Presented by Stablecon; Powered by BVNK.

In this episode of Money Code, hosts Chuk Okpalugo and Raj Parekh sit down with Erik Reppel, Head of Engineering for Coinbase's Developer Platform and the creator of x402 — the open payment protocol that just joined the Linux Foundation with Google, Stripe, Visa, Mastercard, AWS, and Cloudflare as founding members.

They unpack why Erik designed x402 to capture zero value, how "the wallet is a universal API key" that eliminates sign-up friction for a new class of non-technical builders, and what the "agentic premium" means for companies leaving money on the table with free tiers.
