# Major Matters

> Major Matters covers the infrastructure being built at the intersection of payments, AI, and commerce. Infrastructure-first, hype-skeptical, evidence-led: I verify claims against primary sources, name the gap between what is announced and what works, and publish live trackers and direct answers that update instead of aging. Written by Charlie Major. Tagline: Payments. AI. Commerce. Decoded.

## What I publish

- [Answers](https://majormatters.co/answers): short, dated, direct answers to the questions people and AI assistants actually ask (agent authentication, settlement finality, the transaction lifecycle, evaluating agent platforms). The first paragraph of each answer is written to be quotable standalone.
