From a security standpoint, it is critical that cryptocurrencies be stored in a manner that avoids the risk associated with a single point of failure, that is, a single vulnerable point that can compromise the whole wallet.
Requiring just one private key to sign a transaction is one such vulnerable point. To address this issue, it is advisable to use a wallet that requires more than one private key for transaction authorization. In such special wallets, two, three, or even more private keys are required from various sources.
Many blockchains support the creation of multi-signature addresses, and many wallet providers and exchanges use some kind of multi-signature wallet to protect their clients’ assets.

What is a MultiSig Wallet?
Multisig wallets are a kind of crypto wallet that demands the use of two or more private keys to authorise transactions.
In layman’s terms, consider it a safe with distinct keys that must be used in tandem to open it. This is done to enhance the security of the funds kept in the wallet by requiring several parties to sign on any transaction before sending it.

How Do MultiSig Wallets Work?
A multisig wallet works by requiring several signatures from a set of predetermined addresses, and if any of these signatures is missing, the transaction will fail.
Multisig wallets are smart contract-based wallets, as they are controlled by code and governed on-chain by their owners. Due to this, multisig wallets are regarded as a “seedless” type of self-custody.
Although there are various kinds of multisig wallets, the two most common are:
1) The first kind necessitates that all parties sign a transaction.
2) The second kind needs a specific number of participants from the overall pool to sign for a transaction to be processed, such as two of three or three of five.
This implies that even if one of the keys is compromised, your assets will still be protected.
