Delegating the fund management of a DAO to an AI agent essentially means outsourcing "trust" to a piece of code. If it tells you that it has compliant expenditures of $50,000, under a black box model, you have little choice but to choose to believe it. However, once the scale of funds increases, this "belief" can turn into systemic risk: Did it deduct an extra fee? Has the record been tampered with? No one can provide a definitive answer. I believe that the x402b launched by @brevis_zk and @pieverse_io is crucial. By synchronously generating zero-knowledge proof receipts when paying with pieUSD, it upgrades "I have done this" to "I can be proven to have done this," without sacrificing privacy. @brevis_zkAI can automatically generate auditable vouchers that can be used for reimbursement and tax purposes, giving on-chain actions traceability. As AI agents increasingly participate directly in the flow of funds, what DAOs need is not smarter agents, but more reliable constraint mechanisms. Verifiable receipts are becoming the minimum requirement in the AI financial era, rather than a bonus.
