3-of-5 multisig vs. 2-of-3 multisig - a comparison

At the Gold level of membership, Casa offers a 2-of-3 multisig key management solution.

2-of-3 multisig offers far more protection than exchange account security, and even more protection than a single hardware wallet device by itself. 

At the Platinum and Diamond levels of membership, Casa offers a 3-of-5 multisig key management solution. 

3-of-5 multisig offers even better protection than 2-of-3.

What are the advantages of choosing a 3-of-5 over a 2-of-3?

With 2-of-3, there are three total keys, with any two key signatures needed to move funds. With 3-of-5, there are five total keys, with any three key signatures needed to move funds. While 2-of-3 is recommended for securing up to $75,000 worth of value, we recommend 3-of-5 for amounts over that, for the following reasons:

  • Additional keys
    • Having more keys means more protection, both from theft as well as user error. In a 3-of-5 setup, up to two keys can be lost, and funds can still be moved. Likewise, up to two keys can be compromised by an attacker, but the attacker would not be able to move your funds. 
    • Keys can be more geographically distributed.
  • Free key replacement
    • Losing and replacing a key can be stressful. If this happens, Casa will send you a free replacement device, and walk you through the setup of your new key.
  • Enhanced Casa Recovery Key verification
    • One key in your setup is held by Casa to be used in emergency scenarios where there is other key loss or theft.
    • In a 3-of-5 setup, verification for recovery signatures is done quickly, via live video verification with a Casa team member.
    • We offer the option to set up custom duress words for video verification.
  • Emergency lockdown
    • Emergency lockdown gives you the ability to disable all login to Casa App.
    • In a 3-of-5 setup, emergency lockdown disables login until video verification with a Casa team member is complete.
  • Bespoke onboarding
    • 3-of-5 clients receive one-on-one, live video calls with our team during the onboarding process
    • Setup calls are personalized to your needs.
