Hardware wallets are safer than leaving your coins on an exchange, but they’re also single points of failure.
‍
Consider: What happens if you lose your hardware wallet or it gets damaged? What if you forget the PIN? Or accidentally wipe it with a firmware update? Seed phrase backups mitigate these risks, but they are also points of failure. Many hardware wallets can be hacked by sophisticated thieves. Also, leaving your coins on a single hardware wallet at a single location leaves you vulnerable to threats like robbery or natural disaster.
‍
We built Casa to protect Bitcoiners from these dangers. Your Bitcoin is protected by multiple devices (typically: your phone + 1 hardware wallet), which means that if you lose  your phone, or if your hardware wallet is stolen, your coins will still be completely safe and Casa is on standby 24/7 to get back to full security ASAP. This resilient design allows you to stay in full control of your coins and protects you from a laundry list of physical and digital hazards.

Casa Gold is $120 per year, or $10 per month.

For Gold memberships, you’ll need at least 1 hardware wallet to get started. Casa works great with:

You can cancel anytime from your account or by emailing us at [email protected]. Three days before your trial ends, we’ll even email you a reminder in case you want to cancel before you’re billed.

Casa uses multisig security. “Multisig” is short for multi-signature, and it means that spending funds requires more than one approval or “sign-off.” Casa is not reinventing the wheel when it comes to multisig technology. We use battle-tested, open-source, pay-to-script-hash multisig technology that has been live on Bitcoin for 8 years, and today is protecting nearly 6 million Bitcoin ($50 billion). We do NOT use Shamir’s Secret Sharing, experimental cryptographic techniques, or other off-chain multisig schemes.

Casa Gold is built to secure $1,000 - $50,000 worth of Bitcoin. If you’re securing more than that, we recommend our Platinum or Diamond memberships. Many Casa members start out using Gold, and then upgrade to Platinum or Diamond later on.

Casa can never access your funds - even if we wanted to. With multisig, multiple keys are required to spend your Bitcoin, and Casa only ever has access to 1 key (for use in emergencies only). This also means that it’s impossible for Casa to ever stop you from accessing your Bitcoin. And that even if Casa were under attack, your funds would still be 100% safe from thieves or hackers. It’s all part of our strict ‘Can’t Be Evil’ design.
