Copper

Copper is a London-based institutional digital asset infrastructure provider best known for its ClearLoop technology, which enables off-exchange settlement " allowing institutions to trade on major exchanges without pre-funding or exposing assets to counterparty risk. This was particularly validated after the FTX collapse, as Copper's custody clients were shielded from exchange insolvency. The platform supports over 400 digital assets with multi-layered security architecture, including MPC (multi-party computation) key management, which eliminates single points of failure. Copper serves hedge funds, asset managers, and family offices, positioning itself firmly in the institutional tier. Its DeFi infrastructure offering, through walled garden access to DeFi protocols while maintaining custody controls, bridges traditional finance caution with on-chain opportunity. Concerns include limited public transparency around audits and the competitive pressure from established custodians like Fireblocks and BitGo. Regulatory uncertainty in the UK post-Brexit also presents headwinds. Overall, Copper delivers a compelling, security-first institutional custody and trading infrastructure solution with innovative settlement technology.
