Our End-to-End NFT Gaming Services
From initial concept to scalable launch and beyond, we provide a comprehensive suite of services to bring your Web3 gaming vision to life.
Web3 Game Economy Design & Modeling
This is the foundation of a successful Web3 game. We go beyond simple token issuance to design a holistic, multi-layered economy that aligns player incentives with gameplay, ensuring long-term sustainability and preventing economic collapse.
- Dual-Token Systems: Design and implement distinct governance and utility tokens to separate economic control from in-game currency.
- Sink & Faucet Analysis: Model and balance the sources (faucets) and uses (sinks) of resources to maintain a stable and engaging economy.
- Player Archetype Modeling: Simulate how different player types (e.g., collectors, competitors, creators) will interact with your economy to ensure it's robust and fair.
Custom L2 & AppChain Development
Public blockchains are too slow and expensive for the demands of modern gaming. We build custom, high-performance blockchain environments tailored specifically to your game's needs, providing the speed and scalability required for a seamless player experience.
- Optimistic & ZK Rollups: Deploy on leading Layer-2 solutions to achieve massive scalability while inheriting the security of the mainnet.
- Cosmos SDK & Substrate: Build a sovereign, application-specific blockchain (AppChain) for complete control over your game's logic, fees, and governance.
- Gasless Transactions: Implement meta-transactions to sponsor gas fees for your players, removing a critical point of friction.
Unity & Unreal Engine SDK Integration
We bridge the gap between your game engine and the blockchain. Our custom SDKs provide a simple, powerful interface for your developers to call complex blockchain functions without needing to become Web3 experts themselves.
- Wallet & Authentication: Easily integrate non-custodial wallets and authentication flows directly within your game's UI.
- NFT Management: Provide simple functions to read player inventories, mint new items, and trigger asset transfers from in-game events.
- On-Chain Data Hooks: Create listeners that allow your game to react in real-time to events happening on the blockchain.
Smart Contract Development & Auditing
The core logic of your game's economy lives in smart contracts. We write gas-optimized, secure, and upgradeable contracts for all your on-chain needs, backed by comprehensive third-party audits to ensure asset safety.
- NFT Standards (ERC-721/1155): Develop contracts for unique and semi-fungible in-game assets.
- Token Contracts (ERC-20): Create the utility and governance tokens that power your game's economy.
- Staking & DeFi Mechanics: Build contracts for players to stake tokens, earn rewards, and participate in in-game financial activities.
In-Game & Web-Based NFT Marketplace
Enable a vibrant player-driven economy with a custom marketplace. We build platforms where players can securely trade, buy, and sell their in-game NFT assets, creating secondary market revenue for you and deeper engagement for them.
- On-Chain Order Books: Develop fully decentralized marketplaces for maximum security and transparency.
- Royalty Standard Integration: Ensure you automatically receive a percentage of every secondary sale of your game's assets.
- Fiat On-Ramp Integration: Allow players to purchase assets and currency using credit cards, dramatically lowering the barrier to entry.
Generative Asset Pipelines
Automate the creation of thousands of unique, on-chain game assets. We build systems that combine art layers with metadata to programmatically generate NFT collections for characters, items, and loot boxes.
Dynamic & Upgradable NFTs
Create assets that evolve with the player. We develop smart contracts that allow NFT metadata and properties to change based on in-game achievements, crafting, or events, keeping assets engaging and relevant.
Decentralized Identity & Soulbound Tokens
Build a persistent player reputation system. We use non-transferable Soulbound Tokens (SBTs) to represent player achievements, guild memberships, and credentials that form a lasting on-chain identity.
On-Chain Governance (DAO)
Empower your community to shape the future of the game. We set up DAO frameworks that allow token holders to vote on key decisions like balance changes, new features, and treasury management.
IPFS & Decentralized Storage
Ensure your NFT assets are truly permanent. We integrate with decentralized storage solutions like IPFS and Arweave to store NFT metadata and art, preventing broken links and ensuring assets outlive any single server.
Anti-Bot & Anti-Cheat Systems
Protect the integrity of your economy. We help implement on-chain and off-chain strategies to detect and mitigate bot activity, sybil attacks, and economic exploits, ensuring a fair playing field.
Cross-Chain Interoperability
Build for the multi-chain future. We utilize protocols like LayerZero and Chainlink's CCIP to enable your assets and tokens to move between different blockchain networks, expanding your game's reach.
On-Chain Randomness (VRF)
Guarantee provably fair outcomes for critical game events. We integrate Verifiable Random Functions (VRFs) for things like loot box drops, critical hit chances, and procedural generation, building player trust.
Indexer & Data API Development
Provide fast and reliable access to on-chain game data. We build custom indexing services and APIs that make it easy for your game client and community tools to query player balances, asset details, and transaction history.

Real-World NFT Gaming Success Stories
Launching a Scalable Economy for an Indie RPG
Client: An ambitious indie studio developing "Aetherium Chronicles," a fantasy RPG.
Problem: The studio wanted to create a deep crafting system where players could own their unique creations, but they lacked the budget and expertise to build on Ethereum mainnet. They feared high gas fees would make crafting and trading inaccessible to their players.
Key Challenges:
- Ensuring near-zero transaction costs for frequent actions like crafting.
- Creating a system for unique, player-generated items.
- Preventing early speculators from hoarding all valuable resources.
- Onboarding players who were new to cryptocurrency.
Our Solution:
We designed and deployed a full economic stack on Polygon, a leading Layer-2 solution. This involved creating a dual-token system, a smart contract for generative item crafting, and a seamless wallet onboarding flow using social logins.
"Errna didn't just build our tech; they were our strategic partners. They made Web3 feel like a native part of our game, not a bolt-on feature."
Building a Cross-Game Asset Platform for a Major Publisher
Client: A major game publisher with a portfolio of successful mobile and PC titles.
Problem: The publisher wanted to leverage its extensive IP by creating a unified ecosystem where players could own assets that were usable across multiple games. They needed a highly secure and scalable platform that could integrate with their diverse tech stacks.
Key Challenges:
- Designing a universal NFT metadata standard for different game types.
- Building a centralized bridge for moving assets between game-specific sidechains.
- Ensuring enterprise-grade security for high-value IP.
- Creating a branded, unified marketplace for all their titles.
Our Solution:
We developed a custom "hub-and-spoke" architecture using a permissioned EVM AppChain as the central hub. Each game connects as a "spoke," allowing for asset transfers through a secure, audited bridge. This gave the publisher full control while enabling true cross-game utility for players.
"The interoperability platform Errna built is foundational to our Web3 strategy. Their understanding of enterprise security and scalability was second to none."
Revitalizing a Mobile Game with Utility NFTs
Client: A mobile game studio with an established but stagnating title, "Galaxy Raiders."
Problem: The game had a loyal player base, but revenue and engagement were declining. They wanted to introduce a new layer of progression and monetization without alienating their existing Web2 audience.
Key Challenges:
- Integrating Web3 features without disrupting the existing game balance.
- Creating compelling NFT use cases beyond simple collectibles.
- Making the system accessible to a non-crypto-native mobile audience.
- Driving new user acquisition through the Web3 features.
Our Solution:
We introduced "Pilot Licenses" as dynamic NFTs that tracked player stats and unlocked special abilities. These could be leveled up and traded. We used a custodial wallet system, allowing players to participate with just their existing game login, with an option to export to a private wallet later.
"The dNFT system brought a new dimension to our game. Errna's phased approach made it easy to introduce these concepts to our community and the results speak for themselves."

Frequently Asked Questions
The timeline varies greatly depending on complexity. A simple NFT integration into an existing game might take 2-3 months. Building a full-fledged game with a complex on-chain economy and custom AppChain from scratch can take 12-18 months or more. We typically start with a 4-6 week discovery and design phase to create a detailed roadmap.
There's no single "best" one. The choice depends on your specific needs for scalability, security, and decentralization. For most games, a high-throughput Layer-2 solution like Polygon, Arbitrum, or Optimism is a great starting point. For games requiring maximum control and customization, building a dedicated AppChain using frameworks like the Cosmos SDK is often the superior long-term solution.
While we are not a law firm, we are well-versed in the evolving regulatory landscape. We build systems with compliance in mind, integrating KYC/AML checks where necessary and designing tokenomics to mitigate securities risks. We strongly advise all clients to consult with legal experts specializing in cryptocurrency and gaming, and we can connect you with trusted partners in our network.
Yes. While we have pre-built SDKs for Unity and Unreal, our team is experienced in creating custom integration layers and APIs for proprietary engines. The core principles of connecting a game client to a blockchain are universal, and we can adapt our tools to fit your specific technical environment.
Ongoing costs typically include blockchain infrastructure (node hosting, indexers), gas fees (if not subsidized), and continuous monitoring and maintenance. If you're on a shared L2, these costs are relatively low. For a custom AppChain, you will have validator and infrastructure costs. We provide detailed projections and offer managed support plans to handle all post-launch technical operations.
