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.
