Frequently asked questions

Yes — every check on this website is free, forever, no registration. We make money from the optional deep-report tier in the Telegram bot, where the first three reports are also free.

No. No email, no phone, no captcha. Open the page, paste an address, see the result.

Bitcoin, Ethereum, all major EVM L2s (Polygon, Arbitrum, Optimism, Base, BNB Chain, Avalanche), TRON, Solana, Cosmos, NEAR, Ripple, Cardano, Polkadot, Litecoin, Dogecoin and more. The address format is auto-detected.

We aggregate 50+ public and licensed data sources updated multiple times per day. Direct sanctions matches are essentially 100% accurate; indirect risk scoring (multi-hop exposure) is heuristic and can disagree across vendors by 10–15 points for the same wallet.

We may not catch it. Most data feeds have a lag of a few hours to a few days for new additions. For anything older than 24 hours, our coverage is strong.

0–25 is low risk — safe to transact. 26–50 is medium — pause and consider alternatives. 51–75 is high — likely problems with this wallet, walk away. 76–100 is critical — sanctions or active scam, do not engage.

Usually because it interacted with a contract or token that was later flagged. This is most common on Ethereum and Solana, where many "innocent" airdrops turn out to be scam-adjacent. The Telegram bot's deep report shows exactly which interactions are driving the score.

Yes. If you believe a wallet is incorrectly flagged, contact our support via Telegram with the address and your evidence. We review every dispute manually.

We cache a hash of the address for performance, but never the address-to-IP link. The raw address is not stored.

Only in standard web server logs, rotated and discarded after 30 days. We do not link IPs to checked addresses.

No. We do not run as a regulated entity and we do not respond to ad-hoc data requests. We comply with court orders when properly served, but the data we hold is minimal — see the privacy policy.

Do not deposit to a regulated exchange. Contact your exchange's compliance team first, in writing, with the transaction details and the source. Most cases resolve when you are upfront. Hiding the source and hoping nobody notices is the fastest way to lose your account.

Cooperate, don't escalate. Provide source-of-funds documentation, invoices, P2P chat screenshots. Most exchanges restore access once they have a clean paper trail. A coming blog post walks through this in detail.

We can give you the full transaction graph (via the Telegram bot's deep report) which is useful for police reports and Chainabuse filings. We cannot recover funds — nobody legitimate can. Be very suspicious of anyone who claims they can.

A score of 51–75 means the wallet has direct connections to addresses in scam databases, community-reported fraud, or behavioral patterns associated with illicit activity (rapid fund forwarding, single-use wallet creation). It does not guarantee the wallet is actively scamming you right now — but the probability is high enough that you should not transact with it without further verification.

Technically yes — nothing prevents the transfer. But if you then deposit those funds to a regulated exchange (Binance, Coinbase, Kraken), the exchange will screen the source and may restrict your account. For scores above 50, the safe answer is: ask the sender for a different wallet or for documented source-of-funds, and keep the conversation in writing.

OFAC SDN updates are pulled within 4 hours of publication. EU and UN lists are refreshed daily. Ransomware and scam wallet reports from Chainabuse and community sources are integrated multiple times per day. Some exchange blacklists update weekly. For wallets involved in the last 24 hours, our coverage may lag — but for anything older than that, it is comprehensive.

The checks run against the same core databases (OFAC SDN, EU sanctions, ransomware, exchange blacklists). But the specific databases and risk signals differ by blockchain. For USDT TRC-20, we also check the Tether blacklist and TRON-specific fraud patterns. For Bitcoin, we check UTXO-based coin clustering and mixer exposure. For Ethereum, Tornado Cash exposure and DeFi rug pulls are the main additions. Each chain has its own specialized signals.

Go to cryptoaml.cc/usdt-check or paste the T-address (starts with T) on the main page. The checker auto-detects TRON. For a deeper check including Tether's blacklist status and the full transaction graph, use @scorechain_amlbot in Telegram.

Yes. Polygon, Arbitrum, Optimism, Base, BNB Chain and Avalanche all use the same 0x address format as Ethereum. Paste the address and our checker looks across all EVM chains simultaneously. The Polygon checker has specific details about what we look for on that network.

Yes. Solana addresses are 32–44 character base58 strings. Our checker covers OFAC matches, darknet activity on Solana, scam SPL token deployers, and community fraud reports. Solana-specific risk (meme coin rug pulls, fake NFT mints) is included.

Yes, on request. Contact us via the Telegram bot for API access and pricing.
