Building Payment Rails That Banks & Fintech Actually Want to Use | Marc Boiron
In this episode of Talking Tokens, Jacquelyn Melinek speaks with Marc Boiron, CEO of Polygon Labs, about the company's expansion into payments through its new Open Money Stack and why connecting onchain systems to real world finance is critical for keeping capital onchain. Marc explains why blockchains, stablecoins, and wallets are converging to make payments easier than traditional correspondent banking networks, and how Polygon's acquisitions of Coinme and Sequence can create a unified API for enterprises. He walks through why general purpose blockchains can't excel at everything, how Polygon is doubling down on its payments reputation, and why the next inflection point happens when merchants, businesses, and developing countries adopt stablecoins at scale. The conversation covers cross-border payments, FX markets, enterprise treasury strategies, the future of Visa and SWIFT, and why blockchain infrastructure will capture hundreds of billions in network value over the next decade.

Evernorth Has 473 Million XRP And An Argument to Why Idle Capital Should Not Exist | Asheesh Birla
On today's Talking Tokens, Jacquelyn sits down with Asheesh Birla, CEO of Evernorth, the Ripple-backed digital asset treasury firm holding roughly 473 million XRP tokens, to talk about why he thinks we've finally hit the inflection point that blockchain has been building toward for over a decade.

Why Aave V4 Is Built Like a Central Bank for DeFi | Stani Kulechov
On today's Talking Tokens, we're sharing Jacquelyn’s Proof of Talk chat with Stani Kulechov, founder and CEO of Aave Labs, to break down why Aave V4 moved away from a single monolithic protocol toward a hub and spoke model that works more like a central bank. Stani gets into why a lot of centralized lenders didn't hold up through both the FTX collapse and last October's market unwind. Then Stani explains why he thinks the next real growth phase for DeFi comes from financing things like AI infrastructure, tokenized equity, and credit for businesses that have never had access to capital this efficient before.
