Mixers or mixing services are platforms that can obfuscate the origin of cryptocurrency funds.

The aim is to make transactions anonymous and difficult to trace. To do so, the mixer will mix coins with others and send them to different wallet addresses.

Some users can use mixers to hide large transactions or avoid hackers. Criminals can also use mixers to launder illicit cryptocurrency funds. This is why they can be risky in terms of money laundering and terrorism financing.
