Yes, the basic web tool is free with no signup. Premium tier ($20/month) adds Cluster Score history, alerts, and bigger holder windows. Free is enough for casual use.

How does Bubble Maps detect clusters?

Graph analysis on on-chain transfer history. Wallets that transfer tokens between each other are connected. Tight clusters of transfers = likely same entity.

Can clusters be hidden?

Yes — sophisticated teams use intermediary wallets, OTC deals, or freshly-funded wallets to avoid obvious connections. Bubble Maps catches lazy insiders, not sophisticated ones. Combine with other tools.

Why does Coinbase wallet look like a huge cluster?

Centralized exchanges hold many user tokens in shared wallets. Their bubble is huge but represents real diverse users. Bubble Maps labels known exchange wallets so you don't misread this.

Does Bubble Maps support Solana?

Yes since 2024. Solana memecoin analysis is one of Bubble Maps' fastest-growing use cases.

How fresh is Bubble Maps data?

Most chains: 10-15 minute lag. Major chains (Ethereum, BNB, Polygon): often near-real-time. Newer chains: sometimes 1-2 hour lag for indexing.

What Cluster Score is concerning?

Below 40: healthy. 40-70: mixed signals, check other indicators. Above 70: heavy insider clustering, high dump risk. Above 85: walk away.

Can I use Bubble Maps for NFT collections?

Limited support — Bubble Maps is built for fungible tokens. For NFTs, use OpenSea analytics or Nansen NFT tools.

Bubble Maps Holder Analysis 2026

What does Bubble Maps actually show?

Open bubblemaps.io and paste any token's contract address. The tool visualizes the top 250 holders as bubbles. Bubble size = wallet's percentage of token supply. Position = arbitrary (forces sort it for clarity). Lines between bubbles = these two wallets have transferred tokens to each other.

The interesting insight is the lines. If wallets A, B, C, and D form a tightly-connected cluster, they're probably the same entity (or coordinated team) holding tokens through multiple addresses. For a project claiming '15,000 holders, decentralized', a few large connected clusters reveal the truth: 5-10 entities hold most of the supply.

Insider cluster patterns to watch for

Single dominant cluster (50%+ of supply): one entity controls the project. High dump risk.
10-20 wallets ringed around a central wallet: classic 'team distribution' to fake decentralization. They'll dump as a group.
Many small bubbles with no connections: healthy retail distribution. Best signal for legitimate project.
Bubbles connected to known centralized exchange wallets: at least some real retail traders are involved.
Bubbles connected to a known scammer (red label): walk away immediately.

Reading the Cluster Score (2025+)

Bubble Maps added an automated Cluster Score in 2025. It runs algorithmic analysis on the connection patterns and returns a 0-100 risk number. Lower is better. Under 30 is generally healthy distribution; above 70 is heavily clustered.

Note: Cluster Score is a heuristic. A 'good' score doesn't guarantee safety (teams can hide distribution off-chain via OTC). But a 'bad' score is reliable evidence of insider clustering — trust the high numbers.

Three real examples

USDC: Cluster Score 22. Heavy concentration in exchange hot wallets and Circle treasury (expected for stablecoin), but holder base is genuinely diverse. Healthy.

Random new memecoin from Telegram pump: Cluster Score 87. Three large clusters of 5-8 wallets each. Total cluster holdings: 71% of supply. Classic rug-prep — these wallets will dump on retail buyers.

Mid-cap altcoin with 6-month history: Cluster Score 51. Some clustering visible but team locked in vesting contract; remaining clusters look like funds/whales. Mixed signal — proceed with smaller position.

Pro tip — combine with DexScreener and GoPlus

Bubble Maps tells you about HOLDER concentration. To fully vet a token, combine with:

GoPlus (gopluslabs.io) — contract-level risk scan. Catches honeypot logic, hidden mint authority.
DexScreener — volume, liquidity, transaction count. Confirms market exists vs wash-traded.
Etherscan / Solscan — verify contract source code is published, check sniper wallet activity at launch.
Bubble Maps — final check on holder distribution.

All four together = 60 seconds. Skipping any one of them is asking to be drained.

Bubble Maps premium features

Free tier shows top 250 holders, basic cluster visualization. Premium ($20/month) adds: cluster scoring with historical trend, custom labels for known wallets, alerts on whale movements, and bigger holder window (500+ wallets).

For occasional retail use, free is enough. For full-time meme traders or fund analysts, premium pays for itself in one avoided rug.

Limits of Bubble Maps

The tool can be tricked or miss patterns:

Off-chain distribution (OTC deals between insiders) doesn't show on-chain. Clusters can be hidden.
Fresh wallets with no transaction history won't be flagged as suspicious even if they're insider-controlled.
Some chains have limited indexing — Solana memecoins flow so fast Bubble Maps can lag.
Cluster analysis only catches direct transfers. Indirect (A → B → C → D) might miss the link.

Workflow — adding Bubble Maps to your token-vetting routine

Spot a token on DexScreener or Twitter. Copy the contract address.
Run GoPlus scan first (60 seconds). Walk away if any critical flags.
Run Bubble Maps. Walk away if Cluster Score > 70 or visible insider cluster owns > 40%.
Check Honeypot.is for sell simulation. Walk away if honeypot detected.
If all three pass: small position, take profits aggressively at 2-5x gain.
