Success Stories in Decentralized Finance
Building a Multi-Chain Money Market from Scratch
Industry: FinTech, DeFi
Client Overview: A well-funded startup aimed to challenge established players like Aave and Compound by launching a next-generation, multi-chain lending protocol with a focus on user experience and capital efficiency. They needed a technology partner with deep DeFi expertise and the ability to deliver a highly secure platform under aggressive timelines.
"Errna was more than a vendor; they were our strategic partner. Their architects identified potential economic exploits we hadn't even considered, and their CMMI 5 process gave our investors immense confidence. We launched on time and passed two top-tier audits with flying colors."
- Alex Royce, CEO, InnovateFi
The Problem
The client had a strong vision but lacked the in-house expertise to build a complex, multi-chain DeFi protocol from the ground up. They were concerned about security risks, ensuring scalability across different EVM chains, and creating a dApp that was simple enough to attract mainstream users.
Our Solution
- Designed a modular smart contract architecture allowing for easy deployment on Ethereum, Polygon, and Avalanche.
- Integrated Chainlink Price Feeds and Proof of Reserve for robust, reliable data.
- Developed a React-based dApp with a component library that streamlined the user experience for lending, borrowing, and claiming rewards.
- Managed the end-to-end audit process with two leading security firms, coordinating remediation and re-audits.
Launching a High-Yield Farming Protocol for Stablecoins
Industry: Asset Management, Crypto
Client Overview: A crypto-native investment fund wanted to create their own yield-generating protocol to offer their limited partners (LPs) a secure, high-yield return on stablecoins. Their primary requirements were impeccable security, sophisticated reward mechanisms, and a clear dashboard for LPs to track their investments.
"Security was non-negotiable for us and our LPs. Errna's rigorous testing and audit-first approach were exactly what we needed. They delivered a rock-solid platform that has performed flawlessly since day one, generating consistent, competitive yields."
- Sarah Jenkins, Managing Partner, Quantum Capital
The Problem
The fund needed to build a protocol that was not only secure but also offered complex staking and yield farming functionalities. They were concerned about smart contract risks, creating fair and sustainable tokenomics for reward distribution, and providing a professional-grade interface for their high-net-worth clients.
Our Solution
- Developed smart contracts for multi-asset staking pools with variable lock-up periods and tiered rewards.
- Created a time-weighted reward distribution algorithm to incentivize long-term liquidity providers.
- Built a secure, private dashboard for LPs with detailed analytics on APY, total rewards earned, and portfolio value.
- Implemented a multi-signature wallet and timelock contract for administrative functions, ensuring no single point of failure.
Tokenizing Real Estate for a Private Lending Market
Industry: Real Estate, Enterprise Blockchain
Client Overview: A large commercial real estate firm wanted to innovate by creating a private, permissioned lending market for accredited investors. The goal was to tokenize fractional ownership of their properties and allow investors to use these tokens as collateral to borrow stablecoins, unlocking liquidity from traditionally illiquid assets.
"Errna masterfully bridged the gap between the complex legal world of real estate and the cutting-edge technology of DeFi. Their team understood our compliance needs and built a platform that our legal team and investors could trust. This has opened up a completely new revenue stream for our firm."
- David Chen, Head of Innovation, Pinnacle Properties
The Problem
The project involved significant legal and technical complexity. The client needed a solution that could handle permissioned access for accredited investors, integrate with legal frameworks for asset tokenization, and use reliable oracles to price unique, real-world assets (RWAs).
Our Solution
- Built the platform on a permissioned EVM-compatible chain for control and compliance.
- Integrated with a KYC/AML provider to create an on-chain identity system for whitelisting accredited investors.
- Developed a custom oracle system that aggregated data from professional appraisers and market data feeds to price the real estate-backed tokens.
- Created a legal framework in partnership with the client's counsel, embedding compliance rules directly into the smart contracts.
Our Technology Stack & Tools
We use a battle-tested stack of modern technologies and best-in-class tools to build secure, scalable, and high-performance DeFi applications.
What Our Clients Say
"The level of professionalism and deep technical knowledge at Errna is unmatched. They didn't just build our protocol; they improved it with insights that saved us from potential security flaws and significantly improved gas efficiency."
"As a non-technical founder, I needed a team I could trust completely. Errna's communication was crystal clear, and their project management was flawless. They turned my complex vision into a beautiful, functional dApp."
"We engaged Errna for a third-party security audit of our existing lending platform. Their team discovered a critical, low-level vulnerability that two other firms had missed. Their diligence is world-class. We hired them for our V2 build immediately."
