Lumen Loop's take

Agentic payments represent Stellar's next wave of developer infrastructure, with Kaan Kaçar of the Stellar Development Foundation highlighting x402, the Machine Payment Protocol (MPP), and emerging agentic standards as load-bearing for builders. For every person online, Kaçar notes, there are nearly 100 AI agents navigating the internet—a massive opportunity builders overlook when focusing only on human on-chain adoption. Raven MCP emerges as the essential tool for new developers, serving as a second brain that aggregates documentation, ecosystem data, community intelligence, and playbooks into a single interface. Kaçar emphasizes the weekly Stellar Developers meeting (Thursdays, 11 AM PT) as a gathering point where new and veteran builders connect, alongside the Stellar Developers Discord for real-time collaboration. The culture he describes—simply build things and see what happens—positions infrastructure like Raven and x402 as enablers for the next generation of Stellar products.
