Multisig wallets are the ultimate level of security for your crypto assets. What are they? Multisig wallets allow you to define multiple addresses with different private keys to validate transactions. It is useful in two different cases. You can use it to share funds with multiple people who can cooperatively control the activity of the wallet. Alternatively, the wallet can require approval from multiple devices owned by the same person with the goal of increasing the level of security.
The individuals or devices using the mulstisig wallet are “co-signers”. A good multisig wallet also allows you to define subsets of co-signers to sign some transactions. In other terms, you can define 2 roles: the owners of the wallet and the validators who validate the transactions. In fact, this leads to a better level of security than regular cold storage wallets. What are the best multisig wallets on the market?
