It's not good for privacy to exhaust the mixer's stash all by yourself. Luckily, for most real scenarios that won't happen.


I would expect they use random times. And because "chips" can be created by anyone who sends funds to new addresses with value 0.001 (or 2^N times more) each, you can't be sure where it came from just from observing blockchain evidence.

Based on chipmixer's response times, they likely only refill chips every day at most.

There are specific chips they often like to split into smaller ones too and it's possible there's an algorithm running thst does this task (that the admin can just look over, eg dumping the raw output so it can be imported into a wallet).

Mixers work by having many users use them at once so one user is harder to trace. It's why the recommendation for privacy from chipmixer themselves is about a week (before moving funds out of mixed addresses or vouchers). Based on the support queries we have here, there are lots of people mixing 0.1btc+ - even if that was just an example - so it should be quite difficult to trace (especially if splitting is used or other  strategies like merging vouchers).

I've got some questions. Let's say that they (ChipMixer) have the following funded addresses before they announce their service:

• 100 x 0.001 BTC
• 50 x 0.002 BTC
• 25 x 0.004 BTC
• 12 x 0.008 BTC
• 6 x 0.016 BTC
• 3 x 0.032 BTC
• 1 x 0.064 BTC

And assume that someone wants to mix 0.1 BTC by receiving a hundred of 0.001 BTC chips. How will they refill those 0.001 chips without looking suspicious? Will they split some of the 0.002 and some of the 0.004? Would it be better if they split from the deposited ones?

According to this post;

I conclude that there's no reason to mix more than 1 BTC using 0.512 or 0.256 chips, but rather hundreds of 0.001 & 0.002 chips unless you put the transaction fees above your privacy. It's much easier for a chain analysis company to search among 100-500 addresses than from hundreds of thousands.

Another;

Does that mean that you already have 0.5 & 1 BTC chips or that you'll split your weird looking 1.024 & 0.512 to 1 and 0.5? If it's the latter, isn't is meaningless?

This service is different than the rest due to this chip feature, which is, essentially, funds deposited prior your decision to mix coins. This means that it's time which makes it hard to trace. If you knew that I wanted to mix within a certain chronological period, you could exclude lots of transactions to detect who's the mixer.

I just don't understand how you know when it's the perfect time to create new chips.

When chipmixer rolled out the new v3 onion site they mentioned that it supports Segwit addresses but the chips may or may not be issued with segwit keys.


I imagine they had a lot of chips locked in legacy keys and it would take some time before they're depleted.  It's probably luck of the draw until that happens.

I wouldn't count on it.  I don't know for sure, but I suspect chipmixer is mining bitcoin including their own transactions.  With bitcoin the way it is, and considering how successful chipmixer has been, I doubt they're going start dealing in some shitty alt coin.

Is the actual page you need, you can go to https://github.com/Kimbatt/btc-address-generator to download the files and run then offline.
--> I have used this on and off for the last few months to test things but I have not verified / check the code at all so make 100% sure you are 100% offline when using it and purge everything from your browser when done.


The other option is to run electrum while offline and import the key, you should see the address. Then shutdown electrum and delete the wallet.

Have you used old Tor v2 version that is now obsolete and it's not using Segwit, or new Tor v3 with new segwit addresses?
I just checked that old version website of chipmixer is still opening with warning message that it will soon become obsolete.

is chipmixer doesnt have platfrom for mixing altcoin like tornado cash have? i think would be great idea since to add some altcoin since chipmixer has already gain good reputation

Which one the v2 or the v3 onion link?


How long? do you still remember when? what is the exact date?

Because right now you can't able to use their v2 onion link and non-segwit is currently disabled. If you start mixing they will give you a warning and lead you to v3 onion link.

In that case, you used the fake CM site, because if you read a few posts above, you can see that CM no longer uses legacy addresses regardless of whether you used Tor or not. You can check all this if you look at the first post on this topic or click on the signatures of one of the members of their signature campaign.

Can you post the link you used, and did you use a search engine for that?

Concur with the above. There are a couple of websites I know which will spit out segwit addresses if you feed them private keys, but I've not examined the code thoroughly enough on any of them to feel comfortable recommending them. Easier and safer to use Electrum.

For the record: this also works offline. You can also use Tails to run it from Live DVD through Tor.

Use this prefix when importing Segwit private keys into Electrum:

When you start mixing there is a clear notice that new Segwit is now used in Chipmixer so you can't expect to get coins on legacy anymore by default.
Easiest way is to use Electrum wallet for importing private key and I would suggest that, but I saw some people are using open source offline version of segwitaddress.org for generating segwit addresses from priv keys, however I can't vouch for this so you it at your own risk.

Chipmixer has abandoned legacy addresses since July 2021, it only gives you the private keys for the SegWit native addresses.

Is there a specific reason you want it to be a javascript html page? Why don't you just import them into Electrum? If you really want them to be legacy, you can just import the private keys as p2wpkh, generate a legacy wallet and send them there, which you can then check from brainwalletx.

Check this library maybe?

I checked the balance on the private key (the one with the smallest amount), 0 BTC, address never used. Then I checked it based on it's legacy public address, again 0 BTC.

I haven't checked the segwit address because I have no way to get the segwit public wallet from a private key.
To get the legacy public wallet from the private key I used the old brainwallet javascript web site. Know of any javascript sites that work offline to calculate the segwit address from the private key?

Did you check the segwit addresses?

I deposited over $10k in chipmixer over the onion url (chipmixorflykuxu56uxy7gf5o6ggig7xru7dnihc4fm4cxqsc63e6id.onion) on a very secure PC and clicked on withdraw. I was given a list of the private keys as usual with the amounts associated with each. Then when I checked the public addresses of the private keys on the blockchain, each wallet had 0 BTC and no incoming and no outgoing transactions.

This has never happened before after using the service dozens of times.

Chipmixer, is there a problem? Where's my BTC?

Issue resolved, thanks

Any amount under 1 mBTC is auto donated. If you deposit another 0.048 mBTC your total deposit is 1 mBTC and you will receive 1 mBTC chip.

Tor version is better protected than clearnet. We should avoid clearnet version.

We assume server content was not affected. If it was then attacker would take our SSL certificate instead of creating new one.
We do not know full story. It is also possible that DNS records were attacked to point at different IP.

Support isn't online 24/7, it may take up to a few days.

You can't withdraw less than 0.001BTC from ChipMixer. That's why, on step 1: Deposit, it shows:
