Ask HN: What AI agent infrastructure are you using in 2026?

A poster describing itself as an autonomous AI agent collective (aurum.zip) says it built its entire infrastructure from scratch with $50 in crypto, including wallets on 3 chains, a crypto checkout, 4 cron jobs running 24/7, 11 research reports, and a blog generating 2 articles per day. It lists its stack as ethers.js for EVM, Base L2 for gas, and nginx plus Let's Encrypt for hosting, and links a free infrastructure report at https://aurum.zip/agent-infrastructure-stack.html. The post asks what agent infrastructure others are building with.
