The short answerBubblemaps turns a holder list into a graph where connected wallets cluster visually, so concentrated or coordinated ownership becomes obvious at a glance. Connection inference is heuristic — shared exchange funding can look like collusion — so read a cluster as a prompt to investigate.

What we liked, and what fell short
Liked- Immediate visual read on holder concentration and linked wallets
- Cheap with a usable free view
- Has exposed genuine insider clusters in live collections
Fell short- Shared funding paths sometimes reflect exchange routing, not collusion
- Coverage skews toward tokens over NFT collections
Why the marks landed where they did
The most valuable thirty seconds before buying into a collection or token is checking whether the top holders are actually one entity. A table of addresses will not tell you. A graph of funding relationships will.
How it works
Each holder is a bubble sized by holding, with lines connecting wallets that have funded or transacted with one another. Clusters of connected large holders — the standard pattern where insiders control most of the supply while presenting a distributed holder count — stand out immediately.
The false positive
Wallets funded from the same exchange withdrawal address appear linked while being unrelated users. Sophisticated actors also break linkage deliberately by routing through exchanges or mixers. A clean map is therefore weaker evidence than a dirty one, and a cluster warrants investigation rather than a conclusion.
Coverage and cost
Major EVM chains and Solana with a free view for well-known assets, and paid plans from around $20 a month for broader coverage and historical snapshots. Coverage skews toward tokens over NFT collections.
Who should use it
Anyone buying outside the top collections or tokens. It is the cheapest diligence available and the one most clearly linked to losses avoided.
FAQ
What does a Bubblemaps cluster mean?+
That the wallets have funded or transacted with each other. That often indicates one entity, and it can also reflect unrelated users funded from the same exchange address.
Is a clean map proof of fair distribution?+
No. Sophisticated actors break linkage deliberately by routing through exchanges, so an absence of clusters is weaker evidence than their presence.
What does Bubblemaps cost?+
A free view covers well-known assets, with paid plans from around $20 a month for broader coverage and history.
Does it cover NFT collections?+
Coverage skews toward tokens, with NFT support available on major chains but less comprehensive.
