Casa is a non-custodial self-custody service focused on the secure storage of Bitcoin and stablecoins, founded in 2018. Its website emphasizes that Casa does not hold, control, or transmit customer funds. Its core product combines multisig vaults, a mobile app, hardware wallets, and the Casa Recovery Key to help users hold assets securely over the long term, with inheritance planning and human security advisor support. It is not a traditional exchange; it is closer to a high-security wallet and collaborative self-custody service.
Casa’s main focus is its multisig vaults. A 3-key vault is protected by 3 keys and requires 2 signatures to move funds; a 5-key vault is protected by 5 keys and requires 3 signatures. According to the website, keys can be distributed across mobile devices, hardware devices, and the Casa Recovery Key. Except for the mobile key, keys can be kept in cold storage, and Casa supports key replacement if a device is lost or damaged. This design helps reduce risks such as single points of failure, fire, theft, hardware failure, social engineering attacks, and supply-chain attacks. Casa also states that it meets SOC 2 requirements and uses independent audit controls to verify system security, availability, and integrity.
The site explicitly mentions protection for bitcoin and stablecoins, and refers to ether in its use cases, but it does not provide a complete list of supported assets or trading pairs. The Casa App offers one-tap buying and selling of digital assets, and the website describes the fees as low. It also offers a dedicated OTC trading desk for large Bitcoin positions. However, buy/sell services are provided by Zero Hash LLC and Zero Hash Liquidity Services LLC, while Casa itself is primarily security software. Specific subscription pricing, trading fees, minimums, fiat rails, and payment methods were not disclosed in the captured text.
On the compliance side, Casa Financial, LLC is registered as a FinCEN Money Services Business. Zero Hash LLC holds a New York State DFS virtual currency business license and maintains money transmitter licenses in the required U.S. jurisdictions. Support is one of Casa’s strengths: the website repeatedly highlights one-on-one, white-glove guidance covering setup, recovery, and ongoing protection. This has practical value for long-term holders who do not want to manage all seed phrase and hardware wallet risks entirely on their own.
Casa’s strengths are its relatively complete combination of non-custodial design, multisig, cold storage, inheritance planning, and human support. It is especially suitable for long-term BTC holders, high-net-worth individuals, family inheritance planning, corporate treasuries, and organizational asset management. Its drawbacks are that trading is not the main focus, there is no information on derivatives or leverage, pricing and fee transparency is limited, and buying/selling depends on third parties, which may restrict regional availability.
The captured text does not state whether Casa is accessible from mainland China, or whether KYC or payment methods are available there, so access from China is rated as unknown. Users in mainland China should carefully verify network accessibility, Zero Hash regional restrictions, identity verification requirements, and fiat payment support. Comparable alternatives include hardware wallets such as Ledger and Trezor, multisig/collaborative custody services such as Unchained, and institutional-grade solutions such as Fireblocks and Coinbase Custody.
