Most of the attention around AI payments has gone to traditional payment giants such as Visa, Mastercard and Stripe, or to AI platforms like OpenAI and Google. The article argues that the more consequential development may be happening elsewhere: Coinbase has quietly become a major real-world operator in agent payments.
It cites disclosures from Coinbase’s quarterly earnings calls in 2026 showing that more than 90% of on-chain agent transactions took place on Base, 99% of agent business transactions were settled in USDC, and more than 97% of on-chain agent transactions used the x402 protocol. Base, according to the same figures, accounted for 62% of stablecoin transaction volume across the industry.
Coinbase’s bet is not a payment protocol alone, but a wallet for agents
On Feb. 11, 2026, Coinbase introduced Agentic Wallets through its developer platform, positioning the product as wallet infrastructure built for AI agents.
Before that, the article says, payment infrastructure for agents largely fell into two buckets: APIs for developers or payment entry points for users. The agent itself did not really have an account of its own. If it needed to spend money, it had to rely on a human account or operate indirectly through a platform interface.
Agentic Wallets changes that model by turning the agent into an entity that can hold assets. An agent can have its own wallet address and, within preset permissions and risk controls, hold funds, initiate transfers, execute trades and collect revenue without using a human account as the middle layer.
The stack is made up of several parts. At the base is Agent Kit, Coinbase’s open-source toolkit launched in 2025 to let developers integrate wallet functionality into any agent system. In the middle is x402, a machine-to-machine payments standard built around the HTTP 402 status code that has already processed more than 50 million transactions. On top of that sit non-custodial wallets and security tools that are deeply integrated with the Coinbase Developer Platform.
Together, those parts form what the article describes as a full financial account for an agent.
Why an agent would need its own wallet
The piece spends time on a basic question: if an agent is buying something on behalf of a person, why not just use that person’s credit card?
Its answer is tied to the nature of agent payments. Many of these transactions are machine-to-machine, high-frequency and tiny in size. One example in the article is an agent calling another agent’s API and paying one-thousandth of a cent for a data query.
Using a human credit card for that type of payment creates several problems. Fees are one. Card payments usually combine a percentage fee with a minimum charge, and at one-thousandth of a cent the fee can exceed the principal by several orders of magnitude. Authorization is another. Human card payments typically require cardholder approval, which does not work if an agent needs to make repeated micropayments automatically. The third issue is attribution. A credit card is tied to a person’s identity, while a payment between one agent and another may need to be traced back clearly to a specific agent, platform or user.
A dedicated wallet for the agent addresses those constraints. Funds can be held in stablecoins, transfer costs are low, spending permissions can be controlled through code-level policies, and the wallet address itself serves as a distinct on-chain identity. That makes attribution and traceability clearer.
The article uses that logic to explain why 99% of agent business transactions in Coinbase’s disclosed data were settled in USDC. The point is not framed as USDC being universally better than cards, but as stablecoins plus on-chain wallets being a closer technical match for agent-to-agent payments.
A closed loop built around chain, wallet, protocol and assets
The article says Coinbase’s position in agent payments comes from more than a single product. It has Base, an internally operated Layer 2 network. It has Agentic Wallets for agents. It has x402 as a machine-to-machine payment protocol. It also has native wrapped assets such as cbBTC and cbETH.
Those four elements — wallet, chain, protocol and assets — all sit inside Coinbase’s own ecosystem. In practice, that means an agent can hold funds, initiate payments and complete settlement without leaving the company’s stack.
That structure gives Coinbase a different position from several other players named in the article. Visa has a payment network but not a wallet for agents. Stripe has merchant infrastructure but not its own chain. Circle has a stablecoin but not its own network layer. Coinbase, the article says, is one of the few companies with control over several critical layers of the agent payment flow at once.
The same setup also comes with tradeoffs. The advantage is a more complete user experience with less friction between systems. The risk is that if one link fails, the wider system can be affected. The article points to Coinbase’s net loss of $359 million in the second quarter of 2026 as a reminder that maintaining this structure is not cheap.
How the company got into this position
The piece describes Coinbase’s rise in agent payments as partly accidental. Base was not originally built specifically for agent payments; it was launched to expand Coinbase’s on-chain ecosystem. x402 was first proposed as an internet-native machine payment standard, not as an agent-only protocol. Agentic Wallets did not arrive until February 2026.
But when the agent economy started growing quickly, Coinbase found that it already had positions across several key layers. Base happened to be one of the lower-cost environments for high-frequency, low-value transactions. x402 happened to fit machine-to-machine payments. Agentic Wallets happened to fill the gap around giving agents their own financial identity.
The article ties those overlaps to Coinbase’s multi-year investment in on-chain infrastructure. Its argument is that Coinbase did not start building when agent payments took off. It had already been putting wallets, chain infrastructure and protocol components in place before the agent economy was fully formed.
What that says about the AI payments race
The article closes by saying the AI payments narrative is still centered on three questions: which protocol becomes the standard, which payment rail wins, and how card payments and stablecoins might converge.
Coinbase’s data offers another angle. While the market is still debating standards and rails, agent payments are already happening at scale, and the article says much of that activity is running on Coinbase’s infrastructure.
Its conclusion is not that Coinbase is guaranteed to be the final winner. The narrower point is that adoption may depend less on having the most elegant standard and more on having usable infrastructure ready when demand arrives. On that measure, the article says, Coinbase has already taken an early lead.
