How this service works

“Before I buy into this NFT project, can you check whether the contract 0xED5AF388653567Af2F388E6224dC7C4b3241C544 on Ethereum has any wash trading going on — scan the last 30 days?”
NFT marketplace integrity audit
“I'm reviewing a collection for listing on our marketplace — run a wash trade scan on contract 0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB on Ethereum across the past 7 days and flag any circular trading patterns.”
Specific token manipulation check
