#32: David Reising, Lotus Protocol | Tranched Lending and the Missing Middle in DeFi Credit

Episode Description Today’s guest is David Reising, founder and CEO of Lotus Protocol. Ryan and David get into why isolated lending markets keep converging on the same handful of pairs, how Lotus prices risk on liquidation thresholds, and why the recent string of DeFi exploits (Aave, Resolv, Stream Finance) is forcing a real rethink of how curators underwrite collateral. They also cover productive debt and the LotusUSD base rate, what David learned relaunching hyETH on Morpho with Gauntlet at Index Coop, and the case for going direct to markets in an agentic world.

#29: Jeremiah Smith, OpenCover | Why 99.95% of DeFi Is Uninsured

Today’s guest is Jeremiah Smith, co-founder and CEO of OpenCover. Jeremiah explains why less than 0.05% of DeFi TVL is insured, walks through how OpenCover’s new “covered vaults” primitive eliminates the upfront cost and manual renewal problems that killed DeFi insurance adoption, and breaks down the Nexus Mutual underwriting stack that backs it all. Ryan and Jeremiah also discuss the Resolv USR fallout, the xUSD claims payout, and why embedded risk transfer is becoming table stakes for any product offering DeFi yield.

#28: Octave Mesnard, Jumper | A consumer hub vision, building for prosumers & multi-chain myths

EPISODE DESCRIPTION: Today’s guest is Octave Mesnard, Head of Strategy and Consumer Products at Jumper Exchange. We discuss Jumper’s evolution from a thin cross-chain swap interface into a full on-chain consumer hub, the real challenges of building consumer DeFi products at the right time, and why Octave thinks the multi-chain future will consolidate around far fewer chains than anyone expected.

[02:17] Are there any parallels between catastrophe bonds and crypto insurance? [05:43] Tell us about Valha and Kook Exchange — what did you set out to solve? [09:10] You had both an API and a consumer interface — was that intentional? [12:05] Before joining LiFi, you were already working with them. How did that come about and how did you end up joining? [13:34] When you joined, did you already have a vision for what you wanted Jumper to become? [15:23] How do you think about where Jumper goes from here — browser, desktop, mobile? [19:43] Does the Robinhood comparison resonate — one place where users manage everything? [22:07] Who actually is the “normie” user in crypto? [23:42] So Jumper started as a thin layer on LiFi’s stack — is Earn the attempt to thicken that? [26:21] How have you thought about curation on Jumper Earn — what gets listed and what stays out? [29:10] How do you think about risk scoring more broadly across DeFi? [34:46] What are your concerns around RWAs coming into DeFi? [37:28] How do you view the competitive landscape for swapping and bridging today? [40:22] How did you think about working with vaults.fyi and how do you approach partnerships generally? [42:01] Outside of your role at Jumper, what’s catching your attention in DeFi right now? [44:22] You work in interoperability — do you have a contrarian view on the multi-chain future?
