Let’s start with understanding the rise of tornado cash alternatives.
For the Unversed: Tornado Cash in a Nutshell
Table of Contents
Tornado Cash, an Ethereum-based DApp, facilitates the anonymous movement of crypto assets between wallets using smart contracts deployed in 2019. These contracts power individual pools where users deposit crypto, generating unique proofs of deposit for withdrawal.
Utilizing zk-SNARK technology, Tornado Cash ensures anonymity by unlinking depositing, and withdrawing wallets, without mixing cryptocurrencies. Importantly, the protocol is non-custodial, with users retaining sole access to their assets throughout the process.
Tornado Cash Faces U.S. Government Sanctions
In August 2022, the U.S. Treasury’s Office of Foreign Asset Control (OFAC) sanctioned Tornado Cash, citing inadequate anti-money laundering (AML) practices and risk management protocols. The announcement blacklisted numerous Tornado Cash smart-contract wallet addresses, prohibiting U.S. citizens and entities from engaging with the protocol.
Violators face severe penalties, including fines and up to 30 years in jail. OFAC alleges that Tornado Cash has facilitated the laundering of over $7 billion in illicit funds since its 2019 launch, including notable cyber heists. The crackdown has sparked controversy, with critics arguing it infringes on privacy rights.

As we are done understanding the backdrop, below are a few alternatives.
Exploring Tornado Cash Alternatives
UniJoin
UniJoin distinguishes itself as a crypto-mixing service focused on enhancing anonymity in cryptocurrency transactions through its CoinJoin technology.
Unlike zk-SNARK applications, UniJoin may yield different tokens from the ones initially deposited, offering an alternative to services like Tornado Cash.
Its user-friendly platform allows for seamless anonymous crypto activities, including storing untraceable coins, making purchases, and sending crypto, with options for scheduling delayed transactions to enhance privacy.
Despite these advantages, UniJoin operates centrally and temporarily holds users’ assets during mixing, unlike Tornado Cash’s decentralized and custody-free approach.
Coinomize
Coinomize, a Bitcoin mixer, operates similarly to UniJoin by employing CoinJoin technology to ensure user anonymity on the Bitcoin blockchain.
Like UniJoin, Coinomize boasts 100% anonymity, with no logs or user data stored post-mixing, and allows users to customize transaction delays for enhanced privacy.
Additionally, Coinomize permits anonymous crypto transfers to up to five different addresses and offers fee customization options, with increased fees and longer mixing times purportedly enhancing anonymity.
However, Coinomize has its drawbacks, including a minimum transaction amount of 0.0015 BTC per added output address, and its exclusive focus on Bitcoin, lacking the versatility of UniJoin. Additionally, Coinomize, like UniJoin, operates centrally and temporarily holds users’ assets during mixing, deviating from Tornado Cash’s decentralized approach.
MixBTC
MixBTC provides a user-friendly Bitcoin mixing service, akin to Coinomize and UniJoin, allowing users to anonymize their transactions effortlessly.
Its intuitive interface simplifies the process, requiring users to input their Bitcoin wallet address, specify the desired service fee, and schedule a transaction delay to enhance anonymity.
Despite its simplicity, MixBTC is limited to Bitcoin transactions, offering little utility for users of other cryptocurrencies. Like UniJoin and Coinomize, MixBTC operates as a centralized entity, and during the mixing process, it takes custody of users’ crypto assets, unlike Tornado Cash, where users retain control throughout.
0xMonero
0xMonero (0xMR) emerged as a privacy-centric ERC-20 token launched in 2020 on the Ethereum blockchain. It aims to overcome Monero’s limitations by introducing a capped token supply and Ethereum compatibility.
With its capped supply of 18.4 million tokens and Ethereum compatibility, 0xMonero offers enhanced usability and accessibility compared to Monero.
The fair launch without pre-mining ensures regulatory compliance, reducing the risk of classification as a security asset. Operating as a decentralized smart contract on Ethereum, 0xMonero provides resilience against external interference.
However, its limited recognition and adoption, along with the necessity for specific 0xMR transactions for privacy, pose challenges to widespread adoption.
Cyclone Protocol
Cyclone Protocol stands out as a versatile, decentralized privacy-preserving solution, leveraging zk-SNARK cryptography to unlink deposit and recipient addresses.
Initially launched on the IoTeX blockchain, Cyclone now extends its reach to Ethereum, BNB Chain, and other EVM-compatible blockchains. Similar to Tornado Cash, Cyclone ensures users retain custody of their assets throughout the transaction process.
With its foundation rooted in Tornado Cash’s code, Cyclone Protocol offers a familiar alternative for users seeking similar privacy features. Notably, it boasts cross-chain functionality, enabling seamless transactions across multiple major blockchains.
Governed by a Decentralized Autonomous Organization (DAO) on the IoTeX blockchain, Cyclone Protocol ensures decentralized governance and decision-making. However, despite its audited code, Cyclone Protocol acknowledges the inherent risks associated with experimental software.
Users are cautioned to exercise caution when using the protocol, as it cannot guarantee flawless execution of its smart contracts. Despite this, Cyclone Protocol remains a promising privacy solution for those willing to embrace its innovative approach
Messier 87
Messier 87 is at the forefront of developing crypto and DeFi applications across major blockchains, aiming to drive public adoption of DeFi by offering a wide array of decentralized tools for businesses and consumers to transition from fiat to cryptocurrencies.
Their flagship application, “Horizon,” offers decentralized anonymous payments based on zk-SNARK technology, ensuring transaction privacy. Despite its reliance on Tornado Cash’s code, Messier 87 is rebuilding Horizon to mitigate recent sanctions and enhance its security features to combat illicit activities effectively.
Horizon enables users to send cryptocurrencies without public visibility, supporting various tokens like ETH, USDC, and more.
With plans for multi-chain functionality, Horizon’s usability is set to expand across different blockchains, offering greater accessibility beyond Ethereum. Importantly, the application’s blockchain-based smart contract model ensures a non-custodial process, preserving users’ control over their assets without the need for third-party custody.
