Question 1

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 2

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 3

Polygon Public RPC: When to Use It and When to Move On

Accepted Answer

A Polygon public RPC is a shared, no-auth HTTPS endpoint that lets you read chain data and send transactions without running your own node. It is ideal for quick tests, wallet setup, and low-volume scripts, but shared capacity means you should not rely on it for production traffic or strict latency targets. This article covers the official public endpoint, chain settings, request examples, rate-limit symptoms, and the point at which a dedicated or managed RPC becomes the better choice.

Question 4

Can you compare dedicated versus shared node access for Solana RPC providers?

Accepted Answer

Shared Solana RPC access pools many applications onto the same node infrastructure, which keeps costs low and setup fast but introduces noisy-neighbour effects during network congestion. Dedicated node access gives your workload its own Solana validator or RPC node, so throughput, rate limits, and upgrade timing are predictable. This article compares both models across latency, rate limits, WebSocket reliability, archive needs, and operational overhead, then helps you decide which fits your Solana workload.

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

What does a Polygon payment gateway API need from RPC infrastructure?

Accepted Answer

A Polygon payment gateway API is the backend layer that watches for on-chain payments, confirms them, and triggers settlement logic. It depends on reliable Polygon RPC access for block scanning, transaction confirmation, and reorg handling. This article explains the RPC requirements behind payment flows and how to evaluate infrastructure for them. OnFinality provides Polygon RPC API access and dedicated node options for teams that need predictable throughput.

Question 9

What are the requirements to run an Optimism node?

Accepted Answer

Running an Optimism node means running an OP Stack execution client (op-geth) alongside op-node, the rollup consensus client that derives L2 state from Ethereum L1. Hardware needs are moderate for a full node, but archive mode, high request volume, and historical log queries push storage and I/O requirements up quickly.

This page covers the practical requirements for CPU, RAM, disk, and bandwidth, the difference between full and archive nodes, and when it makes more sense to use a managed Optimism RPC endpoint or a dedicated node instead of operating the stack yourself.

Question 10

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 11

Sui JSON-RPC: Methods, Endpoints, and How to Use Them

Accepted Answer

Sui JSON-RPC is the standard interface for interacting with the Sui blockchain, enabling developers to query chain data, submit transactions, and subscribe to events. This article explains the core methods, how to connect to Sui endpoints, and common pitfalls to avoid when building on Sui.

Question 12

How do Solana RPC providers compare on rate limits and usage tiers?

Accepted Answer

Compare Solana RPC providers by rate limits, usage tiers, and request types. Learn what to check before choosing a provider, and how to match your workload to the right plan.
