Solana’s Recent Resurgence and the RPC Bottleneck
Solana’s recent comeback has highlighted a recurring choke point in the blockchain ecosystem: the RPC layer that is essential for every wallet, decentralized exchange (DEX), bot, and indexer to read state and stream program logs. RPC, which stands for remote procedure call, functions much like Solana’s nervous system — enabling instant queries and continuous log streams between applications and the blockchain, allowing every swap, bot tick, and wallet click to translate into a timely state.
During periods of increased traffic, such as airdrops, hot mints, or memecoin frenzies, the variance between a responsive RPC and a congested one determines whether orders get filled or simply time out. For instance, early in 2024, Solana’s fail rate temporarily soared to 75% due to bot-driven order flow, which compelled teams to reassess their infrastructure assumptions.
The Importance of Low-Latency RPC
The stakes on Solana are particularly high, as the chain aims for 400 ms slots (typically 400–600 ms in practice). Block hashes expire in around 60–90 seconds, leaving little room for sluggish reads or dropped streams; if clients cannot keep pace, transactions fail. Therefore, high-frequency applications necessitate consistently low-latency RPC, rather than merely impressive peak throughput on paper.
According to Messari, daily non-vote transactions averaged about 95 million in Q1 2025, primarily driven by DEX activity. Aggregators such as Jupiter now handle tens of billions in monthly volume, which increases pressure on subscriptions and read endpoints, especially during volatile market conditions.
Challenges with Current RPC Solutions
Most “premium” RPC tiers often mean one tenant, one node, and one queue. While this isolation enhances predictability, it forces lightweight requests and heavy streams to vie for the same CPU, memory, and network resources. Under mixed loads, queues can elongate, tail latencies can rise, and prolonged streams can be interrupted — prompting teams to overprovision hardware that is only necessary for a few hours each week.
Hybrid RPC Design for Improved Efficiency
A hybrid design separates tasks into specific lanes and directs each request based on its weight and type. Lightweight reads are directed to high-concurrency shared clusters that are fine-tuned for throughput and caching, while streaming tasks are placed on dedicated computing resources optimized for long-lived, bandwidth-heavy flows through WebSockets or gRPC. This setup diminishes head-of-line stalls and provides smoother subscriptions even during significant spikes in activity.
InstantNodes presents itself as a hybrid RPC provider for Solana tailored for enterprises and institutions. Its routing engine allocates small, cache-friendly requests to shared clusters while reserving heavy operations — such as Geyser logs, program subscriptions, and state diffs — for dedicated computing resources. The company highlights its focus on optimized caching, layered load balancing, and EU/US multi-region redundancy to maintain tight tail latency and high availability.
The team asserts that its infrastructure can support up to 60,000 requests per second, achieve sub-50 ms targets for read traffic, and offer three or more backup nodes per region. Security and correctness features include SSL/TLS transport, DDoS protections, private endpoints with authentication, and a stated goal of 99.999% data accuracy, with real-time monitoring at half-second intervals. Teams can set per-method limits, access analytics, and utilize gRPC through the Stoner Geyser plugin for efficient streaming.
More Read
Real-World Application and Benefits
Consider a DEX aggregator during peak times. Millions of short reads assist in price discovery, while a smaller group of clients maintains high-fidelity program and log subscriptions. In a single-queue setup, long-lived streams and bursts of reads frequently interfere with one another. InstantNodes’ hybrid RPC can mitigate this collision by directing the reads to clusters designed for concurrency, while isolating the streams on machines optimized for sustained throughput.
This separation yields practical benefits. Caches remain warm and effective for read-heavy endpoints, while streaming nodes sidestep context switching and garbage collection churn caused by surges in short requests. InstantNodes enhances this efficiency with gRPC integration via the Stoner Geyser plugin to transport log data effectively, as noted in their materials.
The company claims that this is a key reason major Solana players, including Jupiter, consider InstantNodes as one of their primary providers — providing real-world evidence that routing by request weight can stabilize production workloads during market volatility.
Considerations for Institutions
For institutions, the underlying architecture is only half of the equation. Operators also need customizable options, observability, and predictable pricing. InstantNodes emphasizes tailored rate limits and allowlists, real-time analytics, and transparent pricing (avoiding opaque “credits”), alongside 8/5 or 24/7 support tiers that align with trading desks. Geographical redundancy across EU and US regions, paired with multiple backups per region and intelligent load-balancing, minimizes blast radius and allows for maintenance without service disruption.
The Future of Solana’s Infrastructure
The next growth phase for Solana will hinge on whether its critical infrastructure can keep pace as consensus throughput expands. Data clearly indicates that transaction volumes are substantial, slots are rapid, and turbulence is occasional. RPC that can adapt under pressure — differentiating between light and heavy requests, dynamically routing, and being instrumented for control — stands to become the standard for teams that rely on low latency. InstantNodes’ hybrid model presents a tangible blueprint with its intelligent and scalable RPC designed for production use.
The InstantNodes team envisions reliably powering high-volume applications as the next wave of Web3 adoption unfolds. With institutional demands on the rise, hybrid RPC is increasingly seen not just as a premium feature but as a fundamental requirement for large-scale execution.
