Success Stories: Real-World Impact
We've helped game studios and metaverse platforms build thriving digital economies. Here's how.
Case Study: Launching a Player-Owned Economy for "Aetheria" RPG
Industry: Gaming (MMORPG)
Client Overview: A mid-sized indie game studio with a passionate community around their fantasy MMORPG, "Aetheria." They wanted to reward their loyal player base and create new revenue streams by converting their rare in-game items into true digital assets (NFTs) that players could own and trade.
Client Testimonial: "Errna didn't just build us a marketplace; they helped us fundamentally transform our relationship with our players. The transition to a player-owned economy has been a game-changer for engagement and revenue. Their expertise was indispensable." - Alex Chen, CEO, Aetheria Games
Problem
The studio's revenue was solely dependent on new game sales and cosmetic microtransactions. Players who spent thousands of hours earning rare items had no way to realize the value of their efforts outside the game's closed ecosystem. The studio feared losing players to newer Web3-native games.
Key Challenges
- Integrating blockchain without disrupting the existing game balance.
- Making the technology accessible to non-crypto-native players.
- Ensuring the marketplace was secure and could handle high transaction volumes.
- Designing a system to mint existing in-game items into NFTs fairly.
Our Solution
We developed a phased, end-to-end solution built on the Polygon network for low gas fees:
- NFT Minting Bridge: Created a secure, one-way bridge for players to convert their legendary in-game items into ERC-721 NFTs.
- Branded NFT Marketplace: Built a standalone marketplace with social login integration, allowing players to easily create a wallet and list their items for sale in both MATIC and via a fiat on-ramp.
- Unity SDK: Developed a custom SDK for the Aetheria developers to easily verify NFT ownership within the game client, enabling special visual effects for NFT holders.
- Royalty Contract: Implemented an EIP-2981 compliant royalty standard, ensuring the studio earned a 5% royalty on all secondary market sales, creating a perpetual revenue stream.
Case Study: Scalable Infrastructure for "Cyberscape" Metaverse
Industry: Metaverse & Virtual Worlds
Client Overview: A well-funded startup building "Cyberscape," a user-generated content (UGC) metaverse where players can create and monetize their own experiences and assets. They needed a robust infrastructure to support millions of NFTs and a high volume of microtransactions.
Client Testimonial: "The technical challenge was immense, and Errna delivered. They architected a Layer-2 solution that is both incredibly scalable and cost-effective. Our creators can now mint and trade assets without worrying about prohibitive gas fees." - Dr. Evelyn Reed, CTO, Cyberscape Labs
Problem
Building a metaverse on a Layer-1 blockchain like Ethereum was financially unviable due to high gas costs for minting and trading the vast number of assets required. They needed a solution that could support a thriving creator economy with near-instant and virtually free transactions.
Key Challenges
- Choosing and implementing the right Layer-2 scaling solution.
- Developing a flexible smart contract standard (ERC-1155) for diverse asset types.
- Building a high-performance indexing service to query on-chain data quickly.
- Ensuring a secure bridge for users to move assets to and from Ethereum mainnet.
Our Solution
We designed and implemented a custom infrastructure solution using a ZK-Rollup:
- ZK-Rollup Implementation: Deployed a dedicated ZK-Rollup environment, enabling massive transaction throughput with the security guarantees of Ethereum.
- ERC-1155 Smart Contracts: Developed a suite of highly optimized ERC-1155 contracts for minting both fungible (in-game currency) and non-fungible (wearables, land) assets within a single contract.
- Custom Data Indexer: Built a proprietary data indexing solution to provide a fast and reliable API for the metaverse client to fetch player inventory and asset data.
- Secure Asset Bridge: Created a trust-minimized bridge with multi-sig security for users to deposit and withdraw assets from the L2 back to Ethereum.
Case Study: Sustainable Tokenomics for "ChronoForge" P2E Game
Industry: Gaming (Play-to-Earn Strategy Game)
Client Overview: A new game studio founded by veterans from the mobile gaming industry. Their project, "ChronoForge," was a competitive strategy game with ambitious play-to-earn mechanics. They needed an expert partner to design a sustainable in-game economy that would avoid the common pitfalls of hyperinflation seen in other P2E titles.
Client Testimonial: "Errna's tokenomics team saved our project. Their models and simulations identified critical flaws in our initial design. The dual-token system they helped us build is balanced, sustainable, and has been praised by our community and investors alike." - Marcus Thorne, Head of Product, ChronoForge Studios
Problem
The studio's initial economic model was a simple, single-token system that heavily rewarded gameplay. Early simulations showed this would lead to massive inflation and a crash in token value within months of launch, destroying player trust and the game's long-term viability.
Key Challenges
- Balancing reward emissions to keep players engaged without devaluing the currency.
- Creating sufficient "sinks" (ways to spend the currency) to remove it from circulation.
- Designing a governance model that gave players a voice but protected the economy.
- Communicating a complex economic model clearly to the player base.
Our Solution
We conducted a complete overhaul of the game's economic design:
- Dual-Token Economy: Designed a system with two tokens: an uncapped utility token ($GEAR) for in-game rewards and crafting, and a capped supply governance token ($FORGE) for staking and voting.
- Dynamic Emission & Sink Modeling: Created sophisticated economic models to simulate player behavior and dynamically adjust reward rates and crafting costs to maintain a stable economy.
- Staking & Governance Module: Developed smart contracts for a staking portal where players could lock their $FORGE tokens to earn a share of marketplace revenue and vote on game proposals.
- Educational Content: Worked with the studio's marketing team to create clear articles and infographics explaining the tokenomics to the community, building trust and transparency.

Frequently Asked Questions
The "best" blockchain depends entirely on your game's specific needs. For games requiring high transaction throughput and low costs, Layer-2 solutions like Polygon, Immutable X, or Arbitrum are often ideal. We conduct a thorough analysis of your game's mechanics, player base, and decentralization requirements to recommend the perfect network for you.
This is a common concern. We implement solutions that abstract away volatility for the player. This includes integrating fiat-on-ramps that allow players to purchase using credit cards (with the crypto conversion happening in the background) and using stablecoins (like USDC) for pricing within your marketplace to provide a stable frame of reference.
Absolutely. We specialize in phased integrations that minimize disruption. We can start by creating a "bridge" that allows players to optionally mint their existing in-game items into NFTs. This allows you to introduce Web3 features gradually without forcing your entire player base to adopt wallets overnight.
ERC-721 is the standard for unique, one-of-a-kind NFTs, like a legendary sword or a specific plot of virtual land. Each token is unique. ERC-1155 is a multi-token standard that is more efficient for managing both unique items and fungible items (like crafting materials or in-game currency) within a single smart contract. We typically recommend ERC-1155 for most gaming applications due to its flexibility and gas efficiency.
This is a critical game design and tokenomics challenge. Our philosophy is to build "play-to-own" systems, not "pay-to-win." We design economies where the most powerful items can only be earned through skilled gameplay, not purchased directly. NFTs can provide cosmetic variety, early access, or convenience, but core competitive balance should always be maintained through game design.
The legal landscape is complex and varies by jurisdiction. Key considerations include whether your token could be classified as a security, AML/KYC requirements, and intellectual property rights for player-created content. While we are not a law firm, we have a network of experienced legal partners we can connect you with to ensure your project is structured for compliance from day one.
The timeline can vary based on complexity, but a typical bespoke NFT marketplace can be designed, developed, audited, and launched within 3 to 5 months. We also have white-label solutions that can accelerate this timeline if you need to get to market faster.
User experience is key. We focus on seamless onboarding. This includes integrating social logins that automatically create a wallet in the background, building intuitive in-game UIs for managing assets, and creating clear tutorials. The goal is to make the blockchain technology feel like a natural part of the game, not a technical hurdle.
Post-launch costs typically include infrastructure hosting (nodes, servers, data indexers), ongoing monitoring, and support. We offer flexible maintenance packages to fit your needs. Additionally, there will be network gas fees for certain administrative actions, though we design our systems to minimize these costs.
Yes. We can help you create and launch your own ERC-20 token to serve as the primary currency or governance token for your gaming ecosystem. This includes developing the token contract, designing the tokenomics, and assisting with the strategy for its initial distribution and listing on exchanges.
