X-Agent hackathon showcases early AI Agent economy

The ongoing X-Agent AI MCP Hackathon has received nearly 40 projects demonstrating autonomous agent behaviors. Notable entries include BountyProof, which validates GitHub bounty tasks; Abstain, which allows agents to refuse trades based on rules; and sumplus, which optimizes model selection based on cost and capability. These projects highlight the development of an agent economy centered on task acceptance, capital management, and service procurement.
