Offshore Trusts and Cryptocurrency

Cryptocurrency is uniquely vulnerable to court-ordered seizure. Unlike a bank account, where a creditor must serve a writ of garnishment on a financial institution, cryptocurrency can be transferred by anyone who controls the private keys. Courts treat private keys like any other asset under the debtor’s control and can order their surrender under threat of contempt. If the debtor holds the keys personally, there is no institutional intermediary to slow the process or create procedural barriers.

This makes cryptocurrency one of the asset classes where offshore trust protection has the most practical impact. The core mechanism is the same as with any other asset: the trust transfers legal ownership to a foreign trustee who is not subject to U.S. court jurisdiction. But the specific way cryptocurrency is held within the trust structure matters more than it does with traditional financial assets, because custody of digital assets involves operational decisions that affect both security and legal protection.

Why Cryptocurrency Needs Structural Protection

Many cryptocurrency holders assume that the decentralized nature of digital assets provides inherent protection. It does not. Blockchain transactions are pseudonymous, not anonymous. Exchanges are subject to subpoenas and routinely comply with court orders. The IRS requires disclosure of cryptocurrency holdings on tax returns. And in litigation, a debtor must disclose all assets under oath, including digital assets held in personal wallets, on exchanges, or in cold storage.

A creditor who obtains a judgment can ask the court to order the debtor to transfer cryptocurrency directly. If the debtor refuses, the court can hold the debtor in contempt. Because private keys can be stored on a device, on paper, or memorized, courts are aggressive about enforcement. There is no institutional gatekeeper to argue with. The debtor either transfers the funds or faces sanctions.

Domestic asset protection structures do not solve this problem effectively. A domestic LLC or a self-settled domestic trust remains within U.S. court jurisdiction. The court can order the manager or trustee to transfer the cryptocurrency, and the manager or trustee must comply. The structural protection that an offshore trust provides is the removal of the custodian from U.S. jurisdiction entirely.

How the Structure Works

Most offshore trust structures for cryptocurrency use a layered approach: the trust owns an offshore LLC, and the LLC holds the cryptocurrency. The settlor serves as manager of the LLC during normal circumstances, retaining day-to-day control over trading, staking, and wallet management. If litigation arises, management authority shifts to the offshore trustee or a replacement manager outside U.S. jurisdiction.

This structure serves two purposes. First, it preserves the settlor’s ability to manage the assets actively without requiring trustee approval for every transaction. Cryptocurrency holders who trade frequently or participate in decentralized finance protocols need operational flexibility that direct trustee custody does not easily accommodate. Second, it creates a clean legal separation: the LLC, not the settlor, owns the cryptocurrency, and the trust, not the settlor, owns the LLC.

The alternative is direct trustee custody, where the offshore trustee holds the private keys or controls the wallets. This provides the strongest legal separation but limits operational flexibility. Some Cook Islands trustee companies have partnered with institutional custodians that specialize in digital asset storage, including multi-signature wallets and cold storage vaults. This approach works best for clients who hold cryptocurrency as a long-term investment rather than as an actively traded portfolio.

Custody Considerations

The custody question is the practical challenge that distinguishes cryptocurrency from other assets held in offshore trusts. With securities or cash, the trustee opens an account at a foreign bank or brokerage, and custody is straightforward. With cryptocurrency, custody involves private key management, wallet security, and decisions about storage methods that directly affect both the security and accessibility of the assets.

There are three common approaches.

The first is institutional custody through the trustee’s banking relationships. Some offshore banks and specialized custodians in Switzerland and Liechtenstein will store private keys in secure vaults and manage digital asset portfolios on behalf of trust clients. This is the most secure option but also the most expensive, and it limits the settlor’s ability to manage the assets directly. Annual custody fees for institutional digital asset storage typically add $1,000 to $2,000 or more to the trust’s operating costs.

The second is LLC-managed custody, where the offshore LLC holds the wallets and the settlor manages the keys as LLC manager. This preserves flexibility but creates a practical tension: if the settlor holds the keys personally, a U.S. court may argue that the settlor has the ability to transfer the assets regardless of the trust structure. The legal answer is that the settlor holds the keys in a fiduciary capacity as LLC manager, not as personal property, but this distinction is stronger when the management structure is well-documented and the trust deed clearly addresses digital asset custody.

The third is cold storage within the LLC structure, where hardware wallets or other offline storage devices are held by the LLC. This provides strong security against both hacking and exchange failure while keeping the assets within the trust’s legal framework. The cold storage devices themselves should be documented as LLC property, and backup procedures should account for the possibility that management authority will shift to the trustee if litigation triggers the trust’s protective provisions.

Across all three approaches, multi-signature wallet arrangements can add an additional layer of both security and legal separation. A typical configuration uses a two-of-three key structure: one key held by the settlor (or the LLC manager), one held by the offshore trustee, and one held by an independent third-party custodian or stored in a secure vault. No single party can move funds unilaterally, which strengthens the argument that the settlor does not have unilateral control over the assets. It also solves the succession problem that plagues individual crypto holders, because if one key holder becomes incapacitated or unavailable, the remaining two can still authorize transactions. The cost of implementing a multi-signature arrangement varies but typically falls within the institutional custody fee range discussed above.

What the Trust Does Not Solve

An offshore trust does not make cryptocurrency invisible. All cryptocurrency held in an offshore trust must be reported to the IRS. The trust itself requires Forms 3520 and 3520-A. If the trust holds accounts at foreign financial institutions, FBAR filing is required. Cryptocurrency exchanges that perform KYC verification maintain records that connect wallet addresses to identifiable persons. The protection an offshore trust provides is legal, not informational. The creditor will know the cryptocurrency exists. The trust prevents the creditor from reaching it through U.S. court processes.

An offshore trust also does not protect against exchange failure. If cryptocurrency is held on a centralized exchange and that exchange collapses, the trust structure does not create a priority claim over other exchange creditors. The FTX collapse demonstrated this risk clearly. Cryptocurrency held in self-custody wallets owned by the trust’s LLC avoids this exposure entirely, which is one reason most offshore planning for digital assets emphasizes self-custody over exchange-based storage.

The bankruptcy analysis applies to cryptocurrency held in trust just as it applies to any other trust asset. The ten-year look-back under Section 548(e) does not distinguish between asset types. Cryptocurrency transferred to the trust within the avoidance window is subject to the same risks as any other transfer.

Additional Costs

Holding cryptocurrency in an offshore trust increases the cost of the structure compared to holding only traditional financial assets. Trustee companies that accept digital assets typically charge higher fees because of the additional due diligence, custody arrangements, and compliance requirements involved. Expect an additional $2,000 to $5,000 in setup costs for cryptocurrency-specific custody arrangements and $1,000 to $2,000 in additional annual fees.

These costs are in addition to the base trust setup and annual costs and the standard IRS reporting requirements that apply to all offshore trusts. Clients holding cryptocurrency as a significant portion of their portfolio should factor these costs into the overall planning analysis.

When It Makes Sense

Offshore trust protection for cryptocurrency is most appropriate for clients who hold substantial digital asset portfolios and face meaningful litigation exposure. The added cost and complexity of structuring cryptocurrency within an offshore trust is difficult to justify for holdings below $500,000, particularly when annual custody and compliance costs can reach $3,000 to $5,000 above the base trust expenses.

For clients with larger portfolios and real creditor risk, the combination of an offshore trust and a properly structured LLC provides protection that no domestic arrangement can match. The key is getting the custody structure right from the beginning, because retrofitting a trust to accommodate cryptocurrency after litigation has started creates exactly the kind of timing and transfer issues that undermine asset protection planning.
