Stealth-address privacy for Nimiq holders

Every payment you receive lands at a fresh, one-time address that no on-chain observer can link to you, or to your other addresses. Wallet layer, no protocol change, proven on testnet.

Nimiq is fully transparent

Every balance and transaction is public. A holder's whole stash sits at addresses anyone can watch.

How it works

A fresh address every time

Every payment you receive lands at a fresh, one-time address that no on-chain observer can link to you or to your other addresses.

Your address stays off chain

You publish one meta-address. Senders use it to derive a one-time address per payment, so the address you share never appears on the chain itself.

No protocol change

Dual-key Ed25519, the same construction as Ethereum's ERC-5564, built on Nimiq's existing primitives. The announcement rides the standard transaction data field, so there is no new transaction type and no fork.

What it hides, and what it does not

It hides which addresses are yours, not how much or from whom. This is the Ethereum stealth-address class, receiver-unlinkability, not Monero or Zcash.

Hidden from an observer

  • Which addresses are yours
  • The links between your addresses
  • Your published address, which never lands on chain

Still visible to anyone

  • Amounts, every value is public
  • Who paid you, the sender
  • Your spends and any consolidation

Proven on testnet

One published address. Two senders paid it three times on Nimiq testnet. To a chain analyst the three payments look unrelated.

Without the view key

Three unrelated addresses. No way to tell they share a recipient.

With the view key

All three collapse to one recipient. Only the holder can do this.

Every transaction is real and resolves on test.nimiq.watch. This is testnet, no mainnet funds until an external audit passes.

Roadmap

Honest about where this stands. The cryptography is built and tested. A paid external audit is the gate before any mainnet funds.

  1. 1

    Testnet now

    Real payments, real block-scan discovery, real spends with the derived key. Backed by an independent adversarial crypto review.

  2. 2

    External security audit

    A professional third-party cryptography audit. This is the gate, and it is the line we hold before touching real funds.

  3. 3

    Mainnet

    Stealth receiving on Nimiq mainnet, once the audit passes and the anonymity set is meaningful.
