Below are six real wallet checks. We picked them on purpose so you can see what "looks fine" and "looks bad" look like, side by side. Each one has its own link you can copy and send to a friend, or to your exchange.
First time hearing words like "mixer" or "sanctions list"? That's normal. There's a short plain-English glossary on the FAQ page.
Belongs to a real, named person — one of Ethereum's founders. Nothing weird in the wallet's history. The kind of address an exchange almost never asks twice about.
One of the wallets a major exchange uses to move customer money. Boring traffic in and out, all day. Even four steps away, nothing nearby looks bad.
An over-the-counter shop that swaps crypto for cash. About 2 million USDT a day, but no license we could verify. One step away from an exchange that lost its license last year.
An ordinary user. Their funds sat frozen on Bybit for 11 days. The reason: this wallet had touched two old mixer contracts (services that hide where coins came from). The money was eventually released — but it cost two weeks and a lot of paperwork.
Part of Tornado Cash — a service that mixes coins so you can't trace them. The US Treasury added it to the sanctions list in August 2022. Most major exchanges hold or refuse anything that touched it.
Tied to a state-backed hacking group. On the official US sanctions list since March 2024. If anything from this address lands on your account, expect your bank or exchange to hold it and start asking questions.
Every exchange has its own rules and the final call is theirs, not ours. This is the pattern we see most often — your exchange may behave differently.
Important: a low score is not a green light. We don't decide for the exchange, and we can't promise any specific outcome — we just show you what an exchange's compliance team would also see.
First check is free, no signup. Paste an address — you'll get a report just like the ones above.
