How to create a Nimiq wallet: Nimiq Pay, Nimiq Wallet, and Keyguard

Last updated Written by the ImpactZero validator team

In short

Nimiq Pay is the mobile app, the Nimiq Wallet at wallet.nimiq.com is the browser interface, and Keyguard is the component that holds your keys and signs with them. They are layers of one system rather than competing wallets. Create the account in a browser, then back it up.

Three names, one account

The first thing to get straight is that you are not choosing between wallets. Search results treat Nimiq Pay, the Nimiq Wallet and Keyguard as competitors, and they are not: they are layers of one system, and most people end up using more than one of them with the same account.

What each piece actually is:

Piece What it is Where it runs
Your account A key, and the addresses derived from it. This is the thing that owns NIM. Wherever you keep it
Keyguard The component that stores the key and signs with it. Never shows it to anyone. Its own isolated origin inside your browser
Nimiq Wallet The interface: balances, sending, receiving, staking. A browser tab at wallet.nimiq.com
Nimiq Pay The same account carried on a phone, built around payments. A native app, keys held on the device
Nimiq Hub The doorway other websites use to ask your wallet for a signature. hub.nimiq.com, usually as a small popup

So "which Nimiq wallet should I use" is really two smaller questions. Where do you want to transact, and where is your key. Answer the second one carefully and the first one stops mattering much.

Creating an account in the browser

The browser route is the canonical one. Open wallet.nimiq.com and choose to create an account. Nimiq's own litepaper describes this as three clicks, with no downloads and no personal data, and that is the part worth pausing on: there is no email to confirm, no phone number, no identity check and no application to approve. A key pair is generated on your machine, and that is the account.

What you come out with:

  • An address. Nimiq addresses start with NQ and are printed in blocks of four characters, which makes them far easier to check by eye than an unbroken string.
  • A password you chose. It encrypts the key in local storage. It is not a login to a service, because there is no service, so it cannot be reset by anyone.
  • A prompt to save a backup. Take it. The wallet will let you carry on without one, which is a reasonable choice for a first look at an empty account and a bad one the moment there is anything in it.

Nothing has touched the chain yet. Per the developer documentation, a basic account is created on chain when NIM is first sent to it, so until somebody funds it your address is simply a key you hold. You can add more addresses under the same account later, and an account can also be a Ledger hardware wallet rather than a browser key.

What Keyguard is, and why it sits apart

Keyguard is the piece nobody chooses and everybody uses. It is not an app you install or a wallet you sign up for: it is the part of Nimiq that holds private keys and performs signatures, and it runs on a separate, isolated origin so that no page can read what it stores. The litepaper puts it plainly, describing keys held locally and fully encrypted in private browser storage, on their own secure origin, isolated from other websites.

The developer documentation draws the same line as a trust boundary: the requesting application is untrusted, the Hub is semi trusted, and Keyguard is the only fully trusted component. Even a backup export runs inside Keyguard, so the app that triggered it never receives your recovery words. It is not being polite about it. It structurally cannot see them.

Two practical consequences for you. First, when a website asks you to sign something with Nimiq, the window that appears is drawn by Nimiq's code and not by that website, so the address, the amount and the recipient you are approving are reported by the trusted layer. Check them there. Second, a site can be compromised without your key being compromised, which is exactly the property the separation exists to buy.

Putting the account on a phone: Nimiq Pay

Nimiq Pay is the mobile half of the same story: a self custodial payments app published by Nimiq Labs, holding the keys on the device rather than on a server. Nimiq's Nimiq Pay page describes connecting your Nimiq Wallet to the app, which is the relationship in one line: it is your account, on your phone, in an interface built for paying rather than for administration. Its App Store listing named NIM, BTC Lightning and USDT on Polygon when we read it on 14 September 2026, while Nimiq's own page still describes parts of that as arriving, so treat the asset list as something to check rather than something to quote.

The custody model inside the app matches the browser one. Mini apps that run inside Nimiq Pay talk to the wallet through a provider, and the documentation for them is explicit that the wallet performs every cryptographic operation, that keys never leave it, and that the user approves each sensitive action in a native dialog. A mini app cannot read your key any more than a website can read Keyguard's.

Nimiq Pay is also how a phone signs for sites like this one. When you open our stake dialog on a desktop it goes through the Nimiq Hub; on a phone it goes through Nimiq Pay. Either way the signature happens in the wallet, and we never see a key.

Self custodial, stated without the marketing

Both interfaces are self custodial, which is usually sold as a feature and is better understood as a trade. You get three things:

  • Nobody can freeze the account, because nobody else holds it.
  • Nobody can spend from it, for the same reason.
  • Nobody needs to approve you having one. There is no application and no gatekeeper.

And you take on one thing: there is no recovery desk. No password reset, no support ticket, no identity check that restores access. If the key is gone and the backup is gone, the NIM is unreachable, and that is not a policy anyone can make an exception to. This is the entire reason the next section exists.

The first four things to do with a new account

  1. Make a backup and put it somewhere offline. Nimiq offers more than one way to do it, including recovery words, an encrypted login file and the newer backup codes, and we will compare them properly in a later guide. Whichever you use: write it down or store it away from the device, never type recovery words into a website, never photograph them, and never send them to anyone. No legitimate person will ever ask for them. Not Nimiq support, not a validator, not us.
  2. Label the account and the address. Labels live in your own interface and cost nothing, and they are what stops you sending to the wrong one of your own addresses later.
  3. Move a small amount first. Send a little NIM in, send some back out, and watch it confirm. Learning the flow on an amount you do not mind is cheap practice, and it verifies your address really is yours before anything larger arrives.
  4. Then, if you want to, stake. Staking is on chain delegation and keeps the NIM under your own key, so it is a reasonable next step once the backup is done. The walkthrough is in how to stake NIM.

So which one should you use?

Pick by where you actually transact. If you are at a desk, managing an account, staking or checking history, the browser wallet is the fuller interface. If you are paying someone in a shop or splitting a bill, that is the phone. Most people who use Nimiq for a while end up with both, which is fine, because underneath them it is one account and one key.

If you got here before the chain itself made sense, start with what Nimiq is. Everything else we have written for newcomers is on the Learn hub.

Questions people ask

Do I need to download anything to create a Nimiq wallet?
No. The Nimiq Wallet opens at wallet.nimiq.com in an ordinary browser tab, and the Nimiq litepaper describes new users creating an account in three clicks with no downloads and no personal data. There is no email address to confirm and no identity check. If you would rather keep the account on a phone, Nimiq Pay is a native app you install from the usual stores.
Is Nimiq Pay a different wallet from the Nimiq Wallet?
They are different interfaces to the same kind of account. Nimiq Pay is the payments app on a phone and the Nimiq Wallet is the full interface in a browser, and Nimiq's own Nimiq Pay page tells you to connect your Nimiq Wallet to the app. Both are self custodial, so in each case the keys stay with you rather than with Nimiq.
What is Keyguard, and do I have to install it?
Keyguard is the part of Nimiq that stores your private keys and signs with them, and there is nothing to install. It runs on its own isolated origin inside the browser, keeps keys encrypted with your password, and never hands them to the page that asked for a signature. The Nimiq developer documentation treats the requesting app as untrusted and Keyguard as the only fully trusted piece.
Can I use one account in both the browser wallet and the app?
Yes, that is the normal arrangement, and it is what Nimiq's Nimiq Pay page describes when it says to connect your Nimiq Wallet to the app. The account is a key, not a login, so whichever interface holds that key can use it. What travels between them is your own backup, which is why the backup has to exist before you need it.
What happens if I lose my password or my backup?
There is no reset and no support route that can restore an account for you. That is what self custodial means in practice. While you still have access, you can export a fresh backup from inside the wallet at any time, and doing that is much easier than explaining later why it was not done. Nobody at Nimiq, and nobody here, will ever ask you for your recovery words.
Does creating an account cost anything, or show up on chain?
Creating one costs nothing. A Nimiq address is generated locally, and the developer documentation notes that a basic account comes into existence on chain when NIM is first sent to it, so an unfunded address is simply a key you hold. You can make as many addresses as you like under one account and nothing is charged for holding them.
