Setting up a MultiSig wallet

Multisig addresses may be used in different contexts, but most use cases are related to security concerns. Hereby we discuss their use within cryptocurrency wallets. Multi-signature wallets or “multisig wallets” for short, are a type of cryptocurrency wallet for which at least two private keys are needed to sign a transaction. In some cases, it is desirable to have multiple levels of approval for spending cryptocurrencies. As the name suggests, multi-signature wallets require authorisation of transactions through multiple keys, meaning that a group of users is required to sign to approve a transaction. A MultiSig wallet is a digital wallet that operates with multisignature addresses.

A wallet is an application or device that helps you manage your bitcoin, beginning with your private keys. Private keys are used to generate digital signatures, which prove you’re the true owner of your bitcoin and can spend it. Casa’s multisig wallet provides additional redundancy, which protects your bitcoin from attacks. This type of MultiSig wallet requires 2 out of 3 existing private keys to authorize transactions. They are often used by exchanges to enhance the security of their hot wallets. An exchange that supports 2-of-3 MultiSig addresses holds one private key online and keeps the second one offline on an isolated device (sometimes called a “paper” backup).

When a single signer is required, you need to propose and then confirm the transaction. This means that there are N total signers, of which M have to approve and sign before the action occurs. This is called an M/N multisig; the ratio of M to N is called the quorum quotient. For example, a 3/5 multisig would have five signers, three of whom would need to agree to or approve an action. This article focuses on how to make the best design choices when setting up a multisig and how to avoid common mistakes. We’ll walk through demos of several different multisig configurations.
