What is self-custody?

Self-custody is the act of assuming personal responsibility for your assets.

When you hold the private keys to your bitcoin, ether, or other cryptocurrency, you ensure you alone can transact with your assets without having to trust a third party, such as an exchange or a custodian.

Frequently asked questions

How is self-custody with Casa different from relying on third-party custodians?

Because Casa only holds one key on your behalf, we do not have the ability to move funds on our own. This means we are non-custodial.

Our team has long understood that if we were custodial, we would be a single point of failure and susceptible to pressure from outside forces. So, we don’t have control of your assets. Instead, we help you provide extra protection with more keys, so you can have peace of mind and control over your assets.

Why can’t I leave my crypto on an exchange? 

When you first buy bitcoin, ethereum, or any other asset, what you have is an IOU. The exchange is obligated to furnish you with the asset once you start a withdrawal. Usually, you can withdraw your assets from these organizations without any problem, but every once in a while, something goes wrong. 

Exchanges and custodians have a poor track record of keeping assets safe from hacks, accidents, and malfeasance. Some prominent examples include the early bitcoin exchange Mt. Gox and the more recent collapses of FTX and Prime Trust.

This doesn’t have to happen with crypto assets. We have tools to protect them and you can verify your ownership on the blockchain. There’s just no way to know what is going on behind the scenes at a crypto exchange or custodian. If you want to have peace of mind and full visibility, the best solution is to hold your assets with a set you control. The answer is self-custody.

Is self-custody more secure than leaving bitcoin on an exchange?

Securing cryptocurrency is different from securing other funds. When you allow another entity to secure your crypto, the same threats that face you as an individual still face the third party, but you no longer have control. Custodial services carry many threats to your assets:

  • Internal attacks within the organization
  • External attacks incentivized by the custodian holding funds of several people
  • Organizational bankruptcy and legal action
  • Collusion against you by the custodian

Holding your own keys allows you to sidestep these third-party risks.

What security measures does Casa have in place to protect private keys and digital assets?

An important part of holding your keys is avoiding single points of failure. You do not want a single unforeseen event to jeopardize your wealth.

Casa vaults use a multisig design that protects your assets with multiple keys. This ensures that your assets remain secure even if one of your devices is lost, stolen, or broken. Each vault is crafted so you can hold your keys on multiple devices in multiple locations for distributed protection. Redundancy is key.Our calling card has long been providing security and usability in tandem. It’s not enough to have a complex solution that leaves your bitcoin and ethereum inaccessible. Complexity is the enemy of security. To this end, we strive to keep the

Casa app as simple and natural as possible and we encourage you to perform health checks on your keys every six months to ensure they are in proper working order.

What backup and recovery solutions does Casa offer to ensure the safekeeping of private keys?

Casa holds one key on your behalf to aid with recovery if one of your keys are compromised, and we offer varying levels of support to assist you with replacing a key. This means that while you’re holding your keys, you’re not completely shouldering the security risk of securing wealth on your own.

To access the Recovery Key, you or someone you trust must first verify data. We also have a required waiting period for recovery signatures to discourage attackers from putting you under duress.

Additionally, self-custody with Casa does not mean you are solely dependent on Casa. Our Sovereign Recovery features allows you to use open-source software to recover your bitcoin independently outside of the Casa app, and we provide these instructions upon the creation of your vault.

What’s the difference between custodial and non-custodial wallets?

Due to the sheer amount of threats to one’s bitcoin or ethereum, many holders will opt for a custodial wallet — one where *another entity* owns their private keys — in an effort to shoulder less risk. If a custodial solution (e.g. an exchange, family office, wealth fund, lender, etc.) holds your funds, it’s their responsibility to secure it.

Unlike custodial crypto wallets, a non-custodial wallet is one in which *you* own the associated private keys. By using a non-custodial wallet, you gain the freedom to do as you wish with your assets while simultaneously taking on the responsibility of securing it. This is why non-custodial wallets are often called self-custodial wallets.

Which cryptocurrencies are compatible with Casa for self-custody?

Members can store bitcoin (BTC) and ethereum (ETH) in their vault at this time. We believe private keys have a bright future in the years ahead, and adoption will eventually surpass even crypto storage. Our team is working to add support for other use cases with a security-first, meticulous approach.
