Comparison

ScanZX vs TokenSniffer

Both tools give you an automated read on a token contract. They differ mainly in what they do with uncertainty and in what happens after the first look — ScanZX separates 'we found no problems' from 'we could not check', and is built around shareable reports and ongoing monitoring for a community.

TokenSniffer is an independent product and is not affiliated with ScanZX. This page describes what each tool is designed for; it makes no claim about TokenSniffer’s current feature set, which can change at any time.

What each one is

ScanZX

ScanZX produces an explainable observed-risk report: each finding names its source, its severity and the category it belongs to, alongside a separate confidence score describing how much of the intended checking actually ran.

Reports can be published as a public link for a community to read, and tokens can be added to a watchlist for scheduled re-checking with alerts on material change.

TokenSniffer

TokenSniffer is a long-established automated token contract scanner covering multiple chains, best known for producing a quick numeric score for a contract and for its swap-and-contract checks.

It is widely used as a fast first look at a token, and many people know its score format well.

Side by side

DimensionScanZXTokenSniffer
What you get backA risk score plus a separate confidence score, a per-factor breakdown with source and severity for each finding, and an explicit list of checks that could not run.An automated contract score with supporting checks, designed to be read quickly.
How missing data is treatedA check that cannot run lowers the confidence score and never lowers the risk score, so a barely-examined token cannot look better than a thoroughly examined one.Refer to TokenSniffer's own documentation for how it handles unavailable checks.
After the first lookWatchlist monitoring on a schedule set by plan, with alerts on material change — liquidity movement, ownership change, implementation swap where supported.Refer to TokenSniffer's own site for its current monitoring capabilities.
Sharing a resultAny report can be published as a public link with a readable URL and an image card, or kept unlisted. Published links can be revoked.Results are reachable at a per-token URL on their site.
Chain coverageDeep EVM scan on Ethereum, Base, BNB Smart Chain, Arbitrum and Polygon. Baseline market scan on other chains DexScreener lists, plus Solana, labelled as baseline.Multiple chains — see their site for the current list.

What ScanZX does not do

  • Score personal wallets or portfolios. The scanner requires contract code at the address and rejects an ordinary wallet address.
  • Audit source code. ScanZX reads contract properties and behaviour; it does not perform a manual security audit and is not a substitute for one.
  • Predict price, or advise on buying or selling anything. There are no recommendations anywhere in the product.
  • Detect intent. It measures whether a harmful action is possible and how concentrated that ability is — never whether anybody plans to take it.
  • Cover every chain. The deep scan runs on five EVM chains; other chains DexScreener lists receive a baseline market scan only, and that is labelled as such.
  • Guarantee that a token is sound. Every report states observed risk, the checks that could not run, and a confidence score for exactly this reason.

Which one fits

TokenSniffer is likely the better fit when

  • You want a score format you already know how to read at a glance.
  • You need a chain ScanZX does not run the deep scan on — check the chain coverage page first.
  • A single fast look is all you need and you are not going to revisit the token.

ScanZX is likely the better fit when

  • You need to show your reasoning to other people — a public report with per-factor sources is the output, not a number.
  • You care about the difference between 'nothing found' and 'nothing checkable', and want that stated explicitly.
  • You want the token watched after the first scan rather than checked once.

Common questions

Is ScanZX more accurate than TokenSniffer?

That is not a claim ScanZX makes. Automated tools read overlapping data and reach different conclusions in edge cases. What ScanZX commits to is showing its working: every finding names its source and severity, and every check that could not run is listed. Comparing two tools on a token you already understand is a better test than either tool's own marketing.

Can I use both?

Yes, and for anything consequential that is sensible. Where two independent tools disagree, the disagreement itself is the useful signal — it tells you which specific fact to verify by hand.

Does either tool tell me whether to buy?

ScanZX does not, anywhere in the product. It reports observed risk signals and is not financial advice.

See for yourself

The most useful comparison is one you run: scan a token you already understand and see whether the report tells you what you expected. Start from the scanner, read the methodology, or check chain coverage first.

Cryptoassets are high risk and you could lose all money used to buy them. ScanZX reports observed warning signs and data gaps at scan time — it never certifies that a token is safe, it is not financial advice, and it is not a recommendation to buy or sell.
