The world of finance is on the verge of a fundamental shift. We are accustomed to every payment—from selecting a product to confirming a purchase—requiring human involvement. But with the advent of AI agents, this model is collapsing. This is not just about automation, but about transferring the right to make decisions to autonomous programs.

What Are Agentic Payments?

AI agent payments (agentic payments) are transactions initiated and executed by an autonomous system without direct user participation. Unlike a standard auto-payment that triggers based on a rigid rule (e.g., deducting an amount each month), an AI agent acts contextually: it assesses the situation, compares options, and makes decisions based on set constraints.

The level of autonomy varies. In passive mode, the system only marks an invoice for payment and awaits confirmation. In intermediate mode, it acts independently but escalates large transactions for manual review. In fully autonomous mode, the assistant independently tracks expenses, compares prices, and pays according to predefined rules.

Architecture of the New Payment Layer

The infrastructure for agentic payments is being built by three key camps: traditional payment networks, tech giants, and crypto projects. Visa and Mastercard have already introduced their solutions—Intelligent Commerce and Agent Pay, respectively. They use digital tokens with embedded conditions that verify the agent's authority before executing a transaction.

On the other end are blockchain solutions. Here, the key player is the x402 protocol, based on the long-forgotten HTTP code "402 Payment Required." In May 2025, Coinbase and Cloudflare turned it into a working settlement mechanism. When an AI agent requests paid content, the server instantly returns the price and wallet address. The buyer's system automatically sends the funds, and the data becomes available in fractions of a second.

Over the past year, more than 35 million transactions worth over $10 million have passed through x402 on the Solana network. Fees amount to fractions of a cent, making the protocol ideal for microtransactions that are economically unviable for card networks.

Blockchain vs. Traditional Finance: The Battle for Transparency

The key difference between the two approaches lies in transparency. On-chain settlements are public by default: every transaction remains permanently in an open ledger. Analytical platforms like Arkham or Chainalysis can reconstruct an agent's operational profile by analyzing its wallet and connections.

In the case of Mastercard or Visa, data is stored in closed databases accessible only to the issuer and servicing banks. It is hidden from the public. As the number of AI agent wallets grows, this difference in transparency will become critical for both regulators and the market.

Barriers and Prospects

Despite obvious advantages, blockchain settlements face serious barriers. Many merchants are wary of digital assets, and the regulatory status of stablecoin payments varies by country. Additionally, card networks retain an advantage in fraud protection and dispute mechanisms.

A likely scenario is the coexistence of two systems. Traditional networks will dominate everyday purchases, while blockchain will carve out a niche in microtransactions and settlements between autonomous systems. The question of liability when an agent errs remains open—regulators have yet to determine who is responsible if the system exceeds its authority or misinterprets instructions.

My view: We are witnessing the birth of a new financial layer where algorithms, not people, will become the primary consumers of payment services. For the crypto industry, this is a window of opportunity—blockchain was originally designed for machine interactions. But to capture the mass market, security and regulatory issues, which remain the main restraining factors, will need to be resolved.
