Question 1

Shared vs Dedicated Solana RPC: Performance, Isolation & Scaling

Accepted Answer

Shared Solana RPC nodes are a practical entry point for development, staging, and moderate production traffic. They provide managed JSON-RPC and WebSocket access without requiring teams to operate their own infrastructure. However, because capacity is shared across tenants, performance can vary under load: response times may widen, rate limits may be enforced, and WebSocket subscriptions can become less stable when another tenant generates heavy traffic. Dedicated Solana RPC nodes reserve CPU, memory, storage, and network capacity for a single workload. This isolation usually reduces latency variance and makes throughput more predictable, which matters for trading bots, real-time dashboards, games, and high-frequency indexing. The tradeoff is cost and operational ownership: dedicated access has a higher fixed cost, and teams may need to plan monitoring and failover. The right choice depends on evidence, not guesswork. Start with shared access, measure p50/p95 latency, error rates, rate-limit hits, and WebSocket reconnects, then move to dedicated when those metrics show shared capacity is constraining your product. OnFinality offers shared Solana RPC at /networks/solana and a dedicated node path at /rpc-assistant/dedicated-solana-node.

Question 2

Best Ethereum RPC Services for Performance Monitoring in 2025

Accepted Answer

Performance monitoring for Ethereum RPC endpoints means tracking latency, error rates, throughput, and method-level behavior over time. This article explains what to measure, how to build a monitoring probe, and how to evaluate RPC providers for observability, including OnFinality's Ethereum RPC service.

Question 3

PublicNode Rate Limits: What to Expect and How to Plan Around Them

Accepted Answer

PublicNode offers free RPC endpoints for many chains, but like most public services it applies rate limits to protect shared infrastructure. This article explains how those limits typically work, how to detect them, and when to move to a dedicated or commercial RPC provider for production workloads.

Question 4

Sui gRPC Providers: Public, Managed & Dedicated RPC Compared

Accepted Answer

Sui gRPC providers give applications a typed, streaming path to Sui data, but access models differ significantly. Public Foundation gRPC endpoints can suit prototypes and low-volume tooling; evaluate their current limits, support, and production terms before depending on them. Managed gRPC providers operate shared endpoints with documented capacity, monitoring, and support, making them a practical default for dApps, indexers, and backend workers. Dedicated Sui gRPC nodes isolate your workload on private infrastructure and are justified when burst behavior, latency, or compliance requirements outgrow shared capacity. The evaluation should be gRPC-first: confirm LedgerService and StateService read support, TransactionExecutionService for ExecuteTransaction and SimulateTransaction, and SubscriptionService for SubscribeCheckpoints, SubscribeTransactions, and SubscribeEvents. Also verify rate limits, burst allowances, regions, failover, and incident communication before moving production traffic. OnFinality provides managed Sui gRPC and RPC infrastructure for mainnet and testnet, with a path to dedicated nodes when workloads need isolation. Start from /networks/sui to review current Sui network support.

Question 5

Dedicated Solana RPC Nodes: Shared vs Private Infrastructure

Accepted Answer

A dedicated Solana RPC node is a single-tenant Solana RPC endpoint reserved for your application or team. It runs the same Solana client software as a shared node, but with isolated CPU, memory, storage, and network capacity. Shared RPC—whether a public endpoint or a managed multi-tenant service—is usually faster to adopt and cheaper to operate, but it can be affected by other users' traffic and rate limits. Dedicated infrastructure gives you predictable capacity, custom node configuration, and stronger isolation for latency-sensitive or high-volume workloads. It also costs more and adds operational responsibility unless you use a managed service. Choose shared first for prototypes, staging, and moderate production traffic. Move to dedicated when you see sustained rate limiting, need consistent latency for trading or real-time indexing, require custom streaming or node configuration, or want architectural separation between critical and non-critical workloads. Use the checklist and comparison table in this guide to evaluate costs, capacity, and workload fit before committing.

Question 6

What are private RPC endpoints for dapps and when should you use them?

Accepted Answer

A private RPC endpoint is a unique URL with an API key that gives your dapp its own authenticated lane into a node provider's infrastructure. Unlike public endpoints shared by all users, private endpoints offer dedicated rate limits, better reliability, and observability. This guide explains the differences between public, private, and dedicated endpoints, and helps you decide which one your dapp needs.

Question 7

What is the best JSON-RPC API provider for blockchain projects?

Accepted Answer

Choosing a JSON-RPC API provider is a critical infrastructure decision for any blockchain project. The best provider depends on your specific workload, chain requirements, and budget. This article outlines the key evaluation criteria—from method support and data access to pricing models and failover strategies—to help you make an informed choice.

Question 8

What is an Abstract RPC provider and how do you evaluate one?

Accepted Answer

An Abstract RPC provider gives your dApp a JSON-RPC endpoint to the Abstract Layer 2 network, which is a zero-knowledge rollup built on the ZK Stack. Providers handle node operation, load balancing, and API access so you can focus on building. This article explains what to look for in an Abstract RPC provider, how to compare options, and how to connect your app.

Question 9

How to Choose a Kaia RPC Provider for Production Apps

Accepted Answer

Choosing a Kaia RPC provider means balancing reliability, latency, data access, and pricing against your app's traffic patterns. Public endpoints are fine for prototyping, but production apps often need a managed provider with higher rate limits, WebSocket support, and archive data. This guide walks through the key criteria and common pitfalls so you can pick infrastructure that won't break under load.

Question 10

Base RPC Providers: Public, Managed & Dedicated Options

Accepted Answer

Base RPC providers fall into three broad tiers: public endpoints, shared managed endpoints, and dedicated nodes. Public access, including OnFinality’s public Base endpoint, is convenient for experiments and smoke tests but is rate-limited shared infrastructure and not suitable for production. Shared managed access adds API-key enforcement, higher capacity, clearer request limits, and optional archive or Trace support, making it appropriate for many development, staging, and moderate production workloads. Dedicated Base nodes isolate your traffic, provide custom configuration, and offer stronger monitoring for high-volume or business-critical applications. Before choosing, confirm support for Base mainnet chain ID 8453 and Base Sepolia chain ID 84532, verify archive or Trace availability, check WebSocket transport, test latency from your deployment regions, and review current plan limits, pricing, and support tiers. The most useful comparison is workload fit: how consistently the endpoint behaves under your read, write, subscription, and historical-query patterns, and whether a clear upgrade path exists as demand grows.

Question 11

Fastest Solana RPC: How to Measure Latency & Endpoint Performance

Accepted Answer

Fastest Solana RPC is not a single endpoint; it depends on workload, region, and the methods you call. Latency comes from network round-trip time, server processing, and payload size. A provider with a nearby node and well-tuned hardware may show excellent p50 latency for light reads like `getSlot`, but p95 for heavy methods like `getProgramAccounts` can spike under load. To choose an endpoint, measure from your application's region, test the specific JSON-RPC methods your dApp uses, and track tail latency (p95, p99) rather than averages. Also evaluate WebSocket subscription stability and rate-limit behavior; throttling and retries add perceived delay. Public endpoints like `https://api.mainnet-beta.solana.com` are useful for development but have shared capacity and limits that can change. For production, a managed Solana RPC endpoint or dedicated node can provide more predictable latency. OnFinality offers Solana endpoints (verify current plan details on the [Solana network page](/networks/solana)), but always benchmark against your own workload before committing. A reproducible test suite that captures p50/p95, method-specific response times, WebSocket reconnects, and rate-limit headroom gives you the only reliable comparison.

Question 12

Best Solana APIs for Validators: Monitoring, Data & Operations

Accepted Answer

Best Solana APIs for validators are rarely one product. Validator operators need a small set of purpose-built interfaces: monitoring APIs that expose vote-account and skip-rate telemetry, analytics APIs for epoch-level performance and rewards, RPC endpoints for transaction submission and chain state, and reporting APIs for historical or exported data. The right combination depends on whether you run one validator or a fleet, and whether you need live alerting, historical reporting, or both. Start by mapping the operational jobs—slot health, vote distance, leader slots, stake account changes, reward accrual—to the API categories that actually cover them. Then compare providers on data freshness, authentication, retention windows, and failover behavior. Do not assume that a generic Solana RPC provider or a public endpoint will give you the vote-account and epoch-level detail a validator needs. For production validator operations, a dedicated or reliable shared RPC layer plus a monitoring/data API is often a more practical baseline than a single 'best' API.
