What your Ethereum wallet can reveal before you send anything
An Ethereum wallet can reveal account queries and connection data to outside services before you send a transaction. Review RPC settings, app connections, and token allowances separately; self-custody does not prevent all data sharing.
Trace one balance check
Your wallet may ask more than one service
Opening a wallet can start a chain of requests. One service may return a balance, another may supply a token price, and another may resolve a name. These are separate data flows. RPC metadata is the information around a chain request, such as which address was queried and when.
- Find the provider: Look for the network or RPC settings in your wallet.
- Read the policy: Check what the receiving service says it stores.
- Review the session: Look at connected sites and remove connections you no longer need.
Keep in mind: No transaction does not mean no data was sent. Reading a balance can still involve an outside service.
What can a wallet share before a transaction?
A wallet signs requests, but it often asks outside services for balances, prices, and transaction status. Those requests can reveal addresses and data about the connection to the receiving service. Read the wallet’s current privacy policy and RPC settings rather than assuming that self-custody means no data collection.
Does disconnecting a site remove its allowance?
Disconnecting an application does not by itself revoke a token allowance stored onchain. Review connected applications and remove sessions you no longer use. Treat session management and contract permissions as two separate tasks.
Keep secrets out of support channels
A legitimate troubleshooting process should not need your recovery phrase. Screenshots can also reveal balances, names, and addresses. Before sharing a diagnostic report, inspect what it contains. Never enter a secret into an online privacy checker, including a site claiming to evaluate your wallet.
Use a repeatable review
Check where updates come from, backup storage, RPC provider, telemetry preferences, connected sites, and token allowances. Our local privacy checklist helps organize this review without collecting a wallet address. It measures completed checks, not an anonymity score: no questionnaire can prove that your transactions are private.
