what's Casa?

Casa is a Bitcoin-focused security company that provides self-custody solutions for digital assets. It offers multisignature wallet services, allowing users to secure their Bitcoin and Ethereum using a combination of mobile apps, hardware devices, and recovery tools. The platform emphasizes user sovereignty, with features like key management, subaccounts for separating funds, and integration with Lightning Network for faster transactions. Casa's approach avoids holding user keys, instead guiding users through best practices for personal control. In addition to core wallet functionality, Casa introduces specialized tools such as inheritance planning protocols to ensure assets can be passed on securely after the owner's passing. This includes time-locked recovery mechanisms and trusted contact systems. The company also provides educational resources and premium memberships for advanced users, partnering with hardware providers to enhance overall security without compromising privacy.
