Rachel from Circle: Why Stablecoin-as-Gas Changes Everything

Circle just solved one of crypto's biggest UX problems: paying gas fees with the tokens you're already using.

In this episode, we sit down with Rachel Mayer to discuss why they built Arc as an L1 instead of L2, how stablecoin-as-gas unlocks instant settlement, and why bringing $8 trillion/day FX markets onchain changes everything.


We discuss:

- Why Circle Built Arc as an L1 vs L2

- Stablecoin-as-Gas: The Silent Unlock

- Instant Settlement & Privacy Features

- 100+ Launch Partners (Apollo, BNY Mellon, Visa, Mastercard & More)

- Bringing $8 Trillion/Day FX Markets Onchain

- Multi-Currency Stablecoin Strategy

- USDC's Evolution & Global Liquidity Hub Vision
