An intense global competition is unfolding among technology and cryptocurrency giants aiming to establish the best infrastructure for AI-enabled commerce. Over the past three years, the proliferation of advanced protocols has dramatically enhanced efficiency by standardizing inter-agency communications and automating payment procedures. These technological strides are particularly refining the processes through which software agencies exchange data, facilitate payments, and integrate with various digital platforms.
How Are New Protocols Fueling Market Expansion?
Anthropic’s Model Context Protocol is a prime example of innovation, with monthly software development kit downloads reaching 97 million and its implementation spanning tens of thousands of public servers. In April 2025, Google’s decision to transfer its Agent-to-Agent protocol to the Linux Foundation created a buzz, rapidly being adopted by over 100 companies. Earlier, in January, Google revealed the Universal Commerce Protocol, designed to harmonize payment and shopping processes among agencies, garnering support from industry giants like Shopify, Walmart, and American Express.
In the cryptocurrency arena, Coinbase’s x402 protocol has facilitated over 100 million automatic stablecoin transactions through HTTP by late 2025. A Gartner report anticipates that by 2028, AI powered by autonomous agents will be integrated into one-third of enterprise-grade software applications. Deloitte forecasts the industry’s value reaching $8.5 billion by 2026, potentially rising to $35 billion by 2030.
Is Verification the Missing Puzzle in AI-Driven Commerce?
Despite the focus on facilitating agency communications and automating payments, a significant hurdle remains in ensuring task completion verification. The assurance layer—a vital component to validate service delivery prior to payment release—is inadequately addressed.
A proposed Ethereum standard, ERC-8183, put forth in February 2026, proposes a job-based transaction model securing funds in a smart contract. The service provider submits work, which a third-party evaluator then reviews to approve or deny task fulfillment, thereby providing both human and software agencies with programmable assurance.
How Clear is the Line Between Authorization and Verification?
Big names like Google and Mastercard focus on ensuring secure payment authorization with new protocols based on cryptographic approvals. Mastercard’s Verifiable Intent initiative, for instance, enhances user capability to securely track purchase authorizations. Nonetheless, the actual completion of promised services remains unverified by these systems.
The ERC-8183 draft stipulates an evaluation step before any payment goes through, accommodating various evaluators like clients or decentralized networks. Meanwhile, within the Ethereum landscape, the ERC-8004 proposal aims to create a trust and reputation mechanism for agents and their partners.
Security evaluations raise alarms about rogue evaluators who might unjustly approve or reject payments, notably in high-stakes deals, prompting calls for additional protections. Concerns have also emerged regarding a single evaluator’s influence in complex, multi-party networks.
The progress of agency-driven commerce highlights the emerging gap between payment authorizations and real verification of service delivery. The influence of crypto-driven smart contracts versus tech giant’s authorization frameworks will be pivotal as the broader ecosystem evolves.
“Ensuring true verification and security in transactions remains the linchpin for future commerce systems,” commented a tech industry expert.
