CZ said: "AI agents will make 1 million times more payments than humans, and they will use crypto." Most people will treat this as hype. The technical argument behind it is more specific. AI agents have a payment problem that human payment systems can't solve. They can't hold credit cards. They can't use bank transfers. They can't wait for human approval to execute a transaction. And they can't sit on a pile of gas tokens just to pay fees on every micro-payment. Traditional payment rails require a human at some point in the loop. AI agents don't have one. This is why BNB Chain's latest upgrade matters more than it looks. They upgraded the $U stablecoin to support EIP-3009: "transfer with authorization." An AI agent can approve a payment offchain using a cryptographic signature and execute it onchain. No native gas tokens required. No human approval. No gas token custody. Just: authorize, execute. At micropayment scale, across millions of agents transacting simultaneously, that's the infrastructure difference between a viable agent economy and one that breaks under its own friction. CZ has called crypto "the native currency for autonomous systems" since Davos. This upgrade is a concrete step toward making that true on BNB Chain.
