Imagine opening your wallet and finding every coin gone. In 2024 alone, hackers and scammers drained more than $10 billion from holders. Price charts never reveal a tainted address or a back-doored contract, so hidden risks slip past seasoned traders.
Wallet-risk scanners close that gap. They grade addresses in real time, flag stolen or sanctioned funds, and warn when a Bitcoin public key is vulnerable to future quantum attacks.
We tested nine standout tools—from bank-grade AML engines to free browser checks—to help you pick the right shield.
Before the reviews, here’s the scorecard we used.
How we picked the winners
We didn’t grab the first nine tools on Google. We vetted wallet-risk scanners the way a bank vets loan applicants: every claim had to pass a stress test.
First, we mapped the field. Trading scanners, price bots, and generic block explorers were tossed out. We focused only on services that judge the safety of an address or the code that controls your funds.
Next, we ran each candidate through six hard questions:
Accuracy – Does the engine catch dirty money or hidden backdoors?
Coverage – How many blockchains and asset types does it watch?
Ease of use – Can a newcomer get a result in seconds, or is it an API for engineers only?
Cost – Free tier, pay-per-check, or enterprise invoice?
Data freshness – Are risk scores updated continuously or once a month?
Transparency – Is the methodology open, or a black box you must trust on faith?
We weighted accuracy and freshness the heaviest. A slick dashboard is useless if it misses a sanctioned wallet an hour after the list changes.
Finally, we matched scanners to real-world roles. A solo DeFi trader needs different armor than a regulated exchange, so our lab tests crowned clear “best for” winners instead of handing out generic praise.
Project 11’s Bitcoin Risq List currently flags about 6.7 million BTC—roughly one-third of the supply—as quantum-vulnerable.
That concrete metric guides treasuries looking to future-proof reserves, yet it is largely irrelevant to day-traders chasing meme-coin pumps.

1. Project Eleven Bitcoin Risq List
Best for spotting quantum-age weak spots
Bitcoin cryptography feels unbreakable today, yet every time a public key appears on-chain it becomes a future target for quantum computers. Project 11’s live Bitcoin Risq List clocks the damage in real time—about 6.7 million BTC flagged in its latest weekly scan—so the threat is no longer abstract. According to Encryptos research, an estimated 25–33 percent of all BTC already sits in addresses with exposed public keys.
Project Eleven Bitcoin Risq List quantum-vulnerable BTC dashboard
Project Eleven watches that silent threat in real time. Its open-source dashboard scans the entire Bitcoin blockchain each week and produces a live list of wallets whose public keys leaked through address reuse, P2PK outputs, or partial spends. Paste any address and you see a clear verdict: secure for now or quantum-vulnerable, plus an explanation.
The service also charts total BTC at risk over time, so custodians can track the needle and act before hardware advances. Because the code is public, auditors can verify the math instead of trusting a black box.
Who should care? Long-term BTC holders, treasuries, and exchanges managing deep cold-storage positions. If an address lands on the Risq List, the remedy is simple: sweep funds to a fresh, never-spent address and rest easier.
No other tool in our lineup addresses tomorrow’s quantum heist at zero cost. For that niche but critical job, Project Eleven stands alone.
2. Chainalysis KYT
Best for enterprise AML and sanctions defense
When regulators call, they do not accept “we didn’t know.” Chainalysis equips exchanges and banks with live data to prove they do know, in real time.
Chainalysis KYT real-time crypto transaction monitoring dashboard
KYT (Know Your Transaction) screens every deposit, withdrawal, and liquidity-pool hop against the world’s largest attribution database. If an address links to ransomware, darknet markets, or an OFAC blacklist, the system stops the transfer on the spot. Chainalysis sums up the promise in a single line: “Detect and block risky wallets instantly.”
Coverage spans more than 100 blockchains and thousands of tokens, so cross-chain mixers and bridges lose their hiding places. Scores refresh continually, so you never need to rerun yesterday’s address.
Developers switch on a REST API, set a risk threshold, and route alerts straight into case-management tools. Compliance officers see color-coded dashboards that turn on-chain noise into a clear pass or fail.
KYT has no public free tier and targets enterprise budgets, yet that expense is modest compared with a regulatory penalty or frozen client funds.
If your platform processes high volume and you need audit-ready proof that every address was screened, KYT remains the benchmark.
3. TRM Labs
Best for live cross-chain threat tracking
Crypto crime crosses chains, and TRM keeps pace. The platform ingests data from about 24 blockchains, links wallets that move through bridges within seconds, and revises risk scores as soon as new intelligence arrives.
Enter a deposit address once and TRM monitors it indefinitely. If that wallet later touches a hacked DeFi pool or appears on a sanctions list, your team receives an alert before the funds settle in cold storage. Continuous monitoring removes the hazard of retroactive toxicity: coins that start clean but turn radioactive days later.
The interface shows risk timelines, entity clusters, and click-through graphs that non-technical staff can grasp. An API streams the same feed into exchange back ends, so compliance runs at network speed.
Pricing is similar to Chainalysis, and there is no public free check. For businesses that operate across multiple chains, the subscription buys instant visibility that spreadsheets cannot match.
4. Elliptic Navigator
Best for bank-ready transparency
Elliptic meets traditional finance on familiar ground. Its risk engine assigns green, yellow, or red scores and explains each verdict in plain English. Compliance teams can capture the page and walk straight into an audit meeting.
Breadth sets it apart. The platform tracks more than 100 assets, including privacy coins and niche sidechains that bad actors use when Ethereum draws attention. If an address tied to a sanctioned oligarch hops chains, Navigator flags it.
The “Lens” quick-check tool earns praise. Paste an address and you see both the score and the origin of funds: percentages from mixers, gambling sites, and regulated exchanges. That context shows whether the risk stems from a single shady hop or a long criminal history.
Pricing targets enterprises, yet many neobanks and payment apps pay for clarity. If your board wants straightforward reports without jargon, Elliptic delivers.
5. Scorechain Free AML Check
Best for quick, no-cost peace of mind
Sometimes you just need a fast yes or no before sending funds. Scorechain’s free web checker provides an answer in under ten seconds.
Scorechain Free AML Check public crypto address screening tool
Paste any Bitcoin, Ethereum, or stablecoin address into the form and see a risk score plus a pie chart of fund origins. If part of the flow comes from mixers or darknet markets, the bar turns orange. A green bar signals that the payment is likely safe to accept.
Because the tool sits on a public site, there is no onboarding delay. Freelancers, OTC desks, and crypto ATM operators use it as a first gatekeeper, then upgrade to the full platform when volume rises.
Reports export to PDF, giving small businesses a lightweight audit trail if questions appear later.
Scorechain will not replace Chainalysis, yet it delivers strong value at a price of zero for basic checks.
6. TokenSniffer
Best for dodging scam tokens before purchase
DeFi moves fast, and scammers move faster. TokenSniffer is your pit stop: paste the contract and see if the wheels fall off.
Within seconds the site inspects smart-contract code and returns a Safety Score from 0 to 100. A low score usually flags one of three risks: trading disabled (honeypot), an owner wallet holding most of the supply, or cloned code from a known rug pull.
The interface is blunt on purpose. Oversize red warnings feel like a mechanic shouting, “Don’t drive this.” If the score is green, you still research further, but at least the brakes work.
Coverage spans Ethereum and BNB Smart Chain, which host most meme-coin drama. The price is zero, so TokenSniffer becomes an easy first check for any trader tempted by shiny new tokens.
Copy the contract, sniff it, and keep your stack safe.
7. GoPlus Security API
Best for builders who need risk data on tap
If TokenSniffer is a roadside check, GoPlus is the full diagnostic suite. Wallets, dApps, and explorers embed its API to warn users before they sign a risky transaction.
One endpoint flags malicious contract code, another scores wallet behavior, and a third blocks known phishing URLs. Each returns JSON in milliseconds, so developers can raise red banners the moment a user pastes an address.
Coverage spans about forty blockchains, from Ethereum mainnet to new L2s, letting apps offer the same safety net wherever users roam.
The public tier is rate-limited yet roomy enough for prototypes. Production work shifts to a paid plan, which still costs less than coding an in-house scanner and sourcing threat feeds.
If you build anything that touches user funds, piping GoPlus into the backend is the fastest route to baked-in security.
8. De.Fi Shield
Best for tidying up your own wallet
Think of De.Fi Shield as a security checkup for everything in your MetaMask. Connect, run a scan, and the dashboard lists token approvals, contract risks, and an overall Wallet Score.
De.Fi Shield wallet approval risk and one-click revoke dashboard
If Shield finds an unlimited spend approval to a suspect contract, it marks the row in red and offers a one-click revoke. It also flags spam airdrops that can trigger a drainer when you move them.
Scans cover major EVM chains such as Ethereum, BNB, Polygon, and Arbitrum, giving multi-chain DeFi users the same clarity everywhere. Basic scans are free, so you can run one monthly, weekly, or any time a new protocol dangles high yield.
No AML features, no enterprise pricing, just straightforward hygiene that prevents self-inflicted losses.
9. Janus Open-Source Scorer
Best for tech-savvy users who trust code, not marketing
Janus returns wallet screening to first principles. Clone the GitHub repo or open the Colab notebook, enter a Bitcoin or Ethereum address, and watch JSON results appear.
The script cross-references public scam lists, darknet tags, and hacker wallets. If the address interacted with a breach or mixer, the audit shows when and how much. Every query is visible in plain text, with no paywall or secret algorithm.
Running Janus requires basic command-line skills, so it may not suit non-technical users. The transparency lets researchers fork the code, add data sources, and verify each heuristic step by step.
Small exchanges on tight budgets, students studying crypto forensics, and anyone wary of black boxes gain a rare chance to inspect the math behind a risk score and refine it as needed.
Conclusion
We tested nine standout tools—from bank-grade AML engines to free browser checks—to help you pick the right shield.
