Dune review

The wash-trading problem, solved by whoever wants to

NFT volume figures are unreliable because self-dealing between related wallets inflates them, and every provider makes a private decision about how to strip that out. Dune exposes the decoded marketplace events, so you can define your own filter, publish it, and let anyone re-run it against the same data. That is the difference between a number you were given and a number you can defend.

What it demands

SQL. Without it you are browsing dashboards built by others, whose filters you cannot check and whose authors may be confidently wrong. With it, you can answer questions nobody has published, which in this market is most of the interesting ones.

Coverage and cost

Decoded marketplace data across the major chains, with newly deployed contracts requiring decoding before they appear — so the freshest collections are the hardest to query. The free tier allows querying within published execution limits, and results export as CSV with the SQL portable to any equivalent dataset.

Who it suits

Analysts, funds and anyone publishing NFT market claims who would rather show their working than cite a dashboard.

A practical starting point

Fork an existing public dashboard for the collection you care about, read its filter, and change the parts you disagree with. That workflow teaches the data faster than any documentation and leaves you with a figure you can defend.
