Can a Power of Attorney Give Someone Legal Access to Your Cryptocurrency?
A power of attorney is meant to let a trusted person step in and manage someone’s finances if they can’t do it themselves. Whether that authority extends to a crypto wallet depends less on the law in general and more on what the specific document actually says.
The short answer
Yes, a power of attorney can legally authorize an agent to manage cryptocurrency, but only if it explicitly addresses digital assets. Many older or generic power of attorney forms were drafted before crypto was common and may not clearly cover it. Even with clear legal authority, the agent still has to be given the practical means to access the wallet, since legal permission and technical access are two separate things.
Why the wording of the document matters so much
A power of attorney grants an agent authority over categories of property the document describes. Traditional forms often list bank accounts, real estate, and securities, but may be silent on digital assets entirely. Many states have adopted versions of the Revised Uniform Fiduciary Access to Digital Assets Act, which gives fiduciaries a legal framework for accessing digital property, but that framework generally still requires the underlying power of attorney (or account terms) to authorize that access. Without specific digital asset language, an agent may face resistance, whether from a wallet provider, an exchange, or later disputes among heirs, about whether their authority actually reaches crypto.
For this reason, an estate planning attorney familiar with digital assets is generally the right resource to review or update a power of attorney with crypto specifically in mind, rather than relying on a generic template.
Legal authority is not the same as technical access
Even a well-drafted power of attorney only grants legal permission — it doesn’t hand over a password. Crypto held in self-custody, meaning a wallet the owner controls directly rather than through an exchange, is generally only accessible with a private key or seed phrase. If the agent doesn’t know how to locate or use that information, legal authority alone won’t move any funds.
- Self-custodied wallets. Access depends entirely on the seed phrase or private key being findable and usable by the agent, since self-custody means no one else can automatically help recover a wallet.
- Exchange-held crypto. Assets held on an exchange function more like a traditional account, where the exchange’s own verification process determines whether it will honor a power of attorney, similar to how terms of service can affect rights in cases like bankruptcy.
- Hardware wallets. If crypto sits behind a device requiring a PIN, the agent will also need that PIN and the device itself, not just legal paperwork; see what a PIN code is used for on a hardware wallet.
Planning ahead makes the authority usable
Because crypto access is unusually dependent on private information, some people pair a power of attorney with a secure, separate plan for how an agent would actually locate wallet access information if it were ever needed — without storing sensitive details directly inside the legal document itself, since powers of attorney can become part of a public record in some circumstances. This is a related but distinct question from what happens after death; for that scenario, see what happens to cryptocurrency if the owner dies without sharing access.
The risks worth keeping in view
Crypto’s core risks don’t disappear just because a power of attorney exists. Transactions are irreversible once confirmed, there’s no FDIC or SIPC coverage for lost or mismanaged crypto, and a wallet’s private keys, once exposed to the wrong person, can’t be reset the way a bank password can. An agent given crypto access should understand these realities, since a mistake made under a power of attorney carries the same permanent consequences as one made by the account owner.
The bottom line
A power of attorney can be an effective tool for giving someone authority over crypto, but only when it specifically names digital assets and the agent has a practical way to access the wallet. Legal authority without access information, or access information without legal authority, both leave real gaps — the two need to work together.
