Working out who actually holds a collection — and what else those wallets do — used to require enterprise tooling. Arkham made it a free web app, and for NFT research it is fast and effective.
What it does for NFT analysis
Groups addresses into entities, shows a wallet's full portfolio across tokens and NFTs, traces where an asset came from and where funds went afterwards. For evaluating whether a collection's holders are independent or one operator, it complements Bubblemaps' visual approach with entity attribution.
The attribution caveat
Labels are probabilistic, occasionally wrong, and there is no meaningful process for a subject to contest one. Acting on an attribution — publicly or financially — without independent verification is a mistake the interface's confidence encourages.
The business model
Arkham runs an intel exchange where users post bounties for identifying specific wallets and are paid for supplying that information. It is legal, it is disclosed, and it means using the product participates in a marketplace for individual deanonymisation. Users should decide about that consciously.
Who should use it
Researchers, journalists and traders tracing NFT flows, using the free tier, with attributions verified before being relied on.
