Plain English
Multi-sig means a wallet that requires multiple signatures (private keys) to approve any transaction. A common setup: 2-of-3, where any two of three keys must sign.
How it actually works
Multi-sig is implemented as a smart contract (on chains that support it) or as a native protocol feature (Bitcoin). The wallet’s address is the multi-sig contract; sending crypto from it requires the threshold number of signers to each sign the transaction. Keys can be held by different people, on different devices, in different physical locations.
What it means for you
For positions large enough that a single hardware wallet is a single point of failure, multi-sig is the working solution. It distributes risk across multiple keys, locations, or even people — making it dramatically harder for any one compromise to drain the wallet.
Our curriculum walks through 2-of-3 setups for individuals, family-office structures with multiple human signers, and the operational protocols that keep multi-sig workable in practice.
