Users who choose to borrow from the cheapest provider today can find themselves paying a lot more interest just a few days after. 2) High management costs - Managing a debt position is time-consuming. It requires resources to monitor borrowing rates and to take appropriate actions based on market conditions. High gas fees increase transaction costs. - Fuji DAO built the first borrowing aggregator. - It aims to optimize loan expenses for DeFi users. - The protocol achieves this by constantly monitoring borrow markets and whenever there is a better rate, it automatically refinances the whole pool of debt. - The advantages of Fuji compared to interacting directly with a base protocol are: 1) cost optimization - minimize the interest paid by borrowers 2) economics of scale - pooling funds together reduce the transactional costs by sharing fixed costs 3) time-saving - removal of constant attention users need to pay to find optimal rates 4) smooth UX - manage easily all debt positions from one place - Fuji DAO creates vaults where users deposit a single asset as collateral and borrow against it another asset. - For example, in the ETH/DAI vault, users deposit ETH and borrow DAI. - Thus, isolating debt positions allows for better risk management and the most effective interest rate optimizations. - When users borrow from a Fuji vault, the needed liquidity gets sourced directly from the base protocol proposing the best rate (Compound, Aave, dYdX, and more to come). - The protocol keeps track of users' individual positions and assures the overall vault's health through a classical liquidation mechanism. - To avoid liquidation, users need to maintain the proportion of their debt to the amount of collateral they provided above a certain threshold. - When market conditions change and there's a provider with a lower borrow rate for a certain asset, the protocol triggers a rebalance operation and refinances the whole position of the vault. - In that way, users instantaneously get a better rate on their loans without the need to take any action on their side.Host: Justin Havins aka Crypto TexanAV Engineer: Aaron PettijohnPolygon official channel:Website: polygon.technologyTwitter: twitter.com/0xPolygonTelegram Community: t.me/polygonofficialTelegram announcement: t.me/PolygonAnnouncementsReddit: www.reddit.com/r/0xPolygon/Discord: discord.com/invite/polygonFacebook: www.facebook.com/0xPolygon.Technology/ This is a public episode.
