Real-World NFT Marketplace Success Stories
Artify Collective: Empowering Digital Artists
Industry: Digital Art & Collectibles
Client Overview: Artify Collective is a startup founded by a group of established digital artists who felt constrained by the high fees and lack of curation on major public NFT platforms. Their vision was to create an exclusive, artist-centric marketplace that prioritized quality over quantity, offered significantly lower transaction fees, and provided artists with more control over their work's presentation and sale.
The Challenge
Artify needed a platform that was not only visually stunning and easy to use for non-technical artists but also highly secure and cost-effective. They had to overcome several key hurdles:
- Building a trusted platform from scratch to compete with established giants.
- Implementing a fair and transparent royalty system that artists could rely on.
- Minimizing the prohibitive gas fees of the Ethereum mainnet to attract emerging artists.
- Creating a robust curation and verification process to maintain high quality standards.
Our Solution
We partnered with Artify to build a custom NFT marketplace on Polygon, an Ethereum Layer 2 solution, to address their core needs. Our solution was a multi-faceted approach:
- Developed a custom smart contract suite for minting, sales, and royalties, which was then independently audited for security.
- Designed an elegant and intuitive UI/UX that allowed artists to easily create profiles, mint NFTs, and set up timed auctions or fixed-price listings.
- Implemented a "lazy minting" feature, allowing artists to create NFTs off-chain without any upfront gas cost, making the platform highly accessible.
- Built a secure, admin-controlled curation panel for the Artify team to review and approve artist applications, ensuring a high-quality, curated experience.
"Errna didn't just build us a platform; they built our vision. Their expertise in both blockchain and user experience was critical. We now have a thriving, low-fee ecosystem that truly puts artists first."
Legacy Gaming Inc: Forging an In-Game Asset Economy
Industry: Gaming
Client Overview: Legacy Gaming Inc. is a well-established studio with a popular AAA multiplayer title. They wanted to embrace Web3 technology to give players true ownership of their in-game assets (skins, weapons, characters) and create a vibrant, player-driven economy. Their goal was to increase player engagement, create new revenue streams, and extend the life of their flagship game.
The Challenge
Integrating a blockchain-based marketplace into a complex, existing game engine presented significant technical and user experience challenges:
- Ensuring seamless integration without disrupting the core gameplay experience.
- Handling thousands of transactions per second without high latency or fees.
- Onboarding traditional gamers who were unfamiliar with crypto wallets and blockchain.
- Preventing fraud and ensuring the security of players' valuable digital assets.
Our Solution
We engineered a hybrid on-chain/off-chain solution using a custom sidechain for scalability and a custodial wallet system for user-friendliness. This delivered a Web3 experience with Web2 convenience:
- Developed a suite of APIs to connect the game's central server with the blockchain, allowing for real-time asset minting and transfers.
- Built a white-label marketplace with a familiar "auction house" interface that was embedded directly into the game client.
- Created a custodial wallet system where players could manage their assets using their existing game logins, with an option to export to a private wallet.
- Implemented smart contracts for trading, crafting, and royalty systems, allowing players to earn from their in-game activities.
"The challenge of merging our traditional game with Web3 was immense, but Errna's team made it feel seamless. Their solution boosted player retention and opened up revenue streams we hadn't imagined."
LUXE Protocol: Authenticating Luxury Goods
Industry: Luxury Goods & Retail
Client Overview: LUXE Protocol is an enterprise consortium of luxury watch and handbag manufacturers aiming to combat the multi-billion dollar counterfeit market. Their objective was to create a unified platform where each physical item is paired with a unique "digital twin" NFT, providing an immutable record of authenticity, ownership history, and service records.
The Challenge
The solution required enterprise-grade security, scalability, and a user experience simple enough for high-end consumers and retailers. The primary challenges were:
- Designing a permissioned blockchain that multiple competing brands could trust and use.
- Creating a secure process for "twinning" a physical item with its digital NFT at the point of manufacture.
- Building a mobile-first application for consumers to easily verify authenticity and transfer ownership.
- Ensuring data privacy and compliance with international regulations like GDPR.
Our Solution
We architected and developed a permissioned blockchain solution using Hyperledger Fabric, providing the control and privacy required for an enterprise consortium. Our end-to-end solution included:
- A robust governance framework defining roles and permissions for manufacturers, retailers, and service centers on the network.
- An NFC/QR code-based system for securely linking physical items to their newly minted NFTs.
- A sleek mobile app for iOS and Android that allows owners to tap their item, view its history, and securely transfer the NFT to a new owner upon sale.
- Smart contracts that automatically record every transaction, from initial sale to secondary market trades and official servicing, creating a complete digital provenance.
"Errna delivered an enterprise-grade solution that brought our entire consortium together. Their understanding of both blockchain's potential and the demands of the luxury market was unparalleled. Counterfeiting is a huge problem, and this is a real solution."

Frequently Asked Questions
The cost varies significantly based on complexity. A white-label solution can start around $50,000, while a fully custom, multi-chain platform with unique features can range from $150,000 to $500,000+. We provide a detailed, transparent quote after an initial consultation to understand your specific requirements.
A Minimum Viable Product (MVP) using our white-label solution can be launched in as little as 6-8 weeks. A custom-built marketplace typically takes 4-6 months, depending on the complexity of the features and the number of integrations required.
The best choice depends on your priorities. Ethereum offers the largest network and highest security but has high gas fees. Layer 2 solutions like Polygon or Arbitrum offer lower fees and faster transactions while leveraging Ethereum's security. Other chains like Solana or BNB Chain offer high speed and low costs. We'll help you analyze the trade-offs and select the best platform for your specific use case.
We implement on-chain royalty standards like EIP-2981 directly into the smart contract. This ensures that creators automatically receive a percentage of the sale price every time their NFT is resold on your marketplace, and potentially on other marketplaces that respect the standard.
Security is our top priority. Our process includes: writing secure, well-tested code; following industry best practices to prevent common vulnerabilities; implementing multi-layered security architecture for infrastructure; and coordinating mandatory third-party audits for all smart contracts before deployment.
Yes, we offer comprehensive post-launch support and maintenance packages. This includes 24/7 platform monitoring, security updates, bug fixes, performance optimization, and implementing new features as your business grows and the Web3 landscape evolves.
