What is Bitcoin Multisig Wallet?
A multisig wallet is a secure way to store Bitcoin, allowing multiple parties to sign transactions with their own private keys. It offers increased security compared to single signature wallets and can protect you against online threats like malware, hacks, and phishing attacks.
Why Use Multisig Wallet?
Using a multisig wallet provides an extra layer of security when storing Bitcoin. With two or more private keys required to sign transactions, it becomes more difficult for hackers to gain access to your funds. Additionally, multisig wallets allow you to store your Bitcoin in different locations, such as on hardware devices and in cold storage.
Types of Multisig Wallets
There are two types of multisig wallets: collaborative custody wallets and self-custody wallets. Collaborative custody wallets involve using a third party to manage one of your private keys while self-custody wallets allow users to distribute the private keys themselves. DIY devices are also available for extra security and privacy when creating a self-custody wallet.
Best Collaborative Multisig Wallets
In a collaborative multisig wallet, which is likely to offer 2-out-of-3 key management, users have control over one private key while the third party holds the second key online and the third offline in cold storage. This provides convenience but comes at the expense of privacy due to possible KYC procedures that may be required by companies providing these services. Furthermore, these services may not be available globally due to geographical limitations. Some popular collaborative multisig wallets include Casa and BitGo.
Best Self Custody Wallets
Self-custody wallets provide users with complete control over their private keys without having any reliance on third parties or companies providing customer service support if anything goes wrong. These solutions are ideal for those who want low cost and privacy as they can buy their own components and build their own device that leaves no trace other than securely generating private keys. Some popular options include Ledger Nano S/X , Trezor Model T/One , KeepKey , Coldcard , OpenDime .
