Mixing services enable users to send their cryptocurrencies into a pool, where the funds are mixed with others before being sent back to the user. This process makes it difficult to trace the original source of the funds, thus providing privacy for users' transactions. Mixers operate on various blockchains and can be used to mix different cryptocurrencies. The process usually involves sending the cryptocurrency to the mixing service, which then sends back the same number of coins, but from a different wallet address. This operation can include multiple users, making it more challenging to link transactions to individual wallets.
