Question 1

What is a Smart Chain RPC URL and how do I connect to BNB Smart Chain?

Accepted Answer

A Smart Chain RPC URL is the HTTP or WebSocket endpoint your wallet, dApp, or backend uses to read BNB Smart Chain state and broadcast transactions. It carries JSON-RPC calls such as eth_blockNumber, eth_getBalance, and eth_sendRawTransaction to a node that is synced with the network.

This page covers the BNB Smart Chain mainnet and testnet settings you need for wallet configuration, gives a working curl and JavaScript example, and explains when a public endpoint is enough versus when a managed RPC API or dedicated node is the better fit for production traffic.

Question 2

Polygon Node Hosting: When to Rent Infrastructure Instead of Running It

Accepted Answer

Polygon node hosting means running the Polygon PoS stack — an Erigon or Bor-style execution client plus a Heimdall consensus client — on infrastructure someone else operates, so your team gets an RPC endpoint, WebSocket access, and archive data without owning the servers. The decision is rarely "can we run a node?" and more often "should we spend engineering time keeping one healthy?"

This article walks through the build-versus-buy tradeoffs for Polygon, the chain settings you need to connect, how to evaluate a hosting provider, and the operational signals that tell you a managed endpoint or dedicated node is the better fit for your workload.

Question 3

Acala Liquid Staking: How LDOT Works and What to Check Before You Stake

Accepted Answer

Acala liquid staking lets you deposit DOT into Acala's staking module and receive LDOT, a transferable derivative token that keeps earning staking rewards while you use it elsewhere in DeFi. This article explains how the flow works, what LDOT represents, and the RPC and API surface you need to read staking state or build a liquid staking integration. It also covers the operational questions developers hit first: which endpoints to use, how to query exchange rates and unbonding state, and when a shared public endpoint is enough versus when a dedicated node fits better.

Question 4

Top RPC solutions with dedicated node access for Solana: how do you evaluate them?

Accepted Answer

Dedicated Solana node access means you get a private RPC endpoint backed by infrastructure reserved for your workload, rather than sharing a public or pooled endpoint with other traffic. That distinction matters on Solana because programs, indexers, and trading systems often need consistent throughput, predictable rate limits, and access to methods like `getProgramAccounts` or WebSocket subscriptions that shared endpoints may restrict or throttle.

This article explains how to evaluate Solana RPC solutions that offer dedicated node access, what to test before committing, and where OnFinality fits as an RPC API and dedicated node infrastructure option. It focuses on practical evaluation criteria and operational tradeoffs rather than marketing claims.

Question 5

Sepolia Public RPC Endpoint: Chain Settings, Faucet, and Debugging

Accepted Answer

A Sepolia public RPC endpoint is a shared, no-signup HTTP URL that lets you read chain state and broadcast test transactions on the Ethereum Sepolia testnet. It is the fastest way to point a wallet, Hardhat, Foundry, or ethers/viem script at Sepolia before you commit to a paid plan.

This page gives you the exact chain settings, a working OnFinality public endpoint, faucet and debugging notes, and a short guide to when a shared endpoint is enough versus when you should move to a dedicated node.

Question 6

BNB Smart Chain Testnet RPC: Chain Settings, Faucet, and Debugging

Accepted Answer

BNB Smart Chain Testnet (chain ID 97) is where you validate contracts, wallets, and indexers before touching mainnet. This page gives you the exact network settings, a working public endpoint, faucet guidance, and the failure modes that waste the most developer time. You will also find a short checklist for deciding when a shared public endpoint is enough and when a dedicated node is the better fit.

Question 7

Solana Validator Setup: What to Prepare Before You Stake SOL

Accepted Answer

Running a Solana validator means operating a voting node that participates in consensus, which requires careful hardware planning, key management, and a reliable RPC connection for monitoring and operations. This guide walks through the practical preparation steps, the tradeoffs between running your own validator versus delegating, and how to keep your node observable once it is live.

You will find a decision-oriented checklist, hardware and network requirements, key generation and vote account setup, monitoring signals, and common failure modes. Where a managed RPC or dedicated node helps, we point to OnFinality's Solana infrastructure as an option for the RPC and observability side of your setup.

Question 8

Arbitrum One Testnet RPC: Which Endpoint Should You Actually Use?

Accepted Answer

Arbitrum One is the mainnet chain (chain ID 42161). The testnet that developers usually mean when they say "Arbitrum One testnet" is Arbitrum Sepolia (chain ID 421614), which uses Sepolia ETH for gas. This page explains the chain settings, how to add the network to a wallet, how to request testnet ETH, and how to debug the errors that show up when a testnet endpoint is misconfigured. It also covers when a shared public endpoint is enough and when a dedicated node or managed RPC API is the better fit for CI pipelines, indexers, and staging environments.

Question 9

PublicNode Solana RPC Endpoint: How to Connect and What to Expect

Accepted Answer

PublicNode offers free Solana RPC endpoints for developers who want to test applications without committing to paid infrastructure. This article explains how to find and use the PublicNode Solana RPC endpoint, what rate limits and reliability to expect, and when to move to a managed or dedicated RPC provider like OnFinality for production workloads.

Question 10

What Is Kilt Mashnet and How Do You Connect to It?

Accepted Answer

Kilt Mashnet is the permissionless mainnet of the Kilt blockchain, designed for decentralized identity (DID) and verifiable credentials. This article explains what Mashnet is, how it differs from the Kilt Peregrine testnet, and how to connect your dApp or wallet to the network using RPC endpoints.

You'll find the official chain settings, configuration examples for common tools, and guidance on choosing an RPC provider for production traffic. Whether you're building identity solutions or just need a reliable endpoint, this page helps you get started quickly.

Question 11

How to Evaluate Ethereum RPC Services for Performance Monitoring

Accepted Answer

Choosing an Ethereum RPC service for performance monitoring means looking beyond raw throughput. You need consistent latency, reliable WebSocket connections, and access to debug or trace methods to diagnose issues. This article outlines the key metrics to track, the methods that matter, and how to structure a monitoring setup that catches problems before users do.

Question 12

What Is a TON Full Node and When Should You Run One?

Accepted Answer

A TON full node stores the complete blockchain state and validates transactions for The Open Network. Running one gives you direct access to TON data without intermediaries, but it requires significant hardware, storage, and ongoing maintenance. This article explains what a TON full node does, the tradeoffs of running versus renting infrastructure, and how to decide which approach fits your project.
