Crypto Hedge Fund: Building an Automated DeFi Yield Optimization & Risk Management Platform
Industry: Investment Management
Client Overview: A mid-sized crypto hedge fund with $150M AUM was struggling to manage its complex, multi-chain DeFi strategies. Their team of analysts spent over 60% of their time manually tracking positions across dozens of protocols, calculating yields, and monitoring collateral ratios, leading to missed opportunities and increased operational risk.
Testimonial: "Errna's team built the central nervous system for our entire DeFi operation. What used to take us days of manual work now happens in real-time. Their platform gave us the confidence to scale our strategies without scaling our headcount." - Alex Royce, Chief Investment Officer, Quantum Digital Assets
Key Challenges:
- Lack of a unified view of assets spread across Ethereum, Arbitrum, and Solana.
- High risk of liquidation due to manual monitoring of collateral health.
- Inability to accurately track and attribute P&L from complex yield farming strategies.
- Significant time wasted on repetitive tasks like harvesting and compounding rewards.
Our Solution:
We developed a custom, AI-augmented platform that automated their entire DeFi workflow:
- Built a cross-chain dashboard that aggregated all positions and provided real-time P&L and risk metrics.
- Engineered an automated monitoring and alert system for collateral ratios, sending instant notifications via Telegram and email.
- Developed smart contract "bots" to automatically harvest rewards and compound yields based on pre-set parameters, optimizing for gas fees.
- Integrated an AI model to analyze protocol health and suggest optimal capital allocation across different yield farms based on risk-adjusted returns.
Family Office: A Secure, Multi-Generational Digital Asset Custody & Reporting Solution
Industry: Wealth Management
Client Overview: A single-family office with a long-term, conservative investment mandate sought to allocate a portion of its portfolio to digital assets. Their primary concerns were not high-frequency trading, but absolute security, regulatory compliance, and creating a clear, auditable framework for estate planning and inter-generational wealth transfer.
Testimonial: "Security was non-negotiable for us. Errna understood this and built a fortress. Their platform allows us to hold digital assets with the same level of confidence and governance as our traditional holdings. The reporting is impeccable." - Sophia Dalton, Managing Director, Dalton Family Office
Key Challenges:
- Extreme risk aversion to hacks, theft, or loss of private keys.
- Need for a robust governance structure with multi-level approvals for any transaction.
- Complex tax reporting and estate planning requirements for digital assets.
- Lack of in-house technical expertise to safely manage crypto infrastructure.
Our Solution:
We designed and implemented a bespoke, non-custodial asset management platform focused on security and governance:
- Integrated a Multi-Party Computation (MPC) wallet system, eliminating the concept of a single private key and its associated risks.
- Built a custom governance module with role-based access and configurable M-of-N signature policies for all outgoing transactions.
- Developed a comprehensive reporting engine that automatically generated detailed statements for accounting, tax filing, and trust administration.
- Created a secure, time-locked "inheritance" protocol via smart contracts to ensure smooth asset transfer according to the estate plan.
FinTech Platform: Launching a Real-World Asset (RWA) Tokenization Service
Industry: FinTech / Alternative Investments
Client Overview: An established FinTech company specializing in alternative investments wanted to enter the Web3 space by offering fractional ownership of private credit loans to their accredited investor base. They needed a compliant, end-to-end platform to originate loans, tokenize them, manage investors, and handle distributions.
Testimonial: "Errna was instrumental in bringing our vision for tokenized private credit to life. They handled the immense blockchain complexity, allowing us to focus on what we do best: sourcing and underwriting quality assets. Their platform is the backbone of our new business line." - Jace Holloway, CEO, Liquid Alpha Investments
Key Challenges:
- Navigating the legal and technical complexities of issuing security tokens.
- Building a seamless onboarding and investment workflow for non-crypto-native investors.
- Ensuring on-chain transactions and ownership records were always synchronized with off-chain legal agreements.
- Automating the process of collecting fiat loan payments and distributing yields to token holders in stablecoins.
Our Solution:
We built a full-stack RWA tokenization platform with a focus on compliance and user experience:
- Developed a compliant ERC-3643 security token standard with built-in transfer restrictions and identity verification.
- Created a user-friendly investor portal with integrated KYC/AML checks and a DocuSign-powered subscription process.
- Built a "dual ledger" system that used Oracles to link on-chain token ownership to an immutable off-chain database of legal records.
- Engineered a smart contract-based waterfall to automatically collect payments and distribute monthly yields to token holders' wallets.

Frequently Asked Questions
Security is our top priority and is embedded in our entire development lifecycle. We employ a multi-layered approach: 1) Secure Architecture: We design systems with defense-in-depth, utilizing technologies like MPC and smart contract wallets to eliminate single points of failure. 2) Code Audits: Our process includes rigorous internal code reviews and integration of automated static analysis tools. We also facilitate independent third-party audits. 3) Best Practices: We strictly adhere to industry best practices like the Smart Contract Security Verification Standard (SCSVS). 4) Continuous Monitoring: Post-deployment, we implement real-time threat detection and incident response plans. 5) Process Maturity: Our CMMI Level 5 and SOC 2 compliant processes ensure that security is a repeatable, verifiable part of our delivery.
We specialize in building non-custodial platforms where the end-user always retains full control of their private keys and assets. This is the gold standard for security and trust in the Web3 space, as it eliminates counterparty risk. However, for clients with specific regulatory or operational needs, we have the expertise to integrate with qualified third-party custodians or build compliant, segregated custodial solutions.
The timeline varies depending on the complexity and scope of the project. A Minimum Viable Product (MVP) with core features like portfolio tracking, wallet integration, and basic reporting can typically be developed in 3-4 months. A full-featured institutional platform with advanced DeFi integrations, AI analytics, and comprehensive compliance modules may take 6-12 months. We accelerate this process by leveraging our existing library of pre-built, audited components.
We build with a "compliance-by-design" philosophy. We work closely with your legal and compliance teams to understand the specific regulatory requirements of your jurisdiction. Our platforms are built with modular compliance layers, allowing for the integration of leading KYC/AML providers (like Chainalysis, Elliptic), implementation of transaction monitoring rules, and generation of reports required by bodies like the SEC, FinCEN, and others.
We offer flexible engagement models to suit your needs. Our most common model is the Dedicated Team, where we provide a full, cross-functional team of developers, project managers, and QA engineers who work exclusively on your project. We also offer Staff Augmentation to supplement your existing team and Project-Based models for well-defined scopes. All engagements begin with a deep discovery phase to align on goals, followed by an agile development process with transparent, weekly sprints and regular communication.
Absolutely. We understand that digital assets are part of a broader portfolio. We specialize in building secure APIs and data bridges to connect your Web3 platform with your existing portfolio management systems (PMS), accounting software (e.g., QuickBooks, Xero), and customer relationship management (CRM) platforms. This ensures a seamless flow of information and a holistic view of all assets, both digital and traditional.
