Question 1

Base public RPC endpoints and independent performance metrics: what should you evaluate?

Accepted Answer

Base public RPC endpoints are convenient for prototyping and light reads, but they are shared infrastructure with no guarantees on throughput, rate limits, or availability. Independent performance metrics help you compare latency, error rates, and method coverage, but you should always verify them against your own workload before committing to production.

This article explains how to read Base public RPC endpoint lists, how to interpret independent performance metrics, and when to move from a public endpoint to a managed RPC API or a dedicated Base node. It includes chain settings, a curl example against the OnFinality public Base endpoint, and a practical evaluation matrix.

Question 2

What RPC URL should you use for BNB Smart Chain?

Accepted Answer

The RPC URL for BNB Smart Chain mainnet is https://bnb.api.onfinality.io/public, with chain ID 56 and BNB as the native token. For testnet, use https://bnb-testnet.api.onfinality.io/public with chain ID 97 and tBNB. This article shows how to add the network to your wallet, call JSON-RPC methods, and decide when a public endpoint is enough versus when you need dedicated node infrastructure.

Question 3

How do you access Sui data with RPC and data providers?

Accepted Answer

Sui exposes a JSON-RPC interface for reading objects, transactions, checkpoints, and events, and you connect to it through a fullnode endpoint. The practical question is which endpoint to use: a public fullnode for exploration, a managed RPC API for production traffic, or a dedicated node when you need isolation and predictable capacity.

This reference walks through the Sui RPC surface, how to configure an endpoint, how to query data with curl and JavaScript, and how to decide between public, managed, and dedicated options. It also covers common failure modes and the operational checks that keep Sui data access stable as your app grows.

Question 4

How do you use a Chainlist-style directory to find supported RPC networks and endpoints?

Accepted Answer

Chainlist-style directories exist to solve one problem: mapping a chain ID to a working RPC endpoint so wallets and dApps can connect without guesswork. This article explains how those directories are structured, how to read the network metadata they expose, and how to verify an endpoint before you ship it to production.

It also covers where public directory endpoints stop being enough, what to check when a listed endpoint fails, and how a managed RPC API or dedicated node fits when you need predictable behavior across many chains.

Question 5

BNB Smart Chain public RPC URL: how do you connect and when should you switch?

Accepted Answer

A BNB Smart Chain public RPC URL is a shared HTTPS endpoint that lets wallets, scripts, and dApps read chain data and submit transactions without running a node. The OnFinality public endpoint for BNB Smart Chain mainnet is https://bnb.api.onfinality.io/public, with chain ID 56 and BNB as the native token.

Public endpoints are fine for prototyping, wallet setup, and low-volume reads. For production traffic, archive queries, or WebSocket subscriptions, teams usually move to a managed RPC API or a dedicated node so they control capacity and avoid shared-endpoint contention.

Question 6

Arbitrum RPC Endpoints and Providers: How Do You Pick the Right One?

Accepted Answer

Arbitrum exposes a standard EVM JSON-RPC interface, so any Ethereum-compatible tooling works once you point it at a working endpoint. The real decision is not the method list but which endpoint type fits your workload: a shared public URL for quick tests, a managed RPC API for steady production traffic, or a dedicated Arbitrum node when you need predictable capacity, archive data, or WebSocket subscriptions. This article walks through Arbitrum One and Arbitrum Sepolia chain settings, endpoint options, request examples, and the failure modes that usually push teams off public endpoints.

Question 7

Solana Clusters and Public RPC Endpoints: Which One Should Your App Connect To?

Accepted Answer

Solana runs several distinct clusters — mainnet-beta, testnet, and devnet — and each one exposes its own RPC endpoints, genesis hash, and faucet. Picking the wrong cluster is one of the most common reasons a wallet, dApp, or indexer silently fails, so the first step is always to confirm which cluster your code is actually pointed at. This reference walks through the cluster settings, endpoint options, and debugging steps for each environment, and explains when a public endpoint is enough versus when a managed or dedicated RPC service such as OnFinality is the better fit.

Question 8

Sui RPC on GitHub: Where to Find Endpoints, SDKs, and Node Configs

Accepted Answer

Developers searching for "sui rpc github" usually want one of three things: a working Sui RPC endpoint, the official Sui GitHub repositories that document JSON-RPC and the newer gRPC-based APIs, or example code that connects a client to a Sui full node. This article maps those needs to concrete resources and shows how to move from a public endpoint to infrastructure you can rely on in production.

You will find the Sui JSON-RPC method surface, a curl and TypeScript example, a comparison of public versus managed versus dedicated Sui RPC, and a debugging path for common connection and method errors. OnFinality provides Sui RPC API access and dedicated Sui nodes when you outgrow shared public endpoints.

Question 9

What is the BNB RPC name and how do you configure it?

Accepted Answer

The BNB RPC name is the network label and chain identifier your wallet or library uses to connect to BNB Smart Chain. In practice this means the chain name (BNB Smart Chain), the RPC URL, the chain ID (56 for mainnet, 97 for testnet), the native currency symbol (BNB or tBNB), and the block explorer URL. Getting these values right is what stops "wrong network" and "unknown chain" errors.

This page gives you the exact mainnet and testnet settings, shows how to add the network in MetaMask and in code with ethers or viem, and explains how to pick an RPC endpoint that holds up under real traffic. OnFinality provides BNB Chain RPC API access and dedicated nodes when you need more control than a public endpoint offers.

Question 10

Base RPC API: Endpoint Settings, Marketplace Alternatives, and Production Setup

Accepted Answer

Base RPC is the JSON-RPC interface to the Base L2 network, used to read state, send transactions, and subscribe to events. This page covers the public endpoint, chain settings, and how to evaluate marketplace-style RPC listings for production workloads. You will also find a practical checklist for choosing between shared public endpoints and dedicated node infrastructure, plus debugging steps for common Base RPC failures.

Question 11

What is the Base public RPC URL and which dev tools should you use with it?

Accepted Answer

The Base public RPC URL is a shared, no-key HTTP endpoint that lets you read chain data and send transactions to Base mainnet. OnFinality publishes a public endpoint at https://base.api.onfinality.io/public, and the Base Sepolia testnet equivalent is https://base-sepolia.api.onfinality.io/public. Public endpoints are ideal for prototyping, scripts, and low-volume reads, but they are shared infrastructure, so heavy or latency-sensitive workloads should move to a dedicated or managed RPC plan.

This page explains the chain settings you need (chain ID 8453 for mainnet, 84532 for Sepolia), how to wire the endpoint into common dev tools such as viem, ethers, Foundry, Hardhat, and wallet network configs, and how to decide when a public URL is enough versus when you need dedicated nodes. It also covers the failure modes you will hit first — rate limits, missing archive or trace methods, and WebSocket gaps — and how to debug them.

Question 12

How do Solana NFT API providers ensure scalability and low-latency data?

Accepted Answer

Solana NFT APIs stay scalable and low-latency by combining indexed off-chain data with fast RPC access, then distributing load across caching layers, regional edge nodes, and dedicated node capacity. The practical result for developers is that metadata, ownership, and mint queries return quickly even when the underlying chain is busy.

This article explains the architecture behind those guarantees, shows how to evaluate an NFT data provider, and gives concrete RPC patterns for Solana using OnFinality endpoints so you can test latency and throughput yourself.
