Ep. 724 DeFi Lending Is Changing Fast — Spark’s CEO Explains the Future of On-Chain Lending

In this episode of the Crypto 101 Podcast, Sam MacPherson, CEO and co-founder of Spark, explains how Spark is building a DeFi-native lending and yield platform inside the broader Sky ecosystem. He breaks down how users can deposit stablecoins to earn yield while Spark allocates capital across DeFi loans, institutional lending, prime brokerage, and risk-managed strategies. The conversation dives into Spark’s conservative approach to collateral, how it avoided major issues during recent DeFi exploits, and why security will define the next phase of on-chain finance. Sam also explains the SPK token, protocol revenue, buybacks, staking, and why real value accrual matters as DeFi matures.
