flow-credit-markets

Users holding an asset are seeking higher returns than the direct yield opportunities of that asset. Using the asset as collateral to borrow a debt token can gain those higher yields, but requires permanent user interaction to keep asset exposure, maximize yield and prevent liquidation. We utilize flow's unique feature of scheduled transactions to automate this process, constantly adjusting the position to keep asset exposure at 100%, maximizing the potential debt to maximize yield while making sure the user doesn’t get liquidated. This will bring TVL and users to Flow, provide a revenue stream through fees, and demonstrate a practical application of Flow’s unique feature of scheduled transactions.
