Canonical: https://builtonarc.app/guides/arc-for-developers-provider-map # Mapping the Arc developer stack: who provides what Updated 2026-09-02. RPC, indexing, wallets, account abstraction, oracles, bridging and monitoring for Arc — mapped against what Circle's own docs actually verify. > As of 2 September 2026, a team building on Arc assembles RPC access, indexing, wallet and account-abstraction infrastructure, oracles, bridging, and monitoring largely from third-party vendors, plus a small set of tools Circle publishes directly through its own App Kit. Circle's developer documentation names specific vendors for most of these layers; this guide organizes that list by function and flags where the public record is thinner than the marketing around it. Audit is a separate, project-specific check that applies only to teams deploying or issuing contracts on Arc, not a layer this map sources. ## What counts as confirmed here Two kinds of source carry weight in this map: [docs.arc.io](https://docs.arc.io), Circle's developer documentation, which publishes named vendor lists for RPC, indexing, account abstraction, oracles, and compliance vendors; and a vendor's own published Arc-specific documentation or announcement, independent of Circle's list. A provider in neither is marked assumed or unconfirmed here, not absent — plenty of vendors serving every other EVM chain will likely add Arc support around mainnet without a dedicated announcement beforehand. Built on Arc found no public submission path into Circle's vendor lists; they read as curated directly by Circle, not open to self-listing. Nothing below is ranked. Mainnet is 16 September 2026 — every entry here is testnet-only unless stated otherwise. See [/guides/arc-testnet-vs-mainnet-what-changes-for-builders](/guides/arc-testnet-vs-mainnet-what-changes-for-builders) for the full change inventory. ## RPC and node access Arc's public testnet endpoint (`rpc.testnet.arc.io`) works for local development, but a production app needs a dedicated provider for uptime, rate limits, and monitoring. Circle's docs name four; **GetBlock** publishes independently. None of the five states mainnet endpoint availability as of 2 Sep 2026 — Circle itself has not published an official mainnet RPC URL for anyone to build against yet. **Alchemy** > **Builds on Arc:** Runs dedicated Arc RPC endpoints with enhanced APIs for production apps. · **Role:** Serves · **Category:** Developer Infrastructure → RPC · [Project page](/project/alchemy) **Blockdaemon** > **Builds on Arc:** Offers dedicated Arc RPC endpoints for teams needing uptime guarantees. · **Role:** Serves · **Category:** Developer Infrastructure → RPC **dRPC** > **Builds on Arc:** Provides Arc RPC access with built-in debugging tooling. · **Role:** Serves · **Category:** Developer Infrastructure → RPC · [Project page](/project/drpc) **QuickNode** > **Builds on Arc:** Offers dedicated Arc RPC endpoints with enhanced developer APIs. · **Role:** Serves · **Category:** Developer Infrastructure → RPC · [Project page](/project/quicknode) **GetBlock** > **Builds on Arc:** Publishes its own Arc API reference for RPC access. · **Role:** Serves · **Category:** Developer Infrastructure → RPC ## Indexing and data Circle's docs list five, one of which (thirdweb) also carries a primary role of Account abstraction, covered below. Notably absent as of 2 Sep 2026: Dune, Covalent, and Ponder — none had a public Arc integration Built on Arc could source. That is an absence from the confirmed record, not evidence they won't ship one.

Circle's own **Circle Wallets** sits alongside ten third-party providers Circle documents for account abstraction, plus one — Blockradar — that Circle's grouping files here but this map places under Wallets & Custody instead (see below). Two of the ten have additional independent confirmation: **Dynamic** via a Circle-authored tutorial, **Crossmint** via same-day support when testnet launched. **Safe** and **Alchemy's** account-kit tooling don't appear on Circle's list as of 2 Sep 2026 — an absence, not confirmed non-support.

What exists instead is Circle's own tooling: **CCTP** (live on testnet via a documented TokenMessengerV2 contract) and the Bridge and Unified Balance modules inside Circle's App Kit, routing USDC movement through Circle Gateway rather than a third-party bridge. A team needing non-USDC asset bridging into Arc should treat that as open infrastructure pre-mainnet, not an oversight here. For the end-user mechanics of moving funds onto Arc, Meme Central covers that ground: [How to bridge to Arc](https://memecentral.fun/guides/how-to-bridge-to-arc?utm_source=builtonarc&utm_medium=guide&utm_campaign=arc). ## Compliance monitoring (see Compliance & Analytics) This content lives under Compliance & Analytics, not Developer Infrastructure — it's mapped here because a team assembling its stack sources it alongside RPC and indexing, not because it shares a category with them. Circle's docs name three compliance vendors — transaction monitoring, address screening, and AML/sanctions tooling — a narrower category than runtime security monitoring (contract-level anomaly detection, incident response), where Forta, OpenZeppelin Defender, and Hexagate have no confirmed Arc integration as of 2 Sep 2026.

Read [/guides/arc-smart-contract-auditors](/guides/arc-smart-contract-auditors) before treating any project's audit claim as settled. ## Why Circle's docs are the ceiling of what's confirmable, not the floor Circle's `arc.io/ecosystem` page shapes what's confirmable on Arc at all: a closed, BD-gated partner wall of roughly 100-plus institutional names under 19 filter tags, no public submission form, and no bucket for launchpads, NFT, meme, gaming, or consumer apps. The vendor lists inside Circle's *developer* docs, cited throughout this guide, are the most complete public record of who's building infrastructure for Arc — not necessarily the complete record of who actually is. ## The full infrastructure directory {{entries:category=developer-infrastructure}} This hub also covers entries filed under other categories: see [Compliance & Analytics](/category/compliance-analytics) for the compliance vendors above, and [Wallets & Custody](/category/wallets-custody) for Blockradar and other embedded-wallet and custody providers.

Arc is a Circle product; we are not affiliated with, endorsed by, or operated by Circle.* ## Questions **Is this list of providers ranked by quality?** No. Entries are grouped by function and confirmation status — documented by Circle, self-published, or unconfirmed — only. **Why would Circle publish a vendor list at all if Arc uses standard EVM tooling?** Standard Ethereum tooling — Solidity, MetaMask, ethers.js — works on Arc without Circle's involvement. The docs.arc.io lists read as a curated "known good" set, not a certification, and no public submission path into them was found. **Will more providers add Arc support after the 16 September mainnet?** Plausibly, but Built on Arc doesn't speculate on unannounced roadmaps. Thin categories today — bridging aggregators, runtime security monitoring — are worth rechecking after launch. **Does a provider's absence from Circle's list mean it doesn't support Arc?** No. It means neither Circle's docs nor the provider's own material confirmed support as of 2 Sep 2026 — itself a finding, not a research gap. **Where do I find the mechanics of connecting to Arc — RPC setup, getting testnet USDC?** That's owned by Circle's own docs — see docs.arc.io. **Does this map cover mainnet pricing or fees for any of these providers?** No — vendor pricing is commercial information outside what any source here discloses.
