We’ve all heard the stories of developers and companies who built great software, only to lose user funds due to poor key management. Our API allows you to connect your users’ bitcoin while they maintain control of their keys.
Say goodbye to triple-checking receive addresses. Our Deposit to Casa feature provides your users with the ability to click one simple button to send bitcoin to their Casa wallets.
Bitcoiners don’t trust — they verify. Our View Balance feature allows you to provide your end users with secure visibility into their Bitcoin wallet balance, so users can be their own bank wherever they go.
If your client has bitcoin, you no longer have to take their word for it. With Casa’s Bitcoin wallet API, you can connect a Casa wallet to your dashboard and share visibility with traditional institutions, lenders, and financial advisors.
The Casa API is currently in closed beta as we onboard partners and add more features. Sign up for our integration waitlist.
When a user holds bitcoin with Casa, their private keys are held in secure cold storage, and no one can spend bitcoin from their wallet without those private keys. Keys generate Bitcoin addresses, for which unspent transaction outputs (UTXOs) are publicly stored on the blockchain.
Similar to a Bitcoin node, the Casa API processes calls for this data without ever revealing private keys.
