Circle just launched Nanopayments on testnet. Gas-free USDC micro-transfers down to $0.000001, built specifically for AI agents. This is validation. When a $76 billion stablecoin issuer builds infrastructure for AI agent payments, they're not speculating. They're responding to demand that already exists. The agent economy isn't coming. It's here. And the infrastructure race is on. We didn't wait for the giants to validate the thesis. We built while others were still asking if the market was real. Circle's move confirms what we've known: AI agents need native payment rails. Micro-transactions at scale. Instant settlement without human approval loops.
