What Happens When You Check an Address
Paste any crypto address and Guava pulls on-chain data from multiple sources to build a complete risk profile in seconds.
Mixer Interactions
We flag any address that has sent to or received from known tumblers and mixing services such as Tornado Cash.
Sanctions Lists
We screen every address against OFAC SDN and other global sanctions lists to surface legally restricted wallets.
Scam Associations
We cross-reference the address against reported scam, phishing, and drainer databases to identify fraud-linked wallets.
Cluster Activity
We detect coordinated behaviour — sybil clusters, fund-rotation rings, and wallets controlled by the same entity.
Transaction History
We summarise recent transfers, DEX trades, and gas patterns so you can see how the address actually behaves on-chain.
Portfolio & Holdings
We pull token holdings and USD values across every supported chain for a complete picture of the address.

What We Check
Every crypto address check runs these security checks automatically, powered by GoPlus Security, RugCheck, and global sanctions data.
Why an Address Risk Check Matters
Sending funds to the wrong address is irreversible. A quick address risk check protects you from sanctioned counterparties, scam wallets, and tainted funds.
Avoid Sanctioned Wallets
Transacting with OFAC-sanctioned addresses can create legal exposure. Screen every counterparty first.
Reject Tainted Funds
Receiving from mixers or flagged wallets can get your own address blacklisted by exchanges.
Spot Scam Wallets
Identify addresses linked to phishing, drainers, and known scams before you interact with them.
Uncover Clusters
See whether an address is part of a sybil farm or coordinated fund-rotation ring.
Verify Before You Send
Confirm an address's history and holdings before sending funds you can never recover.
Watch Addresses (Pro)
Get alerted via Telegram or email whenever a watched address has new on-chain activity.
Frequently Asked Questions
What is a crypto address checker?
A crypto address checker is a tool that analyses a blockchain address and reports its risk profile — including mixer interactions, sanctions hits, scam associations, cluster activity, and transaction history. Guava's crypto address checker runs all of these checks across 31 chains in seconds.
Is the crypto address checker free?
Yes. You can run a blockchain address check on this page without signing up. Free accounts get 10 scans per day and no credit card is required.
Which blockchains can I check an address on?
31 chains including Ethereum, Solana, Bitcoin, Base, Arbitrum, BNB Chain, Tron, Optimism, Polygon, Avalanche, Blast, zkSync, Linea, Scroll, Mantle, and more.
What happens when I check an address?
Guava fetches the address's portfolio and transaction history, screens it against sanctions and scam databases, checks for mixer interactions and cluster activity, and returns a composite risk score with a full breakdown — all in under 2 seconds.
Can I check any crypto address, even one I don't own?
Yes. All blockchain data is public. You can run a crypto address lookup on any wallet to perform due diligence before sending funds to it, trading with it, or copying its activity.
What does the address risk score mean?
The 0–100 score is calculated from on-chain behaviour, token quality, transaction history, and security flags. A higher score indicates a riskier address. Each report breaks down exactly which factors drove the score.
Does the checker detect sanctioned addresses?
Yes. Every address is screened against OFAC SDN and other global sanctions lists. Wallets that appear on these lists are flagged immediately so you can avoid legally restricted counterparties.
What is a crypto address lookup vs a wallet risk check?
A crypto address lookup is the act of searching an address to retrieve its on-chain profile and risk signals. A wallet risk check is the broader analysis that produces a risk score from those signals. Guava performs both in a single report — see our Wallet Risk Checker for the full scoring methodology.
