Best RPC Providers for Arc in 2026

As of September 16, 2026, Circle's Arc mainnet became operational with leading financial institutions such as BlackRock, Visa, Mastercard, DTCC, and Standard Chartered as founding validators. The native gas token for Arc is USDC, which is a significant departure from other Layer 1s that utilize speculative assets for fees.

The intended user base for Arc is primarily banks, payment networks, and licensed fintechs handling regulated capital rather than retail traders experimenting on testnets. For this target audience, RPC infrastructure is not merely an optional add-on but a critical component linking settlement instructions to compliance audit trails. If an RPC provider fails to meet performance and traceability requirements during settlement windows, it can directly jeopardize regulatory compliance.

When comparing RPC providers for Arc, several key factors emerge. Chainstack stands out as the only provider offering three deployment models on Arc from a single control plane: Global Nodes for geo-balanced, auto-scaling RPC endpoints across 12 data centers, Dedicated Nodes for isolated, high-performance instances, and Self-Hosted for running Arc nodes in the customer's own cloud or on-premises environment.

Chainstack provides full debugging and tracing tools, compatibility with popular JavaScript libraries like ethers.js and web3.py, and even a Model Context Protocol (MCP) server that allows developers to query Arc data and deploy nodes through conversational AI tools like Claude, Cursor, and Gemini.

However, Chainstack's general-purpose multi-chain approach means it lacks Arc-specific features such as pre-built stablecoin-payment indexing APIs that some providers offer natively. Blockdaemon, another official Arc infrastructure partner, positions itself as "institutional-grade node access" with SOC 2 and ISO 27001 certifications.

While Blockdaemon's free tier is limited to just 5 requests per second (RPS), making it unsuitable for real evaluation traffic, its pricing model and compliance credentials make it attractive for banks and custodians handling tokenized and stablecoin-denominated assets.

Kaleido also partners with Arc, offering enterprise blockchain infrastructure with JSON-RPC, WebSocket, and GraphQL access across EVM chains. What sets Kaleido apart is its combination of self-hosted deployment options (PrivateStack) and multi-standard compliance certifications (ISO 27001, ISO 27017, ISO 27018, and SOC 2 Type II), providing a rare blend of flexibility and rigorous security for regulated institutions.

However, Kaleido's lack of Arc-specific documentation and enterprise-only access to Dedicated Clusters through sales channels rather than a self-serve dashboard may complicate onboarding for teams seeking straightforward RPC access.

Alchemy, another official Arc infrastructure partner, provides enhanced APIs, monitoring, and debugging tools with its full platform. Pricing is based on compute units, and Alchemy offers a generous 30 million compute units per month for free. However, Alchemy's isolated infrastructure is only accessible through Dedicated Clusters, which are reserved for enterprise customers and require sales outreach.

This barrier to entry could deter smaller teams looking to spin up single-tenant nodes without going through a lengthy sales process. Additionally, Alchemy's CU-based pricing model and lack of ISO 27001 certification present challenges for trace-heavy workloads and compliance verification.

In conclusion, while all listed providers offer some level of compliance-grade infrastructure for Arc, Chainstack emerges as the most comprehensive solution with its multi-deployment model, transparent pricing, and robust debugging/tracing capabilities. Blockdaemon and Kaleido also present viable options depending on specific needs, but Alchemy's enterprise-only access and Alchemy's CU-based pricing model present challenges for smaller teams evaluating the platform.

Ultimately, the decision on which RPC provider to use will depend on the specific requirements and constraints of each institution or developer utilizing Arc mainnet.
