Question 1

What is AML in crypto?

Accepted Answer

AML (Anti-Money Laundering) is a set of regulations to prevent using crypto for money laundering and terrorism financing. Exchanges check the origin of funds.

Question 2

Why check a wallet address?

Accepted Answer

Before receiving crypto from unknown senders, check the address. If it's linked to scams, sanctions, or darknet activity, an exchange may freeze your deposit.

Question 3

How is the risk score calculated?

Accepted Answer

We check the address against 18 risk factors: sanctions, phishing, mixers, darknet, theft and more. Each factor has a weight based on severity. The final score ranges from 0 (maximum risk) to 100 (clean address). Bands to interpret: 0-30 critical risk (do not accept transfer), 31-69 medium risk (verify counterparty), 70-100 clean address (no detected red flags).

Question 4

Which blockchains are supported?

Accepted Answer

12 major blockchains are supported: Ethereum, BNB Chain, Polygon, Arbitrum, Avalanche, Base, Optimism, zkSync Era, Scroll, Linea, Solana and Tron.

Question 5

How to check a wallet for dirty crypto for free?

Accepted Answer

Paste the wallet address in the field and click Check address. Our tool scans the address for free against GoPlus Security (18 risk factors) and Chainalysis (OFAC sanctions). You get a score from 0 to 100 and a list of detected risks in seconds.

Question 6

Do you store wallet addresses?

Accepted Answer

No. We do not store, log, or share wallet addresses with third parties. The request goes directly to GoPlus Security and Chainalysis, the result is shown to you and stored nowhere.

Question 7

What are the 18 risk factors checked?

Accepted Answer

OFAC sanctions, Cybercrime, Money laundering, Darkweb transactions, Theft/hacking, Financial crime, Blackmail/extortion, Malicious contracts, Phishing, Mixer usage, Honeypot, Fake KYC, Malicious mining, Blacklist suspicion, Fake interface, Fake token, Gas abuse, Reinitialization risk. Each factor is weighted from 2 to 10 points based on severity.

Question 8

Is the OFAC sanctions list updated in real-time?

Accepted Answer

Yes. Chainalysis screening queries the current OFAC SDN list on every scan. New Treasury additions, such as the 2022 Tornado Cash smart contract sanctions, appear in our results the same day. We do not cache the sanctions snapshot.

Question 9

Does the check detect Tornado Cash mixer usage?

Accepted Answer

Yes. Tornado Cash addresses are flagged under the Mixer risk factor (weight 6 points). The tool detects direct interaction with Tornado Cash contracts on Ethereum and L2s. Indirect interaction through several hops can also trigger the flag depending on cluster depth.

Question 10

Is travel rule (FATF) information included?

Accepted Answer

No. Travel rule data is exchanged between VASPs, not surfaced to the public. That data covers sender and recipient KYC details for transfers above local thresholds. Our tool flags addresses by on-chain behavior, not by counterparty KYC status.

Question 11

Can a clean wallet still get flagged (false positive)?

Accepted Answer

Rarely. False positives mostly happen with bridge contract addresses that briefly held flagged funds, fresh exchange hot wallets that just processed flagged user withdrawals, and DEX aggregator routers used by flagged actors among many legit users. If a counterparty wallet is flagged but the address is a known bridge or aggregator, the flag is usually benign.

Question 12

How does Lazarus Group (North Korea) attribution work?

Accepted Answer

Lazarus Group addresses are clustered through on-chain forensics. The starting point is funds from confirmed DPRK-controlled wallets announced by US Treasury and blockchain analytics firms. The cluster expands to addresses that received those funds within short hops. Chainalysis maintains the cluster and updates it as Treasury sanctions new wallets.

Question 13

How does the free check compare to AMLBot paid plans?

Accepted Answer

We use the same data sources as AMLBot Free plan, GoPlus Security plus Chainalysis Sanctions. Paid AMLBot plans add deeper transaction graph analysis, batch wallet scanning, API access for custodial integration, and Compliance officer reports. For one-off checks before P2P trades, the free tier covers the highest-weight risk categories.

Question 14

Can I check a Bitcoin address?

Accepted Answer

Bitcoin support depends on the data source. Sanctions screening works for Bitcoin via Chainalysis. The 18-factor GoPlus check is EVM and Solana focused, so Bitcoin gets only the sanctions list match. For full forensic Bitcoin analysis, see paid services like Crystal Blockchain or MistTrack.

Question 15

What do I do if an exchange freezes my deposit despite the address being clean?

Accepted Answer

File a support ticket with the exchange. Attach our wallet check report URL or screenshot, state your transaction hash, and request manual review. Most exchanges reverse the freeze when an independent AML check returns clean. Keep the report URL for at least 30 days.
