How to use Bubblemaps to check a memecoin (2026)

To use Bubblemaps, open the app at v2.bubblemaps.io, pick the chain, paste a token’s contract address and read the map: each bubble is a top holder, and bubbles with the same color are wallets that one entity likely controls. Bubblemaps is the free bubble map crypto traders use to find hidden team wallets and bundled launches before they buy. It is one tool in our list of the best rug checkers; this guide shows how to read it, which numbers are red flags, and how to buy only after the check.

Bubblemaps at a glance

What is Bubblemaps?

Bubblemaps is an on-chain analytics tool that turns a token’s holder list into a picture. Each bubble is a current holder, the bubble size is the amount it holds, and a line between two bubbles means there was a transfer between them, per the Bubblemaps wiki (opens in a new tab). That is why people search for it as “bubble map crypto”: the map replaces a long list of anonymous addresses.

The core app is free. Bubblemaps made V2 free for everyone, including Magic Nodes, Time Travel and real-time data. Holders of its BMT token get P&L computation, cross-chain analytics, AI models that interpret clusters and maps of the top 1,000 holders (Bubblemaps Premium (opens in a new tab)). You do not need an account for the core features (Bubblemaps beginner guide (opens in a new tab)).

The Bubblemaps API (opens in a new tab) lists 14 chains, among them Ethereum, Base, Solana, BNB Chain, Tron, TON, Arbitrum, HyperEVM and Robinhood Chain. Bubblemaps also sells its map as an embed and says that CoinGecko and DEX Screener (opens in a new tab) use it, so you may already have seen one on a token page.

How to use Bubblemaps step by step

These steps follow the official Bubblemaps wiki (opens in a new tab) and the beginner guide (opens in a new tab) on its blog. The full check takes a few minutes.

1. 1

   Open the app and pick the chain

   Go to bubblemaps.io and click Launch App, or open v2.bubblemaps.io. Choose the chain in the selector next to the search bar.
2. 2

   Paste the contract address

   Search by name only for well-known tokens. For a new memecoin, paste the full contract address: copy it from the coin’s page in your trading app or from DEX Screener, and check it against the project’s official X account.
3. 3

   Read the shape before you click

   A healthy map looks scattered: many bubbles of different sizes, few lines between the big ones, no color that takes over. A risky map looks like a solar system: one big same-color group with lines back to one source.
4. 4

   Click the biggest bubbles

   The panel shows the wallet’s share of supply, token amount, dollar value and its cluster totals. Labels such as “Deployer”, an exchange name or a liquidity pool tell you what the wallet is.
5. 5

   Add up each cluster in the Address List

   The ranked list on the right shows the top holders. Holders with the same color are one cluster, so add their shares: five wallets at 3% each are 15% in one set of hands.
6. 6

   Check bundles, the deployer and the history

   Look for wallets that bought together at launch and for tokens the deployer sent out. Then use Time Travel (click the price chart or the date picker) to compare the launch map with today.
7. 7

   Turn on Magic Nodes for hidden links

   Magic Nodes adds wallets that hold none of the token but connect holders, such as one address that paid gas for many of them. They appear with dotted borders.

Two settings matter on busy maps. Exchange and contract wallets are hidden by default; click the eye button to show them. The map is refreshed within the last six hours, and new tokens can lag, so check the “last computed” time at the top (Bubblemaps wiki (opens in a new tab)). For more holders, the Add addresses page (opens in a new tab) shows how to raise the map from 250 to 500 holders.

How to read clusters on a bubble map

A cluster is a group of wallets that Bubblemaps believes one person or group controls, because they sent funds to each other or acted in a coordinated way. Bubblemaps gives them the same color. The cluster total, not the biggest single bubble, is the number that matters.

Bubblemaps’ own guide to memecoin holders (opens in a new tab) gives these thresholds for one cluster and for bundled supply at launch:

Sources: Bubblemaps holder guide (opens in a new tab), Bubblemaps beginner guide (opens in a new tab).

The guide says these are not hard rules. A 25% cluster that is a team wallet with a public, locked vesting plan is not the same as 25% in anonymous wallets. Exchange wallets and the liquidity pool are also big, but they are not insider positions.

The Bubblemaps Score sums this up from 0 to 100. It reads the top 250 holders without exchanges, DEXs and contracts, and more or bigger clusters lower it. In the score examples (opens in a new tab), one cluster with 58.39% of supply scored 14.8, and an even spread with one 1.62% cluster scored 85.4. The score only counts what Bubblemaps detects, so read the map too.

Bubblemaps on Solana: pump.fun coins and bundles

Bubblemaps on Solana works the same way, but two things look different on a fresh memecoin.

• The pool at number one: on Solana memecoins, one liquidity pool wallet often holds 10–15% of supply as the top holder. That is normal; an unlabeled wallet with 20% or more and links to other top holders is not (beginner guide (opens in a new tab)).
• Bundles: in a bundled launch, one buyer uses many wallets in the first blocks, so the supply looks spread out. Bubblemaps says to check for bundles on any token under 48 hours old.
• Many cheap wallets: low fees make it cheap to run dozens of wallets. Bubblemaps says many Solana memecoin rugs involve deployers with 30 to 50 wallets (holder guide (opens in a new tab)).

A real case shows the pattern. On SHAR, a Solana memecoin, Bubblemaps found that 60% of the supply was bought at launch across more than 100 addresses. All of them sent their tokens to one wallet, which sold for $3.4 million, and the market cap fell 96.3% in two seconds (Decrypt report on SHAR (opens in a new tab)).

Time Nodes catch wallets that never touch each other directly. The Time Nodes page (opens in a new tab) shows more than 150 wallets funded from Binance in tight time windows. Each one sent SOL to a fresh wallet that bought BULLISH in its first 30 minutes. For the wider set of pump.fun checks, see is pump.fun safe.

Red flags on a bubble map

Walk away when a map shows two or more of these. They come from Bubblemaps’ rug pull guide (opens in a new tab) and holder guide.

1. One color takes over: one cluster holds more than 20–30% of supply, or the top 10 wallets share a color.
2. A star pattern: one central wallet with lines to many smaller ones, which points to one operator with many addresses.
3. A busy deployer: the dev wallet still holds a large share, or it sent tokens to a network of fresh wallets.
4. Bundled launch supply above 15%: those wallets bought cheaper than you and are likely to sell into later buyers.
5. A cluster that breaks up: a stable cluster starts to send tokens to fresh wallets, often a step before a sale.
6. More concentration over time: Time Travel shows the top holders hold more now than at launch while the price rose.

Bubblemaps has used these signals in public cases. On LIBRA, it reported that 82% of the supply was unlocked and sellable from the start (Cointelegraph report on LIBRA (opens in a new tab)). Its HAWK case study says insiders dumped 16% of the supply (Bubblemaps case studies (opens in a new tab)). When you buy into a pattern like this, you become exit liquidity.

What Bubblemaps cannot show

Bubblemaps says plainly that it is one layer of research, not the full check (rug pull guide (opens in a new tab)). Three gaps matter most:

• Contract backdoors: mint functions, transfer limits and hidden admin keys do not show on the map. On Solana, check that mint and freeze authority are revoked.
• Off-chain deals: paid promotions and fake partnerships leave no trace in the holder list.
• Liquidity locks that end: a token can look well spread out while its liquidity lock runs out in 30 days.

So run a contract checker such as RugCheck or Honeypot.is next to Bubblemaps. Our guide on how rug pulls work explains each scam type.

Check, then buy: the pump.fun app or BasedBot

Bubblemaps has its own Swap panel, but you get the best result when you check in Bubblemaps and then buy in a tool built for memecoins (Bubblemaps Swap (opens in a new tab)). Copy the contract address once, check it, and paste the same address in your trading app.

Best overall: the pump.fun app

The pump.fun app scores 4.7 in our pump.fun app review and is our best overall pick for memecoins. Many new Solana memecoins start on pump.fun, so you can often find the coin you mapped in the app’s search: paste the same contract address. Our pump.fun app tutorial covers the first deposit and the first buy.

With code lockein you pay a 0.40% app fee instead of 0.45% (pump.fun fees (opens in a new tab)). New app users who type the code before their first card deposit and trade on 5 days within 10 days can get up to $50 matched, while the budget lasts. The match is not available in the UK (Referral Rewards terms (opens in a new tab)). The full terms are on our pump.fun referral code page.

Best for pros: BasedBot

BasedBot scores 4.6 in our BasedBot review and is our pick for pros. Locke works with BasedBot; it is scored with the same methodology. Its checks sit where you buy: the token monitor shows taxes, and an Audit button asks for a contract analysis that can take up to 3 minutes (BasedBot Audit page (opens in a new tab)). That helps with the contract gap that Bubblemaps leaves, but it does not replace your own checks. Code START doubles the cashback to 10–50% of the 1% fee; see our BasedBot referral code page.

If you are new to crypto and want a simpler app, Fomo is our pick for beginners; see the Fomo review.

Mistakes to avoid

• Do not search new tokens by name. Copycat coins share names and tickers. Paste the contract address.
• Do not count the pool or exchanges as insiders. Check the label before you add a big bubble to a cluster.
• Do not trust the score alone. It counts only the clusters Bubblemaps detects, and a fresh map can be up to six hours old.
• Do not skip the contract check. A spread-out map does not show a mint function or a freeze authority.
• Do not check once and forget. Clusters break up and deployers sell later, so look again before you add to a position.

Bottom line

To use Bubblemaps, paste the contract address, read the shape, add up each same-color cluster and check bundles, the deployer and the history. One cluster above 30% or bundled supply above 30% is a reason to skip the coin. Then run a contract check and buy in the pump.fun app or BasedBot.
