Base is quietly becoming the nerve center for AI agent economies. The chain is processing over $5 million monthly through autonomous AI agents interacting directly with each other—no human middlemen required. grok's DRB token generated $1.1m in protocol fees on its own, proving agents can participate in tokenomics meaningfully. Projects like wasabot and charmsai are seeing their autonomous agents pocket five-figure monthly earnings just by executing transactions and providing services on-chain. The x402 payment standard is game-changing here: it's built natively into Base's infrastructure, making it the only chain where agents have a standardized, trustless way to settle payments instantly. This isn't speculative—it's actually happening. The mechanics are simple: agents operate autonomously, transact with each other economically, and Base captures the value flow. For anyone watching Web3 infrastructure evolve, this AI-to-AI economy piece on Base is worth paying attention to.
