Circle and Stripe are joining forces to build an on-chain payment infrastructure specifically designed for artificial intelligence agents, a trend that may reshape the very nature of blockchain transactions. Circle's launch of programmable wallets allows developers to embed USDC transactions directly into AI code, enabling AI agents to autonomously complete API calls, computing power procurement, or data purchases without human intervention, realizing the entire process of revenue, expenditure, and settlement on-chain. Meanwhile, Stripe has relaunched its crypto payment function, supporting users to complete online payments and bill settlements using USDC via the Solana, Ethereum, and Polygon networks, completely bypassing traditional credit card systems. Although the two industry giants are taking different paths, they are both pointing towards the same future: an automated economy between machines.
Stablecoins have become the preferred choice due to their structural advantages. AI agents cannot open bank accounts, while blockchain addresses naturally combine identity and payment functions, eliminating the need for compliance audits or cumbersome registration. Furthermore, traditional payment systems are too expensive for sub-cent transactions; a five-cent API request would be uneconomical if processed through a credit card network. In contrast, stablecoin transaction costs based on Layer 2 networks such as Base or Solana are less than one cent, making high-frequency, small-amount machine-to-machine settlements possible.
Smart contracts further expand the flexibility of payments. Funds can be locked in escrow, automatically released only after the AI completes a specified task—for example, paying $1 after analyzing data, and paying $0.50 after submitting a report. This "conditional trigger payment" shifts transactions from human decision-making to programmatic execution.
Data shows that payment transaction volume on the Solana network has surged by 755%, driven by the rise of the AI agent-driven on-chain economy. Circle CEO Jeremy Allaire predicts that by 2026, a significant proportion of total on-chain transaction volume will originate from automated settlements between non-human entities, rather than buying and selling activities by human users. This means that on-chain transaction volume and stablecoin flow data, which were previously regarded as indicators of "market activity," will increasingly reflect service transactions between software systems in the future. An increase in transaction volume does not necessarily represent user growth, but may simply be AI agents running continuously.
This shift will profoundly impact our understanding of the blockchain economy: when machines become the main participants, traditional analysis models based on human behavior will face reconstruction. The on-chain ecosystem is no longer just a market for "people," but is evolving into a new type of economic network driven by code and operating automatically.
