Question 1

What are the key differences between dedicated and shared node access for blockchain applications?

Accepted Answer

Dedicated node access gives you exclusive use of a blockchain node, while shared node access means multiple users connect to the same endpoint. The choice affects performance, reliability, privacy, and cost. To help you decide, we compare isolation, rate limits, latency, customization, and pricing.

Question 2

Chainstack vs Other RPC Providers: What to Evaluate Before Choosing

Accepted Answer

A practical comparison guide for developers evaluating Chainstack against other RPC providers. Covers key criteria including pricing models, network support, latency, reliability, and developer experience. Helps infrastructure buyers make an informed decision based on workload requirements and budget.

Question 3

Which RPC providers offer enhanced APIs specifically tailored for NFT data?

Accepted Answer

Several RPC providers now offer enhanced APIs that simplify NFT data access—including metadata, ownership, transfers, and spam filtering—without requiring custom indexing. These APIs are especially valuable for NFT marketplaces, gaming dApps, and wallet applications. Providers like Helius, Alchemy, and QuickNode lead with Solana and Ethereum NFT endpoints, while OnFinality provides flexible RPC infrastructure that can be paired with dedicated node setups for custom NFT data needs.

Question 4

What is an Arbitrum RPC node and how do you choose the right one?

Accepted Answer

An Arbitrum RPC node is an endpoint that lets your dApp read and write data on Arbitrum One, Nova, or Sepolia testnet. Choosing the right node provider means evaluating throughput limits, archive data support, WebSocket availability, and failover patterns. This article covers chain settings, public vs. private endpoints, and a decision checklist to help you select infrastructure that matches your production needs.

Question 5

Can you recommend a flexible and cost-effective RPC solution for Web3 teams?

Accepted Answer

Choosing an RPC provider that balances flexibility and cost is critical for Web3 teams scaling from prototype to production. This article outlines the key factors to evaluate—pricing models, feature sets, network coverage, and support—and provides a decision framework to help you select a solution that fits your workload without overpaying.

Question 6

Dedicated Sui gRPC Nodes: Streaming, Capacity & Isolation

Accepted Answer

Dedicated Sui gRPC nodes give your team an isolated full-node environment for high-throughput Sui data access. Instead of sharing rate-limited public or multi-tenant endpoints, you operate a node sized for your indexers, backend services, and subscription consumers. The gRPC API uses Protocol Buffers over HTTP/2, which makes checkpoint, transaction, and event streams more efficient than polling JSON-RPC. Dedicated capacity helps when you need stable throughput for backfills, multiple concurrent stream consumers, or transaction submission and simulation without noisy neighbours. You still own the operational surface: sync lag, disk growth, upgrades, and monitoring. The Sui gRPC surface includes LedgerService, StateService, TransactionExecutionService, and SubscriptionService. Streaming workflows such as SubscribeCheckpoints, SubscribeTransactions, and SubscribeEvents are central to low-latency indexing; ExecuteTransaction and SimulateTransaction support write and simulation paths. A dedicated node is not a managed magic box. Plan for state growth, snapshot recovery, TLS, load testing, and failover before production. This guide covers capacity planning, isolation, replay, monitoring, and full-node lifecycle decisions without vendor rankings or invented performance claims.

Question 7

dRPC vs Alchemy: What Should Web3 Developers Compare?

Accepted Answer

dRPC and Alchemy serve different developer needs. Alchemy provides a full-stack platform with enhanced APIs, webhooks, and analytics, ideal for EVM-heavy projects. dRPC focuses on multi-chain access with decentralized routing and clear rate limits. This article breaks down the key differences to help you decide based on your workload, chains, and budget.

Question 8

What Is an RPC Node API and How Do You Use It?

Accepted Answer

An RPC Node API is a remote interface that lets your application communicate with a blockchain node using JSON-RPC. It abstracts away the complexity of running node software, providing endpoints for reading chain data, sending transactions, and subscribing to events. This article explains how RPC Node APIs work, when to use a managed provider, and how to evaluate endpoints for production use.

Question 9

How to Choose an Avalanche RPC Provider for Production dApps

Accepted Answer

Selecting the right Avalanche RPC provider is critical for dApp performance, reliability, and cost. This article covers the key evaluation criteria—latency, throughput, archive support, and pricing models—and helps you compare providers for C-Chain, X-Chain, P-Chain, and subnets. Whether you need a shared public endpoint or a dedicated node, we outline what to check before committing to production infrastructure.

Question 10

How to Evaluate Alchemy as an RPC Provider for Your Web3 Project

Accepted Answer

This article provides a structured framework for evaluating Alchemy as an RPC provider, covering key criteria such as feature set, pricing model, performance considerations, and developer experience. It helps developers and infrastructure buyers make informed decisions by comparing Alchemy's offerings against common production requirements.

Question 11

Ethereum RPC Compatibility for Current Network Upgrades

Accepted Answer

Ethereum network upgrades change the behavior of execution-layer JSON-RPC endpoints. Compatibility means the RPC provider has updated nodes to expose new methods, return new block and transaction fields, and continue supporting older calls where backward compatibility is expected. For developers and node operators, this is an operational concern: if an endpoint lags behind a hard fork, requests can fail or return data that no longer matches the chain’s current state. This guide explains how to evaluate compatibility without relying on vendor rankings. Start by checking the provider’s documentation for upgrade support timelines and method availability, then verify behavior on Sepolia before mainnet. Blob-related methods such as eth_getBlobSidecars and eth_blobBaseFee are common post-Dencun additions, but future upgrades may introduce new transaction types or state queries. OnFinality documents current plan details for Ethereum mainnet at /networks/eth and for Sepolia at /rpc-assistant/sepolia-eth-rpc; always confirm live values there. Use the checklist in this article to test any RPC endpoint during an upgrade cycle.

Question 12

Ethereum RPC Nodes: Full, Archive & Dedicated Node Requirements

Accepted Answer

An Ethereum RPC node is a server running Ethereum execution and consensus clients that exposes the JSON-RPC API. Applications use it to query live and historical data—blocks, balances, transaction receipts, logs, and contract state—and to broadcast signed transactions. The choice between full, archive, managed, and dedicated nodes depends on data depth, consistency, and operational capacity. Full nodes serve current chain state and recent history; archive nodes preserve historical state for queries at past blocks and advanced Trace/Debug methods. Managed RPC infrastructure removes sync, storage, client updates, and high-availability engineering. Dedicated nodes add isolated capacity and predictable performance for high-throughput or latency-sensitive workloads but require planning, monitoring, and failover. OnFinality provides Ethereum mainnet and Sepolia RPC access through HTTPS and WebSocket, with plan-dependent rate limits, archive/Trace/Debug availability, and regional endpoints documented on the network page. This guide explains node types, hardware and sync requirements, client and monitoring operations, managed versus self-hosted tradeoffs, and when to choose a dedicated Ethereum RPC node. For developers, the key distinction is whether you need recent state only or historical state depth, and whether you can manage infrastructure or prefer a managed service.
