At Copper we prioritise both security and speed with our multi-party computation (MPC) technology allowing for the agile movement of assets.

Over 90% of balances in our vault custody, and over 95% of those in our omnibus accounts are held in cold storage. With Copper's dedicated Middle Office team available 24/7/365, cold vault transactions are executed within minutes using our award-winning MPC custody solution.

Key features and benefits:

Our unique vault security model rests on four foundational pillars, each working in tandem to eliminate any single point of failure.

  • Each vault setup is governed by three independent entities, each holding a shard
  • Funds stored in vaults are segregated
  • 2 of 3 shard signing quorum
  • No private key requirement


Each shard can be stored either offline or online. This setup empowers clients to customise their vault settings by selecting from cold, warm, and hot vaults for each asset, ensuring maximum flexibility.

Transactions from hot wallets are signed automatically online and processed instantaneously. In contrast, cold wallet transactions require two manual signatures from the client and Copper. The offline nature of cold wallets generally produces a dilemma between security and operational efficiency. However, with Copper's industry leading technology and response times, we have been consistently executing cold transactions within minutes, effectively eliminating this industry-wide predicament.

In July – September 2024, Copper averaged cold-signing transaction times of under 5 minutes, ensuring that large volumes of assets are safeguarded and readily deployable for maximum capital efficiency.
