Written By : Samradni

Cryptocurrency is a smart way for many investors to invest their hard-earned money. With the evolution of the cryptocurrency sector, users are getting safer solutions to manage transactions. A multi-signature wallet is a cryptocurrency wallet containing many security features. This wallet authorizes cryptocurrency transactions and saves funds earned from the transactions.

If one is wondering what a multi-signature wallet is and how it works, this guide is for them. It also highlights the different types of multi-sig wallets and their benefits.

How do multi-sig wallets work?

Many cryptocurrency users want to know what a multi-sig wallet is and how it works. These wallets need 2 or more than 2 private keys to carry out a cryptocurrency transaction. The wallet owners must sign a smart contract to use a multi-signature wallet and agree to the rules to access it.

Multi-sign wallets act as self-custody, allowing owners to access the transactions safely. These smart wallets work better than traditional wallets, which lack many safety features.

Kinds of Multi-signature wallets

Before using a multi-sig wallet, users must understand the different kinds of wallets. Here is the list of the different types of multi-signature wallets:

1-of-2 signatures

Two users who know each other can share the funds using one of two signatures. This kind of multi-sig wallet does not require authorization.

2-of-3 signatures

2-of-3 signatures is one of the best multi-sig wallets with two private keys. These wallets will transact after the user provides two private keys. The user will have one key online, one offline key, and the third one with a security company.

3-of-5 signatures

In this wallet, the users will store 4 keys in various offline locations. The fifth key will be available with the security company for safety purposes. The key holders can access this wallet with the help of 2 or 4 offline keys.

Benefits of using multi-signature wallets

Most cryptocurrency holders are now choosing multi-signature wallets to execute safe transactions. These wallets provide many benefits, such as:

1. Difficulty for hackers

Online transactions always involve a high risk of fraud and hacking. Multi-signature wallets enhance crypto wallet security and make it difficult for hackers to steal information. The passwords are saved in multiple locations and devices, making hacking impossible for third parties.

2. Possible to edit the contract

One of the major benefits of using multi-signature wallets is the ability to change the smart contract. The wallet users can easily make changes to the contract anytime as required.

3. Useful tool for co-signers

Co-signers can use a multi-sig wallet even in the absence of one party. They can enter the key and conduct a transaction from anywhere.

Conclusion

The increase in the use of multi-signature wallets will decrease the number of fraudulent activities in the crypto sector. Users must know how to use a multi-signature wallet and how it works to enjoy safe transactions. The wallets give crypto holders full control to keep their assets secure.
