RugCheck vs Solsniffer vs Bubblemaps: What Each Measures
RugCheck, Solsniffer, TokenSniffer, Bubblemaps and DexScreener compared: what each one measures, what scores really mean, and the shared blind spot.
Paste a Solana mint address, the token's unique ID on the chain, into RugCheck and you get a verdict in about ten seconds. Solsniffer hands you one too, and so does TokenSniffer. The verdicts do not always agree, which pushes people toward the wrong question: which scanner is right? They measure different things. The real mistake is trusting any of them without knowing what was measured.
This comparison covers RugCheck, Solsniffer, TokenSniffer, Bubblemaps and DexScreener as they stand in July 2026. All five are real, useful products, and nothing below trashes them. There are no affiliate links on this page and nobody paid to appear. We build free Solana tools that cover an adjacent gap, so we have a stake in this topic; we would rather say that plainly than pretend to be neutral. None of this is investment advice.
What do token safety scanners actually do?
Token safety scanners automatically read a token's on-chain settings, hunt for configurations that have burned buyers before, and compress the findings into a summary or a score. That compression is the product. A score is a starting point for your own checking, never a guarantee that the token is safe.
Two terms carry this whole article, so quick glosses first. A score is a single number or grade that squeezes many separate checks into one verdict; the squeeze is the value and the danger at the same time. An authority is a permission switch on a Solana token. Mint authority lets its holder create new supply from nothing. Freeze authority lets its holder lock a wallet so the owner cannot sell.
Everything a scanner reads is public chain data. Permission switches, liquidity, the holder list: you could check all of it by hand, and twenty minutes per token is a realistic manual pace once you know where to look. A scanner does a first pass in seconds. That speed is real value, as long as you remember what the pass skipped.
Comparison table
The table describes each product by its main public focus, nothing more. We quote no prices anywhere in this article, because pricing shifts and a stale number is worse than none; the current state is always on each product's own site.
| Tool | Main focus | Gives a score | Solana focus | Shows wallet relationships | Pricing |
|---|---|---|---|---|---|
| RugCheck | Solana token risk reports and authority checks | Yes | Yes, Solana-native | Not the main product | On their site |
| Solsniffer | Solana risk score plus deeper contract analysis | Yes | Yes | Not the main product | On their site |
| TokenSniffer | Multi-chain token score with EVM roots | Yes | Multi-chain, strongest on EVM chains | Not the main product | On their site |
| Bubblemaps | Visual map of holder wallets and connections | No, it is a map | Multi-chain, Solana included | Yes, as a visual map | On their site |
| DexScreener | Market data: price, volume, liquidity charts | No, not a safety tool | Multi-chain, Solana included | No | On their site |
The last two rows need a caveat. Bubblemaps and DexScreener sit in this table because buyers use them next to scanners, not because they compete on scoring. DexScreener tells you what the market is doing. Bubblemaps shows who holds a token and how those wallets connect, which no score number carries.
A note for anyone hunting a TokenSniffer alternative for Solana work. EVM means Ethereum and the chains built like it, and TokenSniffer grew up reading that style of contract code. Solana tokens do not work that way, so for a Solana token, RugCheck and Solsniffer are the natural first stops.
What goes into a safety score?
Score recipes differ tool by tool, but they draw from the same short menu of inputs:
- Mint authority. Is the switch that creates new supply still active? If it is, whoever holds it can print more tokens and shrink the value of everyone else's holdings in one move.
- Freeze authority. Can someone lock individual wallets? A frozen wallet cannot sell, and locking buyers in place is a classic trap design.
- LP lock or burn. LP means liquidity pool, the shared pot of token plus SOL that makes trading possible at all. An LP lock keeps the creator from pulling that pot out for a set period; a burn gives up control of it permanently. Either way, holders keep an exit.
- Holder concentration. How much of the supply do the top wallets control? A single wallet holding a third of everything can crush the price whenever it likes.
- Contract and extension checks. On EVM chains this means scanning code for known trap patterns. On Solana it increasingly means Token-2022 extensions, built-in settings such as transfer fees that ride inside the token itself.
Every one of those checks can be done manually, and knowing the manual route is what turns scanner output from a mystery grade into something you can actually read. We keep the full step-by-step in our manual rug pull checklist, so it will not be repeated here. Short version: the scanner reads the settings, and you still judge what the settings mean together.
Does a high score mean a token is safe?
No, and this is the section worth slowing down for. A clean score means clean in the measured areas. It says nothing about the unmeasured ones, and the people who design bad tokens know precisely where the measurement stops.
Here is a pattern that keeps showing up, described without naming anyone. Mint authority revoked. Freeze authority revoked. LP burned. Every box a score checks comes back green, and the token can score well. Meanwhile, most of the supply sits across a few dozen wallets that were all funded from the same source within an hour of launch. On paper, dozens of independent holders. In practice, one seller wearing dozens of masks, positioned to exit into your buy. A score built from authorities and liquidity has no reason to catch this, because nobody asked it to look at who funded whom.
That is the honest answer to the RugCheck score meaning question people keep searching. The score is an accurate summary of specific checks, produced by a tool doing exactly what it promises. The gap appears on the reader's side, in the leap from "the measured checks passed" to "this token is safe". RugCheck itself lists component flags beneath the headline number, and those flags deserve more of your attention than the number does.
One blind spot gets its own paragraph: Token-2022, the newer of Solana's two token standards (the original is called SPL). Tokens on the newer standard can carry built-in behavior, transfer fees among them, that changes what a sell actually returns. Scanner coverage of these settings varies. If a token uses the newer standard, understand its extensions before buying; our Token-2022 vs SPL token guide explains them in plain language.
A score is a snapshot of the second it was generated. Liquidity can move, locks expire, new pools appear and top holders reshuffle within hours. Run the check again right before you buy, not the night before.
What does no scanner make its main product?
Score tools compress settings into a grade. Bubblemaps draws the holder map, and the visual side is genuinely good; a cluster of connected bubbles lighting up is often the moment a buyer first feels the problem. What we kept hitting was a workflow gap in the minute before a buy: you have a list of top holders in front of you and one question. Who funded these wallets, and are they actually independent of each other?
The question matters more on Solana than almost anywhere else because of launch culture. New tokens appear by the hundred every hour, wallets cost nothing, and splitting a position across twenty addresses takes a minute. Distribution that looks organic on the surface is cheap to fake. Funding history is expensive to fake, because the SOL that opened each wallet had to come from somewhere, and that trail stays on the chain.
This is the question our two free tools answer, Solana-native and shaped for the pre-buy minute. Wallet Scope traces funding links: paste the wallets you are unsure about and it shows who funded whom, shared funding sources and the cluster structure inside your pasted list. Token Snapshot pulls the holder spread: the full holder list with each wallet's share, exportable straight into the first tool. Both free, no account needed.
Two honest limits, since this article promised fairness. First, funding links are signals, not proof of intent. Wallets sharing one funding source can be a single person's sock puppets, or a team wallet paying contributors, or something else entirely; the pattern tells you where to ask harder questions, it convicts nobody. Second, Wallet Scope does not give you a score. If you want a one-number answer, the score tools do that job and we do not. You leave with a relationship breakdown you still have to think about yourself.
What is a sensible pre-buy check order?
No single product covers the whole picture, so run a sequence. Cheap and fast checks first, judgment last.
- Run the token's address through a score tool. RugCheck or Solsniffer for a Solana token. Skip the headline number at first and read which component checks passed and which failed.
- Confirm the authorities. For a fixed-supply community token, mint and freeze authority should both be revoked. If either is still live, you want a stated reason from the team.
- Check the liquidity. Is the LP locked or burned? Is the pool deep enough that a normal-sized sell will not crater the price? DexScreener's market view helps with the second half.
- Pull the holder spread. Take a snapshot of all holders: the combined share of the top ten, the total holder count and the age of the biggest wallets.
- Trace the relationships. Paste the top holders into a funding check and look for one source feeding many wallets, same-day creation batches or tight clusters.
- Make a tiny test trade. Buy a small amount and sell it straight back. If the exit fails or a surprise fee appears, you learned it with pocket change instead of your position.
The whole loop takes about five minutes once it is familiar. Most rug victims never traced a single funding link. That check is not hard; it simply never appeared in front of them, because no score includes it.
Frequently asked questions
Which token scanner is best?
There is no single best Solana token checker, because each product answers a different question. RugCheck and Solsniffer read Solana natively, TokenSniffer covers EVM chains, Bubblemaps maps holders visually and DexScreener covers markets. The strongest setup is a small stack: one score, one liquidity view, one relationship check. Pick per question, not per brand.
What RugCheck score counts as safe?
We will not hand you a threshold, and you should distrust anyone who does; the vendors themselves present scores as summaries, not clearance. Open the component list under the number and read which checks passed, which failed and what got flagged. One specific failed check tells you more than any headline grade.
Are these scanners free?
Most of them offer free checking with paid tiers on top for extra depth or volume. We quote no prices on purpose; they change, and a stale figure would mislead you, so treat each product's own site as the source of truth. The two j.tools utilities linked above are free.
Can a scanner prevent a rug pull?
No. A scanner surfaces risk before you commit money; it has no power over what happens afterward. It cannot stop a large holder from dumping, a team from walking away or an unlocked pool from being drained. Treat it as a flashlight rather than a seatbelt: what it reveals still has to change your decision.
Bubblemaps or Wallet Scope, which should I use?
They are complementary. Bubblemaps gives you a visual map of holders and connections across several chains, strong for seeing structure at a glance. Wallet Scope takes a list you paste and returns a relationship breakdown: who funded whom, shared sources, clusters. Plenty of careful buyers glance at a map first, then run the list through the breakdown.
Is this comparison sponsored?
No. There are no affiliate links here, no product paid for placement and no ranking was sold. We build two free tools in the same neighborhood, which gives us an obvious interest, so we said it in the opening instead of burying it. Verify every claim yourself; that habit is the entire point of this article.
