In this episode of Joint Custody – The Digital Asset Dialogues, host Benjamin Duve is joined by Dave Sedacca, Lead of Polkadot Capital Group, for a conversation on how blockchain-native ecosystems are approaching institutional engagement, governance, and long-term financial sustainability.

The discussion looks at how decentralized networks manage treasuries, make capital allocation decisions, and translate protocol economics into real-world adoption – and what these approaches can teach traditional financial institutions. It also explores what institutions often misunderstand when engaging with decentralized ecosystems, and where the biggest gaps still exist between on-chain design and off-chain expectations.

In this episode, the conversation explores how Polkadot is positioning itself for institutional participation, how on-chain governance shapes decision-making at scale, and what the next phase of digital asset infrastructure will require from both networks and market participants.
