk scans the full transaction history for fraud patterns on Ethereum, Polygon, BSC, and Base.

2

Detect Wash Trading Patterns

The system identifies circular transactions, self-dealing between related wallets, and coordinated buying activity that inflates volume and floor prices.

3

Review the Evidence

See a detailed breakdown of flagged transactions with counterparty analysis, timing patterns, and fund flow graphs connecting suspicious wallets.

What OnChainRisk Detects in NFT Fraud Analysis

Circular transactions where the same NFT returns to the original seller through intermediary wallets
Self-dealing between wallets funded by the same source address
Coordinated buying rings that artificially inflate collection floor prices
Abnormal volume spikes with no organic buyer growth or social activity
Wallets with high sell-to-buy ratios indicating systematic manipulation
Cross-marketplace arbitrage patterns designed to create false price discovery signals

Why OnChainRisk for NFT Integrity

Multi-Chain Coverage

NFTs exist across Ethereum, Polygon, BSC, Base, Arbitrum, and more. OnChainRisk analyzes wallets on all these networks from a single interface — no need to switch tools per chain.

Graph-Based Analysis

Interactive fund flow graphs reveal wallet clusters and transaction loops that are invisible in raw transaction lists. Expand nodes to trace the full network of related addresses.

Protect Your Marketplace

Marketplace operators can use the API to flag suspicious collections and wallets before listing. Reduce fraud exposure and build trust with legitimate collectors.
