Casa
Casa, Inc.
Casa is a self-custody multisig service founded in 2018, with apps on iOS, Android and Web, which as of 2026 states more than 40,000 clients and over 10 billion dollars in protected assets. The model is geo-distributed multi-key: keys are spread across multiple devices and locations, so that no single compromised key or password can move the funds. Casa adds inheritance planning (family access after death), shared accounts and SOC 2 Type II certification. Note: Casa is no longer Bitcoin-only. Besides Bitcoin it now also handles Ethereum and stablecoins, so it counts as a multi-asset wallet. The integrated buy/sell services are run by a partner (Zero Hash) and involve KYC, but custody itself stays self-custody. It is offered by subscription in three tiers: Standard, Premium and Private Client.

Strengths
- Self-custody multisig with geo-distributed keys: no single compromised key moves the funds; built-in inheritance planning; SOC 2 Type II certification; company active since 2018 with a large client base; apps on iOS, Android and Web.
- Self-custody: funds stay in your wallet — the platform cannot touch them.

In its favour: self-custody multisig with geo-distributed keys: no single compromised key moves the funds; built-in inheritance planning; SOC 2 Type II certification; company active since 2018 with a large client base; apps on iOS, Android and Web.

FAQ
Is Casa still a Bitcoin-only wallet?
No. Casa comes from the Bitcoin world but is now multi-asset: besides Bitcoin it also handles Ethereum and stablecoins. If you are looking for a strictly Bitcoin-only wallet, this is something to consider.
How does Casa's multi-key security work?
Casa uses multisig with geo-distributed keys across several devices and locations. Moving funds requires signatures from multiple keys, so a single compromised key or password is not enough for an attacker. The keys stay yours: Casa is self-custody, not custodial.
Does Casa require KYC?
For self-custody itself no KYC is required. However the integrated crypto buy and sell services are run by a partner (Zero Hash) that applies its own KYC checks. Casa is offered by subscription in three tiers: Standard, Premium and Private Client.
