Generally, do not put a wallet address in your operating agreement, and avoid listing cold-wallet device IDs or serial numbers there too. An OA is routinely shared with banks, custodians, and courts, creating privacy, security, and staleness risks. Reference digital assets by category, then maintain a separately-controlled, access-restricted asset schedule. How the operating agreement should reference digital assets is covered in detail in crypto LLC formation.
What Is an Operating Agreement Asset Schedule?
An operating agreement asset schedule is a separate, attached exhibit that lists the specific assets an LLC owns at a given point in time. Unlike the operating agreement itself, which governs member rights, management authority, and governance rules, the schedule is updated independently, can be notarized on its own timeline, and does not need to be filed publicly or shared wholesale with third parties.
For Wyoming LLCs holding crypto assets, the distinction between what belongs in the operating agreement and what belongs in a controlled schedule is a material security and governance decision.
Should I List Wallet Addresses in the Operating Agreement?
Not directly in the OA body, and generally not even in an attached exhibit if that exhibit will be shared with financial institutions.
Here is why. When your LLC opens a bank account, applies for custody at an institution, or becomes involved in a legal proceeding, the operating agreement is routinely produced to third parties. Wallet addresses appearing in that document:
- Become associated with your legal identity in contexts you cannot fully control
- Create a persistent link between your entity and specific on-chain activity visible on public block explorers
- Become stale the moment you migrate assets to a new address, requiring an OA amendment each time
The stronger approach: the operating agreement references digital assets by category ("Bitcoin and other Tier-1 digital assets," "ERC-20 governance tokens") and attaches or references a separate, access-controlled wallet inventory that is updated on its own schedule and shared only with signatories, custodians, or legal counsel who need it.
If your situation requires documenting that the LLC owns specific addresses as of a specific date, for example, to document a contribution event, use a notarized contribution memo or a separate asset assignment agreement rather than embedding address strings in the OA. Drafting these documents is a legal service: DAG coordinates with your attorney, but the drafting itself should be done by qualified legal counsel.
Should I List Cold Wallet Device Serial Numbers in the Operating Agreement?
No. Device serial numbers belong in neither the operating agreement nor any attached schedule that will be shared with third parties.
Why device details create risk without legal benefit:
- Knowing the hardware model and serial number tells an adversary what device you use, potentially when it was purchased, and details that assist targeted social engineering or physical theft
- Custody of a hardware device does not equal legal ownership of the assets on-chain, the serial number proves nothing in a dispute
- Devices change: you may migrate from self-custody to institutional crypto custody, or upgrade hardware, without the underlying wallet addresses changing
The operating agreement can establish custody standards without naming specific devices: "Cold storage is required for holdings above $[threshold]. Exchange custody may not exceed working balances required for active trading." This creates enforceable governance rules without locking the LLC into particular hardware.
What Should Go IN the Operating Agreement vs. What Stays in a Separate Schedule?
Put this in the operating agreement:
- Asset categories the LLC is authorized to hold (e.g., Bitcoin, Ethereum, stablecoins, governance tokens)
- Signing authority: who may initiate transfers, single-sig vs. multi-sig thresholds
- Transaction approval requirements by size tier
- Custody standards: cold storage minimums, prohibition on unsanctioned exchange custody
- Succession language: who succeeds to signing authority and the general process for key recovery (no specifics)
- Reference to a separately-maintained asset schedule, updated and notarized independently
Keep in a separately-controlled, access-restricted asset schedule or secure letter of instruction:
- Specific wallet addresses and which assets each holds
- Approximate balances as of each schedule date (notarize separately for timestamping)
- Custody method per address (self-custody, Cryptocurrency qualified custodians have emerged to serve institutional requirements. Qualified custody may be required for register">qualified custodian, MPC)
- Hardware wallet model (if operationally necessary, not serial numbers)
- Location of devices or storage media (in general terms only, in a document restricted to succession contacts)
Never include anywhere that may be shared:
- Private keys or seed phrases
- PIN codes or passphrase extensions
- Specific physical location of storage devices
- Shamir shares or key escrow part assignments (describe the process in the OA; store the parts separately)

Related Questions
Does Wyoming law require an LLC to document its digital asset holdings?
Wyoming's Title 17 LLC Act requires LLCs to maintain adequate books and records of the company's business and financial condition (Wyo. Stat. § 17-29-410). For a crypto-holding LLC, that includes records sufficient to establish what assets the company owns and when contributions were made. A notarized asset schedule updated at each material contribution satisfies this standard and creates useful timestamped evidence without embedding sensitive details in the operating agreement.
Can the asset schedule be used as evidence of LLC ownership in a dispute?
A notarized schedule attached to or formally referenced by the operating agreement can support a claim of LLC ownership, particularly when the blockchain record confirms the listed addresses hold the assets on the stated date. It is corroborating documentation, not independently determinative. An attorney experienced in digital asset disputes should advise on evidentiary sufficiency for your jurisdiction.
What is the right way to document seed phrase storage in the operating agreement?
The OA can describe the process, for example, that seed phrases are split using Shamir Secret Sharing and held by named trustees, without including the phrases, shares, or precise locations. This creates succession-planning clarity without embedding exploitable information. For detailed guidance, see Seed Phrase Storage for Estate Planning and Who Should Know the Seed Phrase in an Estate Plan?.
Does this approach work if a trust owns the LLC?
Yes. When a trust owns a Wyoming LLC holding crypto assets, the trust instrument and the LLC operating agreement each handle their own layer: the trust addresses beneficial ownership and distribution; the OA addresses management authority and custody governance. The wallet inventory schedule sits at the LLC level and is managed by the LLC's manager. Neither the trust instrument nor the OA should contain device serial numbers or private key material.
