The essence of the game

The 22nd century saw the beginning of the period of Great Cosmic Discoveries. Interstellar travel, which was previously an unattainable dream, became a reality and was now accessible to anyone. Humankind’s cosmic expansion was declared the supreme challenge. In order to speed up this process, the United Earth Government decided to sell some planets that were already settled to private parties. It also passed a law that guaranteed discoverers the right of ownership to the planets they found.

These events created the conditions for the emergence of a new caste of entrepreneurs whose goal was to conquer the Galaxy. You are one of them. After you acquire your first planets, you’ll receive all the resources you need to increase your wealth, build up a fleet, and become a tycoon on a galactic scale.

Not only will you reap purely economic rewards, you can also explore the world of 0xUniverse. The artifacts you find on the planets will tell you the story of other races that populated the Galaxy before human beings came along. By joining forces with other explorers you’ll even be able to figure out the secret of how life began!


To join 0xUniverse, you’ll need one of the following browsers: Chrome, or Firefox.

Also, like any entrepreneur, you’ll need a wallet that holds a little seed capital. For this game, MetaMask works perfectly as a wallet if you play on desktop. Or you can use Arkane wallet if you play on your mobile device.

To set up MetaMask, simply install the browser extension and then create your wallet. Be careful: MetaMask is independent of the 0xUniverse application. You are the only one who has access to the funds it holds. Make sure to keep the password to your wallet in a safe place. If you lose it, no one will be able to help you access your wallet.

To set up Arkane Wallet, we invite you to watch this guide: how to set up a wallet with Arkane.

Once you’ve set up the compatible browser and created your wallet, you’ll be able to sign up, meaning that you’ll be able to take part in the cosmic expansion of the world of 0xUniverse. Launch the game and click on the PROFILE window. Enter your email address and the name you plan to make famous. Then all you need to do is read and electronically sign the Privacy Policy and the Terms of Use by clicking SIGN in the opened MetaMask window.

Buying a planet

The first thing you need to do after signing up is to acquire a planet (learn more about planets and how they’re different from one another). There are two ways you can buy planets. Below you will find out how to do it via the Auction. If you are new to crypto and the game, you may want to use the Hypermarket and pay with USD. Read the Hypermarket paragraph to learn more about it.

Back to the Auction way now. Open AUCTION, select the FOR SALE tab, and choose a planet. In the window that opens, you’ll see a description of the planet, and in the bottom right-hand corner you’ll see the BUY button.

Click on it. That will open the MetaMask window (or Arkane wallet window), which will ask you to confirm that you are using Ether to buy the planet. Click SUBMIT (if you use Arkane you may need to enter a special Pin to sign in first) to confirm that you agree (if you don’t have enough Ether, you’ll need to top up your wallet). That’s it. In a few minutes your request will be processed (learn more about blockchain transactions), and you will own the planet!


Hypermarket allows players to get planet bundles for USD via PayPal/CardPay in the web version and Apple Pay/Google Pay on mobile devices. Please note that the Hypermarket won’t be competing against the current game Auction as the prices there are higher. It has been implemented to allow new players, who aren’t familiar with blockchain and don’t have crypto, to start playing the game. Also, it is noteworthy that there is a 10,000 limit for the FIAT planets. Afterward, Earth will be buying planets from the Auction to sell them to the new fiat players.

Inventing a spaceship

Once you’ve taken possession of a planet, you can start building spaceships, but first, you need to invent them. In order to discover a new type of spaceship, open the MY SPACESHIPS window. There you’ll see the progress of the accumulation of knowledge – you need this knowledge to invent new types of spaceships. Knowledge is created by the people who inhabit your planets (1 person provides 1 piece of knowledge per hour). That means that the more planets you have and the more densely they’re populated, the more often you’ll be able to invent spaceships. And the more inventions you’ve already made, the more likely it is that you will receive a more powerful spaceship (learn more about spaceships and how they’re different from one another).

When you’ve accumulated the necessary amount of knowledge, the INVENT A SPACESHIP button will appear. Click on it. That’s it – you’ll soon invent a new spaceship (this process is not a blockchain transaction).

Discovering new planets

Now that you’ve invented a spaceship, you can build it and send it out to look for new planets. To build the spaceship, you’ll need resources and a population, the future colonists. You might get lucky and the types of resources you need can already be extracted on your planets, but if that’s not the case, you can buy planets with the missing resources in the Auction.

Resources can be transported quickly between planets, so if you have 30 units of iron extracted on one planet and 50 on another, and you need 70 to build a spaceship, you don’t need to worry – the iron will be collected and automatically delivered to the planet where you need it. Things work a bit differently for colonists: they all need to be on the planet from which the spaceship will be launched.

You can track the collection of resources and colonists from the MY SPACESHIPS screen. When the process is complete, the BUILD AND LAUNCH button will appear. Click on it. The command interface will show a star map, on which you will need to choose the launch planet. That’s where the colonists will be gathered and where the spaceship will be launched. Confirm your selection in the MetaMask window that opens. In a few minutes the expedition will be completed (learn more about blockchain transactions), and you’ll find out the results.

If the expedition is successful, you’ll find a new planet. If not, you’ll lose the spaceship. The success of the operation depends on the characteristics of the spaceship and the sector where the launch planet is located. The less explored the selected sector of the Galaxy is, the better your chances are of discovering a new planet.

Once your spaceship finds a planet, it will land on it and you’ll become the planet’s owner. Colonists from the parts of the ship will put together the first base and start extracting resources. Space travel and building colonies are complicated, dangerous undertakings, and only 60-90% of those who dare to do it survive.

Keep in mind that the next time you want to build the same type of spaceship, you’ll need one and a half times more resources. So it’s more efficient to invent new types of spaceships than to keep building the same one.


The most valuable thing in 0xUniverse is the planets. The more there are, the more opportunities you have.

Every planet has its own unique appearance and features: number, date of discovery, name, owner, rarity (common, rare, epic, or legendary), sector (learn more about the map of the Galaxy).

On every planet, a population grows and resources are extracted. Each planet is rich in its own way, so the speed of growth and composition of the resources are different for every planet. Like the planets, the resources are classified as common, rare, epic, and legendary. You’ll need them to invent and build spaceships.

Keep in mind there is a resource storage cap allowing players to have a certain resource amount at a single time. Multiply your resource production rate by 200 to see how big your cap is. Note that this only concerns storage and the total amount of resources is unlimited.

Also, the legendary planets have their own stories, which only the owner can see (learn more about the story of the world of 0xUniverse).

Planet leasing and renaming

The way planet leasing works is: a planet’s owner sets the price that he’s willing to sell his planet’s colonists for. For instance, the owner sets 0.02 ETH as the price for 100 colonists. After that, other space explorers will be able to launch spaceships from this planet by paying to the owner for the colonists provided. Say, you need a 250 strong crew for your ship. That means you should pay 0.05 ETH (250 / 100 * 0.02) for the owner’s colonists. The owner then gets the entire amount minus a 5% tax imposed by the United Earth Government. That would be 0.0475 ETH (0.05 * 95%). Payment for your rented planets can be found on the transactions list. Once the rent is done, the planet population is decreased according to the renter’s request. If you want to cancel the rent, set the rent price to 0.

Planet naming allows you to name your planets after paying the United Earth Government 0.01 ETH for the operation. There are but a few restrictions:

  • The name should be shorter than 12 characters
  • You can’t change legendary planets’ names
  • You can’t use offensive language and create duplicate names of legendary planets

The United Earth Government is carefully keeping an eye out for any violation of these rules, and should any such violation occur, the Government will conceal inappropriate names from other explorers (the name will still remain on the blockchain). If you’ve found a planet name that offends you and the Government has overlooked it, let us know at

The Galaxy

The map of the Galaxy is divided into 1,000 sectors (25 x 40). Each sector contains a group of planets that are close to each other. In the interest of simplicity, the command interface doesn’t display the exact coordinates of a planet; it only displays the sector. For example, Earth is located in sector 12,0.

Each sector has an average of 1,000 planets that are suitable for colonization. The maximum number of planets in the 0xUniverse galaxy is 1,000,000.

The planet Auction

The current laws of cosmic expansion guarantee freedom of trade in new planets. Anyone can freely buy and sell planets on the Auction. To put a planet up for sale, click SELL on the screen of the planet you’d like to sell. Then set the duration of the auction and the starting and ending prices. During the auction, the price will steadily fall from the starting price to the ending price. For example, suppose there’s a planet being sold on a three-day auction with a starting price of Ξ8 and an ending price of Ξ2. This means that at the beginning of the auction it will cost Ξ8, one day later it will cost Ξ6, two days later it will cost Ξ4, and by the end of the third day the price will drop to Ξ2. After you enter all the parameters, the MetaMask window will appear. Confirm your decision. That’s it. In a few minutes the planet will be available for sale on the auction (learn more about blockchain transactions).

During the auction, the resources on the planet cannot be used. That means that if you need the resources, you must cancel the auction. To do so, click CANCEL on the planet’s screen. Then confirm your decision in the MetaMask window. In a few minutes the planet will be removed from the auction and you may use its resources.

Keep in mind that the planets, after their Auction time has expired, will automatically stay on sale until someone buys them or you bring it back manually by canceling the auction (Alt+C combination).

The United Earth Government

The United Earth Government is the organization that serves the interests of all of humanity. At this time, when the domestic problems of the native planet have been resolved, the servant of the people turns all its attention to the new worlds.

In particular, this body maintains order and keeps things operational Auction. In exchange for performing this work, the Government collects a tax: 5% from each purchase.

In addition, the United Earth Government keeps track of the balance of the market. If demand far surpasses supply, the Government expends Earth resources to open new planets and add them to the Auction. The Government’s options are limited by Earth’s resources; that means that this right will not be abused.

Furthermore, the Government reserves the right to give discoverers up to 10,000 planets in appreciation for helping to popularize expansion among Earth’s population.

Spaceships have the following characteristics:

  1. Rank – this represents the level of the spaceship’s technical sophistication (a rank 2 spaceship is better than a rank 1 spaceship, but building it requires more resources)
  2. Power of the engines – these expand the search area – in other words, the chances of finding a planet
  3. Power of the radar – this increases the chances of finding a rarer planet
  4. Size of the accommodation module – this determines the number of colonists who are transported
  5. Resources needed for construction

Top up the wallet

You can buy the amount of ether you need and transfer it to your MetaMask wallet on one of many cryptocurrency trading platforms, such as Changelly, Coinbase, Indacoin, etc. The process usually goes like this: you indicate the amount of ether you need, the platform calculates the amount of dollars/euros you need for the exchange, you enter your credit card details and confirm the exchange. If you are using the platform for the first time, the service will ask you to show your passport to confirm your identity. This is a normal practice – banks do the same thing – so you have nothing to worry about.

Story of the world

The story of the world of 0xUniverse is uncovered in the descriptions of the legendary planets. With each new story, you’ll be able to form an increasingly complete picture of what happened in the Galaxy before humanity began its expansion beyond its native planet. Moreover, the most dogged explorers will be able to figure out the mystery of the origin of life and discover the way to the secret, most valuable planet.

However, the description of the planet is visible only to its owner. In order to learn more, you’ll need to own legendary planets. But that’s not the only solution. You can contact the owner and, using your diplomatic talents or trade, agree to exchange information. Also, keep in mind the United Earth Government will be publishing news on legendary planets via its space media 0xTimes. And don’t forget to check out the discord storyline channel where some descriptions are shared voluntarily by the community.

0xUniverse is different from many other games. It operates on the decentralized network known as Ethereum. Most of the game’s operations exist independently and operate on thousands of computers around the world, while the data are held securely in the blockchain.

Such an architecture guarantees secure ownership of the planets. In addition, this enables the open market to operate – that is, the planets’ owners can trade planets directly with one another. Using their brainpower, players will be able to earn considerably more ether than their initial investment. Keep in mind that ether is not an internal game currency needed only by 0xUniverse players, but a commonly used currency that can be exchanged for dollars or euros.

However, there is a downside to such an approach. The decentralized processing of requests is more time consuming than the traditional approach. It takes several minutes to record information (e.g., a purchase of a planet) in the blockchain. Also, these operations cost money, which is needed to compensate for the work of those thousands of computers – this is known as Transaction Fee.

When you launch any operation that alters the blockchain, you’ll see the MetaMask window, which will ask you to approve the transaction. It looks complicated, but generally, you don’t need to worry about the details; you just need to click Confirm. But if you’re interested, let’s look at it a little more closely:

  1. At the top, “Contract deployment” usually shows you the address you are sending a transaction to.
  2. The amount you see below will normally let you know how much you should pay (the sum of the transfer). If you are buying a planet, this is where you’ll see the cost – that is, the amount the seller will receive. Otherwise, the sum is equal to zero
  3. Gas Fee – Ethereum charges a fee for every computational step that the network takes. Fees cover any he operations you carry out.
  4. Gas Price – you will see this adjustable value field when you’ll actually be making a transaction Gas price directly affects the cost to complete the transaction. The higher the Gas Price, the faster your transaction will be processed, but the more gas fees you’ll need to pay. On days when the Ethereum network is overloaded, the Gas Price will need to be set higher (you can look at the recommended value at
  5. Gas Limit – this field is also visible when you start an actual transaction. It is calculated automatically; you can ignore it
  6. Total – the total amount of ether that will be spent to execute this transaction, i.e., Amount + Gas Fee

After you confirm the transaction, it will be processed and the result will be saved in the blockchain. This usually takes 3-5 minutes. You can check the status in the TRANSACTIONS window. We also recommend that you sign up for notifications in the SETTINGS window. That way you’ll receive alerts even if the browser tab with the game is closed.


The United Earth Government decided that by joining forces, space explorers could achieve even more significant results in conquering the Galaxy, build more complex and flexible economy, create a more sophisticated management model, and even make a breakthrough in further discoveries. For explorers who have the capabilities and desire to engage themselves even more deeply into the laws of 0xUniverse, the United Earth Government created 3 corporations – Forge, Eternity, Dominion and sold 100% of the shares to entrepreneurs. The new owners immediately began to develop their corporations and attract new members, selling smaller shares on the market. In the future, the Earth Government is planning to create new corporations, but there will definitely not be many of them so that the efforts of discoverers unite and not dissolve in numerous groups.

Corporation share management

Each corporation has 10000 shares (100% in total, where 1 share is 0.01%). Share can be gifted to other discoverer or put up for sale. When put up for sale, you need to specify the number of shares in percent, the price of 1 share and the amount of cash out, which determines what percentage of the sale amount (minus 5% tax imposed by the United Earth Government) the owner will receive in his personal account, and which part will be transferred to the corporation.

Corporation management

The leader of the corporation is a brave discoverer and a manager appointed to be the head. This role can be played by any space explorer who has collected at least 50.01% of the votes according to the results of internal corporate voting. Corporation’s success and earnings of all participants largely depend on the actions of the head. The head of the corporation can:

  1. manage the corporation’s planets (buy, sell, gift, rename and rent);
  2. change the name of the corporation and its logo (to change the logo, the head must apply to the United Earth Government);
  3. initiate the payment of dividends to the members of the corporation (the head decides when and how much to distribute from the balance of the corporation between the shareholders in proportion to their shares).


Having acquired a share of the corporation, you become a full member of the corporation and have the right to vote. The owner of 5% or more shares may nominate a new candidate up for a vote (create a new vote). A candidate can be any discoverer (for example you can vote for yourself). The participants owning less than 5% of shares cannot create a vote but can participate in already created open votings.

The voting ends with the appointment of a new head of the сorporation as soon as the candidate has gained more than half of the votes (50.01%). The maximum voting duration is 14 days. If during that time the candidate has not received the required number of votes, the voting is closed and the current head retains his position.

In order to avoid cheating votes, voting participants are prohibited from transferring/selling their shares until the end of this voting. For the same reason, the share offered for sale will be withdrawn from sale if the owner decides to vote with it. After the completion of the voting, the restriction on the transfer of shares is removed.

Corporation development

Through the efforts of all participants and, above all, the head, the corporation will increase its income and influence in the Galaxy. Development can proceed in the following directions:

  1. Trade. Efficient trade in the planets will make a corporation profit.
  2. War. While military operations in 0xUniverse are prohibited, the situation is heating up and it is likely that this will change soon. Corporations will be able to control the sectors of the Galaxy and receive income from them.
  3. Production and logistics. Corporations will be able to make money exploring 0xUniverse outside of the known Galaxy. So far science has not advanced so far, but the examination of the history of the Hidden Planet has already begun to produce results, and it seems that there will soon be a breakthrough.

Buildings and Energy

Constructing buildings on the planets you own is yet another feature of 0xUniverse that can really help you in your space colonization efforts.

You can expect various types: factories, decorative buildings and transport stations (these 2 will be introduced later). You can construct 1 factory, 1 transport building and 3 decorative buildings on a single planet. To build any of them, you will need energy tokens which can be gained from several sources. By the way, corporations will be solid energy consumers after the Wars update comes out.

What do I need to know about these energy tokens?

Energy will be required to not only construct buildings but also battle fleets (a feature to be added in the future). It is also used to boost your ships’ characteristics: one boost will cost 1 energy and is active on your next ship launch making its radar and engine 20% more efficient as well as requiring more population. After the launch the ship’s parameters go back to their old values.

Energy tokens can be in two states. Tokenized aka 0xE (which is an ERC-20 token) and Detokenized aka Energy (stored on the game server). Its initial state within the game server is Detokenized. The next game update will have a special contract added that will allow players to turn – via a blockchain transaction – Detokenized energy into Tokenized energy, thus making it possible for anyone to trade it with other players.

If you check your profile you will see it displaying a certain amount of energy you own in these 2 states mentioned above. If you have 100 energy then you may see, say, 70 DE (detokenized) and 30 TE (tokenized).

Where does energy come from?

Firstly, factories – one of the buildings types – will produce it. They will create energy in detokenized form after extracting it from the planetary core.

Secondly, you will be able to get energy tokens from other players. That is its most important source after the energy market is introduced to 0xUniverse.

Thirdly, limited energy sale by the UEG: Earth will be selling a very limited batch of energy tokens upon update release to those interested.

Fourthly, there is a surprise feature yet to be added in the future that will let you get some energy, should you decide to use it.

The November 2019 intergalactic contest was “patient zero” when all its participants got a few energy tokens as a reward for joining the event.

Could you tell me a bit more about factories?

First of all, factories can only be built on a rare, epic, and legendary planets (common planets won’t let you build factories on them but their resources will still be required!).

Factories need two kinds of resources to operate. Your planets’ resources and time. So you will be getting energy tokens from, for example, a certain amount of a planet’s resource + your time spent to produce it. Planet rarity also plays a role in determining the amount of extractable energy.

Moreover, factories will have 3 levels (1 to 3). The resource rarity type and their amount required for a factory to produce energy will change upon each level upgrade. Level 1 factory requires 1 Common and 1 Rare resource. Level 2 factory requires 1 Common, 1 Rare, and 1 Epic resource. Level 3 factory requires 1 Rare, 1 Epic, and 1 Legendary resource.

Factories have energy capacity and production velocity. The capacity value becomes known when the factory is built. You will see (in the factory screen) how much energy you can collect: for instance “0/2”. Here 2 means the max energy amount that can be produced by a level 1 factory (from last production date to current production date). It increases with each factory level. Velocity means how fast energy is produced and depends on the factory level, for instance, 0.25 is the velocity rate for a level 1 factory.

Keep in mind: there is a limit to how much energy can be extracted from a single planet before its core is exhausted. The amount of extractable energy is determined when a factory is built. Depending on the factory level, you can produce 20%, 50%, or 80% of all available-for-extraction energy. How do I squeeze a planet dry and get to 100%? Well, that is what the surprise feature mentioned above will be for.

Expansion Beyond the Known Galaxy

Scientists of the United Earth Government have found that black holes can be used for intergalactic travels. To do this, a space station, the Gate, needs to be built near a black hole, it will stabilize the singularity and use the curvature of space-time to move spaceships over great distances.

As a result of experiments and numerous launches, the scientists discovered a new galaxy and called it Edge. Discoverers will be able to send ships between the Home and Edge galaxies, for this, Gates must be built near the black holes connecting these galaxies. Not any spaceship is capable of withstanding such a journey, but the only rank of 5+ (or 4+, if the Gate is improved). When launching a spaceship through a black hole, the Gate’s colonists are used, as well as the discoverer’s resources collected in the galaxy from which the ship is sent. Moreover, if the discoverer is not the owner of the black hole, he should pay rent fee to the owner for using it and its colonists in the currency of the galaxy to which the spaceship is sent (for example MATIC if your target is the Edge galaxy).

Matic Blockchain

In general, Matic and Ethereum blockchains are very similar. They use the same address format and cryptography standards, which means that you don’t need to create a new account, an existing pair of public and private keys from Ethereum will suit.

Matic also supports the same wallets. 0xWallet and Arkane will work out of the box. To configure MetaMask, you need to add an additional network with the following settings.

Network Name Matic Mainnet
ChainID 137
Symbol MATIC
Block Explorer URL

MetaMask Matic

However, there are also some differences. The main advantage of Matic is that it works much faster than Ethereum, which means the commission for transactions in it is dramatically lower.

Matic blockchain uses MATIC tokens as the main network currency similar to ETH in Ethereum. To purchase it, you need to buy MATIC tokens on the Ethereum network first. To do this you can use any exchange (for example, at Uniswap or Binance) and then transfer them to your account. After that, you need to convert the tokens from Ethereum to the currency of the Matic mainnet using the Matic Wallet application (open the Matic Wallet tab and click on the Deposit button). The wallet will suggest you submit several transactions – you need to confirm them, then wait for a few more minutes until your account will be topped up with Matic currency.
