What it is
A multisig wallet is a type of cryptocurrency wallet that requires more than one private key signature to sign and execute a transaction. For example, a "2-of-3" multisig wallet needs any two out of three designated private keys to authorize a spend. This setup adds a layer of security by preventing a single point of failure; if one key is lost or compromised, funds remain secure as long as the other required keys are safe.
Multisig wallets are commonly used for shared organizational treasuries, family funds, or by individuals seeking enhanced security for their own substantial holdings. For instance, a company might use a 3-of-5 multisig setup for its Bitcoin treasury, requiring agreement from multiple executives for any large transaction. This technology is often discussed in the context of self-custody solutions, providing a more robust alternative to single-key wallets.
Why it matters
Multisig offers enhanced security for retail investors by requiring multiple approvals for transactions, protecting against single points of failure like lost or stolen keys.
