Base MCP: The Next Stop, the “Application Layer” Battlefield for Agent Payments | Bee Network
Players familiar with Base know that the current main narrative on the Base chain is AI, so this update comes as no surprise. Some players even anticipate new gameplay emerging on Base, similar to the AI meme coin $SHIT previously on Ethereum, where they could directly use chat through Base MCP to let Agents participate in on-chain new token launches.
However, if we step back from the perspective of an on-chain degen and view this through the lens of Agent-to-Agent payment competition, we might find a new answer to why AI has become Base’s main narrative.
The Rapidly Evolving Agent Payment LandscapeLet’s rewind to September 2024. At that time, if you wanted an AI Agent to make a payment for a fee, humans essentially had only one option: using browser automation tools (like Playwright, Selenium, or other headless browsers) to have the AI Agent simulate human actions and complete the checkout process on a webpage.
Because this required providing payment credentials (such as full credit/debit card numbers, CVV, expiration dates) to the AI Agent, this singular option was inherently insecure.
Fast forward to May 2025, Coinbase launched x402, providing AI Agents with a crypto wallet and solving this problem in a crypto-native way. But Coinbase wasn’t the only one to recognize this potential market, nor is the crypto-native approach the only solution. In 2025, Google introduced AP2, allowing users to delegate spending authorization to Agents. Visa expanded its existing card payment channels with Visa Intelligent Commerce, which doesn’t give Agents sensitive credit card numbers or CVVs but instead provides specific, restricted tokens for Agents to complete payments.
Today, x402 has processed 176 million transactions from AI Agents, with a total transaction volume exceeding $70 million. While this amount might seem modest, neither Coinbase nor traditional giants are taking this emerging payment competition lightly:
– On January 22, 2026, Capital One, the sixth-largest bank in the US with $470 billion in assets, $330 billion in deposits, and the third-largest credit card issuer in the country, announced the acquisition of Brex for $5.15 billion to enhance its AI payment capabilities.
– In March 2026, Mastercard acquired stablecoin infrastructure company BVNK for $1.8 billion.
– In February 2025, Stripe acquired stablecoin payment platform Bridge for $1.1 billion.
Although they haven’t explicitly stated it, acquiring stablecoin-related companies is a strategic move to prepare for the upcoming era of Agent payments. And stablecoins are indeed crucial for Agent payments.
Why Are Stablecoins Important for Agent Payments?According to data from Keyrock, the median transaction amount for Agent transactions processed on x402 to date falls between $0.01 and $0.10, with 76% of transactions being under $0.30.
$0.30. This is the most common fixed per-transaction fee in the US and many mainstream markets. This fee acts as a barrier, making micropayments under $1 highly uneconomical. For example, for a $0.03 API call, a $0.30 fee represents a 10x cost multiplier. If an Agent uses a credit card, the cumulative costs would become prohibitively high.
Blockchain solves this problem effectively. On Base, the transaction settlement cost is $0.0001. With this massive advantage, stablecoins have almost naturally won the competition against traditional payment giants in the Agent payment space.
Of the 176 million Agent transactions already processed by x402, 98.6% were settled in USDC. Given the close relationship between Coinbase and Circle, it’s fair to say Coinbase is a major winner on the settlement layer as well.
But the settlement layer is just one layer of Agent payments. In the race to solve Agent payments natively through crypto, Coinbase has a competitor—Stripe.
The Challenge from StripeIn March of this year, Stripe launched its Agent payment protocol, MPP. This brings Stripe’s architectural footprint in the Agent payment space nearly on par with Coinbase’s.
– On the settlement layer: Coinbase has Base, Stripe has Tempo
– On the wallet layer: Coinbase has Agent Wallet, Stripe has Privy
– On the routing layer: Coinbase has built-in routing infrastructure, Stripe has Bridge, acquired for $1.1 billion
– On the payment protocol layer: Coinbase has x402, Stripe has MPP
Now, let’s return to the Base MCP mentioned at the beginning of this article. Since both competitors now possess these four layers of infrastructure, the next battleground is naturally the application layer.
This is the core reason why AI has become Base’s main narrative—Base needs to ensure that AI (at least AI within the cryptocurrency space) happens on Base. This isn’t actually about catering to degens on the Base chain; rather, it’s about broadening the use cases for Agent payments, enabling more Agents to facilitate more transactions for more applications, thereby securing Base’s leading position in the Agent payment track.
Once a dominant scale advantage is established, when Agent payments eventually enter the commercial domain, Coinbase will be in an even better position to win big.
Viewing the launch of Base MCP from this perspective reveals that it is merely a small step within Coinbase’s vast ambition.
