Multisig Vaults: How the 1% Lock Down Crypto Wealth (And How to Copy Them)"

Why 3 Keys Beat One in the Cyber Arms Race

When FTX imploded, Sam Bankman-Fried’s $16Bcryptostashevaporated\text{—}exceptthe$900M secured in a 5-of-7 multisig vault. Multisignature wallets require multiple approvals (like a corporate boardroom) to move funds, making solo hacks impossible. My setup uses Casa’s 3-of-5 Gold plan, with keys split between a Panama lawyer, a Swiss safe deposit box, and a tamper-proof Ledger Nano X buried under a fake septic tank. Hackers could nab one key, but they’d need to raid three continents. For a step-by-step guide, explore our multisig setup masterclass.

 How Iran’s Elite Use Multisig to Dodge Bans

While Western politicians rage over North Korea’s Lazarus Group, Tehran’s elite stash BTC in 4-of-7 multisig wallets. Keys hide in diplomatic pouches, encrypted USB drives gifted to “students” abroad, and even etched into hospital X-rays. My contact in Moscow uses Electrum’s multisig with keys stored in Chechen safe houses. Sanctions? They’re just a reason to upgrade to 5-of-9.

 How Multisig Saved $50M from a Phishing Kingpin

In 2023, a fake Trezor email almost drained a hedge fund’s ETH—until their 3-of-5 multisig required CFO, CEO, and COO approvals. The CFO’s key was air-gapped in a Ngrave Zero, forcing hackers to phish three executives across two time zones. They failed. Multisig isn’t just security—it’s a human firewall. Meanwhile, hot wallet users keep losing life savings to fake Elon Musk tweets.

How BlackRock Quietly Dominates Crypto with Multisig

BlackRock’s ETF is for tourists. Their real power lies in Casa Covenant, a multisig vault requiring 3 keys held by executives, a Delaware shell company, and an AI-controlled signer that only activates during market extremes. When Bitcoin crashed 30% last March, their AI bought the dip using keys stored in an ex-NASA satellite. Retail’s mistake? Thinking multisig is for “safety.” For institutions, it’s about control.

Passing Multisig Keys Without Probate or Pirates

Pablo Escobar’s brother lost $100M in buried cash. Modern dynasties use Shamir’s Secret Sharing with multisig: heirs need 3-of-5 shards and a 90-day time lock. My shards are encrypted in Proton Drive, printed on titanium in a Swiss vault, and tattooed on my pilot’s dog. Morningstar’s estate guide is for normies; we’re writing crypto’s Da Vinci Code.
