web3privacy now
Web3privacy now is a research project aimed at discovering, highlighting, and analyzing privacy-preservation services and startups within the Web3 space.
⚠️ Note! Highlighted projects facilitate a different approach to privacy. Their solutions maturity varies from conceptualisation to mainnet. So use them cautiously, especially when projects don't have a third-party security audit. That's why Web3Privacy Now is ongoing research: aggregation (we are here now) - audit - scoring.
Feel free to update the list!
