What is wash trading?
Wash trading involves transactions by the same controller or coordinated parties that create a misleading impression of market activity. For NFTs, sales between commonly controlled wallets can generate volume without attracting new collectors. A plain wallet transfer without a sale is a different event.
Example
Suppose one person controls wallets A and B and sells the same NFT between them ten times for 1 ETH per sale. A report counting every sale records 10 ETH of volume. Ten independent buyers have not arrived. The controller may still pay network or marketplace fees; reported volume is not their profit.
How can it be spotted?
A seller funding a buyer wallet and an NFT repeatedly returning to its previous wallet are patterns worth investigating. A common funding source alone is not conclusive: exchanges, custody services and legitimate transfers can complicate attribution. Before comparing raw and filtered volume in Dune dashboards, read the filtering rules and coverage.
The 100 ETH comparison in our NFT market analysis shows how raw and filtered volume can lead to different assessments.
