Copper

• Name: Copper
• URL: https://copper.co/
• Category: institutional custody / off-exchange settlement / collateral-management and prime infrastructure
• Summary: Copper is institutional settlement plumbing wrapped around MPC custody. ClearLoop, venue reachability, and collateral mobility are the point. The custody layer is just the thing that makes the rest of the operating stack credible.
• What it does:
  • Provides institutional digital-asset custody built around Copper’s MPC wallet architecture
  • Runs ClearLoop, an off-exchange settlement system that lets institutions trade on centralized venues without prefunding those venues directly
  • Exposes a broad developer surface for organizations, portfolios, wallets, orders, loans, addresses, counterparties, and deposit targets
  • Supports collateral movement, lending, staking, and other post-trade workflows on top of the custody layer
  • Packages approvals, organization modeling, and address-book policy into the same operating stack as asset control
• Key claims:
  • Copper markets itself as institutional custody, prime services, and collateral management rather than a simple wallet vendor
  • ClearLoop is presented as the core differentiator: trade on centralized exchanges without moving assets out of Copper’s MPC custody until needed
  • The developer docs model the product as a workflow-heavy institutional platform, not a narrow custody API
  • Public llms.txt and API materials expose first-class surfaces for network counterparties, orders, lending, and other operational primitives beyond storage
  • The practical read is simple: Copper matters when custody really means venue access, collateral routing, and policy wrapped into one shell
• Whitepaper: No classic standalone whitepaper or litepaper was found during this pass. The strongest primary materials were Copper’s official site, product pages, developer portal, and public llms.txt / API index; see ../whitepapers/copper-primary-sources-2026-04-26.md.

Internal linkages

• fireblocks — stronger institutional control-plane anchor

• bitgo — closer custody-and-settlement peer with more established category weight

• cobo — useful contrast where the question is wallet-platform breadth versus venue-and-collateral routing focus
