AI agent projects are seeing a general rise today—it seems the market believes the x402 protocol is beneficial for AI agent projects. The lack of native payment infrastructure between crypto AI agents has been a major gap, but now x402 fills in this missing piece. This not only deepens the narrative of the 'autonomous trading economy' for crypto AI agents but also practically enables transactions between them. x402 addresses a key pain point for crypto AI agents, moving from analysis/simulation to autonomous execution (payment APIs, data, DeFi), reigniting last year's narrative of the 'AI agent economy.' This won't just reshape the business model of the internet but will also create unprecedented economic interaction models between humans and agents, as well as between agents themselves. x402 + ERC-8004 + AP2 (A2A framework) will drive the continuous growth of AI agent transaction volumes. In the long term, these transaction volumes could surpass current DeFi levels—perhaps in five years, everything will look completely different.
