Question 1

Polygon RPC API: Endpoint Settings, Methods, and Debugging

Accepted Answer

The Polygon RPC API is the JSON-RPC interface your app uses to read Polygon PoS state and submit transactions. You connect over HTTP or WebSocket to a node that exposes standard Ethereum-compatible methods such as eth_call, eth_getLogs, and eth_sendRawTransaction. This page covers the exact chain settings, working request examples, and the failure modes developers hit most often. It also explains when a shared public endpoint is enough and when a dedicated Polygon node is the better fit for your workload.

Question 2

Dedicated vs shared node access on Solana: how should you compare RPC providers?

Accepted Answer

Shared Solana RPC pools many callers onto the same endpoints, so throughput and priority depend on what everyone else is doing at that moment. Dedicated Solana nodes give your workload its own capacity, which matters when you rely on high-volume reads, WebSocket subscriptions, or predictable behavior under load. This comparison explains how to evaluate providers on both models, which workloads fit each, and what to check before you commit.

Question 3

How do Solana RPC providers handle rate limiting and usage tiers?

Accepted Answer

Solana RPC providers usually control load with a mix of request-per-second caps, compute-unit budgets, and per-method limits, then package those limits into usage tiers. The tier you land on decides how many requests you can send, which methods stay available, and whether you get shared or dedicated capacity. Understanding the mechanics matters more than memorizing any single provider's numbers, because limits change and your workload profile is what determines which tier actually fits.

This article explains how rate limiting is typically implemented on Solana RPC, how to read a usage tier without getting surprised in production, and how to decide between shared endpoints and dedicated node infrastructure. It also covers the failure signals to watch for and how to test a tier against your real traffic before you commit.

Question 4

Staking KLAY on Klaytn: What Developers Should Check Before You Stake

Accepted Answer

Klaytn (now branded Kaia) uses a delegated proof-of-stake model where KLAY holders can stake through governance councils, public node operators, or liquid staking services rather than running a validator directly. Before you stake, you need to understand the unstaking delay, reward mechanics, and which RPC methods let your app read stake state and validator data reliably.

This page covers the Klaytn staking model, the JSON-RPC calls that matter for staking dashboards and wallets, and how to choose RPC infrastructure that keeps reward tracking and transaction submission responsive. It is written for developers integrating staking features, not for casual holders following a click-through tutorial.

Question 5

What should you evaluate in an Ethereum RPC node provider?

Accepted Answer

An Ethereum RPC node provider runs and maintains Ethereum nodes so your app can read chain state and broadcast transactions over JSON-RPC without operating the client software yourself. The right provider depends on your workload: read-heavy dapps, indexers, trading bots, and bridges each stress different methods and transports. OnFinality offers Ethereum RPC API access and dedicated node infrastructure, so you can start on a shared endpoint and move to isolated capacity when your traffic grows.

Question 6

What is the Binance Beacon Chain explorer and how do you query it?

Accepted Answer

The Binance Beacon Chain was the staking and governance layer of the BNB Chain ecosystem, running alongside BNB Smart Chain before the two were merged in the 2024 opBNB-era consolidation. Its explorer let you inspect validators, delegations, and cross-chain activity. Today, most developers interact with the BNB Chain ecosystem through BNB Smart Chain RPC endpoints instead.

This page explains what the Beacon Chain explorer showed, why it matters for historical lookups, and how to move to the BNB Smart Chain RPC workflow that OnFinality supports for production apps. You can connect to a public endpoint for testing or run dedicated node infrastructure for heavier workloads.

Question 7

Which Solana RPC providers offer dedicated nodes for production apps?

Accepted Answer

Solana's throughput and account model put unusual pressure on RPC infrastructure, so teams that outgrow shared endpoints usually move to a dedicated node. A dedicated Solana node gives you isolated compute and bandwidth for your own workload instead of competing with other tenants on a shared pool. This article explains how to evaluate providers that offer dedicated Solana nodes, what to test before committing, and how to run a safe migration. OnFinality provides Solana RPC API access and dedicated node infrastructure you can compare against other options using the checklist below.

Question 8

Base Node RPC: Endpoint Settings, Chain IDs, and Debugging

Accepted Answer

Base is an Ethereum L2 built on the OP Stack, so its RPC surface looks familiar to any Ethereum developer: JSON-RPC over HTTP, the same eth_* methods, and chain ID 8453 for mainnet. This article covers the Base node RPC endpoint settings you need, how to add Base to a wallet, how to send your first request, and how to debug the failures that show up most often in production. It also explains when a public endpoint is enough and when a dedicated Base node is the better fit.

Question 9

Base L2 on Ethereum: How to Connect and When to Use It

Accepted Answer

Base is an Ethereum Layer 2 network that settles transactions on Ethereum while executing them on its own chain. Developers interact with it through an EVM-compatible JSON-RPC endpoint, which means most Ethereum tooling works with only a chain ID and RPC URL change. This article explains what Base is, how it relates to Ethereum, and how to connect to it reliably.

You will find chain settings, a working connection example, and practical guidance on choosing between the public endpoint and managed or dedicated node infrastructure. The goal is to help you decide how to wire Base into your stack and what to check before moving to production.

Question 10

Solana Devnet RPC: Endpoint Settings, Airdrops, and Debugging

Accepted Answer

Solana devnet is the testing cluster where you validate programs, transactions, and client code before touching mainnet. This page explains how to connect a Solana devnet RPC endpoint, how to get test SOL, and how to debug the failures that show up most often during development.

It also covers when a public devnet endpoint is enough and when a managed or dedicated RPC service such as OnFinality is the better fit for CI pipelines, integration tests, and pre-release staging.

Question 11

What does the Gnosis API expose, and how do you connect to it?

Accepted Answer

The Gnosis API is the JSON-RPC interface exposed by Gnosis Chain nodes. It lets wallets, Safe smart accounts, indexers, and backend services read balances, submit transactions, query logs, and inspect state on a chain that settles in xDAI and runs an EVM-compatible execution layer.

This page covers the chain settings you need, how to make your first request, which methods matter for common Gnosis workloads, and how to decide between a public endpoint and dedicated node infrastructure as your traffic grows.

Question 12

What is an ETH public RPC and when should you use one?

Accepted Answer

An ETH public RPC is a shared, unauthenticated JSON-RPC endpoint that lets any developer read Ethereum data and broadcast transactions without running a node. It is ideal for prototyping, wallet configuration, and low-volume scripts, but shared capacity and rate limits make it a poor fit for production workloads that need consistent throughput, archive data, or WebSocket subscriptions.

This page explains how to connect to an Ethereum public RPC, how to verify it works, and the exact signals that tell you it is time to move to a managed or dedicated endpoint. It also covers chain settings, common failure modes, and a practical migration path to OnFinality RPC when your app outgrows the public tier.
