Coinbase CEO Brian Armstrong has pushed back on the idea that artificial intelligence will displace crypto, arguing that “agentic” AI—software systems that initiate actions—will increase demand for programmable, crypto-based payments. In a post on X, Armstrong framed AI agents as a new class of economic actors that will need rails and settlement mechanisms beyond traditional banking.
Armstrong pointed to Coinbase’s Base network, USDC, and its x402 payment protocol as key infrastructure for autonomous machine-to-machine payments. His comments follow mounting industry interest in using blockchain networks as the payments layer for AI agents, including coverage that agentic payment activity on Base surpassed 100 million transactions in June.
Key takeaways
- Armstrong argues AI agents will need programmable money, not conventional bank checkout rails, strengthening crypto’s role in finance.
- Coinbase’s “AiFi” framing ties Base (scalability), USDC (stable settlement), and x402 (automated payment flows) into a single payment stack.
- Chainalysis reported that x402-based agentic payments on Base crossed 100 million transactions in roughly nine months of tracked activity.
- Updated methodology and figures were requested, but Chainalysis had not responded by publication time, leaving some measurement details unconfirmed.
Armstrong’s “AI doesn’t replace crypto” message
Armstrong’s argument is essentially about incentives and infrastructure. Rather than treating AI as a competitor to blockchain, he claims AI’s “megatrend” effect will amplify demand for financial services that can be triggered automatically and executed reliably by software.
On X, Armstrong linked this to the concept of agentic finance, or AiFi—the idea that AI agents will participate in the digital economy by initiating transactions and accessing services without human intervention. In that world, he suggested, payments need to be programmable and accessible to autonomous systems, which he contrasted with traditional banking rails designed around accounts and manual authorization.
Coinbase’s AiFi stack: Base, x402 and USDC
Coinbase’s approach centers on three building blocks: Base as the underlying network, x402 as a payment protocol for autonomous software payments, and USDC as the dollar-pegged stablecoin used for settlement.
Base was launched in 2023 as an Ethereum layer-2 network aimed at making onchain applications faster and cheaper to use. Coinbase positioned Base as general-purpose blockchain infrastructure rather than a network specifically engineered for AI payments.
Two years later, Coinbase introduced x402, a payment protocol built around the HTTP “402 Payment Required” standard. The intent is to enable automated stablecoin payments between software applications—allowing agents and other autonomous systems to pay for digital resources like APIs or data without relying on traditional account-driven checkout flows.
USDC, launched in 2018 by Circle and the Coinbase-backed Centre Consortium, is one of the assets used for x402 payments. In the AiFi framing, USDC provides the stable value layer while x402 standardizes how software applications request payment and complete transfers.
Taken together, Base + x402 + USDC are designed to make it easier for autonomous systems to interact economically onchain—an architecture Armstrong appears to believe will be increasingly necessary as AI agents become more active in commerce, data access, and service provisioning.
What Chainalysis measured on Base
Beyond Coinbase’s vision, the debate has increasingly moved to onchain activity—especially whether “agentic payments” are showing up in measurable transaction patterns. In a June report, Chainalysis said agentic payments on Base using x402 surpassed 100 million transactions within roughly nine months of activity.
Chainalysis described its measurement approach as identifying x402-related payment flows onchain. It also noted that transactions worth at least $1 accounted for 95% of total value transferred, indicating that the majority of transferred economic value was not concentrated solely in very small transfers.
The analytics firm further reported behavioral differences between agentic participants and typical Base users: it said agentic payment wallets were generally newer, held more asset types, and maintained smaller balances on average than Base users in general.
Cointelegraph asked Chainalysis for updated x402 activity figures and more details about its tracking methodology, but the firm had not responded by the time of publication. That leaves a gap for readers who want the latest numbers and confirmation of how the methodology may evolve as activity scales.
Earnings calendar adds context for the timing
Armstrong’s push comes as Coinbase prepares to report second quarter earnings on Thursday. According to consensus data compiled by Yahoo Finance, analysts expect revenue of $1.29 billion and estimate sales to fall 13.8% year over year, with earnings per share projected to be flat.
While the earnings outlook is separate from the AiFi debate, it matters for investors because it frames how quickly infrastructure narratives may translate into business momentum. If activity around agentic payments continues to expand—especially in ways that attract developers and integrate stablecoin payments—Coinbase may view it as an additional growth lane on top of broader onchain adoption.
For now, the key question is whether agentic payment activity remains a measurable trend as adoption broadens beyond early x402 use cases. Readers should watch for fresh Chainalysis updates, more clarity on how “agentic” behavior is classified onchain, and whether Coinbase’s AiFi push leads to sustained developer and payment integrations on Base.
