Spark: Reinventing DeFi's on-chain capital allocation engine In the DeFi field, @sparkdotfi is not a traditional bank, but a pioneer in on-chain capital allocation, providing users with a new experience of saving, borrowing and lending, unlike banks that pursue profit maximization, Spark is user-centric, committed to giving back returns to users, ensuring full transparency, and optimizing the liquidity and capital efficiency of the DeFi ecosystem through programmatic capital allocation, Spark's unique design makes it stand out in the DeFi market and has attracted widespread attention Through its core products, SparkLend and Spark Liquidity Layer (SLL), Spark allows users to borrow USDS with assets such as ETH and wstETH, or deposit USDS and USDC into the savings bank to obtain sUSDS and sUSDC, and enjoy the stable income brought by the Sky savings rate (SSR, currently 4.5%) Spark's automated rebalancing function can intelligently allocate assets to the optimal strategy pool, simplifying operations, lowering the DeFi threshold, and all transactions are executed on-chain, which is open and transparent, and users can monitor returns and risks in real time Different from the centralized model of banks, Spark sets interest rates through the decentralized governance of the Sky ecosystem to avoid interest rate spikes caused by liquidity fluctuations and ensure fairness and stability Its SLL cross-chain support for Aave, Morpho and other protocols, breaking liquidity silos and improving capital efficiency, Spark is backed by Sky (formerly MakerDAO) $8 billion in assets under management, demonstrating its strong ecological support Spark is not only a lending platform, but also a "liquidity-as-a-service" provider of the DeFi ecosystem.
