MetaMask: Add SwissLedger and Import the NOKU Token

Noku.io — Mon, 01 Jun 2026 15:46:46 GMT

A step-by-step guide to adding SwissLedger to MetaMask and viewing NOKU on the same network.

What You’ll Get

The SwissLedger network will be available in the MetaMask network selector.
You’ll be able to manually import an ERC20 token and see it in your wallet.

Requirements: MetaMask installed, wallet unlocked, active internet connection.

Why SwissLedger: From Nokuchain to SwissLedger

Since 2016, the Noku ecosystem has grown on Nokuchain, the proprietary blockchain that powered multi-chain wallets, swaps, bridges, staking, and on-chain gaming. As Noku evolves into a universal value transfer protocol (Noku One), the NOKU token is migrating to SwissLedger, the institutional-grade Swiss blockchain built by Noku.

What this means in practice:

Nokuchain was the foundation of the consumer products (wallet and gaming), which were discontinued at the end of May 2026. Nokuchain is the only part that is being retired.
SwissLedger is the new enterprise, permissioned, and compliance-aware network, designed for financial and institutional applications. It becomes the “home” of the NOKU token, where it will serve as the native settlement and utility asset. The official NOKU contract on SwissLedger is0x4D37f954B14dC43791fF7261Dc55Fc6322133443.
The NOKU contracts on Ethereum, BNB Chain, and Fantom remain valid and official. They are not affected by the Nokuchain retirement, and you can keep holding and using NOKU on those chains. SwissLedger adds a new home for the token going forward. For up-to-date details on utility and migration mechanics, always refer to noku.io/#token.

Adding the SwissLedger network in MetaMask, as explained below, is the first step toward interacting with the token on the new blockchain.

Network Details (To Copy)

Use exactly these values. If MetaMask shows warnings about the name or symbol, make sure the data matches the table before saving.

Click Save.

Step 8 — Activate SwissLedger

Go back to the MetaMask home screen
Open the network selector at the top
Under the Custom section, selectSwissLedger

The active network in MetaMask should display SwissLedger. If you see another network, repeat this step before importing tokens.

Part 2 — Import an ERC20 Token

Important: complete this part only with SwissLedger already selected.

Step 9 — Open Import Tokens

On the Tokens tab, click the three dots (⋮)
Select Import tokens

Step 10 — Enter the Contract

In the Token contract address field, paste the token’s official address.

For NOKU on SwissLedger, use the official contract address:0x4D37f954B14dC43791fF7261Dc55Fc6322133443
For more migration details: see the data published on noku.io/#token.
For other tokens: use only the address provided by official sources (project website, documentation, team).

MetaMask usually fills in Symbol and Decimals automatically. If it doesn’t, enter the token’s official values (e.g., NOKU: symbol NOKU, decimals 18 - always verify on the official page).

Click Next.

Step 11 — Confirm

Check the summary:

correct contract address
correct symbol
correct decimals

Click Import. The token will appear in the SwissLedger token list.

Common Issues

IssueWhat to do

MetaMask reports an “unknown network” or suspicious data

Compare each field with the table at the top. Do not save if the RPC or Chain ID are different.

The token doesn’t appear

Make sure you are on SwissLedger, not Ethereum or another network.

Empty symbol/decimals

Enter them manually using the token’s official data.

Transaction not visible

Check the address on explorer.ledger.swiss.

Security

Only import tokens whose official contract address you know.
Do not use addresses received via DMs, Telegram groups, or unverified emails.
Before sending funds, always make sure the active network is SwissLedger.

We already anticipated here this update of Crypto Heroes, which brought a lot of exciting contents, and today we want togive you a full overview of the cards you can find in the new pack!

These innovative additions will surely captivate your attention, as we wanted to add a layer of strategy to our gameplay.
Let’s dive into the details of each new card type:

N Cards — Empowering the INVESTORS: The N cards cater to a distinct playstyle, designed for strategic deck balancing and management. As the name suggests, these cards are related to ideal Investors, enabling them to help you while constructing your deck. With a lower weight, in some case even lower than 0, the N cards offer flexibility and allow players to fine-tune their strategies while maintaining equilibrium.

J Cards — A Touch of JOLLY: we wanted to focus on this very unpredictable moment of the market, adding some JOLLY cards that can be pretty useful if you can catch the high/low moments. Have a look at their perks and start to imagine how many new strategies you can have by combining them.

As you can see they are all mixed cards and those from this expansion give the exact sum of the cryptocurrencies they are related to, differently from the previous ones that gave the average score.

C Cards — We are nostalgic, we love the old fashion. That’s why we decided to add a couple of “regular” cards, from the classic series.

Crypto Heroes — Black Mana

Dear Noku Fam, things are getting bigger and bigger.
Crypto Heroes is about to take things to a whole new level, as stated in our previous article a lot of things are about to change and this is our first big update: BLACK MANA.

There will be two main game-modes in Crypto Heroes: for the main tournaments it’ll be possible to deploy only a certain set of selected “classic” cards, plus all the cards from the current expansion, in this case it will be: BLACK MANA.

Here you can find a full list of the available cards in the new game mode, obviously the Heroes cards can be used:
https://noku.page.link/available-cards

What happens to the other cards? No worries, the cards from the previous editions will still be “legit”, because we will regularly host special matches/tournaments called Wild, where all the cards are allowed!
Now we can have a deeper look at the new cards, shall we?

First of all, by checking the store you’ll be able to notice a dedicated pack.
There you can find the cards from the new expansion, and you should notice something very important: the mixed cards now give the exact sum of the cryptocurrencies they are related to, differently from the previous ones that gave the average score. This is a huge improvement, now if you play BTC + ETH you get the sum, not the average, and this makes the new cards extremely powerful!

That’s not all, though! We’re also introducing some powerful JOLLY cards. Trust me, these cards are a game-changer. They’re designed for those of you who know how to read the market like a true Hero.
We can’t wait for you guys to find out what are the perks of PANIC SELL.
It’s gonna blow your mind!

Alright guys this is it for today, we look forward to see your feedback about this new set of cards and we hope you’ll enjoy them.

The first steps of this revolution start from a new series of Prediction Games, which will be available effective immediately!
We kept some of the old pools but we added new ones, and you’ll be happy to see that a few of them have a guaranteed prize!

Noku — Notification Center

Exciting news, Noku fam!
We just released a new update that includes a notification center.
With this new feature, Noku users are now able to choose which notifications they receive on the platform and which ones via e-mail.

This is a significant improvement over the previous system, which as you know used the e-mail to deliver tournament prizes.
From now on the Notification Center will become the main way to check what’s going on with your Noku account, regarding our games, your wallet and the marketplace!

Keep an eye at that little bell close to your avatar, that’s where the important news will be delivered!
Of course if you like to receive your rewards and updates via e-mail you don’t need to worry, we made this new feature customizable.
Just head to the link below:
https://noku.page.link/notification-center-settings

From there, you can see a list of all the types of notifications and choose which ones you still want to receive via email. It’s also possible to flag all of them with a X: which would mean that users will stay up-to-date on the platform only, without having to constantly check it for updates.

The new notification center also makes it easier for users to manage their notifications. They can choose to still receive emal notifications for certain types of content, such as wallet or rewards, and turn off notifications for other types of content that they don’t find relevant.

Overall, we consider this new update as a welcome change for our users. With the added flexibility and control over notifications, now you can stay engaged with the platform in a better way and keep an eye on everything!

As always, we will appreciate your feedback on this new update.
See you in-game!
