Addresses are pseudonyms, and public activity can reveal connections.
LET’S PICTURE IT
A notebook might use nicknames instead of names, yet repeated entries can still reveal who a nickname probably belongs to.

From a public address to a verified signatureStep 1 / 4
An address is public receiving information. It is not the private key that authorizes actions.
An address is public receiving information. It is not the private key that authorizes actions.The local signing system uses secret authorization material. It produces a signature; the private key is not sent along with it.A verifier checks the signed request under the account’s rules. A valid signature does not by itself prove that the action is safe.Balances belong to network state. A wallet is an interface and signing system, not a box containing coins.

Addresses are visible identifiers
Public Ethereumtransactions show account addresses and action data. An address does not contain a person’s name, but it gives observers a stable identifier they can follow across activity.
Connections can reveal context
If someone publicly posts a donation address or links it to a profile, observers can connect that statement with onchain activity. Services can also hold information that links accounts to people.
Data can remain visible
Do not put passwords, secret messages or personal information in public calldata. Even if an interface stops displaying it later, historical data can remain available from other sources. Ordinary encoding is not encryption.
Privacy needs deliberate design
Using a new address does not automatically erase links created by transfers or other behavior. Learn what your wallet shares and what a website can see. Our privacy note explains how this site treats your local inputs.

Does a hexadecimal address guarantee anonymity?
Addresses are pseudonymous. Public and external information can connect activity to identities.
