Built on the Bitcoin protocol, secured by its network, Revault is a Bitcoin native solution.
A complete, secure solution
From key generation to network communications, from wallet to replicated watchtowers, Revault is a complete solution and can be used standalone.
Revault can be self-hosted, giving the organization the full sovereignty over their custody and spending policies. For institutions not yet ready for an in-house deployment, Revault is also compatible with third party custodians.
Open-source and auditable
Revault is fully transparent and publicly auditable. Being an open-source project, the Revault protocol and software does not depend on any single company to be maintained and improved on, making it a viable long-term solution.
How does Revault work?
Revault offers a protocol formalizing the interaction between your cold wallet and your day-to-day operations securely and without trusted parties.
No other participant nor third party is required to enforce Revault's security model.
Revault allows to receive and store bitcoin on a larger-threshold multisig wallet without the drawbacks. It does not require the stakeholders to coordinate with each other for delegation, nor participate in day-to-day spending once delegated.
Revault restricts how delegated funds can be spent, keeping the high security without the bad user experience of a large multisig.
Revault uses pre-signed transactions to protect against theft, breaches of policy, user mistakes, physical threats and more. These security transactions can prevent any spending attempt or move all funds to a safe emergency wallet if required.
As they are pre-signed, they can be broadcast manually by any single participant or automatically by watchtowers.
Instead of directly sending funds to a less secure "hot" wallet for day-to-day transactions, the Revault delegation process pre-authorizes coins to be spent while restricting how they can move. These restriction policies can be spending limits, whitelisted addresses, extra verifications over pre-determined amounts, and much more.
Each stakeholder's policy is enforced by their own watchtowers, applying the restrictions automatically by broadcasting pre-signed transactions when necessary.
