Infura provides the decentralized nodes necessary to run crypto wallets. MetaMask, a popular Ethereum wallet, was launched in 2016. Both products are owned and operated in sync by ConsenSys.
MetaMask was designed to select Infura as its default transaction broadcaster. Remote call procedure technology (RPC) is used to connect the wallet to Infura. This means that users can send ERC tokens via MetaMask to Infura, and Infura links the transaction with Ethereum’s blockchain.
Infura retrieves and stores the IP address associated with MetaMask users in its off-chain data collection policy.
Privacy concerns raised by ConsenSys updates and Uniswap
According to the firm, it does not collect data from users who use other RPC service providers. Third-party RPC firms may have access to the same data.
While MetaMask founder Dan Finlay stated that the wallet does NOT collect IP data, users raised concerns about the privacy risks associated with such policies. Theoretically, IP data and on-chain data could be combined to track and dox individuals.
This can be fixed quickly, I believe. We don’t use IP addresses, even if they are temporarily stored. They aren’t needed as they aren’t being used for anything. – Dan Finlay (@danfinlay), November 24, 2022
