Introducing Casa Business: Unlocking self-custody for every company

A major theme of 2025 is the continued rise of the bitcoin treasury. One by one, businesses are choosing to adopt bitcoin, whether as a primary reserve asset or a simple hedge.

Many considerations go into that strategy, and it’s easy to overlook long-term threats that can undermine the longevity of your holdings like custodial risk. Today, Casa is making self-custody possible and purpose-built for businesses of any size with Casa Business.

The unspoken custodial risk of bitcoin treasuries

One aspect of building a successful business is reducing your reliance on any one thing, such as a piece of equipment, an investment, or even a person. In security, we call this concept a single point of failure and we work hard to eliminate them as they arise.

It’s crucial for a business to maintain that mindset as it works to preserve capital in the form of bitcoin. There is no going back if it’s too late. In 2019, QuadrigaCX, the largest crypto exchange in Canada at one time, lost $190 million in assets when its CEO and founder died suddenly. The missing assets remain a mystery to this day.

Behind the scenes, we’ve encountered several instances of businesses and business owners who have lost keys. These cases do not always make headlines due to the nature of private companies and the embarrassment for those involved. Additionally, businesses who outsource their custody to third parties can find their assets entangled in unraveling systemic collapse like the FTX bankruptcy through no fault of their own. 

A business needs to act in the fiduciary interest of its shareholders, and in our view, that includes the consideration of single points of failure and third-party custodial risk.

What is Casa Business?  

Through Casa Business, a company can hold some or all of its business treasury in self-custody in a 3-key vault. Assets you can secure include BTC, USDC, USDT, and ETH.

Imagine you’re the owner of a boutique trading firm, and you’re wishing to hold bitcoin and stablecoins in your reserve. You want your assets to be protected, but you still need the ability to access it relatively easily for your everyday operations. And while significant, the holdings you’re securing are not yet large enough to justify the additional protection of a 5-key vault.

Casa Business is a good fit. This new option provides a framework for beginning your treasury and holding it for the long term, whether you’re a startup or an established business. And if your holdings grow significantly, you can add more keys to your vault through Casa Enterprise at a later time.

Introducing team signing for 3-key vaults

Your treasury should not be dependent on a single person, hardware device, or seed phrase. 

Through Casa Business, your company can involve more than one key holder in your setup using team signing. If you’re an account owner, this gives you the ability to invite a colleague. 

With our vaults, a majority of keys must sign for a transaction to proceed. Here’s an example of how a vault could be distributed:

• Principal: A hardware key housed in a safety deposit box 
• Accountant: A hardware key stored in an office lockbox  
• Casa Recovery Key 

Casa holds one key, the Casa Recovery Key, on your behalf in the event that one of your vault keys is compromised. With Casa Business, you can unlock a signature with the Casa Recovery Key by answering security questions and completing a mandatory waiting period. 

Team signing shields your bitcoin behind multiple required approvals, a smart policy for any business, and it protects from the potential single point of failure of your own personnel.

Find a flexible path to self-custody

Casa believes in making you more sovereign, and we offer you different routes for creating your vault. By default, Casa Business allows you to complete a self-guided onboarding with your own hardware device.

Many bitcoin businesses are operated by people who know their way around bitcoin and hardware wallets on a personal level, and they often feel comfortable with self-guided onboarding. Our app gives you secure instructions for building your vault, and that experience can be even simpler if you opt for a YubiKey in lieu of a hardware wallet.

If you’re trying self-custody for the first time or simply want the peace of mind of a helping hand, you can add a live onboarding call at an additional cost. That way, you know you’re beginning your treasury on the right foot.

Give clarity and visibility to trusted partners

Does your company have its own accountant or outside counsel? You can give them real-time transparency into your assets without giving them access to keys.

In addition to the team signing we mentioned earlier, Casa Business also comes with a straight-forward web dashboard, to which you can invite two view-only users. This feature is great for keeping track of transactions or reconciling balances.

Looking to organize assets for two different purposes? You can create a subaccount within your vault to avoid commingling different lots of your bitcoin.

When you’re holding as a team, it’s critical to have a single source of truth, and our dashboard can be your starting point.

Can’t reach Casa? Recreate your vault 

We were serious when we said your bitcoin should be protected from single points of failure, and that includes Casa itself. We don’t have access to your bitcoin, and your vault is still accessible even if something bad happened to Casa.

Each Casa vault comes with Sovereign Recovery instructions. This guide walks you through every step you need to take to access your bitcoin vault if Casa is ever unreachable for any reason. 

Your bitcoin is online on the blockchain and your keys are in your possession. With these instructions, you can rebuild your vault on your own computer. No Casa, no problem.

Conclusion 

Any business can be a bitcoin business, and Casa is your line of defense. Create your vault and start holding your treasury with peace of mind.
