What is Casa?
Casa is a self-custodial wallet platform built around multi-key vault architecture for long-term holders and organizations. By dividing signing authority across multiple hardware devices, a mobile phone, and an emergency recovery key held by Casa, the platform prevents single points of failure like seed-phrase theft or hardware damage.
Founding and background
Casa was founded in 2018 and is based in Denver, Colorado. Original founder Jeremy Welch launched the company before later taking an executive role at Kraken. CEO Nick Neuman, formerly Head of Product, leads the business alongside Co-Founder and CTO Jameson Lopp, a veteran cypherpunk and former BitGo engineer. Casa raised a $2.1 million seed round in 2018 backed by Boost VC, Lerer Hippeau, and Compound, followed by a Series A round with Stillmark.
How multi-key custody works
Casa operates on threshold multi-signature security for Bitcoin and smart contract multi-key architecture for Ethereum and USDC. In a 3-key setup, moving funds requires two signatures: typically one from a mobile device and one from a supported hardware wallet, such as Ledger or Coldcard. Casa holds an optional third recovery key to co-sign if a primary device is lost, but Casa cannot move funds independently. Premium configurations scale to 5-key vaults requiring three signatures, distributing keys across hardware wallets placed in distinct geographical locations. Users do not manage single seed phrases on paper, reducing exposure to phishing and physical extraction attacks.
Membership pricing and availability
The platform runs on an annual subscription model rather than per-transaction custody fees. The Standard plan costs $250 per year for a 3-key vault, built-in inheritance planning, and mobile signing. The Premium tier costs $2,100 per year, adding a 5-key vault, shipped hardware packages, and video verification. Private Client tiers cost $7,500 per year for custom 5-key or 6-key configurations and a dedicated advisor. Casa apps are available globally across more than 46 countries on iOS and Android. Setting up a vault requires no identity verification documents, but buying or selling bitcoin through in-app broker integrations relies on regional partner KYC.
Risks and considerations
Because Casa focuses squarely on cold storage, it lacks built-in decentralized application browsers and token swaps. Sovereign recovery requires retaining offline setup files in case Casa ceases operations. In addition, subscription renewals must be maintained to access Casa's co-signing server and inheritance execution services.

Pros and cons
Pros
- Eliminates single seed-phrase points of failure through threshold multi-device signing
- Casa cannot move user funds unilaterally because it holds at most one key
- Hardware wallet diversity prevents single-vendor firmware supply chain compromises
- Integrated inheritance setup allows heirs to recover assets without seed technicalities
Cons
- Requires ongoing paid subscriptions starting at $250 per year
- Supports only Bitcoin, Ethereum, and stablecoins rather than broad crypto ecosystems
- Lacks in-app decentralized finance tools, cross-chain swaps, and dApp browsing
- Recovery using Casa's co-signing key depends on active platform account status

Casa offers resilient multi-key self-custody and inheritance planning for Bitcoin and Ethereum, but requires ongoing subscription fees and supports very few blockchains.
Casa focuses on self-custodial multi-key security designed to eliminate single points of failure. Rather than relying on a single seed phrase or hardware signer, Casa distributes signing keys across multiple devices and environments. Its primary configurations use 2-of-3 or 3-of-5 threshold multisig setups where Casa holds only one co-signing key for emergency recovery. Because the company never controls a threshold quorum, users retain full self-custodial ownership of their assets.
Supported assets are intentionally restricted. The platform handles Bitcoin, Ethereum, and stablecoins like USDC, leaving out altcoins and general smart-contract ecosystems. Interaction occurs via mobile applications on iOS and Android, pairing directly with third-party hardware signers like Ledger and Coldcard. This multi-vendor approach safeguards funds against single-manufacturer supply-chain vulnerabilities, letting clients construct vaults using independent hardware brands.
The service model relies on annual subscriptions rather than free access. Pricing tiers include Standard at $250 per year for 3-key setups, Premium at $2,100 per year for 5-key architectures with included hardware packages, and Private Client at $7,500 per year with dedicated advisory support. A key differentiator is Casa Inheritance, an integrated protocol that coordinates vault access for beneficiaries without requiring technical estate setups or giving Casa asset control.
Casa suits long-term Bitcoin and Ethereum holders seeking institutional-grade resilience against hardware loss or physical coercion. Users seeking broad multi-chain support or free software wallets should look elsewhere.

In their own words
“Proper Bitcoin self-custody Casa is built for people who actually hold Bitcoin. True non-custodial multisig so no single key, phone, or company can move your coins. Hardware keys stay in your control, they only hold a recovery key that is useless by itself.”
“Self custody I love this service I feel like they held my head and walked me through the self custody process, took all the fear out of it”
“Great app Very easy and secure way to secure your bitcoin. We definitely recommend it. Customer support has been great and the price is reasonable.”
“No privacy Doesn’t work unless you give it your personal information like your email. So much for crypto privacy.”
“Can’t buy Bitcoin from the app no more The UI is great but it’s super expensive to use just a custodial wallet without the option of buying bitcoin within the app. I know it used to be why was it yanked off?”
“Not recommended can’t set up wallets No happy with this app, they charge me the whole subscription even if you can make it work or not,I got problems with my nano ledger S I can’t set it up,I cancel my subscription and now they said they cannot give me a refund,they just cancel the subscription…”

As attackers get more sophisticated, multi-vendor multisig reduces single points of failure and human error while leaving the keys with you.
Secure sovereignty comes from setups that assume things will go wrong, include a plan, and still leave you in control.

We are an official Ledger reseller and source the Ledgers that we provide to our clients directly from Ledger.
They are then stored in an access controlled location until being sent to Casa clients with the original Ledger packaging intact.
The Ledger supply chain incident is another reason why we designed Casa to integrate with many different hardware signers and vendors - to protect against vulnerabilities from any one device.
