Stripe Integrates x402 Payments on Base
Fintech giant Stripe has reportedly integrated x402 payments on the Base network, signaling a convergence of mainstream payments and crypto infrastructure. Analysts note that the quiet adoption of the protocol by major tech firms highlights a key trend in the intersection of AI and crypto payments. The move is seen as a significant step for real-world adoption on the Ethereum L2.
- The x402 protocol is an open standard developed by Coinbase that activates the long-dormant HTTP 402 "Payment Required" status code, allowing for machine-to-machine micropayments. This enables use cases like AI agents autonomously paying for API access or data. - Stripe's history with crypto includes being one of the first major payment companies to support Bitcoin in 2014, a feature it later discontinued in 2018 due to high fees and volatility. The company re-entered the space by enabling USDC payouts in 2022 and reinstated crypto payments for U.S. businesses in late 2024. - Base, the Ethereum Layer 2 network developed by Coinbase, is built on the OP Stack and designed for low-cost, high-speed transactions, with an average transaction fee of about $0.01216. It does not have its own native token and instead uses bridged ETH for gas fees. - This integration allows developers to charge AI agents and bots directly in USDC on the Base network for services, with Stripe handling the conversion to fiat and depositing it into the merchant's account. - In 2025, stablecoin payment volume doubled to approximately $400 billion, with an estimated 60% being for business-to-business transactions. Stripe's stablecoin orchestration platform, Bridge, which it acquired, saw its transaction volume quadruple in the same year. - Stripe is also developing its own payments-focused blockchain called Tempo in partnership with Paradigm, indicating a deeper move into building foundational financial infrastructure. - The company processed $1.9 trillion in total payment volume in 2025, a 34% increase from the previous year, and recently had a tender offer valuing it at $159 billion.
