# Multi-signature wallet (multisig)

A multisig wallet is a crypto wallet that requires more than one private key to approve a transaction. In other words, a multi signature wallet enforces an M-of-N rule (for example, 2-of-3), so no single person or device can move funds alone. If you’re asking “what is a multisig wallet” in practice, it’s a setup that distributes control and reduces single-key risk for teams, treasuries, and long-term storage.

The multisig wallet meaning is on-chain policy: the blockchain itself checks that the required number of signatures is present before funds can be spent. A multi signature crypto wallet can be fully self-custodial (each signer holds their own key) or run by a custodial provider that coordinates co-signing with role-based approvals.

## How it works

1. Define participants and a threshold. You choose the owners (N) and how many signatures are needed (M). Common choices are 2-of-3 for small teams and 3-of-5 for larger treasuries.
2. Create the wallet.
   - On Bitcoin and similar UTXO chains, a multisig address is derived from the set of public keys and the threshold (e.g., P2WSH/P2SH).
   - On account-based chains (e.g., Ethereum), a smart-contract wallet (such as a “Safe” wallet) enforces owners and the threshold.
3. Propose and co-sign. One owner drafts a transaction. Other owners review and add signatures from their devices.
4. Broadcast and confirm. Once M signatures are attached, the transaction is broadcast to the network and confirmed on-chain.
5. Maintenance and recovery. Most implementations let you rotate keys or update owners via a governed transaction, so the group can replace a lost or compromised key without losing access.

**Note:** multisig differs from MPC (multi-party computation). MPC splits one key across devices and produces a single signature; multisig records multiple signatures or enforces a threshold in a contract. Both aim to reduce single-key risk, but they’re implemented differently.

## Key benefits

- Shared control. Separates duties so no single actor can unilaterally move funds – useful for boards, DAOs, and finance teams.
- Reduced single-point risk. A stolen or lost key alone cannot drain the wallet; the threshold still protects funds.
- Continuity. With setups like 2-of-3, the group can operate if one device fails, while still requiring multiple approvals.
- On-chain policy and auditability. The threshold is enforced by the chain or contract, creating a clear approval trail.
- Flexible governance. Contract-based multisig can add features like spending limits, time locks, or module-based approvals.

Multisig is commonly used for treasury management, exchange cold storage, OTC escrow, grant programs, and any workflow where predictable approvals matter.
