What Is a Stealth Address in Crypto?

A stealth address solves a specific privacy problem: it lets someone receive funds without publicly revealing which address on the blockchain actually belongs to them, generating a fresh, one-time address for each transaction instead of reusing the same visible address repeatedly.

Why Reused, Public Addresses Create a Privacy Problem

Repeatedly using the same wallet address means anyone can look up that single address and see the complete history of everything ever sent to or from it — publicly sharing an address once, for any purpose, permanently exposes that entire history to anyone who later looks it up.

What a Stealth Address Actually Does

Rather than sharing one fixed, reusable address, a stealth address system generates a unique, one-time address for each individual transaction, derived cryptographically from the recipient's actual keys — the sender can compute and use this one-time address without ever needing to know or interact with the recipient's real, underlying wallet address directly.

How the Recipient Still Accesses Funds Sent This Way

Even though each transaction goes to a different, unique address, the recipient's private keys allow them to detect and access funds sent to any of these one-time addresses — from the recipient's perspective, everything remains fully accessible and spendable, just not visibly linked together on the public ledger.

Why This Specifically Protects Against Public Observation

Someone observing the blockchain sees a series of seemingly unrelated, one-time addresses, each receiving a single transaction — without the recipient's private information, there's no way to determine that all of these separate addresses actually belong to the same person.

Why This Differs From Simply Generating a New Address Manually

Manually generating and sharing a new address for every transaction accomplishes something similar, but requires active effort and coordination with the sender each time — a stealth address system automates this process cryptographically, without requiring the recipient to manually generate and distribute a new address for every single incoming transaction.

Why Stealth Addresses Aren't Universally Implemented

This is a specific technical feature that needs to be built into a blockchain's protocol or wallet software — not every blockchain or wallet supports this capability, meaning its availability depends entirely on which specific network and tools you're using.

Why This Addresses a Different Problem Than a Mixer

A mixer obscures the connection between a specific deposit and withdrawal within a shared pool. A stealth address instead prevents the public linkage between multiple transactions received by the same recipient in the first place — related but distinct privacy mechanisms addressing different specific problems.

What This Means for Evaluating Privacy Features on a Specific Blockchain

Checking whether a specific blockchain or wallet you're using actually supports stealth addresses as a built-in feature, since this determines whether this particular protection is available to you without requiring a separate, additional privacy tool.

Check whether your wallet or blockchain supports stealth addresses — this feature prevents your receiving address history from being publicly linkable in the first place.
