Stealth Addresses: How They Protect Your Crypto Privacy

When working with stealth addresses, a technique that generates a unique, one‑time destination for every incoming payment. Also known as one‑time addresses, they keep the receiver’s real public key hidden while still allowing funds to be collected safely.

Key Concepts Behind Stealth Addresses

Stealth addresses rely on a cryptographic handshake between sender and receiver. The sender uses the receiver’s public view key and a random nonce to compute a new public key for that transaction only. This one‑time key appears on the blockchain, so observers can see the payment but can’t trace it back to the owner’s reusable address. The receiver, who holds the matching private view key, can scan the chain, spot the hidden payment, and spend it using the associated private spend key. In practice, this means each transfer looks like a fresh address, breaking the link between multiple payments and making analytics very hard.

One of the most famous projects that built stealth addresses into its core is Monero, a privacy‑first cryptocurrency that combines stealth addresses, ring signatures, and confidential transactions to hide sender, receiver, and amount. Monero’s implementation shows how the three techniques reinforce each other, creating a strong shield against blockchain surveillance.

Another pillar of privacy is ring signatures, a method where a transaction is signed by a group of possible signers, so observers cannot tell which member actually authorized the move. When paired with stealth addresses, ring signatures hide the source of funds while the one‑time address hides the destination. This double‑layered approach is why many privacy coins can claim true unlinkability.

To protect the transaction amount, many projects use confidential transactions, a cryptographic proof that validates the sum of inputs and outputs without revealing the actual values. Confidential transactions make it impossible to see how much was sent, adding a third dimension of secrecy. Together, stealth addresses, ring signatures, and confidential transactions form a privacy triangle that covers sender, receiver, and amount.

Beyond dedicated privacy coins, mainstream wallets are starting to adopt stealth address support. Some hardware wallets let users generate a new public key per payment, while certain DeFi platforms offer optional privacy layers that hide user balances. Mixing services also use similar ideas, funneling funds through multiple one‑time addresses to break the transaction trail. The result is a more private experience for anyone who wants to keep their financial activity off the public ledger.

Understanding how these building blocks fit together helps you decide whether to enable stealth addresses in your own crypto workflow. Whether you’re a casual holder looking to keep your purchases private or a developer building a privacy‑focused dApp, the concepts outlined above are essential.
