Coinbase CEO Brian Armstrong this week laid out a vision where AI agents become a major engine for cryptocurrency adoption. Speaking about the intersection of artificial intelligence and blockchain, Armstrong pointed to the company's Layer-2 network Base as proof that the trend is already underway — Base has processed over 100 million AI-related payments.
Armstrong's pitch for 'agentic finance'
Armstrong identified three core components that he says will define what he calls 'agentic finance': Base, USDC, and the x402 protocol. The idea is that AI agents — automated programs that can transact, negotiate, and manage assets — need a native financial layer that's programmable, fast, and cheap. That's where crypto comes in.
“AI agents will expand cryptocurrency adoption,” Armstrong said, framing the shift as a natural evolution of both technologies. He didn't offer a timeline for mass adoption, but the numbers from Base suggest the infrastructure is already handling real volume.
Base hits 100 million AI payments
Base, Coinbase's Ethereum Layer-2, has now processed over 100 million payments initiated by AI agents. That's a milestone that puts concrete data behind what has mostly been theoretical talk in the industry. The network launched in 2023 and has steadily grown its transaction count, but the AI-payment figure is a new metric the company is highlighting.
The 100 million figure covers everything from microtransactions for API calls to automated settlement between bots. It's not just test traffic — these are live payments, many of them using USDC, the stablecoin issued by Circle that Coinbase helped popularize.
The x402 protocol and USDC's role
Armstrong specifically called out x402 as a key piece of the agentic finance stack. The protocol, which Coinbase has been developing, is designed to let AI agents make payments without human intervention — think of it as a standard for machine-to-machine transactions. USDC provides the stable value layer, so agents aren't exposed to crypto volatility when they're just trying to pay for compute or data.
Together, Base, USDC, and x402 form a trio that Armstrong argues is ready for prime time. “These are the rails,” he said, “for the next wave of autonomous commerce.”
The timing isn't accidental. AI agents are proliferating fast — from trading bots to content generators to supply-chain managers — and most of them still rely on traditional payment rails that weren't built for machines. Credit cards and bank transfers assume a human is in the loop. Crypto, by contrast, lets an agent hold a wallet, sign a transaction, and settle in seconds.
Coinbase is betting that being the default payment layer for AI will bring millions of new users — or rather, millions of new agents — onto its platform. Whether that translates into revenue for the exchange or just more on-chain activity remains an open question. But with 100 million payments already logged, the experiment is past the proof-of-concept stage.
