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

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 4

Binance Smart Chain Developer Guide for BNB Smart Chain

Accepted Answer

Binance Smart Chain, now officially BNB Smart Chain (BSC), is an EVM-compatible layer-1 blockchain with 3-second block times, mainnet chain ID 56, and testnet chain ID 97. Solidity developers can reuse Ethereum tooling—Hardhat, Foundry, OpenZeppelin, ethers.js, and web3.js—with minimal configuration changes. You need a reliable RPC endpoint: OnFinality provides EVM-compatible HTTPS and WebSocket RPC endpoints, Archive support, and trace/API access at https://bnb.api.onfinality.io/public for mainnet and https://bnb-testnet.api.onfinality.io/public for testnet. For testnet development use chain ID 97 and obtain tBNB from a faucet; for mainnet use chain ID 56 and BNB for gas. Deployment follows standard EVM flow: compile, test, estimate gas, send signed transaction, monitor receipt, and verify on BscScan. Handle nonces sequentially to avoid stuck or rejected transactions. Use testnet-to-mainnet promotion with security checks, secret management, contract verification, and rollback readiness. This guide covers Solidity tooling, chain configuration, contract deployment, finality, nonce/gas handling, RPC error diagnosis, and pre-mainnet operational checklists.

Question 5

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 6

What is node infrastructure and how do you evaluate it for Web3 projects?

Accepted Answer

Node infrastructure refers to the hardware, software, and network components that run blockchain nodes to support decentralized applications. This guide explains the core concepts, provides a decision checklist for choosing between self-hosted and managed solutions, and offers practical evaluation criteria for developers and infrastructure buyers.

Question 7

Moonriver RPC: Endpoints, Configuration, and Best Practices

Accepted Answer

Moonriver is an Ethereum-compatible canary network on Kusama, ideal for testing dApps before deploying on Moonbeam. This guide covers Moonriver RPC endpoints, how to configure wallets and tools, and how to choose a reliable RPC provider for production use.

Question 8

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 9

What is the Acala Network and how do I connect to it?

Accepted Answer

The Acala Network is a decentralized finance (DeFi) hub built on Polkadot, offering cross-chain liquidity, liquid staking, and an EVM-compatible smart contract platform. This guide covers Acala's architecture, how to connect via RPC endpoints, and key considerations for developers building on Acala.

Question 10

Aleph Zero RPC: Endpoints, Setup, and Provider Selection

Accepted Answer

This guide covers Aleph Zero RPC endpoints for both mainnet and testnet, how to connect your dApp or wallet, and key criteria for selecting an RPC provider.
