The x402 Foundation was established on April 2nd. Personally, I think its current stage is similar to when Ethereum launched in 2015. The goal was to be "a world computer hosting decentralized apps." Everyone thought the vision was great, but nobody knew what it could actually do. Then came ICOs, DeFi, NFTs, RWA…
To be frank, the first wave of PMF (Productivity, Finish, and Factor) for the X402 might appear next year?
