The web infrastructure giant is borrowing from Ethereum's original scaling playbook to handle millions of AI-driven micropayments per second
Cloudflare, the company that routes roughly 20% of all global web traffic, just launched a payments product that could quietly reshape how machines pay each other on the internet. And the scaling architecture behind it? Borrowed straight from Ethereum’s original sharding blueprint.
Will Papper, who joined Cloudflare as Director of Product in July 2026, is leading the company’s push into stablecoin micropayments. His thesis is straightforward: the internet needs a payment layer that can handle 5 to 50 million transactions per second, and no existing blockchain comes close to delivering that on its own.
The Monetization Gateway and x402 #
Cloudflare launched its Monetization Gateway on July 1, 2026, giving sellers the ability to charge for web resources using USDC stablecoin payments settled on Base and Polygon networks. The product is built around x402, a revived version of HTTP’s long-dormant 402 status code, now optimized for stablecoin transactions with near-instant finality and negligible fees.
The target customer isn’t a person buying coffee. It’s an AI agent making sub-cent payments millions of times per second to access APIs, data feeds, or computational resources across the web. Traditional payment rails like credit cards charge minimum fees that make transactions below a few cents economically absurd. Stablecoins on fast L2 networks don’t have that problem.
Settlements through the gateway happen on-chain in seconds, which matters when you’re talking about autonomous software making purchasing decisions without human intervention.

Why Ethereum’s sharding design matters here #
Papper has pointed to Ethereum’s original sharding design as the architectural model for scaling Cloudflare’s stablecoin payment infrastructure. Sharding, in its simplest form, is the idea of splitting a database into parallel pieces that can each process work independently. Ethereum co-founder Vitalik Buterin proposed sharding years ago as the path to massive throughput, though the network ultimately pivoted toward a rollup-centric roadmap instead.
Cloudflare’s interest in this design makes sense given the math involved. If AI agents are generating millions of payment requests per second across the company’s network, no single blockchain or single-server architecture can absorb that load. Papper’s argument is that the throughput demands of machine-to-machine commerce will eventually exceed what all existing blockchains can handle combined.
The AI agent economy takes shape #
Cloudflare is uniquely positioned to capture this shift. The company already sits between clients and servers for a massive chunk of the internet. Adding a payment layer at that chokepoint turns existing infrastructure into a toll road, one where the tolls are fractions of a cent and the drivers are algorithms.
For the stablecoin market specifically, Cloudflare’s entry validates a use case that goes well beyond the typical remittance and trading narratives. USDC issuer Circle stands to benefit directly from increased on-chain volume flowing through Base and Polygon, and the selection of those two networks over alternatives like Solana or Arbitrum signals where Cloudflare sees the best combination of speed, cost, and reliability for payment workloads.
