Bubble Maps in Crypto: How to Read One for a Solana Token

A crypto bubble map is a picture of who holds a token. Each bubble is a wallet, bigger bubbles hold more, and a line between two bubbles means funds have moved between those wallets. Lines are a lead to check, not proof.

One widely used tool for this is Bubblemaps. This guide shows how to read one for a Solana token like $CATE, using the tool’s own documentation, and where the picture can mislead you.

What a bubble map shows you

Start with the bubbles. Bubblemaps’ own guide says: “each bubble represents a current holder, and the larger the bubble, the more tokens they hold.” A holder here means a wallet address, the string of letters and numbers that identifies one account on the blockchain. One person can own many of them.

The map does not show everyone. For a typical token, the guide says it “shows the 250 top holders of this token as 250 bubbles.” A token with a hundred thousand holders is being shown through its largest few hundred, which is where concentration usually shows up.

Then the lines. The guide is precise about what a line means: “If two bubbles are linked, it means there has been an on-chain transfer between those holders.” On-chain means recorded on the blockchain itself, where anyone can look it up. In the current version of the tool, the guide adds, “these transfers can involve any token”, so a line can come from a transfer of a different token, not only the one you are studying.

Linked bubbles form groups. In the guide’s words, “when bubbles are linked and form clusters, it means they have sent funds to each other.” The company’s own explainer goes a step further and says it links wallets that are “likely controlled by the same entity”, which is the main reason people use it. Keep the word “likely” in mind. It matters later.

A bubble map is not a market heatmap

If you searched for a “crypto bubble map”, you may have landed on something else. Market heatmaps, which draw every coin as a tile or bubble sized by market value, turned up alongside Bubblemaps in a Google search for “crypto bubble map” on 2 November 2026. The two answer different questions.

CoinMarketCap describes its market chart as a heatmap “showing price rises and falls and relative asset size.” That is a market overview. It tells you nothing about who holds a token, which is the question this guide is about.

Holder maps and market heatmaps, based on each tool’s own description, checked 2 November 2026

	Holder bubble map	Market heatmap
Each shape is	One wallet holding a single token	One coin or token
Size means	How much of that token the wallet holds	The coin’s size in the market
Lines mean	Transfers between wallets	Usually no lines
Answers	Who holds this token, and are they connected?	What went up or down today?

Opening a map for a Solana token

Bubblemaps says its core features are “free to use”, and that Solana is one of the chains it supports. Its explainer gives the steps in one line: “select a chain, and paste any token contract address.”

The address you paste is the token’s own address, also called the mint or contract address. Paste the wrong one and you get a perfectly accurate map of the wrong token. That is a real risk with a name like $CATE, which shares its ticker with several other tokens. Our guide to what a contract address is explains how to find the right one, and which CateCoin is which lists the namesakes.

Before you read anything, check when the map was made. The guide says a map is “guaranteed to have been refreshed within the last six hours,” though “there may still be some delays, especially for newly launched tokens.” A fast-moving meme coin can change a lot in six hours, so check the time the map was last computed, which the guide says is shown at the top of the map.

Read a bubble map in four passes

A busy map is easier to read if you look for one thing at a time. Each of these four passes asks a single question, in order, and the sketch below shows what each one is looking for on the screen. Taking them one at a time keeps a crowded map readable.

Pass 1: unhide the pools. The guide says “some bubbles are hidden by default if they belong to contracts or exchanges.” A trading pool, the shared pot that lets people swap a token, is run by a program, which is Solana’s word for a contract. So if the largest holder you expect is a pool, look for it in the hidden list. Click the eye button next to it to show it. Our post on what the top 10 holders figure measures explains why pools inflate concentration numbers.

Pass 2: find the big loners. Look for large bubbles with no lines. Click one and the guide says a window shows “the % of the supply it holds.” A single wallet with a large share is a concentration question on its own, connected or not.

Pass 3: find the clusters. Now look for groups. Ten wallets each holding a small share look harmless one by one. Joined together, they can add up to a large share held by what may be one owner. The guide says that when a wallet is part of a cluster, its window also gives aggregated information about the cluster.

Pass 4: look at the spread. Finally, step back. Many small, unlinked bubbles suggest ownership is spread out among the top holders. A map dominated by a few clusters means it is not.

What a link does not prove

This is the easiest part to misread. A line proves one thing: at some point, value moved between those two wallets. It does not prove who owns them or why the money moved.

Bubblemaps’ own guide makes the point. Faced with two connected wallets, it says the key question is why, and offers three possible answers: “an employer paying an employee, a VC receiving tokens, or someone trying to cover their tracks.” Only the last one suggests someone is hiding something, though any of them can still mean ownership is concentrated. Two friends who once sent each other tokens would show up linked too.

The link can also come from a transfer that has nothing to do with this token, since the guide says links can involve any token. Click “All Tokens” to open the transfer filter, then choose only the token you care about. That one setting can turn a frightening cluster into a handful of unrelated wallets, or confirm it.

Some links are also missing. The guide says very busy addresses, such as exchange hot wallets, are labelled Supernodes, and “even if two super nodes are connected, they won’t show links on the map.” Two wallets that both bought through an exchange can look unrelated. A clean map is not a clean bill of health.

The explainer itself says the tool “works best when used alongside others”, and points to block explorers to check the underlying transactions. Treat a cluster as a question you take to a block explorer, not an answer.

What a bubble map found after $CATE’s launch

$CATE has its own example. On 6 August 2026, Bubblemaps published a write-up of $CATE’s launch, reporting that “25 wallets controlled 19% of supply” and, separately, that “29 wallets sold $660,000 at the same minute.” Those are Bubblemaps’ findings, as published, and we have not checked them independently.

We covered what that day means for the idea of a fair start in what a fair launch means, and we will not repeat it here. The useful lesson for this guide is the question Bubblemaps asked between those two findings: “How long will they hold?” A concentrated group of wallets is a question about the future, and a bubble map is how you spot that group before you have to find out.

A map from August describes August. Bubblemaps counted 74,863 holders in that write-up; our stats feed, which reads holder data from GeckoTerminal, counted 143,513 on 2 November 2026. The two may count holders differently, but either way, do not read the August finding as today’s picture. Current holder figures are on our stats page, and you can open today’s map yourself by pasting $CATE’s address, Ai66LHZG9MCzg1WKdawwqduVAXpNDUuV8M3uyq5ppump, with Solana selected.

Frequently asked questions about bubble maps

Where a bubble map fits in your own checks

A bubble map is one view of a token. It answers “are the big holders connected?” It does not tell you whether the token can be changed, whether the pool can be pulled, or whether the address is the right one.

For those, our guide to checking any Solana token yourself walks through the rest, and is $CATE safe applies the same checks to $CATE. Open the map, run the four passes, and take what you find to the other checks. That habit is worth more than any single picture.
