Built on Caravan: Why Evoke Uses Open-Source Multisig
Evoke Vault is built on Caravan, an open-source multisig coordination framework. This is a deliberate choice that protects you from vendor lock-in and ensures your Bitcoin remains accessible even in worst-case scenarios.
What is Caravan?
Caravan is an open-source tool for creating, managing, and signing Bitcoin multisig transactions. It was developed by Unchained Capital and has become a widely used standard in the Bitcoin custody industry. The code is publicly available, auditable, and free to use.
What Caravan means for you
- No vendor lock-in. Your wallet configuration is based on open standards. You can export your wallet details and use them with any compatible Bitcoin software.
- Independently verifiable. The code that manages your multisig wallet is publicly available and auditable. You don't have to trust Evoke's proprietary code — because there isn't any for the core wallet logic.
- Portable. If Evoke ceased to exist tomorrow, you could reconstruct your multisig wallet using Caravan or any compatible tool and your two personal keys.
- Industry-standard. Caravan isn't a proprietary experiment — it's used by multiple Bitcoin custody providers, which means knowledge of how to use it is widely available.
Why Evoke chose Caravan over a proprietary system
Some Bitcoin custody services build their own proprietary multisig software. This creates a hidden risk: if the service fails, users may find themselves unable to reconstruct their wallets without the company's help. By building on Caravan, Evoke ensures that our users are never dependent on our continued operation for access to their Bitcoin.
This is especially important for inheritance planning — your heirs may need to access your Bitcoin 10, 20, or 50 years from now, when Evoke (or any company) may or may not still exist.
The philosophy: A good Bitcoin custody service should make itself as replaceable as possible. Evoke's role is to provide tooling, documentation, and support — not to be a single point of failure.
