Free Crypto Address Risk Checker

Check wallet risk signals before you send funds

Paste an EVM address, choose a chain, and review known risk signals, behavior patterns, and confidence level. The result is intentionally conservative: no known reports does not mean verified safe.

Known scam lists Behavior signals Confidence score Not verified safe

Enter address

EVM-only in v1. Ethereum, Polygon, Arbitrum, Optimism, Base, BSC, and Avalanche are supported. Data comes from Alchemy, Covalent, Etherscan, and community blacklists.

Warning: this tool only checks known data sources. New, private, or unreported scams will not be detected. A low-risk result is not a safety guarantee.

What you will see

Risk status

Known High Risk, Suspicious Activity, No Known Reports, or Limited Data. The label is conservative by design.

Confidence

Confidence reflects how much history and how many sources were available. Low confidence means the tool does not know enough yet.

Signals

Each finding is shown with the source and reason so users can inspect the evidence instead of trusting a black-box verdict.

How the checker works

1. Known reports

The first pass checks community blacklists and security labels. If the address is flagged, the tool surfaces it immediately.

2. Behavior signals

Next it looks at transaction velocity, mixer exposure, flagged counterparties, contract activity, and fresh-wallet patterns.

3. Confidence

Finally, it scores how much data was available. Sparse history lowers confidence even when no obvious warning signs appear.

What the labels mean

Known High Risk

The address matched a blacklist, malicious label, freeze tag, or similarly strong warning source.

Suspicious Activity

The address shows one or more behavior-based warning signals even if it is not on a blacklist.

No Known Reports

No known warning sources matched, but this still does not prove the address is safe or clean.

Limited Data

The address has too little verified activity or too few sources to form a confident view.

Frequently Asked Questions

Does a clean result mean an address is safe?

No. A clean result only means the tool did not find known risk signals in the sources it checked. New scams, private wallets, and unreported behavior will not be detected. The correct interpretation is "no known reports" rather than "verified safe".

What sources does the checker use?

The checker is designed to combine community blacklist data, Alchemy transfer history, Covalent address activity, Etherscan account data, and local behavior rules. It looks for blacklist matches, mixer exposure, unusual activity velocity, multi-chain bursts, and similar warning signals.

Can it detect frozen or blocked wallets?

Only when the source data explicitly marks an address as frozen, blocked, sanctioned, or otherwise restricted. The tool does not guess. If no source reports a lock or freeze, it will not claim one exists.

Why show confidence separately from risk?

Risk tells you what the tool found. Confidence tells you how much evidence it had. A wallet can look low risk while still having low confidence if it has very little on-chain history or few verified sources.

Is this a compliance or legal screening tool?

No. It is an informational risk signal checker, not legal advice and not a sanctions-screening product. It can help surface warning signs, but it cannot replace official compliance checks or professional due diligence.
