Ethereum privacy guide library
Start with what Ethereum makes public, then review wallet habits and privacy technology. This library groups the guides by those tasks so you can follow the question that matters to you.
Find the privacy question that matters to you
Start with exposure, then review your habits
To learn what strangers can see, start with Ethereum’s public record. If you already know the basics, use the wallet guides to check data sharing, permissions, and backups. The technology guides explain what each privacy method can and cannot hide.
You can read in any order. Each guide explains one question and links to the next concept when it helps.
Ethereum is public. Your identity is the missing piece.
Learn why Ethereum is pseudonymous rather than anonymous, what an address reveals, and how names and public profiles can connect activity to a person.
Build a privacy threat model before picking tools
Build an Ethereum privacy threat model around the observer, exposed information, practical precautions, and the limitations that remain.
Address reuse and ENS can turn separate moments into a profile
Understand how Ethereum address reuse, public ENS names, and repeated payments can connect activity to an identity.
What your Ethereum wallet can reveal before you send anything
See what an Ethereum wallet can reveal through RPC requests, connected apps, and telemetry. Learn which settings and permissions to review separately.
Token approvals: disconnecting a dapp does not revoke its allowance
Understand Ethereum token approvals, how allowances differ from dapp connections, and why disconnecting a site does not remove its spending permission.
Recovery phrase security: private, recoverable backups
Protect Ethereum wallet recovery phrases against theft and accidental copies while keeping backups usable for restoring access.
Zero knowledge is a proof property, not a privacy guarantee
Understand what zero-knowledge proofs can hide and why public inputs, account identities, and application metadata can still reveal information.
The RPC connection is part of your privacy model
Learn how Ethereum RPC requests expose account queries and connection data to a provider, and what changing an endpoint or running a node can change.
Stealth addresses: private receiving, with caveats
Understand how Ethereum stealth addresses create fresh payment destinations, why later spending can reveal links, and what to check about recovery.
