Cryptocurrency is, in certain respects, more vulnerable to seizure than traditional financial assets — and that vulnerability comes from the same properties that make it appealing. Unlike a bank account, which requires a court to serve process on a domestic institution, crypto held on a centralised US exchange can be seized by directing the exchange to freeze and transfer the balance. US-based exchanges are domestic entities subject to US court authority, and they respond to court orders like any other domestic financial institution.
Self-custodied crypto — held in a personal wallet with the settlor holding the private keys — is not immune either. A court can order the settlor to produce the private keys, and a settlor who refuses faces contempt exposure for the same reason anyone refuses a court order. The underlying asset may be technically borderless, but the person who controls it is not.
Placing cryptocurrency into a Cook Islands Trust doesn’t change the nature of the asset — what it changes is who controls it. Once the trust or its underlying LLC holds the asset, a judgment creditor’s path to recovery runs through the Cook Islands trustee, not through the settlor directly, and the trustee has no legal obligation to comply with a US court order.
How crypto is held within the structure depends on whether it’s on a centralised exchange, in a self-custodied wallet, or in some combination of the two — and the three main custody approaches for trust-held crypto each have different operational characteristics.
Exchange-held custody. Crypto sitting on a centralised exchange transfers by moving the exchange account — or by withdrawing to a wallet address controlled by the LLC — into the offshore structure. The most straightforward approach for crypto held at an exchange is to open an exchange account in the LLC’s name (where the exchange allows entity accounts) and transfer the holdings there, placing them under the LLC’s control rather than the settlor’s personal account. Not all exchanges allow entity accounts, which may require withdrawing to a self-custodied wallet first and then retransferring.
Self-custodied wallet transfer. Crypto in a personal wallet transfers to the LLC by sending it to a wallet address that the LLC controls, with private keys documented and held appropriately within the trust structure. This requires specific documentation of the transfer — blockchain transaction records, valuation at the time of transfer for Form 3520 reporting — and clear protocols for ongoing key management. The trustee needs to have, or be able to obtain, actual control of the wallet under the trust’s duress clause if it ever activates; a wallet the settlor controls exclusively can’t be taken over by the trustee in the way an LLC’s bank account can.
Multi-signature arrangements. Multi-signature wallet structures require more than one party’s approval to authorise any transaction. For a Cook Islands Trust, this can be structured to require both the settlor (as LLC manager, for day-to-day operational authority) and the trustee (for any transaction above a defined threshold, or as a confirmation layer) to approve transfers. This mirrors the trust’s broader dual-control architecture — operational control day-to-day, trustee oversight and override capability when it matters.
Not every Cook Islands trustee is equipped to handle cryptocurrency, and this is one of the most important practical checks before selecting a trustee for a structure where crypto represents significant wealth. Questions to confirm directly with any prospective trustee include: whether they will accept crypto assets into the trust at all; how they handle private key custody and documentation; what their process is for taking control of a wallet if the duress clause activates; and whether they have experience with the tax reporting involved in crypto held through a foreign grantor trust.
Ora Partners, among the Cook Islands’ licensed trustee companies, has invested specifically in blockchain-based administration infrastructure and has built procedures specifically for digital asset custody within trust structures. For settlors whose crypto holdings are a significant share of their total wealth, trustee selection matters as much as the trust structure itself.
The transfer of crypto into the trust is itself a reportable event for Form 3520 purposes — the same way any asset transfer to a foreign trust must be reported. The crypto’s fair market value at the time of transfer is the figure that goes on the form, and blockchain transaction records providing a timestamped, independently verifiable record of the transfer are the documentation to retain for that purpose.
Ongoing gains and disposals within the trust flow through to the settlor’s personal return as they would for any other trust-held asset, since the Cook Islands Trust is treated as a foreign grantor trust and the settlor is treated as the tax owner of everything in it. Crypto trading within the trust doesn’t change the tax treatment of individual transactions — gains are still gains, and they’re still the settlor’s gains for US tax purposes. We refer all detailed tax and reporting questions to a qualified CPA with offshore trust and cryptocurrency experience.
