The emerging vision of an AI-driven "machine economy" gained concrete infrastructure this week, as the Solana Foundation and crypto bank Anchorage Digital separately unveiled tools enabling autonomous, machine-to-machine payments on blockchain rails.
Speaking at Consensus Miami 2026, Solana Foundation president Lily Liu emphasized that growing stablecoin adoption by major enterprises is both validating blockchain as global financial infrastructure and laying the groundwork for AI agents that transact independently. She cited recent integrations by Meta and Western Union that use Solana for stablecoin payments, as well as Visa's 2023 decision to build settlement capabilities on Solana after what Liu called an "extensive objective review" of networks. "Fast and cheap is a no-brainer for payments," Liu said, adding that deep liquidity and a broad ecosystem are equally critical for enterprises.
Liu argued that traditional payment systems—dependent on credit cards and interchange fees—make microtransactions economically impractical, whereas blockchain enables sub-dollar transactions and real-time payment streaming. "The vast majority of transactions that happen on the internet are actually of microtransaction value," she noted, asserting that blockchains are uniquely suited for "agentic commerce" where AI agents pay for services autonomously.
Simultaneously, Anchorage Digital launched its own agentic banking service, allowing AI systems to move funds across fiat and crypto rails without human intervention. CEO Nathan McCauley described the system as providing verifiable identities, spending limits, and audit controls for each AI agent, addressing compliance requirements for institutions. The rollout includes a partnership with Google Cloud, which provides an intelligence layer for agents to discover services, negotiate terms, and coordinate transactions in real time.
McCauley, also speaking at Consensus, predicted that agent-to-agent payments could become "a trillion-dollar industry." Other recent developments underscore this momentum: the Solana Foundation and Google Cloud launched a gateway letting AI agents pay for APIs with stablecoins on Solana; Coinbase introduced Agentic.market, where over 480,000 agents have already processed 165 million transactions using USDC; and Tether-backed Oobit released a Visa card funded directly from Tether's treasury for AI agent purchases. Liu concluded that the industry still underestimates blockchain's ultimate role, describing it as "financial rails first and foremost" and pointing toward a future of "internet capital markets" that open global capital formation to companies and sovereign entities.
