Continuing on my series about @sparkdotfi and $SPK token, with the next topic. Building the Engine: Vaults, Lending, and Capital Deployment The rollout of Spark's core products reflected a careful, layered approach. First, they introduced Spark Savings Vaults, places where users could deposit stablecoins and receive interest bearing versions like sUSDC or sDAI. These weren't flashy degen farms. They were designed to be boring in the best possible way: predictable, transparent, and efficient. Then came SparkLend, a money market built from the ground up to be cross-chain and over-collateralized. Rates weren't determined by the usual utilization curve, but rather governed by the community. It felt like an evolution of Maker's DSR, but more flexible and more open. The third pillar, one that still doesn't get enough attention, is Spark's active capital deployment engine. Rather than just holding deposits passively, Spark routes capital to platforms like Aave, Morpho, and Ethena. It does this on-chain, with every move visible. It's like Yearn's vault strategy, but cleaner, auditable, and optimized for stablecoins. Next part of this series coming tomorrow. Stay tuned!
