Decentralized exchange (DEX) Uniswap's recently updated privacy policy appears to have attracted the ire of some members of the community, with concerns that collecting and storing user data works against crypto's core values.
This privacy policy, which was last updated on Nov. 17 reveals that the exchange collects publicly-available blockchain data, information about user devices such as browser information, and operating systems, and information about users’ interactions with its service providers, among others.
The team behind privacy-preserving cryptocurrency Firo argued in a Nov. 21 Twitter post to its 83,700 followers that Uniswap’s privacy update sets a “dangerous precedent” for DEXs: While we have the utmost respect in what @Uniswap has built, we strongly reject the incorporation of data collection to track user behaviour and onchain activity.
This sets a dangerous precedent for DEXes.
"We were contacted [...] by an infrastructure provider once who asked about our backend and what info we kept we were shocked by the question. '
Binance, OKX, KuCoin and a host of other exchanges also plan on doing the same.
