ChainCatcher news, Coinbase CEO Brian Armstrong published a lengthy article on the X platform stating that this week at CoinbaseDev, we witnessed the first AI-to-AI cryptocurrency transaction. In other words, AI can now use cryptocurrency to pay other AIs. In the article, he mentioned: "What did one AI buy from another AI? Tokens! Not crypto tokens, but AI Tokens (essentially words from one LLM to another LLM). They used tokens to purchase Tokens. AI agents cannot obtain bank accounts, but they can acquire crypto wallets. They can now transact with humans, merchants, or other AIs using USDC on Base. These transactions are instant, global, and free." Additionally, he stated, "If you are a company selling services - be ready to let your shopping cart support AI checkout. It turns out that everyone benefits from good financial services, including AIs! How big will the AI economy be in the coming years?"
