Alchemy on Arc: confirmed RPC support, scoped to testnet

Alchemy has a confirmed Arc relationship on two fronts: a dedicated, live Arc Testnet RPC page on its own site, and a partnership announcement published through Arc's own community channel. As of 2 September 2026, both sources agree on the same scope — testnet. Neither states a mainnet timeline, and Alchemy does not publish a mainnet Arc endpoint as of this writing, consistent with the fact that Arc itself has not published one either.

What Alchemy actually is

Alchemy is one of the largest blockchain infrastructure and developer-platform companies, providing RPC (remote procedure call) node access plus a broader suite of developer tooling — enhanced APIs, webhooks, and analytics — used by a large share of production Web3 applications across many chains. Whether a chain has confirmed Alchemy support is a meaningful signal for developer accessibility, since Alchemy's tooling is a common default choice for teams that don't want to run their own nodes.

The two confirmations

Alchemy publishes a dedicated page, alchemy.com/rpc/arc-testnet, titled "Arc Testnet RPC URL & devtools" — a live product page rather than a passing mention, listing endpoint access and developer tooling scoped explicitly to testnet. Separately, Arc's own community channel published a blog post, "Arc Partners with Alchemy," confirming the relationship from Arc's side rather than only from Alchemy's marketing. Two sources agreeing independently — one from each side of the relationship — is a stronger evidentiary position than a single-sided announcement.

Why "testnet RPC page exists" is a real confirmation, not a weak one

Unlike a name-drop in a partner list, a live RPC endpoint page with a specific chain identifier is something a developer can point a project at today and get a working connection. That is a functionally different, stronger claim than an announced-but-undocumented partnership. This guide's tiering treats a published, working endpoint as the clearest confirmation tier available pre-mainnet — Alchemy clears that bar for Arc testnet specifically.

What's still open

No mainnet-specific Alchemy Arc endpoint has been published, which tracks with the broader ecosystem fact that Arc's own official mainnet RPC and explorer URLs were not published as of 2 Sep 2026 — no third-party provider, Alchemy included, can publish a verified mainnet endpoint until Arc's own canonical one exists. Rate limits, pricing tiers, and archive-node access specific to Arc through Alchemy are also not independently detailed in the sources reviewed for this page; a developer evaluating Alchemy against other confirmed providers should check Alchemy's current published terms directly rather than assume parity with its general multi-chain pricing.

How Alchemy compares to the rest of Arc's confirmed RPC tier

QuickNode and GetBlock have published dedicated Arc API documentation with endpoint syntax; Alchemy and dRPC both publish specific testnet endpoint pages as well — all four sit in the same "published, testnet-confirmed" tier as of 2 Sep 2026, ahead of major providers like Ankr and Infura, for which no Arc-specific listing was found.
