From Shared Wallets to Spending Interfaces: A Systems Critique of FluxA From Shared Wallets to Spending Interfaces: A Systems Critique of FluxA ad #FluxA #FluxAWallet #FluxAAgentCard #AgenticPayments #AIAgents The old workflow for agentic payments is awkward: a human keeps the card, the API key, the checkout session, and the approval habit, then asks an AI agent to act “autonomously” while still paging the human whenever money enters the loop. The newer workflow I want is different: the agent gets a defined spending interface, the operator gets policy boundaries, and the merchant gets a payment event that looks intentional instead of improvised. That is the lens I used to evaluate FluxA. I am not treating it as “just another crypto wallet” or “just another AI tool.” The interesting design question is narrower and more operational: can FluxA make spending by AI agents feel less like credential sharing and more like a controlled system primitive?…
