Choose a plan

Protect yourself from web3 hacks and exchange collapses

More than $6 billion in crypto has been stolen since 2021, and billions more were lost in the collapses of FTX, Celsius, and other custodians.

With a Casa vault, you can protect your ETH from custodial risk by holding your own keys.

Hold ETH, BTC, and stablecoins with one app

No more bouncing from wallet to wallet. With Casa, you can hold different assets whether you’re a trader or long-term investor.

*Casa currently supports BTC, ETH, USDT and USDC assets.

How is Casa better
than other wallets?

Multiple keys

Most ETH wallets have one key. This creates a single point of failure. Casa’s ETH vaults use multisig which means transactions are unable to be sent with a single device.

Multiple devices = better protection

Our 3-key vaults use a phone, a hardware wallet, and the Casa Recovery Key, of which two are required to send a transaction. With Casa, you could lose your phone or your hardware wallet and still recover your crypto.

We'll hold a key for you

Casa vaults come with the Casa Recovery Key, which Casa holds on your behalf. That way, if something bad happens to one of your other keys, you can still recover your assets.

Security options for every amount

We know you don’t buy ETH just to hold it — you sometimes need quick access to it. Casa has both a mobile wallet and a multi-key vault, so you can separate short-term ETH and long-term holdings.

Frequently asked questions

Why is ETH self-custody important?

Not your keys, not your coins. Cryptocurrency is different from other types of property. Ethereum only exists in cyberspace, and your ability to spend it rests with your key, or your digital code to access your ETH.

Self-custody allows you to own your digital assets completely on your own, without the need of a third party custodian (like an exchange). Custodians always have a back-door to your assets. If they are forced (by a subpoena for example) to release funds they will be able to. Casa’s self-custody vaults do not have this “back-door” access. Your assets are under your control. Even if a governing body were to come after Casa, or if Casa was hacked — your funds would be completely safe under your own control.

What hardware wallets can I use with Casa?

With Casa, you can use popular hardware brands like Trezor or Ledger to secure your ETH. We recommend using different types of devices in your vaults for more robust security. Because we support multiple brands, Casa can protect your assets from damaged devices, individual device exploits, and failed software updates.

Please see our most up-to-date list here.

What assets can I secure with Casa?

You can secure Tether (USDT) and USD Coin (USDC) as ERC-20 tokens in your ETH vault. In the same account, you can secure bitcoin (BTC) within a bitcoin vault. This gives you the simplest, most efficient storage for your digital assets.

Is Casa a cold storage wallet? 

Yes, our multi-key vaults are comprised of multiple devices held in cold storage, such as one or more hardware wallets and the Casa Recovery Key.

If your ETH is on a single key connected to the internet, your ETH is exposed to hacking risk. Our multi-key vaults keep your keys in cold storage (offline) until you’re ready to send funds.

How does Casa work? 

Casa vaults are built with a multisig design. This security protocol requires multiple signatures to send transactions. For ETH vaults, we implement this setup with the Safe smart contract, a battle-tested design that secures billions of dollars in assets, and multiple devices, such as your mobile device and one or more hardware wallets, such as a Trezor or Ledger. Learn more about how Casa works here.

Is Casa a custodial wallet?

Casa is non-custodial which means you are in control of your keys. Because our vaults use multiple keys (multisig), you’re able to distribute those keys to prevent single points of failure. Currently, Casa offers a 2-of-3 (Standard) and a 3-of-5 (Premium) multi-key vault. Meaning, you will need to sign with a minimum of 2 keys of your total of 3 in order to send out assets from your vault.

In our multi-key vaults, we hold only one key — the Casa Recovery Key — and this key isn’t enough to send transactions on its own, so your assets are in your control, the way it should be.
