In 2022, the American Bar Association (ABA) issued a landmark Formal Opinion addressing lawyers' ethical obligations when dealing with cryptocurrencies and digital assets. This guide explains what the opinion says, how to assess compliance in your practice, and the most common traps to avoid.
The American Bar Association (ABA) Standing Committee on Ethics and Professional Responsibility issued Formal Opinion 498 (often referred to as the "cryptocurrency opinion") in 2022. It provides guidance to lawyers on their professional responsibilities when handling matters that involve digital assets, including cryptocurrency, NFTs, and other blockchain‑based property.
The opinion was developed in response to the growing prevalence of cryptocurrency in legal practice—whether as an asset subject to discovery, a form of payment for legal services, or the subject of estate planning, litigation, or business transactions. The ABA recognised that existing ethical rules needed to be interpreted in the context of this new technology.
The opinion applies to all lawyers admitted to practice in jurisdictions that have adopted the ABA Model Rules of Professional Conduct. While the opinion itself is not binding law, it is highly influential and is frequently cited by state bar ethics committees and courts.
The ABA Opinion rests on several key principles that lawyers must integrate into their practice when engaging with digital assets.
The opinion confirms that cryptocurrency and other digital assets are forms of property under the Model Rules. This means they must be treated with the same care and diligence as traditional assets, including when they are held in trust, subject to seizure, or transferred as part of a transaction.
Lawyers have a duty to maintain the requisite knowledge and skill to handle matters involving cryptocurrency. This may require staying informed about blockchain technology, wallet mechanics, and the regulatory landscape. If a lawyer lacks expertise, they must either consult with an expert or decline the representation.
The opinion emphasises that the transparent, immutable nature of blockchain does not override the duty of confidentiality. Lawyers must take reasonable steps to prevent the disclosure of client information, which may involve using privacy‑enhancing techniques, selecting appropriate blockchains, or advising clients on the public nature of certain transactions.
Lawyers must be alert to potential conflicts that arise when they or their firm hold cryptocurrency that is related to a client's matter. The opinion advises caution when a lawyer's personal or firm interests in digital assets could conflict with a client's interests.
Evaluating your compliance with the ABA Opinion involves a systematic review of your firm's policies, procedures, and individual competencies.
Assess whether you and your colleagues have the necessary knowledge to handle cryptocurrency matters. This includes understanding how transactions are recorded, the difference between hot and cold wallets, and the tax and regulatory implications of digital assets.
Update your conflict‑checking systems to capture cryptocurrency holdings, investments, or interests. For larger firms, this may involve periodic disclosure requirements for attorneys and staff.
Consider including specific terms in engagement letters that address the handling of cryptocurrency, including the risks of volatility, the public nature of blockchain data, and the client's responsibilities for securing their own private keys.
Ensure that your firm's technology infrastructure—including email, document management, and secure communication tools—is adequate to protect client information related to cryptocurrency matters.
The opinion elaborates on three central ethical duties that lawyers must navigate when cryptocurrency is involved.
Competence in the context of cryptocurrency means understanding the practical and legal implications of digital assets. This includes:
The opinion highlights the tension between blockchain's transparency and the duty to keep client information confidential. Lawyers should:
The opinion advises that lawyers who hold cryptocurrency may face conflicts if their holdings could affect their professional judgment. Disclosure and consent may be required in certain circumstances. The opinion also warns about the potential for conflicts when lawyers serve as custodians or trustees of digital assets.
Implementing the ABA Opinion's guidance requires concrete actions. The following steps can help your firm align with its recommendations.
Provide regular training sessions for lawyers and support staff on cryptocurrency fundamentals, emerging legal issues, and relevant regulatory updates. Consider designating one or more attorneys as "subject matter experts" in digital assets.
Draft internal policies that address:
Ensure that clients are adequately informed about the risks and implications of using cryptocurrency in their legal matters. This should be part of the initial engagement process and revisited as circumstances change.
Consider partnering with reputable blockchain analytics firms, custody providers, or legal technology vendors that specialise in digital assets. These partnerships can help you fulfill your duty of competence and safeguard client information.
The ABA Opinion is influential, but it is not the only guidance available. Different jurisdictions and organisations have taken varying approaches. The table below highlights key differences.

Use this checklist to assess and enhance your compliance with the ABA Formal Opinion on Cryptocurrency.
While the ABA Opinion provides valuable guidance, it is important to recognise its limitations.
Formal opinions are not laws. They are interpretive guidance that state bars and courts may consider, but they do not carry the force of statutory or regulatory authority. Actual compliance is determined by the rules of your specific jurisdiction.
The opinion was issued in 2022. Since then, the cryptocurrency and blockchain landscape has evolved significantly. New developments—such as the growth of DeFi, stablecoins, and regulatory changes—may not be fully addressed by the opinion.
Different states and countries have adopted different interpretations of ethical rules. The ABA Opinion may be more or less influential depending on your jurisdiction. Always consult local rules and opinions.
