In this episode of WuBlockchain Podcast, Sam MacPherson, co-founder of Phoenix Labs, shares how Spark has evolved from a DeFi lending protocol into a capital allocator managing nearly $4B across DeFi, CeFi, and RWA. He explains the Spark Liquidity Layer's role in optimizing yield--especially through tokenized U.S. Treasuries--while maintaining a 25% cash reserve to ensure stability. Sam discusses the platform's modular governance via the Sky-Star system, its push into the APAC market, and the upcoming SPK token launch for staking and governance. Transparency and on-chain auditability remain Spark's core strengths over traditional finance. Text summary
