# Cloudflare and Arc — two different stories that get conflated

Updated 2026-09-02. Cloudflare's Web3 Gateway has no confirmed Arc listing. Its real, separate stablecoin story is x402 agentic payments with USDC — not Arc-specific.

> Not confirmed: Cloudflare's Web3 Gateway product — its RPC-style access point for blockchain data — has no Arc listing in its public documentation as of 2 September 2026; its documented chain support centers on Ethereum and IPFS. Separately confirmed, and genuinely significant, but not the same thing: Cloudflare has built out real stablecoin infrastructure in 2026 around the x402 payment protocol, giving AI agents stablecoin wallets to pay for API access — using USDC broadly, not Arc the blockchain specifically. This page keeps those two stories apart.

## What Cloudflare's Web3 Gateway is

Cloudflare's Web3 Gateway is a distributed-web infrastructure product offering gateway access to Ethereum and IPFS — letting developers read and write to those networks through Cloudflare's edge network rather than running their own node. Its public documentation, including the API-methods reference and "about" pages, names Ethereum-compatible EVM chains and IPFS as what it supports; no page in that documentation set names Arc, and no Circle or Cloudflare announcement pairing the two was found in the sources checked for this page.

## Is Arc supported? Not confirmed

Since Arc is EVM-compatible, it's technically true that RPC-style access to it could, in principle, be built the way Cloudflare's Ethereum Gateway works for Ethereum — but that is a statement about technical feasibility, not a confirmed product listing. As of 2 September 2026, no Arc entry exists in Cloudflare's Web3 Gateway documentation, and this directory found no announcement, blog post, or changelog entry from either company naming Arc in connection with Cloudflare's gateway product.

## A separate, real Cloudflare-stablecoin story: x402

Where Cloudflare's stablecoin story actually is substantial in 2026 is a different product line entirely: x402, an open payment protocol Cloudflare has built out jointly with Coinbase (the two launched the x402 Foundation together) to let AI agents pay for API access using stablecoins autonomously, without human-in-the-loop checkout flows. Reporting through mid-2026 — InfoQ, The Defiant, Coindesk — describes Cloudflare embedding x402 agent-payment capability at the edge, including giving agents their own stablecoin wallets, and Cloudflare and AWS have both been reported building x402 support into their infrastructure. This is real, dated, and substantive. It uses USDC as the settlement asset in the reporting reviewed — a Circle product — but nothing in that coverage names Arc as the settlement or execution chain for x402 transactions.

## Why the two stories get conflated

Both involve Cloudflare, both involve stablecoins, and both involve Circle's USDC by name — which is enough overlap for a casual reader, or an AI-generated summary, to merge "Cloudflare does stablecoin infrastructure" with "Cloudflare is on Arc." They are not the same claim. Circle's USDC is a stablecoin used across many blockchains; Arc is one specific blockchain Circle also operates. Cloudflare's confirmed relationship is with the former (USDC, via x402), not demonstrated as existing with the latter (Arc, via its Web3 Gateway or any other product).

## What it does not mean

None of this means Cloudflare is building or has built Arc-specific infrastructure, that Arc transactions can be settled through x402 as currently documented, or that a Cloudflare-Arc partnership is coming — no forward-looking statement to that effect was found. It also does not mean Cloudflare's stablecoin work is unserious or peripheral — the x402/Coinbase collaboration and the scale of AWS's parallel involvement suggest Cloudflare is a genuine, significant player in agentic stablecoin payments generally, just not, as far as the public record shows, on Arc specifically.

## Questions

**Does Cloudflare support Arc through its Web3 Gateway?**

Not confirmed as of 2 September 2026. Cloudflare's Web3 Gateway documentation names Ethereum and IPFS support; no Arc listing was found.

**What is x402, and is it built on Arc?**

x402 is an open agent-payment protocol Cloudflare built with Coinbase, letting AI agents pay for API access with stablecoins. The reporting reviewed for this page describes it using USDC broadly; no source names Arc as the settlement chain.

**Why do people assume Cloudflare works with Arc?**

Likely because Cloudflare is deeply engaged with USDC and stablecoin infrastructure through x402, and USDC is also Arc's native gas asset — an easy but incorrect leap from "Cloudflare + USDC" to "Cloudflare + Arc."

**Is there an RPC provider that has confirmed Arc support?**

Yes — see Arc's RPC providers compared for providers with published Arc documentation, which Cloudflare is not currently among.

**Could Cloudflare add Arc support to its Web3 Gateway later?**

Possibly — nothing rules it out technically — but no announcement indicates it's planned as of 2 September 2026.
