GalaChain Devs: Non Fungible Tower Defense (NFTD)

GalaChain Devs: Non Fungible Tower Defense (NFTD)

Editor’s Note: We love spotlighting people building on GalaChain. The following article was written by Graham from the NFTD team, the top Judges’ Choice pick during March’s GALAthon. NFTD is a tower defence game being developed by several long-time Gala community members, who are currently working on integrating the game into GalaChain. The game itself offers multiple opportunities to utilize items from across the Gala ecosystem… we love some cross-utilization here at Gala!

Graham (who you may know as cryptograham on Discord) was gracious enough to write not only a description of NFTD and their work at the hackathon for us, but also gave some amazing insight into their process and design philosophy! Far be it from us to get in the middle here… so we’ll hand it off to Graham himself!

NFTD is an arcade style tower defence game with the goal of defending your fortress from endless waves of attacking enemies. You can mine resources in the game by placing resource extractors and use the proceeds of those extractions to buy and place towers to defend your base. There are a variety of towe rs you can place in the game; arrow towers, cannon towers, fire, ice, poison, etc.. all dependent on the NFTs you have in your connected wallets.

The towers in NFTD, are all representations of different NFT projects from various groups/companies throughout the web3 space. The Gala Games project Fortitude is the main source of inspiration, where holding a Fire Tower in your Ethereum or GalaChain wallet lets you place a similar themed fire tower in the game. Having one of the BT Orbs, which dropped about 2 years ago, lets you place an Orb inspired tower in the game with healing range effects on surrounding structures. 

You can find NFTD at!

Our Hackathon Work

During the GalaChain Hackathon at GDC, we introduced A Snoop Dogg inspired  “BeatBox” tower, where holders of the “Death Row Records – Gold Chain” NFT are able to place that tower in-game and holders of the “888 Inner Circle – Blue Realm” NFT can place the “Blue Realm Orb” tower.

Also at the hackathon, we introduced our own custom GalaChain contracts to create $HOPIA, our in-game minable token and “The Tower of Hopia”, a GalaChain NFT Tower purchasable in $HOPIA. $HOPIA is generated through mining activities performed by our in-game extractors. There is a small percentage chance of hitting a HOPIA Motherlode and being able to extract it.  This provides players with another in-game task of protecting their extractors in addition to their fortresses, so they can stay alive longer and get their hands on more of the token.

As part of our custom GalaChain contracts we also introduced functionality for starting and ending games with various pieces of data that we can store for after game analytics.  What’s really interesting about the way we did this is that when you start a game, the custom contract will lock the GalaChain NFTs you are using in-game.

So, when you start to play the game, you can’t immediately send your towers to someone else, that wouldn’t be fair.  Once the game ends, your towers are unlocked, and you can trade as you please.  This is really interesting functionality that I’ve only ever seen available to Galchain. It’s really neat!.

As a bonus, during the hackathon, we had the opportunity to chat with Mark Skaggs, a legend in the RTS space and one of the key minds behind Farmville, Red Alert 2, LOTR: Battle for Middle Earth, and numerous other successful titles. He played our game and was able to give us some excellent feedback on his experience and ways we could improve.

A wild Mark appeared!

This was invaluable information that we wouldn’t have received if we didn’t come in-person to the Hackathon. This moment alone was worth it for me. As an homage to him, we added a secret code in-game to unleash the Kirov Airship from Red Alert 2 in-game. I won’t tell you what the code is, but it’s in there.

The origin of the game

The idea for this sort of cross-chain interoperable game came from a conversation in the Gala Games Platinum Club discord, when forgedincrypto posted a picture of his Fortitude collection of NFTs sayings “Wouldn’t it be cool if I could actually play with these towers in game”, as the Fortitude game is still in development. I then responded, saying that I had built a tower-defence prototype a while ago, while learning some new game development coding concepts, and with a few changes, e.g.. adding in wallet lookups and putting in some specialty towers, we could put out a quick game for people to play while they wait for the real one to launch from the Fortitude developers.

I began working on the project to create the proof of concept, showed it to a few community members, which brought me in-contact with Timboslice (Tim) and Deadily (Drew), who were also excited by true interoperability in web3, so we partnered up, and they began working on a new art design direction.

In terms of how the three of us work on NFTD, Tim leads the design efforts, game art style, tower design, game lore, tokenomics and player economy management. Drew has built out the galachian blockchain integrations, custom contract code and the REST API layer to talk to GalaChain. I (Graham) do all the core game development work needed to play the game, taking the artwork and turning it into playable game objects, wave management systems, upgrades and game progression, scoring and leaderboards. I also do the web3 wallet and player authentication integrations too. There is a lot of stuff involved in making a game and we’re a pretty balanced team seeing it through.  

A lot of existing projects out there build their own NFT collection for their own games. What brought us all into the space was the promise of taking NFTs from one project and being able to use them in different projects, or in different ways entirely, as we own our own assets. 

As a kid growing up, I could take my Luke Skywalker (Star Wars) action figure and put him in my Ninja Turtles Party Wagon with Michelangelo (TMNT) and drive over to go all Cowabunga/Jedi on Shredder (TMNT) and his Cobra villain associates (G.I. Joe). That’s the level of true interoperability that the three of us are looking to build in the web3 space.

For me personally, over the past couple of years, I have been working on a few indie game projects taking NFTs from various projects and mashing them up into quick game prototypes. For example, one of my games, “Vox Battles: The Dead” ( puts characters from the Vox Collectables: The Walking Dead project into a zombie runner style game, where you play as one of the human VOX characters, scavenging for resources, weapons, health boosts, and batteries for your flashlight, you run around avoiding or killing the Walker VOX characters. As you play the game, the eerie music that plays in the background is actually from one of my NFTs from the BT Orbs collection. All of the characters that I used in that game were provided by community members (with attribution in-game).  

I have also been working on a multiplayer battle royale game called Vox Battles, which puts a group of Vox players into an arena, heavily inspired by the Hunger Games series, to battle it out until one person emerges victorious. You can wishlist it on steam now!

VOX Battles is live on Steam!

What I really love about working on NFTD, is that it really expands on the opportunity for interoperability, especially with the thematic design that Tim has created, where each NFT you own becomes a sort of chess piece available to use on your tower defence board, and depending on the board, you won’t be able to use them all at once, so you’ll have to be strategic with which pieces you bring into the match.

Future Plans

With NFTD we are just getting started. The 2D isometric version was our proof of concept, to see if there was appetite out there for a fast paced tower defence game bringing in NFTs from lots of different projects. Turns out, there is.

We’re committed to continue building out the experiences. Adding more NFT project integrations into the current version and working with Gala to bring NFTD to GalaChain, so you can generate $HOPIA and spend it… not just on the few select GalaChain Towers, like the Tower of Hopia, but also on a few other things.

Besides that, we are working on the competitive aspects of the game. The competition we held during the Hackathon saw about 100 players join in on the NFTD fun, but also showed a few platform vulnerabilities that we will need to work out. 

We are moving towards an authoritative server architecture, and I’m taking that opportunity to re-work some core logic and add a third dimension to the game.

In the coming months, as we continue to iterate and fine-tune NFTD with the community, our goal is to truly embody what web3 interoperability and collaboration are all about. If our work with Gala proves successful, GalaChain will play a central role in this mission and we are very excited to be building on chain.

As an editorial, the thoughts and opinions expressed in this article are those of individuals on the NFTD team and not of Gala.

We’re excited to hear more developments for NFTD on GalaChain in the future!

As a foundational pillar of the Gala ecosystem, our Founder’s Node operators have always played a crucial role in shaping the future of our platform. Traditionally, the decision-making process has involved simple proposal style votes, offering a binary choice on the direction of development within the Gala ecosystem.

The Vote

The voting opens at 2pm PT on April 12th and concludes at the same time on April 19th

As you know, we opened GalaChain to external development with the release of the open-source GalaChain SDK earlier this year. The community’s response was nothing short of phenomenal, leading to the creation of invaluable resources by dedicated developers. Among these resources, various GalaChain explorer apps stand out as exemplary projects that not only enhance the ecosystem but also enrich our community.

GalaSwap: April Updates

GalaSwap: April Updates

We’ve been thrilled to see how much the GalaChain community has enjoyed the ability to easily swap tokens on chain using GalaSwap.

As we said when we first released GalaSwap, we originally prioritized getting it in users’ hands as quickly as possible. This means that we’ve got lots of updates we plan to implement, and the next round is here!

Partial Swaps

Starting with this update, you’ll no longer need to fulfill an entire swap to accept it. Likewise, this makes it so it isn’t ‘all or nothing’ for those listing swaps. 

When searching for a swap, you’ll now see a checkbox labeled “Selected Amount”. Using this checkbox, you may accept a percentage of the swap being offered.

You’ll be able to customize the amount of the given swap that you fill, and the rest will remain as an available swap.

You can use this in addition to other full swaps as well to get exactly what you need, without having to try and get an optimal combination of swaps for the exact amount of tokens. you’re looking for.

New API Functionality

We’ve added new API integrations into GalaSwap to allow developers to easily access the GalaSwap API. 

This will open the door to new developments, as builders on GalaChain can now integrate API for GalaSwap functionality authenticated directly through a user’s keys.

GalaSwap itself doesn’t have a monopoly on token exchanges within the GalaChain ecosystem. We built this tool because it was functionality that we thought everyone needed for the good of GalaChain. The end goal is always to make it more useful to those building on and using GalaChain!

Much More Ahead

GalaSwap is still in the early days. There will be a lot more coming – more tokens, more ways to swap and more use for GalaChain devs! 

For now, we hope that these few updates make your swaps a little easier. We’ll be back soon with new features!

Big Start to a Massive Year: GalaChain Q1 Recap

Big Start to a Massive Year: GalaChain Q1 Recap

2024 is an exciting year for GalaChain, and we’ve already hit the ground running! There’s lots coming in the months ahead, but first let’s look back on how much we’ve built so far this year.

Solid Foundation

GalaChain has been live and operational for a while, facilitating live games and transactions within the Gala Ecosystem since October 2022. GalaChain during that time of internal may have seemed quiet to outside observers… but we were in fact very busy streamlining our systems on GalaChain and refining platform and chain processes… all to open the floodgates!

The release of our GalaChain SDK and Creators Portal at the beginning of 2024 was the culmination of this diligent testing and refinement. We spent the time learning the early lessons, and served the community up with tools we knew had the power to implement real solutions to GalaChain.

While many of our experiences with GalaChain were in games, we’ve had the chance to experiment with a wide variety of applications on GalaChain. The infrastructure of the chain isn’t designed exclusively for games… it’s designed to easily live up to the heavy demands of gaming, which is one of the highest bars in the tech world.

GalaChain stood up to the task of live games and highly specialized platforms like Gala Music. The first business of the year for us was taking everything we learned and packaging them up into tools that the next generation of GalaChain builders could use.

Building Up

Just opening the gates to the chain isn’t enough. With the GalaChain SDK in hand, any developer can start crafting a project on GalaChain or plug an existing project into the wonderful web3 world. A robust ecosystem requires more than just the tools to build amazing things though.

The launch of tools like GalaSwap and the community built block explorers provided vital support to anyone innovating for GalaChain. As new projects started to pop up, each provided valuable insights on how to make the chain better for everyone.

This led us to the GalaChain Hackathon during GDC. We’ve done a few hackathons on GalaChain already, but we knew this time needed to be different. With GalaChain open to the world, it was time to think bigger and get more people building on GalaChain.

During the hackathon, we saw lots of really cool things get built on chain. From Team NFTD’s reinterpretation of the classic tower defense genre using GalaChain NFTs to Team NoREST’s creation of a more efficient rest API for GalaChain, GALAthon brought new momentum. New people are building on GalaChain and new applications are pushing the limits of what’s possible through blockchain technology.

Filling Out

We’re confident in the abilities of GalaChain. Its scalability, speed and customization potential are unparalleled, and we think its practical applications speak for themselves. That having been said, the “if you build it, they will come” philosophy is a trickle… and we want a flood.

We’ve been going on the road and telling the world about GalaChain. Aside from worldwide expansions like recently announcing our plans to build a liveops center in Chile, we’ve been getting to conferences all across the world and getting people on GalaChain to start building!

We’ve been announcing partnerships and collaborations with companies planning to be on GalaChain at a rapid pace. We’re establishing new relationships with innovators and expanding the scope of everything we’ve done prior. 

Gala isn’t just changing entertainment anymore. GalaChain can change the world.

The Future Is GalaChain

The first three months of 2024 have raced by, but there’s no checkered flag and champagne. This is just the beginning of GalaChain, and the best is yet to come.

With so many developers and businesses jumping into GalaChain and starting to build, the rest of 2024 will be exciting. We’ve got exciting plans to expand access and utility for GalaChain, but the best innovations in the future are out of our hands. 

Thank you to everyone building on GalaChain. You are the future.

Guardian Papers 2 – Private Keys

Guardian Papers 2 – Private Keys

Imagine losing the keys to your house… in a world with all unbreakable windows where locksmiths do not exist. This is what’s at stake when we talk about private keys, one of the most important tools in the web3 world.

Welcome to the second edition of The Guardian Papers, the series in which we’re taking you through some of the most important security issues in blockchain, one by one. The future of decentralization can create opportunities for bad people as well as good ones; that’s the nature of empowerment.

We’re here to not only empower our community, but also to help equip everyone with the skills and knowledge they need to protect themselves 

What Are Keys?

Keys grant you access to your assets or information on a blockchain. Just like a password, you can use your private key to access your holdings in a wallet address, but the security of a key far exceeds the security of a typical password. Passwords can be hurdles to the villains that stalk the shadows of the digital world, but cracking or brute forcing a private key is a hurdle too high for anyone to jump.

There are typically two types of keys associated with any blockchain address. A private key is your personal proof of ownership and should not be shared with anyone. This private key is known only to you, and due to blockchain’s decentralized nature your private key is how you prove to the network that the assets held at that address are actually yours. This itself prevents many of the methods that the bad guys will employ to prey on individuals in less sophisticated digital spaces.

A public key is the one that your wallet will share while transacting. Your public key is actually derived from your private key through complex mathematical calculations, but due to the high level of encryption, the process can’t be reverse engineered. This means that your public and private keys are matched pairs– one is your visible footprint on the blockchain while one is your personal access code.


Though not every blockchain uses the same names for them, most use some form of private and public keys.

On the Ethereum network, your wallet address actually represents the last 20 bytes of your public key. It is expressed in hexadecimal–  indicated by “0x” at the beginning of the address. Since each byte is represented in two hexadecimal digits, a full address is 42 digits long (0x+20×2)

Your GalaChain address is also expressed in hexidecimal characters. It is comprised of 24 digits, with the prefix “client|”, which can double as a unique user ID for the Gala platform.

On GalaChain, the ability to transact through the Gala platform or dApps built on chain simplifies the day to day use of your keys. Your public and private keys still control access to your on-chain items, however.

There are many independently functioning blockchains and not everything here will always be true for all of them. This is intended to be general information about how keys typically work on a blockchain, but you should always do further research to understand the specifics of any blockchain you use.

How Keys Protect Your Assets

In blockchains that use both a public and private key, asymmetric cryptography is employed to ensure that assets remain protected for a private key holder. This keeps security high even though transaction data and the public key are readily available as public information on chain.

GalaChain operates on asymmetric cryptography, just like many other chains. While your public key is used to sign transactions, your private key always stays exactly that – private.

First, your private key generates a public key with encryption software to complete the pair when you first set up your wallet. Your public key then secures data as it interacts with the blockchain so that it can only be decrypted using the private key that it pairs to. Your wallet safely stores your private key, which now is the only key that can give anyone access to your assets.

There are many nuances and exceptions to the way asymmetric cryptography works on blockchains, and there are even some chains out there that run entirely on symmetric encryption. Understanding how private keys and public keys interact and relate to each other, however, is the first step in keeping control over your crypto treasures.

It’s All In the Name

One of the key components of blockchains is transparency and history. Transaction information and data is readily available and stored within the chain itself, thus making ownership of your assets fully provable. While your public key will be visible on the network and identify your address to the chain, your private key needs to stay just that– Private!

Your private key should never be shared with anyone! This private key is designed to be stored within a wallet and should stay in one. Your private key can be imported to apps and extensions like Metamask, but make sure that you 100% trust the encryption and integrity of anywhere you are sending your private key. 

If someone has that key, they then suddenly own your entire digital hoard. While your private key may be able to be recovered with a seed phrase or recovery phrase, nothing can be done to prevent anyone who gains this key from immediately accessing your wallet. This cannot be restated enough times: Any individual asking for your private key is up to no good!


A wallet doesn’t actually store your currency, but rather stores and controls access to the keys that can access the address the currency is stored at.

This means offline solutions like hardware wallets store your private keys in a secure environment, not accessible remotely.

When your private key is secure in a wallet, it signs transactions without being exposed to the network because your public key recognizes its other half. Though we use alphanumeric characters to express a private key, it’s in fact a seemingly random number of hundreds of digits long– the type of math us mere mortals use to keep your defenses impenetrable. Reverse engineering a private key from a public key is something that is beyond the technology of even a real life supervillain.

Control Your Lock and Your Key

The revolution that blockchain technology represents is all about sovereignty over personal property without barriers in between you and your assets. Maintaining control over your assets opens countless new possibilities, but that comes with responsibility.

Blockchains give you sophisticated tools to protect your assets, but in the end it all comes down to you. Maintaining a thorough security infrastructure on any device that your wallet is connected to will ensure that the lock on your vault is essentially impenetrable… but any lock is easy to penetrate if you hand over the key.

Your private keys are yours and yours alone. They should never be shared with others or transmitted digitally, and should preferably be stored offline whenever possible. Your keys are direct access to your treasures, so that’s what the enemies of digital sovereignty will come after… but you’re not alone in this fight. 

As long as there are easy victories to be had in our community for the bad guys, they’ll be hungry for more. Only by educating and empowering everyone within the blockchain world to protect their private keys can we shut out the brigands who seek to cheat their way through this digital frontier.

The First and Last Guard

We’ve already covered a lot of ground in The Guardian Papers on how to keep yourself secure in the decentralized world, and our next installment will take us even further yet as we explore how 2-Factor Authentication is crucial for healthy defenses.

In the world of Web3, you are the first and last guardian of your assets. This may sound overwhelming, but that is the cost of the power of controlling and owning assets without the interference of a larger organization. You have the tools at your fingertips to easily maintain defenses that can’t be matched in the pre-Web3 world. 

Here at Gala, we believe that empowering the players is about more than just ownership. It represents a responsibility to educate and arm the community with the knowledge they need to protect their control over their assets. As a community, the responsibility to spread wisdom that could help any member protect themselves is carried by all of us… until none of us are threatened. 

Our security on chain may be strong, but we are always infinitely stronger together.
