Imagine a near-future scenario: an AI agent you dispatched discovers an arbitrage opportunity on-chain or needs to pay a data access fee. In the past, it had to stop to request your private key signature, or you needed to pre-deposit a large amount of funds into a highly risky hot wallet. But now, with the Q402 protocol launched by QuackAI, all of this has changed.
The Q402 provides a unified payment signature execution and governance layer for these digital beings. It's like giving the AI Agent an "enterprise credit card" with automatic risk control features. As the owner, you only need to preset governance strategies—such as "single transaction must not exceed 50 USDT" or "only interact with specific whitelisted contracts." When the AI needs to make a payment, the Q402 protocol automatically checks the strategy and generates a signature in real-time to complete the payment. This "signature as payment" process truly enables AI agents to operate independently in the Web3 world while being strictly constrained within your governance boundaries. This is not simple automation; it is a perfect match between digital labor and execution power, allowing your assets to create value on-chain 24/7 under secure conditions.
