A transit map makes wallet data dependencies visible
Ethereum Transit Authority helps teams ask which companies receive information along a wallet journey.
Austin Griffith introduced a visualization of wallet data leakage on November 9. Ethereum Transit Authority presents wallet journeys as transit routes through services such as RPC providers, giving developers a way to examine dependencies beyond the signed transaction.
The project distinguishes live observations from code-traced or partly inferred routes. That distinction matters: a map can guide an investigation without proving that every depicted request was captured in a current session. Its evidence view makes those differences part of the reading experience.
For a wallet team, a useful review starts with the actual user journey: what information leaves, which provider receives it and what still leaves when a user chooses their own node. The visualization supports that inventory; it is not a blanket privacy certification for any wallet.
