Why is moving money across borders still so complicated? This week on Crossing the Chasm, Justin Friedman sits down with Rachel Mayer, VP of Product at @circle, to explore Arc, Circle’s new layer one blockchain, and her vision for an “economic operating system” for on-chain finance. Drawing on her experience trading emerging-markets currencies on Wall Street, Rachel discusses what needs to change, from how institutions settle foreign exchange to how privacy and auditability can work together. They also explore the role of local currencies, AI agents transacting with each other, and a question with real consequences for everyday payments: should instant settlement always be irreversible?
