What makes the x402 protocol special? The core points are actually five. First is the open standard, which means anyone can participate and build. Second, it is natively HTTP, directly based on network protocols, making integration seamless. The third key point is that it is chain and Token agnostic; the more compatible assets, the better. The fourth and most important is the principle of minimal trust — third parties cannot bypass user consent to misuse funds, which is the bottom line. Lastly, it truly enhances user convenience: users don't have to worry about gas fees on either end of payments, as the protocol facilitator handles it uniformly, greatly improving the user experience.
