They provide a full breakdown of the Spark stack, explaining how the protocol deploys over $3 billion from Sky's balance sheet to generate sustainable, risk-adjusted yield across DeFi, CeFi, and RWA markets. The session offers a deep dive into the architecture of Spark Savings v2, the Spark Liquidity Layer, and the SparkLend money market. The team explains how their ERC-4626 compliant vaults are designed for safety, transparency, and deep liquidity, making them ideal building blocks for other protocols, wallets, and exchanges. This is a must-watch for any developer looking to understand how institutional-grade yield is generated and how to integrate it into their own dApps.
