1/ In #DEFI, borrow/lending is one of the most exciting innovations. Our WatchTower system offers LiquidationMonitor that tracks real time Loan-to-Value-Ratio(LTV) for positions in platforms such as @solendprotocol@HedgeLabs and @HubbleProtocol2/ It does this by looking directly at on-chain states of each borrowed position and comparing it with their corresponding obligation account, at the oracle refresh level
