A MultiSig Wallet (Multi-Signature Wallet) is a crypto wallet that requires multiple signatures to validate a transaction, so in a transaction sending/transferring crypto to another wallet a multisig wallet requires more than one key or signature to increase the security of crypto stored in the wallet .
Multisig crypto wallets have been in operation since 2013 in various forms/types, so users must be able to decide exactly when setting up private keys, how many private keys are available and how many are needed to validate a transaction. There are several types of multisig wallets that we often encounter, such as two-of-three, two of two, three of four, five of seven, etc. Examples of multisig wallets are Electrum.org, Bitcoinarmory.com, Whalesheaven.com, Coinbase, Ledger Nano X etc.
