According to Foresight News, Spark Protocol, a lending protocol of MakerDAO, has integrated with LI.FI. This integration allows users to seamlessly convert USDT and USDC into sDAI (Savings Dai) without leaving the Spark platform. sDAI is a tokenized representation of Dai deposited in MakerDAO's Dai Savings Rate (DSR). This allows users to earn returns on DSR deposits while still being able to use it within the DeFi ecosystem.
