Production-grade RPC access for Arbitrum
On Arbitrum, RPC problems become financial problems. Smart Router orchestrates your providers so lending, perps, and trading apps keep reading fresh state and submitting transactions cleanly.
Smart Router sits above the Arbitrum providers you already use
Point your application at Smart Router and register your existing Arbitrum endpoints behind it. Every request is routed, validated, and observed across the pool, so a single provider event stops being your event.
Magma is not an RPC provider. Keep your commercial endpoints, dedicated nodes, or self-hosted infrastructure. Smart Router orchestrates them.

InfuraArbitrumWhy Arbitrum RPC reliability matters
Arbitrum hosts a deep concentration of DeFi activity, and the applications on it, trading venues, lending markets, perps, and cross-chain apps, depend on RPC access that stays accurate and available under load. When Arbitrum RPC degrades, the consequences are financial: a stale read can produce a wrong price or an incorrect position, and a failed transaction submission can mean a missed opportunity or a stuck user action. On an L2 carrying real value, these are not edge cases.
Arbitrum's characteristics shape the reliability problem. Applications need timely reads of L2 state and dependable submission, and providers can fall behind chain tip, return inconsistent results, or throttle heavy read patterns during volatile markets, precisely when accuracy matters most. Teams relying on a single Arbitrum endpoint absorb every provider hiccup directly and are left doing manual incident response when a market is moving. For L2 teams, strong uptime and monitoring across multiple providers is a baseline expectation.
Reliable, observable, multi-provider Arbitrum RPC access is what keeps DeFi and trading apps correct and available when volatility spikes.

A production-grade layer for Arbitrum traffic
Multi-provider routing
Spread Arbitrum RPC calls across several providers instead of pinning your application to one endpoint.
Automatic failover
When a provider returns errors, times out, or falls behind chain tip, traffic can shift to a healthy provider without manual intervention.
Latency-aware routing
Requests can be directed toward the endpoints performing most reliably at that moment.
Response validation
Cross-check responses from multiple providers to catch stale, inconsistent, or malformed data before it reaches your application.
Provider observability
See per-provider error rates, latency, and health for your Arbitrum traffic in one place instead of stitching together dashboards.
Policy-based routing
Encode routing rules that reflect your priorities, such as preferring a private endpoint for sensitive methods or weighting providers by reliability.
One control plane across chains
Manage Arbitrum alongside every other chain you operate from a single interface.
Common Arbitrum RPC use cases
DeFi applications read prices, pool state, and positions where inconsistent data can drive wrong quotes or liquidations, making validated multi-provider reads valuable. Trading and perps venues need low-latency, dependable access during volatility. Wallets rely on accurate balance and state reads plus reliable submission on Arbitrum. Cross-chain apps coordinate state across networks and cannot afford a lagging L2 endpoint. Rollup and infrastructure teams need strong uptime and cross-provider monitoring to meet their own reliability commitments. Analytics and indexing teams follow Arbitrum at chain tip and need consistency across providers. Security platforms monitor Arbitrum in real time. Magma gives these teams a shared routing and validation layer instead of per-app L2 failover code.
Use Smart Router with your existing Arbitrum RPC providers
Magma is provider-agnostic and works with the Arbitrum providers you already run, commercial endpoints, dedicated nodes, or self-hosted infrastructure. You connect them to Magma, which routes across them, monitors their health and latency, and applies your failover and validation rules. There is no migration and no lock-in. For L2 teams that already blend providers for cost and coverage, Magma makes routing between them a policy decision rather than custom code.
Reduce single-provider risk
A single Arbitrum RPC provider concentrates risk that value-carrying apps cannot ignore. Availability risk: one provider's outage or throttling during volatility takes your app offline when users need it most. Latency risk: one endpoint's slowdown becomes your users' slowdown, with no fallback. Data-integrity risk: with nothing to compare against, a stale or incorrect read flows into pricing, positions, or submissions. Distributing Arbitrum traffic across providers with failover and validation turns these into automatic routing decisions instead of incidents.
Multi-chain RPC infrastructure from one control plane
Arbitrum teams almost always operate other chains too, Ethereum and additional L2s among them. Building separate failover, monitoring, and routing for each network is duplicated effort and a source of uneven reliability. Magma provides one control plane, with consistent policies and observability, across Arbitrum and every other chain you run, so reliability does not vary network to network.

FAQs about Arbitrum RPC routing
It is directing Arbitrum RPC calls across one or more providers based on health, latency, and policy rather than a single endpoint. Magma provides this layer above your existing Arbitrum providers.
