Keep Your Wallet Ultra-Safe by Using Multisig

Multisig, or Multi-signature, is a wallet configuration that needs a minimum of two keys to authorize a transaction. Commonly used by crypto exchanges to make sure that the funds can’t be moved by a rogue, Multisig has applications for the end-users.

If you are looking to enhance the security of your non-custodial bitcoin wallet, then multi-signature may be the answer for you.

Perfect Custody Solution

There’s nothing like a perfect bitcoin wallet. Hardware wallets can be opened under duress. Paper wallets can wither. Mobile wallets can disappear. And, then there are custodial wallets, that are not more than an exchange hack or exit scam away from getting drained.

But, there’s one solution which combines some of the best elements of custodial as well as non-custodial wallets – Multisig Wallet.

A multisig wallet requires a minimum of two key signatures for authorizing a transaction, which means that you will need to trust another party. Different from storing funds on an exchange, though, you have to choose the identity of the 3rd party, and even if that keyholder need to hoodwink you, they won’t be able to access your funds.
