Question 1

Solana Validator APIs: Vote Accounts, Epoch Data & Monitoring

Accepted Answer

Solana validator APIs are not a single endpoint. They fall into several categories: core JSON-RPC methods for raw network state, specialized vote-account and epoch-data APIs, and monitoring or analytics APIs that aggregate validator performance. For validator operations, start with Solana JSON-RPC methods such as getVoteAccounts, getEpochInfo, getBlockProduction, and getLeaderSchedule to query vote accounts, identity, commission, stake, and epoch progress. Use specialized APIs when you need normalized historical credit performance, skip rate, vote distance, or alerting. Public clusters like https://api.mainnet-beta.solana.com and https://api.devnet.solana.com are useful for development, but production validator workflows often need a dedicated or high-availability RPC endpoint with WebSocket support and predictable rate limits. Check current plan terms because public limits can change. Developer teams should separate raw RPC methods from specialized data APIs to avoid integration friction. OnFinality offers a Solana RPC endpoint with HTTPS/WebSocket access and archive support on mainnet; current coverage and regional availability are listed on /networks/solana.

Question 2

Shared vs Dedicated Solana RPC Cost: Pricing Models & TCO

Accepted Answer

Shared Solana RPC plans are usually consumption-based, charging by request volume, compute units, or data transfer. This keeps costs low for development, staging, and moderate production traffic because you pay primarily for what you use. Dedicated Solana RPC nodes typically carry a higher fixed monthly cost, but that cost buys reserved CPU, memory, storage, and bandwidth; predictable resource isolation; and more configuration control. The right choice depends on traffic shape, latency sensitivity, WebSocket volume, and operational overhead—not just the list price. For low or intermittent usage, shared endpoints are usually the lower total cost. For sustained high volume, heavy account indexing, real-time trading, or custom node settings, a dedicated node may have better unit economics and lower operational risk. However, exact break-even points vary by provider, method mix, and compute weighting, so teams should measure actual usage before comparing quotes. Public endpoints such as https://api.mainnet-beta.solana.com are useful for testing but are not a production cost plan. See the RPC pricing page and the Solana network page for current plan details.

Question 3

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 4

Question 5

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 6

How do I set up a custom RPC for Optimism?

Accepted Answer

Setting up a custom RPC for Optimism means configuring your wallet or dApp to use a specific endpoint instead of the default public one. This guide covers the chain settings you need, how to add Optimism to MetaMask, and how to choose a reliable RPC provider for production use.

Question 7

ZKsync Uptime: What to Monitor and How to Keep Your dApp Resilient

Accepted Answer

ZKsync uptime refers to the availability of the ZKsync network and its RPC endpoints. While the network's official status page tracks sequencer and API health, your dApp's reliability also depends on your RPC provider's redundancy and failover strategy. This article explains what to monitor, how to evaluate providers, and how to build resilience into your stack.

Question 8

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 9

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 10

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 11

Dedicated BNB Nodes: Shared vs Private BSC Infrastructure

Accepted Answer

Dedicated BNB nodes are single-tenant BNB Smart Chain (BSC) infrastructure that gives your application exclusive access to compute, memory, storage, and bandwidth, instead of competing with other users on a shared RPC endpoint. They matter when you need predictable capacity for production workloads like trading bots, indexers, wallets, or DeFi frontends, or when you require archive state, custom configuration, trace/debug methods, or backend privacy. Shared endpoints are cost-effective for prototyping and bursty development traffic, but can introduce noisy-neighbor risk, rate limits, and variable latency. A dedicated BNB node isolates your workload, removes shared throttling, and lets you tune node flags, retention, and access controls. You should consider upgrading when sustained request volume consistently approaches shared limits, when your queries need historical state at specific blocks, or when you cannot tolerate latency spikes during BSC network activity. Before committing, benchmark your current RPC demand, verify WebSocket stability, archive support, monitoring, and failover options, and compare managed clusters with self-operated builds.

Question 12

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.
