Planning how to leave cryptocurrency to heirs requires both technical steps and legal thinking. Cryptocurrency is non-custodial by design: whoever controls the private keys controls the assets. Think of your seed phrase like the master key to a safe deposit box. Lose the key, and access can be gone forever.
I believe that a clear plan reduces stress for heirs and preserves value. In my experience, the single biggest failure I see is good intentions paired with poor documentation (and no test). This guide focuses on practical, device-focused strategies — including trezor inheritance and how to leave crypto to heirs — while pointing to deeper technical material.
Keep this inventory current. Who should know it? Someone trusted and ideally tech-capable (a friend, family member, or a digital-assets attorney).
Making these early is vital. Do you want a simple handoff (single-signature) or a more resilient approach (multisig)? Will you use a passphrase (25th word) to add plausible deniability? Each choice has security and inheritance trade-offs.
Wondering which to pick? Consider how many trusted parties you can involve and their technical skill.
| Strategy | How it works | Pros | Cons | Best for |
|---|---|---|---|---|
| Single-sig (hardware wallet + metal backup) | One device + seed phrase on metal plate | Simple, low tech for heirs | Single failure point; wills can leak info during probate | Small estates; tech-savvy heir |
| Single-sig + passphrase (25th word) | Seed phrase + secret passphrase required to access funds | Extra security, plausible deniability | Heir must know passphrase; storing it reduces security | High-risk profiles who can securely passphrase-escrow |
| Multisig (multisig across devices) | Multiple keys held by different parties/locations | No single point of failure; flexible access policies | Setup and recovery are more complex | Larger estates; families wanting distributed control |
| Shamir/SLIP-39 shares + metal plates | Split recovery into shares held by people/places | Can reconstruct without single party having full seed | Compatibility and long-term custody of shares can be tricky | Executors with legal/technical support |
| Custodial/trust service | Third-party holds private keys under legal contract | Easier legal handoff (familiar process) | Counterparty risk; not self-custody | Heirs who prefer traditional probate processes |

Passphrase inheritance is often asked about. The passphrase (25th word) creates an additional, hidden wallet that is not stored on the device or anywhere else. That is both its strength and its weakness.
So what should you do? Options include keeping the passphrase in a legal escrow or splitting it into pieces using SLIP-39 shares. But be careful: placing the passphrase into a will is risky because wills can become public during probate. But don't put the passphrase directly into a will. Consider a trust or a sealed escrow with instructions to reveal the passphrase only under specific conditions.
This section focuses on using a hardware wallet made by the brand central to this site. The steps are practical and device-agnostic where possible. For model-specific setup see trezor-unboxing-and-setup and model comparisons: trezor-model-comparison.
Step-by-step checklist:
And yes, that means rehearsing the same steps with whoever will actually execute the plan.
But consider privacy: minimizing how much information appears in legal records helps reduce theft risk.
Q: Can I recover my crypto if the device breaks? A: Yes, if you have the seed phrase (recovery phrase) properly backed up. Test recovery on a spare device and follow recovering-a-trezor.
Q: What happens if the company goes bankrupt? A: Non-custodial crypto depends on your keys, not the company. As long as you have the seed phrase and compatible firmware/software, you can recover funds. Still, record firmware and compatibility notes for heirs.
Q: Is Bluetooth safe for a hardware wallet? A: Bluetooth adds convenience but introduces attack surfaces. Prefer USB or air-gapped workflows for large holdings. See connectivity-usb-bluetooth-nfc and air-gapped-signing-psbt for alternatives.
Q: How do I avoid probate exposing my seed location? A: Use a trust or sealed escrow. Keep explicit secrets out of probate documents.
Best for: Crypto holders who want self-custody with a clear handoff plan, those using a hardware wallet and willing to document and test recovery paths.
Not ideal for: People who prefer a purely hands-off, custodial approach or heirs who cannot securely store physical backups. In those cases, consider traditional custodial accounts combined with legal estate planning (talk to a lawyer).
Inheritance planning for crypto is a mix of tech and legal work. Start with an inventory, choose a backup strategy that matches your heirs’ skills, and test recovery steps until they’re foolproof. In my testing, a simple rehearsal saved an estate from confusion later.
Next steps: read the basics on seed phrase basics, learn about passphrase (25th word), and consider physical backups (metal-backups-plates). If multisig sounds right, explore trezor-multisig-guide.
And remember: plan early, write clearly, and test often. But don’t put the seed phrase in your will.
