Bitcoin Forum

While I was searching for sanctioned addresses listed by authorities, I couldn’t find any direct or easy to use tool. So, I created this simple and user friendly tool using the free API provided by Scorechain. It’s completely free to use. Scorechain offers the API for free screening, but they don’t provide a direct search option, so I decided to build one myself.

Currently i have no reason to check whether an address is part of sanction. But i tried it a bit with few cryptocurrency address listed on US OFEC website and it seems to work properly.


It's good to see you decided to give open source license, although you may want to choose specific one (such as MIT license).

Hey, thanks for the heads-up, I will add the MIT license.

I also have no reason to use this tool, but I find it interesting to give access to this API in such a simple way. I’ve played around with it a bit by testing different addresses I found on the forum, some random ones and some known to be sanctioned by the OFAC. The tool seems to work very well at first glance.

Well done, OP! It’s always nice to see people creating tools that are easy to use and open source.

Honestly, its super refreshing when someone actually does something instead of just whining about whats missing.  You couldnt find a tool?  So you went ahead and made your own - hell yeah, thats the spirit.  Way too many folks just sit around waiting for someone else to fix things.  You spotted a gap and just jumped in.  Good job!

Thanks for testing it out, that made my day.


Thankyou.

There isn't one for a clear reason, if the sanctioned found out they are sanctioned they would use the tool to bypass that.

That's why companies like chainanalysis do not share that publicly and requires strict license/regulation for its API.

So a public one is completely useless in my opinion and unreliable.

I don't think so. I guess you have no idea how AML scores work. What we need to worry about is sanctioned money that the government has its eyes on. Yes, they can move coins to multiple accounts, use mixing, CoinJoin, and other services, but by doing so, the transaction becomes untraceable.

AML scores are purely unreliable because they don't share their source, and these APIs are publicly available, meaning anyone could avoid them. For additional security, you could use services like https://light.misttrack.io/ (https://light.misttrack.io/) that can help you out.

Here is an example AML report I got for the address: bc1qcatv4gxq24z8hwt67sftjlnlm6dxnk04saz5zw

I find this analysis unreliable because how can using a mixing service that protects user privacy be considered a high-risk activity? They even take mixing patterns as high-risk activity seriously?

By the way, this is the money that was seized from the eXch.cx wallet.

One problem I see with your service is that governments and exchanges are randomly adding and removing addresses from blacklist.
And we all know that any coins seized and sold by governments are automatically getting whitelisted.
I think you should add source link that confirms when bitcoin address was blacklisted and who did it.
Also think about adding link for news and updates when new addresses are added.

It's all just a security theater  :P
I think they are doing something similar with decentralized Coinjoin.

Hey, thanks for the suggestion, but I must disappoint you as I said these data aren't owned by me but by the scorechain as I mentioned on the thread and on my website, so I have no idea about the source, but I'm sure they are using latest data. https://sanctionslist.ofac.treas.gov/Home/SdnList (https://sanctionslist.ofac.treas.gov/Home/SdnList)

Does anyone know how quickly a newly sanctioned address gets added to the Scorechain database? I’ve twice tried to withdraw BTC from exchanges to addresses of a company that was sanctioned later - yet the exchanges seemed to know in advance and refused the withdrawals.
