Tornado Cash, a privacy Defi application for Ethereum, will also be available for Avalanche [AVAX]. For Blockchains like Ethereum and Avalanche, all transactions are public and applications like Tornado Cash help to avoid track your ETH.
Tornado Cash at Avalanche will be called Sherpa Cash and work like Tornado Cash. But usually for Avalanche, fees will be much lower, because right now, people pay up to 50$ for a Tornado Cash transaction, Avalanche is much cheaper.
Sherpa Cash will be live at Avalanche in a few weeks:
