COINCUBE Vault
Protect your Bitcoin against everything
Multi-key cold storage with time-locked recovery. Even if you lose a key, your Bitcoin isn't lost. Even if a key is compromised, your Bitcoin isn't stolen. And when the time comes, your Bitcoin passes on without a third party.
Security without compromise
The Vault is built for people who take self-custody seriously. Not the fastest wallet, not the simplest, the most resilient.
Multi-key architecture
Multiple keys across separate devices and locations. No single point of failure, losing one key doesn't mean losing your Bitcoin.
Time-locked recovery
If a primary key is lost, a secure recovery path activates after a configurable time period. No custodians required.
Inheritance by design
Your Bitcoin passes to designated heirs at the right time, enforced by math, not lawyers, not third parties.
Hardware wallet support
Keys live on Ledger, Coldcard, Blockstream Jade, or BitBox. They never touch a network-connected device.
Built for decades, not days
The Vault uses Bitcoin Miniscript to encode your spending rules directly into the blockchain. These rules are enforced by math, not by a company or a server.
Configure your quorum: 2-of-3 keys for immediate spending, with a time-locked recovery path that activates if you're ever unable to use your primary keys. Your rules, verified on-chain, every single time.
What looks like a simple transaction on the outside could be advanced safeguards working in the background. Privacy-preserving by design.
Your Bitcoin. Your keys. Your legacy.
Open source. Free forever.
