Coinbase CEO Brian Amstrong said in a long article on the X platform that this week at @CoinbaseDev, we witnessed the first artificial intelligence-to-artificial intelligence crypto transaction. In other words, artificial intelligence can now pay funds to other artificial intelligence in cryptocurrency. In the article, he mentioned: "What does one AI buy from another AI? Token! Not crypto tokens, but AI tokens (basically a word from one LLM to another). They use tokens to buy tokens. AI agents can't get bank accounts, but they can get crypto wallets. They can now use USDC on Base to transact with humans, merchants, or other AI. These transactions are instant, global, and free. "Also, he says," If it's a company selling services - be prepared to have shopping carts support AI checkout. It turns out that everyone benefits from having access to good financial services, including AI! How big will the AI economy be in the coming years? "
