Ethereum Transit Authority

Ethereum Transit Authority maps which outside services learn about a user's activity when sending ETH from different wallets, and states that even a self-run node still exposes some data. In the default MetaMask extension send, 12 requests reach Consensys services, Blockaid, Infura, Etherscan and Segment, including the user's IP address and the unsigned transaction. The Rabby send on v0.94.3 has 17 requests across 14 stations, mainly to Rabby's DeBank API, Hyperliquid, Etherscan and Google Analytics. Even the self-run node route still sends the signed transaction to builders and relays.
