According to CoinMeta, Coinbase proposed the concept of "proxy finance" ( AiFi ), aiming to provide payment, trading, and fund management infrastructure for AI proxies. Coinbase supports AI proxies with products such as Coinbase Advisor, Coinbase, for, Agents, X402, and Coinbase Business for portfolio management, strategy execution, machine-to-machine payments, and merchant collections. X402 has processed over 205 million transactions, with a transaction volume of 53 million US dollars, covering 200,000 sellers, of which 67% of the activity was facilitated by Coinbase. Coinbase believes that cryptocurrencies and stablecoins can provide global, programmable, 24/7 small-amount payment infrastructure for AI proxies.
