One score, with reasons
Every report opens with a 0–100 Risk Score, a confidence level and the main reasons. When data is thin, the score says so instead of guessing.

How it works
From address to answer in three steps
No account and no wallet connection. Open the extension and check the address you are about to use.
- 01
Open or paste an address
Paste any address, or open it on a block explorer and let the scanner pick it up. The network is detected for you.
- 02
Get a risk score
One number from 0 to 100 with a confidence level. Higher means riskier, and the top reasons are listed right under the gauge.
- 03
Check the evidence
See the sanctions result for each source, the assets and recent activity, then ask Copilot follow-up questions in plain language.
Features
Everything you need to judge an address
The same report you see in the extension, built from public on-chain data and AML sources.
Sanctions screening by source
Addresses are checked against the U.S. Treasury OFAC list. On Ethereum mainnet a private risk database adds labels such as phishing or theft. Each source shows its own result.
Finds addresses on the page
Open a block explorer or a Web3 site and the extension lists the addresses it sees. Detection runs locally in your browser.
Assets and activity in one view
Balances, tokens with USD estimates and recent transfers. ERC-20, SPL, TRC-20 and TON jettons; UTXOs and mempool activity for Bitcoin.
Ask about the wallet
Ask a question about the report and get a plain-language answer in your interface language. Available for Ethereum and EVM networks.
Save and compare wallets
Keep the wallets you check often in one list and compare two addresses side by side. Saved wallets and names stay in your browser.
Risk Score
How to read the score
The score runs from 0 to 100. Higher means riskier. The label and colour always come together, so the meaning never depends on colour alone.
23/ 100
Low risk16–30
Confidence matters
High, medium or low confidence shows how much data the score rests on. A low-confidence score is a reason to look closer.
Gaps raise the floor
If a sanctions check is incomplete or there is too little data, the score stays at 51 or higher. Missing evidence is never shown as safe.
Not a guarantee
“No matches” means the checked sources have no record of this address. New scam addresses appear every day, so treat the score as one input.
What score would your next transfer get?
Check the address before you send. Free, no wallet connection, no sign-up.
Privacy
Read-only by design
Web3 Copilot reads public blockchain data. It cannot touch your funds.
No wallet connection
You never connect a wallet, sign a message or enter a seed phrase. The extension cannot move funds.
Local detection
Finding addresses on a page happens in your browser. Saved wallets, names and report snapshots stay on your device.
Analysis on request
When you click Get score or ask a question, the address, network and needed context go to our API and its data and AI providers.
Free, with fair limits
No subscription or paid tier. Free use has a rolling 24-hour limit that keeps the service fast for everyone.

FAQ
Questions and answers
Is Web3 Copilot free?
Yes. There is no subscription, paid tier or premium upgrade. Free use is rate-limited, so after many checks within 24 hours you may need to wait before the next one.
Do I need to connect my wallet?
No. Web3 Copilot only reads public blockchain data for the address you check. It never asks for a seed phrase, private key or signature, and it cannot move funds.
Which networks are supported?
Ethereum, BNB Chain, Polygon, Arbitrum, Base, Optimism, Avalanche, zkSync, Linea, Scroll, Solana, TRON, Bitcoin and TON.
What does the Risk Score mean?
It is a number from 0 to 100 where higher means riskier. It combines the on-chain evidence and AML results available for the address, and comes with a confidence level and the main reasons.
Does “No matches found” mean an address is safe?
No. It means the sources we checked have no record of the address. Each source covers specific networks, and new scam addresses appear every day. Treat the result as one input, not a guarantee.
Which sanctions lists do you check?
The U.S. Treasury OFAC sanctions list, plus a private risk database for Ethereum mainnet. The report shows which source checked which network and what it found.
What data leaves my browser?
Address detection and your saved wallets stay local. When you request an analysis or ask a question, the address, network and needed context go to our API and its data and AI providers. The Privacy Policy has the details.
Is this financial advice?
No. Web3 Copilot is a research tool. Reports do not recommend transactions or certify that an address is safe. You decide what to do with your funds.
