Multisig, short for multi-signature, is a security feature in cryptocurrency wallets that requires multiple private keys to authorize transactions.

Multisig is a security measure designed to enhance the safety of cryptocurrency transactions. In traditional cryptocurrency wallets, a single private key is used to sign and authorize transactions. If someone gains access to this key, they can control the funds in the wallet. However, with multisig wallets, multiple private keys are required to initiate a transaction, adding an extra layer of protection.

Typically, a multisig wallet requires a predefined number of signatures out of a total set of signatures to approve a transaction. For example, a 2-of-3 multisig wallet requires two out of three authorized parties to sign off on a transaction before it can be executed. This feature is often used by businesses, organizations, and even individual users who want added security for their funds.


  • A business wallet requiring signatures from three out of five executives to approve a Bitcoin transaction
  • Let's see a real-life example of how multisig works:

A cryptocurrency exchange wants to implement enhanced security measures for its hot wallet, which holds a significant amount of user funds. They set up a 3-of-5 multisig wallet, requiring any three out of the five designated exchange administrators to sign off on outgoing transactions.

Now, if a hacker attempts to compromise the wallet and steal funds, they would need to gain access to at least three of the five private keys, which significantly reduces the likelihood of successful theft. Multisig provides the exchange with an added layer of protection, ensuring that no single individual can initiate transactions independently.
