Alchemy publishes a dedicated Arc testnet RPC page and a partnership post via Arc's own channel. Confirmed, testnet-only, as of 2 Sep 2026. > 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. > **Builds on Arc:** RPC provider giving developers a working Arc testnet endpoint plus dev tooling to build against. · **Role:** Serves · **Category:** Developer Infrastructure → RPC · [Project page](/project/alchemy) ## 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. ## Relationship to Arc, as of 2 Sep 2026 | | | |---|---| | **Role** | Serves — Developer Infrastructure → RPC | | **Confirmed by** | Alchemy's own Arc Testnet RPC page + Arc's community blog post confirming the partnership | | **Status** | Testnet — no mainnet Arc endpoint published by Alchemy | | **What it does not mean** | That a mainnet Arc RPC endpoint exists through Alchemy, or that pricing/rate-limit terms shown for testnet carry over unchanged to mainnet | ## 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.

Arc itself has not published an official mainnet RPC endpoint, so no third-party provider, including Alchemy, has one to publish yet. **How does this compare to QuickNode or GetBlock?** All three sit in the same confirmed, testnet-scoped tier — each publishes dedicated Arc documentation or an endpoint page. See Built on Arc's RPC providers comparison for the full picture, including dRPC and Chainstack. **Is Alchemy's Arc pricing the same as its general multi-chain pricing?** Not independently confirmed in the sources reviewed here — check Alchemy's current published Arc-specific terms directly. **Where do I check Arc's own official testnet RPC, separate from Alchemy's?** Arc's public testnet RPC is https://rpc.testnet.arc.io, documented directly by Arc — Alchemy's endpoint is a third-party alternative offering higher reliability and additional tooling on top of that same underlying network.
