What Is a Bitcoin Blender

Mixers, also known as tumblers, are essential tools for enhancing the privacy of cryptocurrency transactions. By obscuring the link between bitcoin addresses, they help users keep their financial activity private and safe from prying eyes.

Recently, the US Treasury imposed sanctions on Blender and Tornado Cash, two mixers that helped North Korean hackers launder millions of dollars in stolen crypto. However, a new mixer named Sinbad has sprung up to replace them.


Bitcoin mixers, also known as tumblers, help users enhance their privacy by breaking the link between the initial and final addresses of a crypto transaction. This makes it impossible for anyone to trace the flow of funds, thereby protecting users’ anonymity. While some governments and regulators have cracked down on mixing services, most users continue to use them for legitimate reasons.

Bitcoin mixers work by combining your coins with other coins that have already been sent to the mixer, then sending them back to your wallet in a random order. They can mix BTC, ETH, and LTC, making them ideal for users who want to keep their coins private but still transact with other blockchain-based digital currencies. Mixers can range from custodial to noncustodial, with the latter offering a greater degree of privacy for larger amounts.

While some US authorities have targeted mixers like Blender, many are still available. In 2022, for example, the US Treasury’s Office of Foreign Asset Control (OFAC) sanctioned a mixer called Tornado Cash. According to blockchain analysis firm Chainalysis, the mixer had been used by hackers from North Korea’s Lazarus Group to launder stolen bitcoin.

Despite this, cryptoasset exchanges and financial institutions should take proactive steps to identify and manage the sanctions risks associated with these services. Blockchain analytics solutions such as Elliptic Lens can identify transactions involving mixers and other obfuscating services, and block them from taking place – ensuring compliance with sanctions requirements.


Bitcoin mixers, also known as tumblers, are an important tool for enhancing the privacy and security of cryptocurrency users. They blur the links between transactions by introducing a web of addresses, making it difficult for anyone to trace them. This is a crucial function in this digital age, where financial transactions can be easily traced.

In October, the US Department of Treasury sanctioned Blender, a service that North Korean hackers used to launder stolen funds. Blockchain analysis firm Elliptic believes that a new mixer called “Sinbad” is likely a revival of Blender, based on its website structures, Russian-language support, and links with a wallet believed to be owned by Blender’s operators.


A bitcoin blender is a service that helps users protect their cryptocurrency transactions by obscuring their original source. It works by mixing your coins with other users’ coins and with previously cleaned Bitcoins in the mixer’s reserve. Once the process is complete, your cleaned coins are sent back to you. Its services are completely free and its operations are secure, which makes it a great option for people who want to keep their transactions private.

Bitcoin blenders can be categorized into two categories: decentralized and centralized. Centralized mixers are run by a single provider and have the advantage of being easy to use. They also offer excellent customer support. However, they come with a downside: the provider has access to the data of the transaction.

In order to use a bitcoin blender, you will need to create an account with the mixer and deposit your coins into its pool. After a certain amount of time, the coins are mixed and returned to your new second transition address. Traders can choose the location of their new bitcoin wallet, the period of mixing, and the amount they wish to blend.

The site offers a variety of features for its users, including an automatic withdrawal feature and the ability to delete their journal. The site also charges a small fee for its services, but it is among the lowest in the field.


In this digital age where financial transactions can be traced easily, bitcoin mixers (also known as tumblers) play a vital role in preserving the anonymity of users. They work by obscuring the link between the sender and receiver of coins through a series of additional transactions, making it difficult for tracers to follow the flow of your coins. You will need to transfer your bitcoins to a new blending address from the initial transition wallet, choose a period for mixing and select a destination wallet for the resulting bitcoins. The cost of this service varies, with centralized mixers charging more than decentralized ones. The United States has sanctioned the Bitcoin mixing service Blender for allegedly helping North Korean hackers launder $20.5 million stolen from the Axie Infinity hack in March.
