According to Foresight News, MakerDAO lending protocol Spark Protocol has integrated LI.FI, enabling users to transfer USDT and USDC directly and seamlessly into sDAI (Savings Dai) without leaving the Spark platform. sDAI is a tokenized representation of the Dai Savings Rate (DSR) provided by Dai deposited into MakerDAO, allowing users to earn returns on DSR deposits while still being able to use it in DeFi.
