Question 1

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 2

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 3

It helps developers and infrastructure buyers make informed decisions by comparing Alchemy's offerings against common production requirements.

Question 4

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 5

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.

Question 6

Starknet RPC: Endpoints, Providers, and Best Practices

Accepted Answer

Starknet is a ZK-rollup on Ethereum that uses STARK proofs for scalability. To interact with Starknet, you need an RPC endpoint. This guide covers public and private Starknet RPC endpoints, how to choose a provider, and common troubleshooting tips for developers.

Question 7

How to choose an Optimism RPC provider for your dApp

Accepted Answer

Selecting the right Optimism RPC provider is critical for dApp performance and reliability. This guide covers key evaluation criteria, provider types, and practical setup steps to help you make an informed decision for production use.

Question 8

What should I look for in a dedicated Avalanche node?

Accepted Answer

A dedicated Avalanche node gives you a private RPC endpoint with clear rate limits and full control over your Avalanche infrastructure. This guide covers what to evaluate when choosing a dedicated node provider, including performance, reliability, and support for C-Chain, X-Chain, and P-Chain.

Question 9

Ethereum RPC Infrastructure: Public, Private, Archive & Dedicated Nodes

Accepted Answer

Ethereum RPC infrastructure spans public endpoints, shared managed services, private managed nodes, and dedicated nodes. Public endpoints are free but rate-limited and unsuitable for production. Shared managed RPC offers better reliability and managed operations while still pooling resources across tenants. Private managed nodes provide isolated capacity with predictable performance, while dedicated nodes give full control over node configuration, regions, and failover. The right choice depends on workload: read-heavy dashboards may work on shared RPC, transaction-heavy bots or indexers may need dedicated capacity, and historical queries require archive nodes. Full nodes keep recent state, archive nodes retain all historical state for any block height. Trace and Debug APIs add CPU-heavy methods like debug_traceTransaction, which can affect latency and cost. Production teams should evaluate scaling path, geographic routing, observability, failover behavior, and upgrade operations before committing. Plan by workload, not vendor label, and verify current limits and features on the Ethereum network page.

Question 10

How to choose a Starknet RPC provider for your dApp

Accepted Answer

# How to choose a Starknet RPC provider for your dApp Starknet is a validity rollup (ZK-rollup) on Ethereum that offers high throughput, low gas costs, and Ethereum-level security. To interact with Starknet, your dApp needs a reliable RPC (Remote Procedure Call) provider. This guide explains what to look for in a Starknet RPC provider, compares shared vs dedicated node options, and helps you select the best infrastructure for your project. Whether you are building a DeFi protocol, a game, or an NFT marketplace on Starknet, choosing the right RPC provider is critical for performance, reliability, and cost. We cover the key criteria—latency, availability, archive data support, pricing models, and network coverage—so you can make an informed decision.

In practice, the useful question is not just whether an endpoint exists. Teams should check supported methods, traffic shape, monitoring, pricing, and the path from testing to production. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks after using this checklist so you can test the endpoint against your real methods.
