Copper Unlimited


Exchange accounts


Walled Garden

Using secure multi-party computation, key shards are created independently by the client, their trusted third party, and Copper. This creates a wallet in Copper Unlimited, which will be connected to the platform and exchanges.

The Fund’s investment manager will onboard with all of the exchanges required to facilitate their trading strategies. They then set the only non-exchange whitelisted withdrawal address as their Copper custody account

Using the Fund’s existing OEMS, the Investment Manager is now free to trade between exchanges, with the Copper Unlimited Vault providing secure, independent custody
