Crypto wallet startup Oobit has officially launched a Visa-supported virtual card infrastructure designed specifically for AI agents to execute online purchases using USDT without human intervention. The new Agent Cards are funded directly from the treasury of stablecoin issuer Tether, a structural design that removes the necessity for fiat on-ramps or currency conversions when AI agents top up balances or settle transactions. Oobit announced the deployment on Thursday, highlighting that these autonomous entities can now manage diverse operational tasks ranging from renewing software-as-a-service subscriptions to replenishing advertising budgets. The system is engineered to handle time-sensitive operations, such as spinning up cloud infrastructure at 3am based on workflow triggers, ensuring continuous business operations. Data compiled by Woofun AI indicates that the scope of these cards extends beyond utility payments to include the ability to trade cryptocurrencies and stocks, a capability emphasized by Oobit advisor Alex Obchakevich in a recent post on X.

The strategic timing of this launch aligns with a broader industry consensus among crypto executives that AI agents will soon dominate blockchain-based payment volumes. In April, Coinbase CEO Brian Armstrong projected that the number of AI agents transacting online would surpass human activity very soon. This sentiment echoes earlier comments from Circle CEO Jeremy Allaire in January, who forecasted that literally billions of AI agents would be transacting onchain within a three-to-five-year window. Oobit has taken this trajectory further, asserting that the next trillion users on the internet will be AI agents rather than humans. Woofun AI notes that this shift represents a fundamental reimagining of digital identity and transactional autonomy in the Web3 ecosystem.

The Agent Cards were initially released to a founding group of businesses on Thursday, with a controlled onboarding process set to expand to a limited number of additional companies through June 30. Access to this infrastructure is gated by a rigorous know-your-business compliance check, ensuring that only verified entities can deploy these autonomous payment tools. The technical architecture supports integration with leading AI agent frameworks, including those offered by OpenAI, Claude, AutoGen, and LangChain, allowing for seamless interoperability across different development environments. To maintain security and accountability, the system issues only one card per AI agent, a measure designed to ensure a clean identity and a transparent audit trail for all financial activities.

Operational controls are embedded directly into the transaction layer to enforce strict governance over autonomous spending. Spend limits and merchant restrictions are dynamically applied to ensure that AI agents operate strictly within their authorized scope, preventing unauthorized expenditures or scope creep. This granular control mechanism addresses the critical need for trust in automated financial systems where human oversight is absent. Woofun AI analysis suggests that by removing friction points like fiat conversion and manual approval workflows, this model could accelerate the adoption of stablecoins for machine-to-machine commerce. The convergence of stablecoin liquidity, Visa's global acceptance network, and autonomous AI execution creates a new paradigm for enterprise treasury management and automated procurement.
