The agentic commerce industry has spent months debating which payment protocol will dominate — x402, Google’s Universal Checkout Protocol, or Mastercard’s Agent Payments for Merchants. But according to Paymentology CTO Tim Joslyn, the industry is asking the wrong question.
“Probably 99% of the issuer processing systems out in the world could process an agentic payment,” Joslyn told PYMNTS in July 2026. “The issue becomes whether you’ve recognized the transaction as an agent payment, and whether you’ve put the right identity and trust frameworks around it.”
If Joslyn is correct, the payment rails themselves — cards, ACH, real-time payments, stablecoins — are effectively commoditized for agent transactions. The competitive battleground has shifted up the stack to Layer 2 of the payments architecture: identity, authorization, and AI-native fraud controls.
The IMF’s Three-Layer Map
The International Monetary Fund’s April 2026 working paper provides a useful framework for this shift. Researchers Davidovic and Tourpe describe three layers: Intent and Orchestration at the top, where consumers delegate authority to agents; Control and Authorization in the middle, where trust decisions happen; and Settlement at the bottom, where money actually moves.
While the industry focuses on Layer 3 settlement, the actual competition is occurring at Layer 2. In the West, the landscape is increasingly crowded. Visa launched Agent Score and an Agentic Directory. Mastercard built AP4M Credentialing. Stripe developed Shared Payment Tokens with scoped permissions. The FIDO Alliance is working on passkey-based agent authentication. Each entity is building a proprietary trust layer, and none are interoperable.
“The rails work,” Joslyn said. “What doesn’t exist yet is a common framework for determining whether an AI agent is trusted to spend money on someone’s behalf.”
This fragmentation creates a significant tax on agentic commerce. Merchants must navigate multiple proprietary identity and authorization systems, each with different credential formats, fraud models, and dispute resolution mechanisms. Independent analysis confirms this structural friction.
“The future of agent-led buying and selling will depend on industrywide solutions for trust, identity, and payments,” wrote Forrester analyst Emily Pfeiffer in May 2026.
Pfeiffer’s assessment highlights the gap between the market’s need for industrywide standards and the vendor-specific solutions currently being delivered by Western protocol builders.
The China Contrast
China has taken a different approach. Alipay’s ACT Protocol, launched in January 2026, serves as China’s first open agent commerce trust standard. It integrates identity verification, consumer controls via AI Wallet, and merchant authentication into a single framework already connected to 30 million merchant devices. The contrast is structural: where the West fragments trust infrastructure across competing vendors, China is standardizing it.
The Trust Ceiling
The stakes are visible in consumer behavior. A Product.ai survey from April 2026 found that only 14% of consumers who used AI for product research trusted AI recommendations without verification. Furthermore, 42% stated they would not trust AI to execute purchases over $25. This trust gap is not a protocol problem; it is an identity and authorization problem that no settlement layer can solve.
The crypto-native agentic commerce stack faces a similar trust deficit. While x402, the most active protocol on Base, has processed over 200 million transactions, the underlying activity is questionable. Artemis Analytics found in February 2026 that roughly half of these transactions are artificial, characterized by self-dealing and wash trading. CoinDesk reported in March 2026 that the real daily volume is approximately $28,000. The protocol functions, but the trust layer around it does not.
“We need to move from ‘can the payment go through’ to ‘should this payment go through,’” Joslyn said. “That’s a fundamentally different problem, and it requires a fundamentally different infrastructure.”
The industry now faces a choice: will Western protocol builders converge on shared trust standards before China’s integrated model becomes the global default? The payment rails are ready, but the trust layer remains the primary obstacle.
