What is the X402 protocol? In one sentence, it's the payment infrastructure for the AI economy, enabling machines to have autonomous payment capabilities. After integrating x402 with the OK wallet, AI can truly make payments on its own. This also means it finally has its own wallet address and settlement layer. Plus, early interactions might come with perks or airdrops—there's a chance for some big rewards. HTTP 402 is not just a status code; it could be the next gateway to the AI economy. Oh, and don’t forget: Xlayer has launched USDG with an annual yield of 10%. If you’ve got idle USDT, you can stake it to earn interest.
