What Is a Wallet Safety Check?
A wallet safety check evaluates whether a blockchain wallet is safe to interact with. Every transaction on a public ledger leaves a permanent trail, and that trail reveals a lot about who you're dealing with — whether they've laundered funds through a mixer, touched sanctioned addresses, or belong to a coordinated sybil cluster.
Guava's wallet safety check pulls on-chain data from multiple sources across 31 chains and runs it through a multi-dimensional risk engine. In under two seconds you get a clear safety score, a breakdown of every risk factor detected, and an AI-generated summary that tells you exactly what to watch out for.
Use it before copying a whale's trades, sending funds to an unknown address, onboarding a new counterparty, or vetting a project team wallet. The check is free, requires no signup, and works on any public wallet address.
What We Check
Every wallet safety check runs these security analyses automatically across 31 chains.
Mixer Interactions
Detect any transfers to or from known tumblers and mixing services like Tornado Cash that obscure fund origins.
Blacklisted Addresses
Flag wallets that have sent or received funds from OFAC-sanctioned or exchange-blacklisted addresses.
Sybil Cluster Detection
Identify wallets that belong to coordinated sybil farms — groups of addresses controlled by a single entity.
Scam Exposure
Surface interactions with known scam contracts, phishing drainers, honeypot tokens, and rug-pull deployers.
Transaction Patterns
Analyse transfer frequency, gas usage, and behavioural anomalies that indicate bot or wash-trading activity.
Portfolio Risk
Evaluate the risk profile of every token the wallet holds — high-risk token exposure drags up the overall score.
Wallet Age Assessment
Newly created wallets carry higher risk. We factor in first-activity date and on-chain history length.
Coordinated Activity
Detect wallets that move in lockstep — a hallmark of airdrop farming, wash trading, and market manipulation.

Why Wallet Safety Matters
Without a Safety Check
- You copy-trade a wallet funded by a mixer
- You send funds to an address later flagged as sanctioned
- You interact with a sybil cluster and get blacklisted from airdrops
- Your exchange freezes deposits linked to tainted funds
With a Guava Safety Check
- See mixer and blacklist exposure before you transact
- Detect sybil clusters and coordinated wallet activity
- Get a clear safety score and AI summary in seconds
- Interact with confidence across 31 chains
Who Uses the Wallet Safety Check?
Traders
Check a whale or counterparty wallet before copying trades or sending funds. Confirm they're clean — not a mixer-funded bot.
DeFi Investors
Vet project team wallets and early investors for sybil activity and scam exposure before committing capital.
Airdrop Hunters
Verify your own wallet's on-chain history is clean so you don't get flagged as a sybil and disqualified.
Exchanges & Protocols
Run safety checks on wallets interacting with your platform to block tainted funds and sanctioned addresses.
Researchers
Investigate on-chain clusters, sybil farms, and coordinated wallet activity across 31 chains.
Security Teams
Flag wallets linked to known exploits, mixers, drainers, or blacklisted addresses before they cause damage.
Frequently Asked Questions
What is a wallet safety check?
A wallet safety check analyses a blockchain wallet address and evaluates how safe it is to interact with. It looks at on-chain behaviour — mixer interactions, blacklisted contacts, sybil clustering, scam exposure, transaction patterns, and portfolio risk — and produces a clear risk score so you can decide whether to trust the wallet.
Is the wallet safety check free?
Yes. You can run a wallet safety check on this page without signing up. Free accounts get 10 scans per day and no credit card is required. Create a free account to save analyses, follow wallets, and set up alerts.
How is a wallet safety check different from a wallet risk checker?
They cover the same underlying analysis. A wallet safety check focuses on whether a wallet is safe to interact with — emphasising mixer exposure, blacklists, and scam contacts — while a wallet risk checker emphasises the composite risk score. Both run the same multi-chain engine on Guava. You can try our Wallet Risk Checker for the full score breakdown.
Which chains does the wallet safety check support?
31 chains: Ethereum, Solana, Bitcoin, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Blast, zkSync, Linea, Scroll, Mantle, and more. The checker on this page defaults to Ethereum but you can switch to Solana, BSC, Base, or Arbitrum instantly.
What does the wallet safety score mean?
The score (0–100) is calculated from five components: Profitability (25%), Risk Exposure (30%), Token Quality (20%), Gas Efficiency (15%), and Behavioural Stability (10%). A lower score means a safer wallet; a higher score means greater risk from mixers, blacklists, scams, or suspicious behaviour.
Can I check a wallet I don't own?
Yes. All blockchain data is public. You can run a wallet safety check on any address to do due diligence before trading with, copying, or sending funds to that wallet.
What happens if a wallet has interacted with a mixer?
Mixer interactions are a strong risk signal. Wallets that have sent or received funds from tumblers like Tornado Cash are flagged because mixed funds are often linked to hacks, exploits, or sanctioned entities. The safety check surfaces these interactions so you can avoid tainted funds.
Does the wallet safety check detect sybil wallets?
Yes. Guava runs sybil and clustering detection that identifies wallets controlled by a single entity — a common pattern in airdrop farming, wash trading, and coordinated manipulation. Sybil-linked wallets receive a higher risk score.
