Regulatory Framework & Strategy Development
We design a comprehensive compliance strategy tailored to your specific business model, target markets, and technology stack. This foundational work ensures compliance is an integrated part of your operations, not an afterthought.
- Develop a clear roadmap for achieving and maintaining regulatory compliance across all relevant jurisdictions.
- Establish internal policies and controls that align with global best practices and specific legal requirements.
- Create a scalable framework that can adapt to new products, markets, and evolving regulations.
KYC/AML & CTF Program Implementation
We help you design and implement a robust Anti-Money Laundering (AML) and Counter-Terrorist Financing (CTF) program, including Know Your Customer (KYC) protocols, to protect your platform from illicit activities and meet regulatory obligations.
- Integrate leading KYC/AML software solutions for identity verification and risk scoring.
- Implement transaction monitoring systems (like Chainalysis or Elliptic) to detect and report suspicious activity.
- Ensure compliance with the FATF Travel Rule for Virtual Asset Service Providers (VASPs).
Securities Law Compliance & Howey Test Analysis
Navigating securities law is one of an crypto project's most critical challenges. We provide expert analysis to determine if your token could be classified as a security and structure your offering to minimize regulatory risk.
- Conduct in-depth Howey Test analysis for your token and business model.
- Advise on tokenomics and utility design to strengthen your token's non-security characteristics.
- Guide you through the requirements for Security Token Offerings (STOs) if applicable.
Smart Contract Compliance Audits
Beyond security vulnerabilities, your smart contracts must align with your legal and compliance obligations. We audit your code to ensure it functions as intended and doesn't create unintended regulatory liabilities.
- Verify that smart contract logic accurately reflects your stated business rules and legal disclaimers.
- Assess data handling within smart contracts for compliance with privacy laws like GDPR.
- Ensure automated processes do not violate financial regulations or consumer protection laws.

The Problem
The client needed to launch in three different jurisdictions, each with unique licensing requirements and AML regulations. Their team was strong on tech but lacked the expertise to build an institutional-grade compliance program that would satisfy regulators and banking partners.
Key Challenges
- Navigating complex and conflicting international VASP licensing laws.
- Implementing a cost-effective yet robust KYC and transaction monitoring system.
- Securing fiat banking partnerships, which required proof of a strong compliance framework.
- Training their team on ongoing compliance operations.
Our Solution
We developed a multi-phase strategy:
- Conducted a jurisdictional analysis to create a prioritized licensing roadmap.
- Designed and helped implement a full KYC/AML program, integrating third-party tools for identity verification and blockchain analytics.
- Crafted a comprehensive set of compliance policies and procedures to present to regulators and banking partners.
- Provided hands-on training for their newly appointed Compliance Officer and support team.
The Problem
The client's ambitious project involved multiple international partners sharing sensitive operational data on a permissioned blockchain. Their legal team raised significant concerns about GDPR and data privacy, as some data, once written, could not be erased.
Key Challenges
- Reconciling the "right to be forgotten" under GDPR with the immutability of blockchain.
- Defining data ownership and access rights among consortium members.
- Ensuring the solution didn't violate cross-border data transfer regulations.
- Managing commercially sensitive information on a shared ledger.
Our Solution
Our approach focused on a "privacy by design" architecture:
- Advised an off-chain data storage model, where only hashes of sensitive data were stored on-chain, allowing for off-chain data deletion.
- Utilized zero-knowledge proofs to enable verification of data without revealing the underlying sensitive information.
- Developed a comprehensive governance framework and multi-party legal agreement for the consortium.
- Structured the system to comply with data localization and international transfer laws.
The Problem
The team wanted to distribute a governance token to their community to decentralize control of the protocol. They were deeply concerned that the token could be deemed a security by the SEC, exposing them to significant legal liability.
Key Challenges
- Structuring the token's rights and functions to avoid the prongs of the Howey Test.
- Planning a fair and compliant token distribution (airdrop) event.
- Establishing a legal wrapper or foundation for the resulting DAO.
- Mitigating the personal liability of the core developers.
Our Solution
We provided a strategic legal and structural framework:
- Conducted a detailed analysis of their proposed tokenomics and recommended key changes to emphasize governance and utility over profit expectation.
- Provided a legal opinion memorandum on the token's regulatory status based on the revised structure.
- Advised on the setup of a Swiss Foundation to oversee the protocol's treasury and limit developer liability.
- Developed terms of service and risk disclosures for the protocol's interface and airdrop claim process.

What Our Clients Say
Trust is earned through results. Here's what our partners say about our work.
Working with Errna was the best decision we made pre-launch. Their guidance on our AML program was instrumental in securing our banking relationships. They are true partners, not just consultants.
The regulatory landscape for DeFi is a minefield. Errna provided a clear, pragmatic framework that allowed us to innovate responsibly. Their technical depth is unmatched in the legal space.
As a CCO, I needed a partner who could translate blockchain risk into a language our board could understand. Errna's risk assessment was thorough, professional, and, most importantly, actionable.
Frequently Asked Questions
While traditional law firms are excellent, they often lack the deep technical understanding of how blockchain works. Compliance in this space isn't just about interpreting law; it's about applying it to novel technologies like smart contracts and decentralized networks. We bridge that critical gap between legal theory and technical reality, preventing advice that is legally sound but technologically impractical or impossible to implement.
This is one of the most critical and complex questions in the space. The answer depends on a detailed analysis of your token's characteristics, your marketing, and the overall ecosystem, typically evaluated against the SEC's Howey Test. Our service includes a comprehensive analysis to assess the risk and help you structure your token to function as a true utility, strengthening its non-security classification.
The right time is from day one. Building compliance into your project's DNA is exponentially cheaper and more effective than trying to "bolt it on" later. Early compliance builds trust with users, attracts serious investors, and prevents catastrophic pivots or shutdowns down the road. It's a foundational investment in your long-term success.
Our team is dedicated to continuous monitoring of the global regulatory landscape. We subscribe to specialized intelligence services, participate in industry policy groups, and maintain a network of legal contacts in key jurisdictions. For our retainer clients, this ongoing intelligence is a core part of our service, ensuring your compliance framework evolves with the market.
