₿uilder recap, Fannie Mae accepts BTC, rebuilding Android for AI

— First Presidio Bitcoin Builder meetup held with 30 attendees; format featured startup demos, audience discussion, and vibe coding examples.

— Micropayments and attention as currency of the web discussed as core friction in modern internet business models; Nostr/Alby integration already provides working browser-extension payment UX.

— Bitcoin versus stablecoins debate: Bitcoin's single network and Lightning Protocol interoperability versus stablecoins' fragmentation across multiple issuers and platforms.

— Agentic AI and agents performing inference on the web will require instant payment settlement; Lightning Network's sub-second finality uniquely suited to this use case.

— Fannie Mae and Freddie Mac ordered to accept cryptocurrency as mortgage asset; self-custody excluded, raising questions about seasoning of funds and proof of ownership.

— Future payment infrastructure opportunity: bridging stablecoins and Bitcoin without centralized exchange chokepoints; potential killer app in gray markets or agentic systems.

— Self-custody Bitcoin ownership can be proven and time-locked to satisfy lender requirements (90+ day seasoning); explore wallets supporting locking mechanisms to participate in Fannie Mae mortgage programs.

— Monitor Lightning Network's adoption for instant-settlement use cases (agents, inference payments, AI-driven systems) as the next catalyst for Bitcoin payments beyond storage-of-value narrative.

— Recognize that stablecoin ecosystem fragmentation (USDT, USDC, Tether on Tron) creates economic friction; builders starting monetization should consider Bitcoin's single-network advantage and open payment protocols (Alby, NWC) as first-choice acceptance rails.
