Protocol layer:- The order object that makers create and takers present to the bZx contract.

  • Escrow contract — Holding funds of lenders
  • Smart contract — Logic for disbursement of interest.

Oracle layer:- Price feeds and on-chain liquidity. Bounty hunter monitors solvency of margin account. A gatekeeper that uses the DEX price feeds to allow only honest and accurate bounty hunters to initiate liquidations. A guarantee fund that pays out in the rare circumstance that a lender may lose money.
