Description
Multisig explained simply: what a multisig wallet is, how 2-of-3 works, the five ways to hold your keys, and when one hardware wallet stops being enough.
One seed phrase, one device and one company's code is a single point of failure. A multisig wallet needs several keys to sign, so a stolen seed, a lost device or a bug in one maker's firmware can't take your bitcoin on its own. In July a Coldcard firmware flaw drained thousands of single-key wallets; most people who held that same device as one key of a multisig lost nothing.
What we cover:
• What multisig is, in plain English: M-of-N, and why 2-of-3 is where most people start
• How multisig works on Bitcoin (built into the address) and on Ethereum (Safe)
• Why you should never use 2-of-2
• Five ways to set up a 2-of-3: all three keys yourself, one with someone you trust, 3-of-5, a phone key, and a company key
• Why we would never recommend handing a company one of your keys
• Use different hardware wallet makers so no single company holds enough keys to sign
• Multisig pros and cons
• The wallet file (descriptor) you must back up
• When you need multisig: would losing this change your life?
