🧩On-Chain Orderbook System
Decoding Key Concepts
Secured Finance's Loan Market Platform incorporates an on-chain orderbook system, a pioneering application in the DeFi space. This system facilitates the trading of Zero-Coupon bonds with a specific maturity date. To ensure clarity, we've defined some key terms used on our platform:
What is an Orderbook?
It is an electronic list of buy and sell orders for Zero-Coupon bonds, organized by price level. It enhances transparency by providing visualized information on price, availability, depth of trade, and more.
What is a Borrow Order?
It refers to an order to borrow crypto assets, equivalent to selling a bond on our platform. After pledging sufficient collateral, you can place a sell order, selling a Zero-Coupon bond and receiving the equivalent cash upfront. You then owe the obligation to repay the money with interest at maturity.
What is a Lend Order?
This is an order to lend, equivalent to buying a bond. You buy a Zero-Coupon bond at a discount, which will be redeemable at par at expiration.
What is a Zero-Coupon Bond (ZC bond)?
A Zero-Coupon bond is a debt security that doesn't pay interest (coupons) but is traded at a deep discount, rendering profit at maturity when the bond is redeemed for its full face value. On our platform, bonds will be redeemable at 100.
Why is On-Chain Orderbook so difficult?
The on-chain Orderbook system is often perceived as inefficient due to high gas costs. As a result, many DeFi projects rely on the liquidity pool system (LP) which is a great financial innovation for gathering liquidity. However, the interest rate provided by the pool lacks composability and transparency. Secured Finance has successfully deployed an on-chain orderbook system using the 'lazy evaluation' method, which significantly reduces gas costs.
