Start with the network: a checker is useless if it does not cover the chain your funds move on. Then compare price per check (and free checks), whether the report shows categories and sources, who operates the service, and whether it works without an account or wallet connection.
1. Network coverage
Coverage varies a lot. Among the services we track, MistTrack confirms 9 of the 10 networks we follow, while AMLCrypto covers Bitcoin, Ethereum and TRON. Each service in the rankings lists the networks it supports, and the network matrix compares them side by side.
2. Price per check
Published prices range from free basic checks to around $1 a check for single paid checks; packages bring the price down. Some services show prices only after sign-up or on request. Compare in the price table.
3. Report depth
- Is there a numeric score?
- Does it break the risk down by category?
- Can you download a PDF for an exchange?
- Can it check a transaction hash, not only an address?
4. Who runs it
A named company with terms and a privacy policy stands behind its report. Anonymous checkers can still be useful for a quick look, but their report carries less weight in a dispute.
5. Privacy
You should never need to connect a wallet. Some services work without an account; others need sign-up even for the free check.
How we turn this into a score
Our methodology weights these factors — price 20%, networks 20%, report 20%, transparency 20%, privacy 10%, channels 10% — using only facts confirmed on each service’s own pages.

FAQ
Should I use more than one checker?
For large amounts, yes. Providers label different addresses, so a second opinion can catch what the first missed.
Is the most expensive checker the most accurate?
Not necessarily. Accuracy depends on attribution data, which is hard to compare from outside. Prefer services that name their sources.
