We’re excited to partner with Efani, a premium mobile security provider, to help Casa clients safeguard one of the most vulnerable parts of their digital lives—their phone number.
SIM swaps are one of the most common ways attackers compromise crypto users. While holding your own keys is foundational to security, the phone number tied to your accounts can still be a point of failure. Efani eliminates this risk with military-grade protections, rigorous identity verification, and an unmatched track record.
If you’re based in the U.S. and value your privacy, Efani offers a secure mobile experience with concierge onboarding and insurance coverage. As a Casa client, you’ll receive $99 off your plan—either your first month free or $99 off a yearly subscription.
