RedStone is named in Circle's official Arc oracle documentation as of 2 Sep 2026. Here's what that listing does and doesn't confirm. > Circle's own Arc developer documentation names RedStone as one of five oracle networks for Arc, at `docs.arc.io/arc/tools/oracles`, as of 2 September 2026. That is a direct, primary-sourced correction to earlier reporting on this page, which found no dated RedStone-Arc announcement anywhere and treated the relationship as unconfirmed. It's worth being precise about what changed: Circle's documentation names RedStone as a vendor for Arc. It does not state a mainnet deployment date, a signed partnership, or which specific feeds are configured — Arc has no mainnet until 16 September 2026, and the listing itself carries no scoping statement either way. > **Builds on Arc:** Named oracle vendor for Arc, offering builders modular price and market-data feeds. · **Role:** Serves · **Category:** Developer Infrastructure → Oracles · [Project page](/project/redstone) ## What RedStone actually is RedStone is a blockchain oracle network, providing price feeds and other off-chain data to on-chain applications — the same general category of product as Chainlink and Pyth. Its own materials describe a modular architecture supporting push, pull, and hybrid delivery models across crypto assets, liquid staking and restaking tokens, real-world assets, and custom feeds. It has documented integrations across a wide range of chains and has been covered by industry research as one of the faster-growing oracle providers by chain-coverage count. ## What changed, and what the source actually says Circle's Arc documentation publishes a dedicated oracles reference page listing five named vendors: Chainlink, Chronicle, Pyth, RedStone, and Stork. RedStone's entry describes it as a "modular oracle network for secure, real-time price feeds and specialized market data," supporting multiple delivery models across diverse asset classes — language consistent with RedStone's own public positioning. This is a Circle-published developer-documentation listing, fetched directly for this page on 2 Sep 2026, and it is a materially stronger form of evidence than the general news and blog searches that previously found nothing: Circle itself, not a secondary aggregator, is the one naming RedStone as an Arc oracle vendor. ## What this listing does and doesn't establish Being named on Circle's oracle-vendor page means Circle's developer documentation lists RedStone as an oracle provider for Arc. It does not by itself mean RedStone has a mainnet deployment, a press-released partnership, or a specific feed live and configured. Arc's own node-providers page explicitly scopes its listed RPC providers to testnet; the oracles page carries no equivalent scoping sentence for any of its five named vendors, RedStone included. This guide won't read a scoping statement into that silence — RedStone's integration could be testnet-only or could extend further; neither is confirmed, since Arc mainnet doesn't exist yet for anything to be readied against. What can be said plainly: RedStone is named in Circle's own developer documentation as an oracle vendor for Arc, as of 2 September 2026, and that's a primary source, not a claim relayed secondhand. ## The Tempo data point, for context RedStone also has a confirmed, dated integration with Tempo — reported by The Block — as an oracle data provider for Tempo's mainnet, launched 18 March 2026 with Stripe and Paradigm backing. Worth noting for context, but it no longer carries the weight it did when no Arc-specific source existed: RedStone now has a documented presence in both ecosystems. ## Relationship to Arc, as of 2 Sep 2026 | | | |---|---| | **Role** | Serves — Developer Infrastructure → Oracles | | **Confirmed by** | Circle's own Arc developer documentation (`docs.arc.io/arc/tools/oracles`) | | **Status** | Named in Circle's official vendor documentation; mainnet deployment and specific feed availability not separately stated | | **What it does not mean** | A signed partnership, a press release, a mainnet deployment, or a specific live feed — the documentation listing does not claim any of those | ## What would move this from "named" to "deployed and live" RedStone's own site or documentation explicitly listing Arc as a supported network, a specific feed address published for Arc (testnet or mainnet), or a dated joint announcement from either company would each add independent confirmation beyond Circle's documentation listing alone. None of those was found as of 2 Sep 2026 — this page relies on Circle's own vendor page as its primary source and will update if RedStone's own materials add Arc-specific detail. ## How RedStone compares to Arc's other named oracle vendors Circle names five vendors with no ranking among them: Chainlink (also a named integration partner in Circle's 5 August 2026 founding-validator release), Chronicle (Sky's originating oracle, offering price feeds and proof-of-asset attestations), Pyth (with an additional dated, testnet-scoped confirmation from July 2026 coverage), RedStone, and Stork (ultra-low-latency, pull-based). All five sit on the documentation page at the same evidence tier — a named vendor listing — except where independent corroboration exists beyond it, as with Chainlink and Pyth.

That confirms a documented relationship; it does not by itself confirm a mainnet deployment or a specific live feed. **Is this the same as a partnership announcement?** No — a Circle documentation listing is Circle naming a vendor in its developer reference, not a press release or a joint announcement from either company. Both can be true at once; only the documentation listing is currently sourced here. **Has RedStone integrated with a comparable chain?** Yes — RedStone is separately confirmed as an oracle data provider for Tempo, a direct Arc competitor stablecoin chain that reached mainnet 18 March 2026. **Which other oracle providers does Circle name for Arc?** Chainlink, Chronicle, Pyth, and Stork, alongside RedStone — all five listed on Circle's Arc oracles documentation page as of 2 Sep 2026. See Built on Arc's oracle comparison guide. **Does Circle's listing say whether RedStone is live on Arc mainnet?** No — the documentation page names RedStone as a vendor without stating mainnet-versus-testnet scope for any of its five listed oracles. Arc itself has no mainnet until 16 September 2026.
