Coinbase CEO Brian Armstrong posted on April 16 that agentic commerce ‘isn’t priced in yet and that machine-to-machine payments will increase demand for the digital dollar beyond current estimates. He went further: ‘The agentic economy could be larger than the human economy. We’re building the infrastructure for both at Coinbase.’

One day earlier, Tron founder Justin Sun launched B.AI on the Tron network, a full-stack financial infrastructure for AI agents covering identity, payments, settlement, and coordination. At Paris Blockchain Week, Sun argued that AI agents will need ‘fast, reliable, global payment rails’ and that Tron’s stablecoin liquidity makes it the natural foundation for them.
AI is evolving from tools into autonomous economic entities.

The thesis is the same. The stacks are not.
Coinbase’s stack: x402, Base, USDC
Coinbase launched Agentic Wallets on February 11, built on its x402 protocol. x402 is an open standard that attaches stablecoin payments to standard HTTP web requests, turning every API call into a potential transaction. By the time Armstrong made his March 9 post declaring AI agents would soon outnumber humans in financial transactions, the protocol had already processed over 50 million machine-to-machine payments.
Very soon there are going to be more AI agents than humans making transactions.
They can’t open a bank account, but they can own a crypto wallet. Think about it.

The infrastructure runs on Base, Coinbase’s Ethereum L2, enabling fast wallet creation, gasless trading, and seamless micro-transactions. Integrations with Cloudflare, Circle, AWS, and Stripe let AI agents transact in USDC directly within existing cloud stacks.
Armstrong’s core point is structural: AI agents can’t meet KYC requirements to open bank accounts, but crypto wallets remove that barrier, making them the default payment rail for autonomous systems.
Tron’s counter: B.AI, 8004 identity, USDT liquidity
Sun’s response came 24 hours before Armstrong’s latest post. B.AI, launched on April 15, has two key components: the 8004 identity protocol, which gives AI agents on-chain identities tied to activity and reputation, and x402, the open payment standard developed by Coinbase.
Notably, TRON didn’t build its own payment system, it adopted Coinbase’s standard and focused on identity, betting payments will commoditize while reputation becomes the real moat.
Tron’s pitch rests on scale. The network processes over $22B in daily transaction volume, hosts $86B in circulating USDT, supports 375M user accounts, and has recorded 13B total transactions, as per data from Tron’s latest press release. Annual stablecoin transfer volume runs at approximately $7.9T. Tron is also a Gold Member of the Agentic AI Foundation, a Linux Foundation initiative that is building interoperable standards for agentic infrastructure.
Where Coinbase ties AI agents to USDC and Base, Tron ties them to USDT and its own settlement layer. The stablecoin allegiance maps the competitive line precisely.
The shared standard nobody controls
The detail that connects both plays is ERC-8004, the Ethereum Foundation’s proposed standard for AI agent identity. The Ethereum Foundation’s dAI team, led by Davide Crapis, released its 2026 roadmap positioning Ethereum as the ‘global decentralized settlement and coordination backbone for AI.’ Both ERC-8004 and x402 are cited as the neutral standards for agentic commerce.
We’re starting a new AI Team at the Ethereum Foundation (the dAI Team).
Our mission: make Ethereum the preferred settlement and coordination layer for AIs and the machine economy.The team will focus on two main areas:

This creates a three-way dynamic. Coinbase built x402. Tron adopted it. The Ethereum Foundation endorsed both as the foundation for the machine economy. The protocol layer is converging, while the settlement layer is fragmenting. Whichever chain captures the most agent activity wins.
Other entrants are stacking up. CZ predicted AI agents could execute millions of times more transactions than humans. Mastercard and Google co-developed Verifiable Intent to track AI-driven purchases. EigenCloud partnered with Google Cloud for verifiable agent infrastructure. The field is crowding fast.
The skeptic: agents are not ready for real money
Shaw Walters, founder of Eliza Labs and creator of ElizaOS, offered a different view at Token2049 in Singapore. He warned that cryptocurrency users should not trust AI agents with large sums. In his assessment, current agents function best as ‘interfaces for analytical tools’ and as a layer for collecting social data, not as autonomous capital managers.
Walters is not a bystander. Eliza Labs launched the auto.fun platform for creating and monetizing AI agents, and is testing an OTC platform managed by agents within pre-set limits. His skepticism is practical, not ideological: the infrastructure is outpacing the agents themselves.
— Eliza Foundation (@elizafdn) April 25, 2025
His concern points to a gap neither Armstrong nor Sun has addressed. The 50M transactions Coinbase has processed and the $22B daily volume Tron handles are real. Whether the AI agents using those systems are ready for unsupervised financial autonomy is a separate, unanswered question.
