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 — across 40+ networks and 500+ digital assets.
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.
Tokenized Assets are digital representations of traditional funds that hold low-risk, short-term instruments. Our institutional-grade secure storage supports a range of these tokens — so treasuries and fund managers can hold them with confidence.
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.
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.
Secure more than 500+ digital assets across 40+ blockchains, and interact with exchanges, DeFi protocols, staking pools, and your usual counterparties — directly from Copper's MPC-secured vaults.
Put assets to work across 20+ proof-of-stake networks without ever moving them out of Copper's vault infrastructure.
Connect to dApps and DeFi protocols across chains from Copper's MPC-secured environment.
Execute bilateral settlement with institutional counterparties directly from Copper's vault infrastructure — no pre-funding, no unnecessary asset movement.
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.
Copper works with institutions that demand infrastructure they can rely on, operational support they can count on, and a partner that understands how these markets move.
The NEAR foundation has a commitment to the community of working with the best partners in the blockchain space. Copper is recognised as one of the leading custodians in the space, and their 100% commitment to its clients, echoes our commitment to the NEAR ecosystem.
