Multisig Is a Suicide Pact for Your Inheritance
Your 2-of-3 multisig is elegant security theater — until your grieving spouse needs to coordinate a transaction with your business partner who's on vacation in Bali.
Multisig in Theory vs Practice
In theory, multisig is the gold standard of crypto security. A 2-of-3 setup means no single person can steal your funds. It's distributed, redundant, and mathematically elegant.
In practice, it's a coordination nightmare for people who didn't set it up.
Your heirs must:
- Understand what multisig IS
- Know who holds the other keys
- Contact those key holders
- Coordinate signing a transaction across multiple devices
- Do all of this while grieving, potentially across time zones, with people they may not know
Your spouse is crying at your funeral. Your business partner is in Bali. Your lawyer doesn't know what a "PSBT" is.
That's your inheritance plan?
The Coordination Tax
Every additional signer adds: • Communication overhead • Schedule coordination • Technical skill requirements • Trust dependencies • Points of failure
A 3-of-5 multisig has 10 possible signing combinations. Your heir doesn't know which 3 people to contact, or even that they need exactly 3.
And here's the worst part: multisig setups change over time. You added your college friend as a signer in 2022. You haven't spoken to him since 2024. He moved, changed his phone number, and lost his hardware wallet.
Your elegant security architecture just became a single point of failure.
Simplify the Inheritance Path
Don't force your heirs to learn cryptography.
Instead of handing them a multisig puzzle, hand them a single, clear set of instructions delivered automatically by ZeroLatch:
Option A: The Override Key Store the "master" key (enough keys combined to meet the threshold) in your ZeroLatch vault. Your dead man's switch delivers all the keys your heir needs in one email. No coordination required.
Option B: The Simplification Instruction Include instructions in your ZeroLatch vault for how to convert your multisig holdings to a simple single-sig wallet, with step-by-step screenshots.
Multisig is for protecting assets from threats. It's not for passing assets to heirs. Use the right tool for each job.
