#稳定币应用与发展 After reading this article about the AI agent economy, I have to admit—these writers have hit on a real issue.

On the surface, protocols like x402, ACP, and AP2 are all solving the problem of "how machines spend money," but at their core, they are building a new trust system. This reminds me of the essence of copy trading—you’re not trading with an account, but betting on a person’s long-term ability and risk awareness.

The key insight here is: stablecoin transactions settle in seconds and are irreversible, which is completely opposite to traditional finance dispute resolution mechanisms. Card networks can give you refund rights because they maintain a protection system through interchange fees. But the agent economy demands efficiency and low costs, which means trust must be established upfront.

Identity verification, fraud detection, and dispute resolution—these three areas are opportunities for startups. Like copy trading, this is a layered problem. You can’t assign the same risk limit to every novice; a reputation scoring system is needed. An agent’s historical performance, trading patterns, and whether they’ve been "scammed" before should all be verifiable.

I believe the most immediate maturity will come from the dispute resolution layer. Charging a 0.5% fee as insurance, comparable to the 1.5%-3% of card networks, makes sense logically. But the cold start for the identity layer might be the real bottleneck—without enough nodes participating in verification, the entire system’s credibility is compromised.

This aligns with the logic of choosing copy trading counterparts: you should look not at single gains, but at the person’s history, risk management approach, and performance under pressure. The agent economy is just about automating and on-chain-ifying this logic. Interestingly, this means stablecoin applications are no longer just payment tools but part of the trust infrastructure. Worth paying attention to.
