Crypto and Estate Planning
A guide to generational digital wealth.

A defensible estate plan begins with an accurate ledger of what exists. For digital assets this is more nuanced than a brokerage statement: holdings can sit across self-custody wallets, exchange accounts, staking contracts, multi-sig vaults, and tokenized real-world assets.

• • Catalog every wallet by chain, address, custody type, and approximate value.
• • Document exchange and custodian accounts, including 2FA recovery methods.
• • Note staked, locked, vested, or LP-deployed positions and unlock schedules.
• • Track NFTs, tokenized real estate, and any DAO governance positions.

The inventory itself is sensitive — it should never live in a will, which becomes a public record at probate. Instead it belongs in a sealed letter of instruction referenced by, but separate from, the controlling estate documents.

The defining problem in crypto estate planning is the irreversible loss that follows a lost seed phrase. A succession plan must guarantee that the right heirs — and only the right heirs — can reconstitute access at the right moment.

Threshold custody

Multi-signature wallets (Gnosis Safe, Casa, Unchained) and Shamir Secret Sharing schemes let you split signing authority across multiple parties: a family principal, a trustee, and an institutional co-signer is a common 2-of-3 design. No single key — including yours — can move funds unilaterally, and no single loss is fatal.

Dead-man's switch architecture

Time-locked release mechanisms (e.g., Sarcophagus, Safe modules, or custodian inheritance products) can hand control to a named beneficiary if you fail to check in over a defined interval. These must be paired with legal documentation so the onchain transfer maps cleanly to the offchain estate.

Hardware and material storage

Seed phrases belong on steel — not paper, not cloud, not a password manager. Distribute shards across geographically separate safe-deposit boxes or institutional vaults, with access keyed to the trustee structure described below.

A trust is the right wrapper for nearly all material crypto holdings. It avoids probate, preserves privacy, and lets you encode rules — distribution ages, spendthrift protections, charitable remainders — that a raw wallet cannot.

Revocable living trusts

The everyday workhorse. Title custodial accounts and wallets to the trust during life so they pass to beneficiaries without court involvement. Pair with a pour-over will to capture any assets accidentally left outside the trust.

Irrevocable and dynasty trusts

For families with significant onchain wealth, an irrevocable trust — often a dynasty trust sited in a jurisdiction with no rule against perpetuities (South Dakota, Nevada, Delaware) — removes future appreciation from the taxable estate and protects assets from creditors across generations.

Directed trustees and key holders

Traditional corporate trustees rarely custody crypto directly. A directed-trust structure separates fiduciary duties from technical custody: the institutional trustee administers the trust while a qualified custodian or family office holds the keys under written investment direction.

Crypto's volatility makes it uniquely suited to estate-tax planning techniques originally designed for concentrated growth stock. Used correctly, these structures move appreciation out of the taxable estate while preserving family access.

• Step-up in basis. Under current U.S. law, digital assets held at death receive a basis adjustment to fair market value — often the single largest tax benefit available to long-term holders.
• Grantor Retained Annuity Trusts (GRATs). Ideal for volatile assets: outsized appreciation passes to heirs free of gift tax if the underlying holdings outperform the IRS hurdle rate.
• Intentionally Defective Grantor Trusts (IDGTs). Combine the income-tax treatment of a grantor trust with the estate-tax treatment of an irrevocable trust, letting you "burn down" the estate while compounding occurs outside it.
• Charitable Remainder Trusts (CRTs). Convert a concentrated, low-basis position into a diversified income stream with a current charitable deduction and deferred capital gains.
• Annual exclusion and lifetime exemption gifting. Transfer fractional wallet interests through an LLC to use exclusions efficiently and lock in current valuations.

None of these is a do-it-yourself exercise. Each has filing requirements, valuation discipline, and ongoing administration that must be coordinated with counsel and a CPA fluent in digital assets.

The most elegant estate plan fails if heirs cannot operate it. Generational transfer of digital wealth is as much an education problem as a legal one.

• • Run annual "fire drills" with trustees and successor key holders.
• • Maintain a living memorandum that explains the why behind each structure.
• • Train beneficiaries on operational security before they inherit control.
• • Codify a family investment policy statement covering digital allocation.
