What Is a Multisig?

A multisig, multi-signature wallet, requires more than one key to approve a transaction: 2-of-3, 3-of-5, or any threshold you configure. No single key can move the money, so no single mistake, theft, or rogue insider can either. It is how serious treasuries hold crypto, and it is available to careful individuals too.

How It Actually Works

A smart contract (Safe, formerly Gnosis Safe, is the standard on EVM chains) or native protocol feature holds the funds and enforces the threshold.
Keys live in different places: separate hardware devices, separate people, separate locations. A 2-of-3 might be your hardware wallet, a second device in a safe, and a trusted party's key.
Any spend needs the threshold count of signatures before the contract executes it. Losing one key is survivable; compromising one key achieves nothing.

Who Uses It

Project treasuries and DAOs, where one person holding the keys is the historical prelude to headlines.
Businesses that need two-person control the way bank accounts have dual signers.
Individuals with meaningful holdings who want theft of any single device or location to be a non-event, including estate planning where a family member holds one key.

Risks and Common Mistakes

Complexity is its own risk. More keys, more backups, more places to make an untested mistake. Practice recovery before funding seriously.
Correlated storage defeats the point. Three keys in the same house is one house fire away from zero-of-three.
Signer diligence still matters. A multisig approving a hostile contract interaction loses funds with full ceremony. Simulation tools and the habits from token approvals apply to every signer.

When It Matters

Shared funds, large personal holdings, and any situation where "one key, one point of failure" keeps you up at night. For most individuals a hardware wallet plus tested backups comes first; multisig is the graduation. Setup guidance is the kind of session I do: About.
