Losing access to crypto when someone dies is a billion-dollar problem. Traditional wills don't cover seed phrases. Here are the best hardware wallets and multisig setups for passing crypto to your heirs — from Ledger and Trezor to Keystone and Tangem.
An estimated 20% of all Bitcoin — worth hundreds of billions — is locked in wallets whose owners have died, lost their keys, or gone silent.1 If you hold crypto, the question isn't if your family will need access. It's when — and whether they'll be able to get it.
A traditional will doesn't cut it. Wills are public records. If you write your seed phrase into a will, anyone who reads it can drain the wallet before probate even starts.1 You need a crypto-native plan.
After researching expert guides from Ledger Academy, ChainScore Labs, and FinanceFeeds, three strategies emerge as the gold standard for passing crypto to heirs.1
The simplest approach: store your seed phrase securely and leave instructions for your heirs. But "simple" doesn't mean easy. A single seed phrase is a single point of failure — lose it, and the crypto is gone. Someone finds it, and the crypto is stolen.1
Best for: Small portfolios where the complexity of multisig isn't justified.
Multisignature wallets require 2 or more private keys to authorize a transaction. A common setup is 2-of-3: you hold two keys, a trusted family member holds one, and a lawyer or service holds the third. If you die, your heir combines their key with the lawyer's key to access the funds — without ever seeing your personal seed phrase.1
Services like Casa and Unchained offer managed multisig vaults specifically designed for inheritance.1 Nunchuk and Safe (formerly Gnosis Safe) provide self-custodied multisig options.3
Best for: Serious portfolios where redundancy and security matter more than convenience.
Social recovery wallets let you designate a set of "guardians" — friends, family, or institutions — who can collectively help you recover access. Unlike multisig, the guardians don't hold keys; they hold encrypted shards that can be combined to reset access.2
The trade-off: social recovery is more user-friendly but introduces trust assumptions. If a majority of your guardians collude or get compromised, your wallet is at risk.2
Best for: Users who value convenience and have a trusted network.
| Feature | Single-Sig | Multisig | Social Recovery |
|---|---|---|---|
| Keys needed to recover | 1 | 2+ (threshold) | Majority of guardians |
| Risk of loss | High (single point of failure) | Low (redundant keys) | Medium (guardian dependency) |
| Complexity | Low | High | Medium |
| Best for | Small amounts | Serious holdings | Everyday use |
We selected hardware wallets that integrate well with multisig and inheritance services, or simplify key storage for non-technical heirs.
Ledger is the most widely supported hardware wallet in the multisig ecosystem. It works with Casa, Unchained, Nunchuk, and Sparrow Wallet for multisig setups.1 The Stax model adds a large E Ink touchscreen that displays transaction details clearly — helpful when you're teaching a family member how to verify a transaction.
Why it's #1: Ledger's ecosystem is the deepest. If you want a multisig inheritance plan with professional support (Casa, Unchained), Ledger is the hardware anchor they support out of the box.1
Trezor's firmware is fully open-source, which matters for long-term inheritance planning — you want to know the device your heirs open in 20 years won't be locked by proprietary software. The Safe 5 supports multisig via Electrum, Sparrow, and Nunchuk.3
Why it's #2: Open-source means verifiable security. If you're building a plan that spans decades, Trezor's transparency is a real advantage.
Keystone is air-gapped — it never connects to a computer or phone via cable. Transactions are signed via QR codes. This dramatically reduces the attack surface, making it ideal for a "cold vault" that sits untouched for years until an heir needs it.1
Why it's #3: Air-gap is the gold standard for long-term storage. Keystone also integrates with Casa and Unchained for multisig inheritance setups.
Tangem is a credit-card-sized hardware wallet with no battery, no screen, and no cables. You tap it against an NFC phone. The seed phrase is generated on the chip and never exposed — even to you.1
Why it's #4: If your heirs aren't crypto-savvy, handing them a Tangem card they can tap with their phone is far simpler than explaining seed phrases and multisig. The trade-off: no multisig support, so it's single-signature only.
A "Letter of Instruction" tells your heirs what to do with your crypto — without revealing your seed phrase. Here's the template recommended by Ledger Academy:1
Never put your seed phrase in the letter. The letter is a map, not the keys.1
The best crypto inheritance plan uses multisig with a hardware wallet as the physical key. Ledger Stax gives you the widest ecosystem. Trezor Safe 5 gives you open-source longevity. Keystone gives you air-gapped security. And Tangem gives you simplicity for non-technical heirs.
Whichever you choose: make a plan, write the letter, test the recovery process with a small amount, and update your setup as the ecosystem evolves. Your heirs will thank you.
