COLDCARD + Trident: Policy-Driven Custody
AnchorWatch now supports COLDCARD Mk4 and COLDCARD Q as signing devices for Trident Vaults.
If you have been holding out on setting up a Trident Vault until COLDCARD was supported, that wait is over. You can now pair one of the most trusted signing devices in Bitcoin with institutional-grade custody policy and Lloyd's of London-backed insurance.
Choose Your Vault Configuration
AnchorWatch offers two vault types that support COLDCARD.
The 1 Key Vault is designed for individuals who want straightforward self-custody with enforced policy. You hold a single signing key on your COLDCARD. AnchorWatch co-signs to enforce spending conditions and recovery rules. Simple to manage, with the full protection of the Trident architecture underneath.
The 3 Key Vault is built for those who want distributed control. Signing authority is spread across three independent keysets, requiring multiple parties to authorize a transaction. This configuration is well suited for high-value holdings, shared custody arrangements, family trusts, and anyone who wants to eliminate single points of failure entirely.
Both vault types support COLDCARD Mk4 and COLDCARD Q.
What Trident Adds
Trident is AnchorWatch's Bitcoin-native vault architecture, built on Miniscript and enforced on-chain by Bitcoin itself.
Your spending conditions, recovery paths, and inheritance rules are not stored in a database or dependent on AnchorWatch staying in business. They live in the protocol. COLDCARD signs. Trident governs. No single party can move your funds unilaterally. Not you alone. Not AnchorWatch. That is by design.
What This Means in Practice
If your device is lost, there is a recovery path. If you face coercion, time-locked conditions limit what can be forced. Every Trident Vault includes inheritance planning as a core feature, not an add-on. Your heirs have a defined, protocol-enforced path to access your Bitcoin when the time comes. This is built into every vault configuration from day one.
Trident Vaults are available globally. For clients in the United States, you can add Lloyd's of London-backed insurance directly to your vault, with coverage starting at $250,000 and available up to $100 million per vault. It is optional, adjustable, and priced separately so you always know exactly what you are paying for.
