[Spark: When on-chain interest becomes a public asset] In the hustle and bustle of the DeFi market, where most protocols are vying for TVL, driving up yields, and engaging users with aggressive incentives, Spark is trying to do something cool, but systemic: make "interest" one of the most important public infrastructures on the chain. 1. What does Spark do? Spark is a lending protocol built around DAI and USDS, but its core is not about matching loans, but about how to organize the flow of funds on the chain: (1) You can deposit DAI or USDC to get a long-term, stable, and nearly 4.5% annualized return; (2) You can use ETH, stETH, rETH and other assets as collateral to lend USDS; (3) The system will also send part of the capital flow to protocols such as Aave to form a closed loop of income. Spark is built as an "on-chain spread bank" system - not to serve individuals, but to serve the entire stablecoin ecosystem. 2. What is so special about Spark? It's not so much another Aave as it is an extension of MakerDAO. Spark itself is managed by Sky Protocol, using Maker's DSR rates, governance framework, Oracle modules, and even a liquidation mechanism. You can think of it as: Maker is the central bank and Spark is the commercial bank. Spark is the main distribution and revenue landing tool of the stablecoin DAI. 3. Why is it worth paying attention to? Because Spark is not a question of "whether it will go up", but "whether it will be long-lasting". (1) it doesn't take off on memes, it's driven by real spreads; (2) its income is not obtained by market making, but by real lending and inter-protocol collaboration; (3) It is not designed for speculation, but to be the core circulation platform of DAI's long-term interest rate anchor. Fourth, summary If you're looking for the kind of "get in today, double tomorrow" project, Spark is clearly not for you. But if you're thinking: In the future, can the on-chain interest market be relied on by the entire Web3 like the U.S. Treasury interest rate? Then you will most likely find some structural designs in Spark's model that are worth long-term observation and study. @sparkdotfi @cookiedotfun #Spark #sparkdotfi #SparkFinance #Cookie
