Decentralized stablecoin USDD has officially announced the addition of Spark as an investment platform to its Smart Allocator mechanism, with over $300 million worth of USDC assets already deployed on Spark. The Smart Allocator has reportedly generated over $5.78 million in cumulative investment returns, demonstrating the mechanism's reliability and the robust growth of its ecosystem. The Smart Allocator is USDD's yield-sharing mechanism, allowing users to earn interest and platform rewards by investing protocol reserve assets in high-quality DeFi projects, which are then returned to the users. All operations are transparent on-chain, allowing users to view details in real time. Additionally, USDD's yield-generating token, sUSDD, offers an APY of up to 12%, providing stable automatic investment returns. More details can be found at https://usdd.io/sa.
