Build on an Award-Winning Security Model
Our architecture rests on four foundational pillars, each working in tandem to eliminate any single point of failure.
Three Separate Entities Manage Every Wallet
Each vault's signing shards are created in isolation and managed independently by three parties: you, Copper, and a trusted third party. No single entity can unilaterally move assets.
2-of-3 Quorum for Every Transfer
A two-out-of-three consensus is required to sign any asset transfer from your vault. This structural redundancy means no single actor can authorize a transaction alone.
Funds Held in Segregated Vaults
Your assets are held in dedicated wallets at the blockchain level — not pooled, not on Copper's balance sheet.
The Private Key Is Never Assembled
At no point during transaction signing is the private key generated or recreated. The architecture makes single-point compromise structurally impossible.
Configure Vaults to Match Your Needs
Each signing shard can be stored offline or online. Your team configures vault temperatures per signing scheme — choosing from cold, warm, and hot vaults — so you match the right security profile to each position. Hot vault transactions are signed and processed automatically. Cold vault transactions require client-side and Copper authorization, supported by our dedicated client services team who are available 24/7/365.
Add an Additional Layer of Protection With the Policy Engine
Copper's Policy Engine runs on a role-based control framework. You configure roles and permissions for each team member, set per-user transaction limits and time windows, and build multi-step approval workflows that fit how your organization operates. You keep granular control without sacrificing the flexibility your team needs, and Copper enforces your policy.
Access the Ecosystem From Secure Vaults
Secure digital assets, and interact with staking pools, and your usual counterparties — directly from Copper's MPC-secured vaults.
Stake Across Blockchains From Your Vaults
Put assets to work across proof-of-stake networks without ever moving them out of Copper's vault infrastructure.
Settle Peer-to-Peer Directly From Your Vaults
Execute bilateral settlement with institutional counterparties directly from Copper's vault infrastructure — no pre-funding, no unnecessary asset movement.
Insure Every Asset With $500M of Coverage
Copper purchases insurance in partnership with Aon, the world's leading global insurance broker. Our risk-transfer policies are built for the digital asset sector: a bespoke Crypto Crime policy and $500M specie market-based insurance, placed in the Lloyd's of London market.
