1. Setting up your Casa Key Shield


Getting started

Most people today use single-signature bitcoin wallets, which means they require only one signature to send bitcoin out of that wallet. 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.
The Casa Key Shield on the other hand is a multisig wallet. Casa uses five seed phrases, or keys, to create one bitcoin wallet. The multisig wallet also requires multiple signatures from any three out of those five keys in order to send bitcoin. Because of this, your bitcoin security is a lot more flexible, redundant, and safe. 
Before we continue, let's prepare for your multisig setup by going over the following topics:
  1. Browser and desktop prerequisites for Casa
  2. Seed phrases and the mostly seedless setup
  3. Basics of digital security hygiene
  4. Setup checklist
