Accepting unchecked crypto can get your exchange account frozen. Paste a wallet address or a transaction hash and see the risk score, where the funds came from and any links to mixers, darknet markets or sanctioned entities.
First check free after sign-up. USDT on Tron, Ethereum and BNB Smart Chain, Bitcoin, Ethereum and other major coins.
A crypto AML check, also called KYT (Know Your Transaction), traces where the coins in an address or a transaction came from and scores how risky they are. Every source of funds falls into one of three groups: trusted, suspicious or dangerous.
If a large share comes from dangerous sources, exchanges and counterparties may refuse your funds, and your own wallet can be flagged as risky too. That is why it pays to check a wallet before you accept a transfer, not after.
Which sources count as dangerous?Tainted coins can cause trouble even if you did nothing wrong:
An exchange or a payment service may ask you to pass extra verification and prove where the funds came from.
Coins in your wallet may be treated as tainted, and exchanges or counterparties will refuse to accept them.
Your wallet may be blacklisted and the funds frozen until the review is over.
USDT is the most common coin in P2P deals and the most common reason for frozen accounts. The same token runs on several networks, and each network has its own addresses and its own history, so the check always runs on the network the transfer was made on.
Tron
The usual choice for P2P trades and OTC deals. Tron addresses start with T.
Ethereum
Common on exchanges and in DeFi. Addresses start with 0x.
BNB Smart Chain
Low-fee transfers. Addresses also start with 0x, so make sure you pick BNB Smart Chain, not Ethereum.
USDC is checked on the same three networks.
Ask the counterparty for the address they will send from, or copy the transaction hash (TXID) from your wallet. Paste it into the search bar, open the address or transaction page and press Check Address or Check Transaction. The report shows the share of funds from trusted, suspicious and dangerous sources.
Gives you a first impression of the transaction. The score is calculated from how much of the funds came from trusted, suspicious and dangerous sources: 0-30 is low risk, 31-69 is medium, 70-100 is high.

Dangerous sources:
0-30 · Low risk
In most cases the transfer is safe. Save the report anyway: it records the state of the address on the day you checked it.
31-69 · Medium risk
Open the sources breakdown. A share from unlicensed exchanges or crypto ATMs is common. Funds that came straight from a mixer or a darknet market are a different story. Decide by the sources, not by the number alone.
70-100 · High risk
Refuse the deal if you still can. If the coins are already in your wallet, contact your exchange support before depositing them and attach the report: it shows where the funds came from and the share linked to risky sources.

GetBlock.net uses a 0-100 scale: 0-30 is low risk, 31-69 is medium, 70-100 is high. Exchanges set their own limits, so even a medium score can lead to questions from compliance. Always look at which sources make up the score.
An address check covers the whole history of a wallet: where it receives funds from and who it deals with. A transaction check covers one transfer and shows exactly where those coins came from.
Yes, and that is the best time to do it. Ask the sender for their address before the transfer and check it first. Once the coins are in your wallet, you cannot send them back without a trace.
No. The score reflects what is known about the address at the moment of the check. Risk databases are updated all the time, so the same address can get a different score later.
No. KYC verifies a person's identity. An AML check (KYT) looks at the funds: where the coins came from and where they went. It does not reveal who owns the wallet.
Yes. Connect the crypto transaction monitoring API: send each deposit or withdrawal for screening and get the risk score and sources of funds in JSON. API access comes with the PRO and Maximum packages.
