Tranquility City - Metaverse on Harmony

1. Tranquility City

2. Type of funding

Product launch/investment

3. Proposal overview

We are a team of passionate developers that would like to build a metaverse on the Harmony blockchain. The project is called Tranquility City. We took inspiration from a lot of other succesful and cool projects that we found around the blockchains (such as: Aurory, Habbo, XYA etc.)

Our goal is to have an instanced type game where players can own their private housing and meet up with friends in common areas such as a community center and enjoy various activites together such as casinos. You would be also able to invite your friends over to your private housing. Also, the housing would be completely customizable by buying items on the in-game market.

The complete game consists of the following components:

  1. Private housing (NFTs) - 2500 + 1 total
  2. Playable characters (NFTs) - 10000 character NFTs (with special statuses)
  3. LUMEN token - the main currency for in-game purchases

Our aim is to provide a space for Harmonauts to play together with their friends and have fun.

We are currently developing the CLOSED BETA that will allow whitelisted community members to try out the game and provide us with feedback. After the CLOSED BETA is done, we will do an OPEN BETA for everyone to take part in (up to the limit that we will decide later). Once the feedback is implemented, we will start the minting for all components of the game and we will launch the token and then everyone will be able to play the game. We haven’t decided yet if we would allow more than 10000 people at one time since there are only 10000 NFTs. If the community wants it, we will allow discounted minting of character NFTs with lesser statuses.

We are currently in the inception phase and we don’t have a lot of users:

Discord - 32 members
Telegram - 45 members

We have a working prototype that you can currently see in the trailer (we will post links below).
You can currently log in your MM account, you will be prompted to select your character, and then you will be sent to the community hub. In the community hub you can see the other players that have also connected and you can also chat with them. Right now the community hub is just a small pub on the beach but we will be expanding upon it when necessary. We plan to model the entire beach, the surrounding areas and all the other parts of the city.

All the houses, apartments and pieces of furniture/decorations have been created from 0 using Blender.

The game itself is being developed in Unity.

We are looking into ways to prove ourselves to the community without doxing ourselves dirrectly. A way we thought would strike the right balance would be to dox ourselves through someone. Crypto Gainz (a community validator) has approached us and asked us for some help with his personal projects and we proposed to him that he could dox for us to the Harmony team instead of paying us for our help. If the community thinks this is a good way to add legitimacy to our project, we will pursue this avenue.

4. Team
There are currently 2 of us developing this game. Myself (0xsparkles) - as Solidity dev and general back end development and Beaver as 3D modeller and game developer.

We are both developers and we are passionate about blockchains. We have been working on multiple projects throughout our lives and we have accumulated the required experience to bring this vision we have to reality.

You can contact us on Telegram and Discord

5. Proposal ask

We would need somewhere between 50K-100K USD.

We would be using the money to hire more devs/artists and pay for development costs (server fees, assets, etc.). For instance, we would like to have a sound designer because this area is something we are personally lacking in.

6. Justification

We are a small team of developers that are working on the project part time, in the afterhours from our full time jobs. We would like to improve the quality of the visuals and functions of the game, but that, for us alone, would take a long time. We would like to expand our team and to bring in some professional help when it comes to areas such as music which we do not have experience working on. We would also like to launch a product with as little errors / bugs as possible, for that, it would be great if a professional could help review our code/audit us. This as well costs money. It is not possible to develop a metaverse by yourself, hence our application for the fund.

One thing to note is that we both have full time jobs for now and we are developing this entirely in our free time which is also something to keep in mind for our justification for this funding proposal.

7. Metrics for success

Our personal milestones are:

  1. 500 users across platforms before the CLOSED BETA
  2. 1000-1500 users across platforms before the OPEN BETA
  3. As much as possible for the launch of the game
  4. A DAO for the community of our game

Im all for a metaverse on Harmony! Id love to see this gain traction…


@0xsparkles great looking start with the web assets. The POC fits the Launch category. Will you guys be able to abide by the Launch guidelines in Apply for Grants or DAO?

Applications of each launch must have prototyped a feature-full product. Harmony helps incubate these founding teams with product development, fundraising, and talent recruit. We recommend a $50K equity-free contribution each: $10K after launching a feature-complete product on our testnet, $10K after mainnet launch, $10K after forming a DAO with its community, and $20K for after 10K users


@0xsparkles I’m looking at $50K to kickstart Tranquility City. Any thoughts on the prior comment?

Hello Jack, sorry for the late reply, we have been busy getting ready for our upcoming Testnet mint test with the community.

We would very much like to proceed with this the application as you stated it.

Also, if you would like to join us for our test minting, could you please get in contact with Crypto Gainz (@stocksonlygoup on Telegram) to be added to the whitelist?

Congratulations @0xsparkles! Approved for a $50K Launch grant :clap:

We look forward to a feature completion on Testnet to include a user interface, connection to a wallet (Metamask, Harmony ONE Chrome Extension, etc.), and can be tested end-to-end by at least 100 users

Please post your MultiSig wallet on a reply here, thank you.

Hi Jack! This is amazing news! Thank you so much for getting back to us. This will definitely help us with further development. Feel free to contact me, Beaver or Crypto Gainz. :grinning_face_with_smiling_eyes:

Looking forward to hearing from you!

Hi everyone! I am Crypto Gainz, community validator and a new addition to the Tranquility City team.

I wanted to give you a quick update on our progress and what we have been doing :smiley:

The testnet event went very well, people enjoyed it and we had a minimal amount of bugs which is nice. You can see the full event here, on our YouTube channel: Tranquility City - Testnet Event & Q&A - YouTube

The testnet will remain open as the Harmony team has requested from us, we will regularly push updates there/take it down for maintenance or to deploy new contracts and stuff like that

The mainnet minting will be open very soon and we will allow people to mint their real estate

We also have a new developer on the team that will help us with the database for the game (for achievements, quests, levels, professions, etc.)

The LUMEN token IDO will also happen soon in collaboration with Artemis Protocol. We want a fair launch so a controlled environment like an IDO is the best way to go.

We are currently working on the following things (our short term goals):

  • Getting more devs on board
  • Fixing the networking issues (we need to port to a new networking package because the previous one is deprecated for WebGL)
  • Making the chat system look nicer and more integrated in the UI
  • Working on community engagement and getting a headstart on DAO progression
  • Currently looking into a nice way to update the community with AMAs and videos in the form of dev journals (short 10 minute videos where we present our progress together with the team)

We will keep you all updated!

Hey everybody! I’m Hoofdcoach, a community Moderator over at Tranquility City.

I want to give you an update of our latest progress:

To continue with what CryptoGainz announced, we’ve extended the dev team with the addition of Cringe and Beancurd. They’ll be working on implementing the off-chain backend on a part-time basis.

We had a successful shilling competition amongst the community. With @Herobuddy.One taking the grant prize of 1 Medium apartment + LUMEN Airdrop and the well earned ‘Master Shiller’ role on Discord.

Also, we’re moving our main game developer Beaver into a full-time dev role very soon. Due to the funds we’ve collected from in-game real estate NFT minting we’re now able to cover costs and free up resources. About that minting: We started minting on mainnet last week. Within 20 minutes our 50 houses were sold out, followed by the 100 premium apartments in less than 12 hours.

We still have plenty of real estate for everyone to buy over at The prices are as follows:

  • Small apartment - 400 ONEs
  • Medium apartment - 900 ONEs
  • Large apartment - 1800 ONEs
  • Premium apartment - 3500 ONEs
  • House - 5000 ONEs

Housing looks like:

Because we love to colab with other projects, we were invited to an AMA over at MagnetDAO last sunday. The Magnet community is deployed on Avalanche and took an interest in our metaverse project as a investment prospect. We loved the questions we got during the AMA and want to thank the MagnetDAO for extending the invitation.

Now that we’ve looked at what has passed, let’s take a look at what’s ahead! Exciting times for inhabitants and enthusiasts of Tranquility City are coming!

Furthermore we’d like to clear up some confusion on the requirements needed to play this game:
You’ll need either a real estate NFT, which can be minted right now, or a character NFT to play the game. If you only own real-estate you’ll play as a default character.
The character NFT’s will be minted in $ONE as well and we’re making 10.000 of these available. Details on when the character NFT’s will be minted and the price will be communicated through our socials, down below!

Lastly, the team wants to recognize and thank you all for joining us during the last couple of weeks. The community has been steadily growing as we continue to push content and it’s been an absolute blast to answer all your questions and see the great suggestions we get from you! Please join us on one of our socials and become a citizen of THE metaverse on Harmony $ONE <3

And since new users can only put 1 embedded image, a double post with a sneak peek :smiley:

Our game development has been steady, for instance last week Beaver worked on creating assets for the metaverse as you can see a sneak peek of below:


This is really cool project and congrats on your successful funding application. I am wondering if you were interested in potential collaboration. I am planning to submit proposal as well. We would be looking to create audio-visual sculpture that would be used across different metaverses. I think it might be cool collaboration. If you are still looking for sound designer I might be able to help as well.

Just poppin in here to say that it’s refreshing to see the development videos being shared with your community as often as they are. Transparency goes a long way. Keep up the good work!


Hello fowks! I’m Hoofdcoach, a community moderator over at Tranquility City, and I’m here to provide you with an update of our progress.

It’s been 4 weeks since my last update and boy has the Dev team been busy. We’ve completed the short-term goals said out by Gainz in one of his previous posts over here and added even more functionality on Testnet. Our Casino is starting to take form and Beaver implemented a true day/night cycle tied to the current time in UTC.

We’ve had a succesful launch on testnet with over 100 unique users trying out initial state of the game. The test gave us a good overview of bugs that were in the game and we’ve implemented a lot of feedback we’ve received over on our Discord and Telegram. Thank you for making these testevents so exciting. We’ve recorded both testnet events and made them available on our YouTube.

Right now we’re prepping for our native token, called LUMEN, to launch on the Artemis Launchpad on the 17th. We’ve summarized the info in this neat little infographic:

LUMEN will be used for the in-game marketplace that is being build as we speak. You can use LUMEN for instance to buy decorations for your house/apartment, dress up your Character NFT (minting TBA) and bet with it over at our Casino. We’ve also talked about staking over on our socials and more details about this will soon follow on our channels along with more info about the tokenomics of LUMEN.

To celebrate the upcomming launch, you’ll find that we are running several promotions to give back to the community what they’ve given us, a lot of joy. Hop on over to our Discord or Telegram to find out more. Some cool apartments are up for grabs!

After the IDO has completed we’ll be looking into deploying the game on Mainnet and with it expanding the utility of LUMEN. Many of you have already tested out the game and have seen the progress we’ve made, but for those newcomers, there is still plenty of oppertunity to get involved into the game and/or testing it. Hop on over to our mint page , mint your apartment and you’ll be granted access to our testnet build, untill we’ve deployed on mainnet. Any feedback is welcome, so don’t hesitate to tell us what you think. After all, the inhabitants of Tranquility City will have a say in how this game will evolve to be THE metaverse on the Harmony blockchain.

Hope to see y’all soon in our Discord/Telegram!

Hello @tranquilians

We’re pleased to announce that we are partnering with Hermes Defi!

About Hermes:

Hermes Defi is a decentralised hybrid yield optimizer(yield farm and yield aggregator) project that started in July last year on Polygon Mainnet.

Their hybrid approach allows investors to both stake assets and earn rewards in $PLTS, as well as locking $PLTS in the bank/treasury, to be paid out in DAI.

Hermes Defi Milestones:

  • Live on Polygon mainnet in August 2021 with $IRIS
  • Live on Harmony mainnet in December 2021 with $PLTS
  • Created their own RPC and validator for the Harmony network in January 2022

The partnership:

Together with Hermes we’ve created a single-stake $LUMEN pool over at Hermes Defi. You’ll be rewarded in $PLTS. To celebrate this moment we will have an AMA in our Discord with the Hermes team where you can ask both teams about our partnership & projects. When? This Thursday at 01:00 (GMT+1).
During the AMA we will announce the start of this pool. See you then & there!

@giv Could you please confirm that the KYC has been done for me? In other words, can you confirm I am fully doxed to the Harmony team? Thank you very much!

@Crypto_Gainz @Hoofdcoach Hi, I’m with Harmony core team working on Metaverse. Would love to talk about where you’re at, and to see if there’s anything I can do to help, including seeing how assets created in Tranquility City can be interoperable with other metaverse projects. Please PM me and would love to talk.

I left the team of Tranquility City a couple of weeks ago because of personal issues. It was really fun working with the team and building out the project but my personal life got in the way. If the team wants to access the grant from Harmony since they didn’t receive anything, they need to restart the procedure.
