ConsenSys has revised the privacy policy of MetaMask, a popular self-custody wallet with over 21 million monthly active users. The updated version states that MetaMask will start collecting Ethereum wallet addresses and IP addresses during on-chain transactions.

ConsenSys explained that the data collection only applies when someone uses Infura, Mestamask’s default Remote Procedure Call (RPC) application. When users use a third-party RPC or their own Ethereum node, the new update to the privacy policy does not apply; they play by the rules of the RPC you are using.
