Most people today use single-signature wallets, which means they require only one signature to send funds. These wallets also provide a single seed phrase, which is a list of 12 or 24 words, to use as a backup. Unfortunately, this seed phrase is a single point of failure.
Casa vaults, on the other hand, are multisig wallets. Casa uses five seed phrases, or keys, to create one wallet. The multisig vault also requires multiple signatures from any three of those five keys in order to send funds. Because of this, your security is a lot more flexible, redundant, and safe.
Before we continue, let's prepare to set up your vault by going over the following topics:
- Browser and desktop requirements for Casa
- Seed phrases and the mostly seedless setup
- Basics of digital security hygiene
