Success Stories: Real-World Impact
Explore how we've helped businesses like yours launch successful Web3 marketplaces.
ArtDeFiance: A Curated NFT Marketplace for Digital Artists
Client Overview: ArtDeFiance is a startup founded by a collective of established digital artists who wanted to create a curated, high-end marketplace to combat the noise and low-quality art on larger platforms. They needed a platform that was not only visually stunning but also offered robust royalty features and a strong sense of community.
The Problem: The client needed a bespoke NFT marketplace that could handle timed auctions, enforce creator royalties automatically, and provide a seamless user experience for both artists and non-crypto-native collectors. Security and scalability were paramount concerns.
Key Challenges:
- Implementing a complex, on-chain royalty system that was both fair and gas-efficient.
- Designing a UI that was elegant and intuitive for users unfamiliar with blockchain technology.
- Ensuring the platform could scale to handle high traffic during popular collection drops.
- Integrating a fiat-to-crypto on-ramp to lower the barrier to entry for new collectors.
Our Solution:
We developed a full-stack solution on the Polygon network to ensure low transaction fees. Our team engineered a custom ERC-721 smart contract with a robust, upgradeable royalty standard. We built a React-based front-end with a clean, gallery-like feel and integrated a third-party payment gateway to allow purchases with credit cards.
"Errna didn't just build a platform; they built our vision. Their technical expertise and strategic insights were invaluable. They are true partners."
Fraction Estate: Democratizing Real Estate Investment
Client Overview: Fraction Estate is a FinTech company aiming to disrupt the real estate investment market. Their goal was to create a platform where property owners could tokenize their assets and sell fractional ownership to a global pool of investors, making real estate investing more accessible and liquid.
The Problem: The client faced significant technical and regulatory hurdles. They needed a legally compliant platform to tokenize real-world assets, a secure marketplace for secondary trading of these tokens, and a system to automate dividend distribution to token holders.
Key Challenges:
- Ensuring compliance with securities regulations (e.g., KYC/AML) for all investors.
- Developing a secure and reliable process for linking digital tokens to legal ownership of physical properties.
- Creating a liquid secondary market to attract and retain investors.
- Automating the calculation and distribution of rental income to thousands of token holders.
Our Solution:
We built a comprehensive RWA tokenization platform on Avalanche. The solution included an investor onboarding portal with integrated KYC/AML checks, a primary issuance module for property tokenization, and a decentralized exchange for secondary trading. We developed smart contracts to automatically distribute monthly rental income to token holders based on their ownership percentage.
"The complexity of our project was immense, but Errna's team handled it with exceptional professionalism. Their compliance-first approach gave us the confidence to launch."
SupplyBlock: A B2B Marketplace for Ethical Sourcing
Client Overview: SupplyBlock is an enterprise client in the fashion industry focused on promoting sustainable and ethical manufacturing. They wanted to create a private, permissioned marketplace to connect brands with verified, ethically-certified material suppliers and manufacturers.
The Problem: The client needed a platform that could provide an immutable record of a material's journey through the supply chain. The system had to be secure, private, and capable of handling complex multi-party transactions and documentation verification.
Key Challenges:
- Ensuring data privacy while providing transparency to authorized parties.
- Creating a digital "passport" for each batch of material that was tamper-proof.
- Integrating with existing enterprise ERP systems for seamless workflow.
- Onboarding and verifying hundreds of global suppliers with varying technical capabilities.
Our Solution:
We built a B2B marketplace using Hyperledger Fabric, a permissioned blockchain framework. Each supplier and brand was a node in the network. We developed "chaincode" (smart contracts) to manage the entire lifecycle of an order, from PO issuance to final delivery, with each step recorded on the ledger. We also created a system for uploading and verifying ethical certifications as NFTs.
"Errna delivered a transformative solution. The transparency and efficiency gains from our new marketplace have given us a significant competitive advantage in the sustainable fashion space."

Frequently Asked Questions
Have questions? We have answers. Here are some common inquiries about Web3 marketplace development.
How much does it cost to build a Web3 marketplace?
The cost varies significantly based on complexity, features, and the chosen blockchain. A simple NFT marketplace MVP might start around $50,000, while a complex DeFi or RWA platform with extensive compliance features could cost $250,000 or more. We provide a detailed, transparent quote after our initial discovery phase.
How long does the development process take?
A typical timeline for an MVP is 3-6 months. More complex platforms can take 6-12 months or longer. Our process is designed to launch a core, functional product as quickly as possible, followed by iterative improvements based on user feedback.
Which blockchain is best for my marketplace?
The best choice depends on your specific needs regarding transaction speed, cost, security, and ecosystem. Ethereum is the most established, but Layer-2 solutions like Polygon and Arbitrum, or other Layer-1s like Solana and Avalanche, offer compelling advantages in speed and cost. We'll help you make an informed decision based on your project's unique requirements.
How do you ensure the security of the smart contracts?
Security is our top priority. Our process includes: writing code based on industry best practices (e.g., Checks-Effects-Interactions pattern), extensive internal peer reviews, comprehensive testing with tools like Hardhat and Truffle, and a mandatory third-party security audit from a reputable firm before any mainnet deployment.
Can you help with tokenomics and whitepaper creation?
Yes. Our service is end-to-end. During the initial strategy phase, our experts will work with you to design a sustainable tokenomics model that aligns incentives for all participants. We can also assist in drafting a professional, comprehensive whitepaper that clearly articulates your vision, technology, and economic model to potential users and investors.
What happens after the marketplace is launched?
Our partnership doesn't end at launch. We offer flexible post-launch support and maintenance packages that include security monitoring, server management, bug fixes, and ongoing development for new features. We are committed to the long-term success and growth of your platform.
