The RPC connection is part of your privacy model
An Ethereum RPC provider receives chain queries from your wallet and may see account addresses, IP information, and request timing. Changing the provider changes who receives those requests; it does not hide public transactions.
Follow a request from wallet to server
Example: asking for an account balance
Your wallet asks an RPC server for data about an address. RPC means remote procedure call: one program asks another to do a task. The server returns the result. It may also see your IP address, which helps route internet traffic. This is separate from the transfers that everyone can see on Ethereum.
- Request: The wallet asks about an address.
- Recipient: The RPC service receives that request.
- Boundary: Changing the service changes who receives the request, not the public chain history.
Keep in mind: Check other data services too. Replacing the chain endpoint may not replace the wallet’s price or name services.
Evaluate a provider change
Write down which request you are moving
Start with one action, such as a balance lookup. Note which wallet setting selects its endpoint and which provider receives it. Then list separate features such as prices and name lookups. A custom chain endpoint may affect only the first request. Do not mark every wallet data flow as private because one setting changed.
Check what the policy actually covers
Look for an explanation of which request data is recorded, how long it is kept, and whether other services receive it. A missing retention period is an unanswered question, not evidence that nothing is stored. Record the uncertainty in your wallet privacy review. The provider’s policy and the public transaction record describe different kinds of exposure.
What can an RPC server see?
An RPC server can see what it was asked for and may see network metadata. Wallets use remote procedure calls to read the chain’s records and submit transactions. A balance lookup may name the account directly even when no transaction is broadcast.
Policies and architecture both matter
A provider’s retention rules describe how it says it handles data; its position in the request path determines what it can observe. Check both. A custom endpoint can change the observer without eliminating observation. A wallet may still use separate services for names, token lists, or price data.
Does running a node make transactions private?
No. Running a node does not hide the public transactions it broadcasts. A personal node can reduce reliance on a third party for chain queries. It requires maintenance, storage, and secure configuration. Exposing an unrestricted RPC endpoint to the internet creates security problems.
Minimize what you need to send
Prefer tools that can explain their data flows. Avoid entering addresses into unrelated websites just to obtain generic educational advice. Our wallet privacy checklist runs locally without an RPC connection because a habits review does not require your balance or transaction history.
