Question 1

Base 公共 RPC 端点和独立性能指标：你应该评估什么？

Accepted Answer

Base 公共 RPC 端点便于原型设计和轻量读取，但它们是共享基础设施，不保证吞吐量、速率限制或可用性。独立性能指标可帮助你比较延迟、错误率和方法覆盖范围，但在投入生产之前，你应始终根据自身工作负载进行验证。

本文解释了如何阅读 Base 公共 RPC 端点列表、如何解读独立性能指标，以及何时从公共端点迁移到托管 RPC API 或专用 Base 节点。内容包括链设置、针对 OnFinality 公共 Base 端点的 curl 示例，以及实用的评估矩阵。

Question 2

BNB Smart Chain 应该使用什么 RPC URL？

Accepted Answer

BNB Smart Chain 主网的 RPC URL 是 https://bnb.api.onfinality.io/public，链 ID 为 56，原生代币为 BNB。测试网请使用 https://bnb-testnet.api.onfinality.io/public，链 ID 为 97，代币为 tBNB。本文介绍如何将网络添加到钱包、调用 JSON-RPC 方法，以及如何判断何时公共端点足够，何时需要专用节点基础设施。

Question 3

如何使用 RPC 和数据提供者访问 Sui 数据？

Accepted Answer

Sui 暴露了一个 JSON-RPC 接口，用于读取对象、交易、检查点和事件，您通过全节点端点连接到它。实际问题是使用哪个端点：用于探索的公共全节点、用于生产流量的托管 RPC API，还是当您需要隔离和可预测容量时的专用节点。

本参考指南将介绍 Sui RPC 接口、如何配置端点、如何使用 curl 和 JavaScript 查询数据，以及如何在公共、托管和专用选项之间做出选择。它还涵盖了常见的故障模式以及随着应用增长保持 Sui 数据访问稳定的运维检查。

Question 4

如何使用类似 Chainlist 的目录来查找支持的 RPC 网络和端点？

Accepted Answer

类似 Chainlist 的目录的存在是为了解决一个问题：将链 ID 映射到可用的 RPC 端点，以便钱包和 dApp 无需猜测即可连接。本文解释了这些目录的结构、如何读取它们公开的网络元数据，以及如何在你将其部署到生产环境之前验证端点。

它还涵盖了公共目录端点在哪些情况下不再足够、当列出的端点失败时应该检查什么，以及当你需要在多个链上获得可预测行为时，托管的 RPC API 或专用节点如何适用。

Question 5

BNB Smart Chain 公共 RPC URL：如何连接以及何时应该切换？

Accepted Answer

BNB Smart Chain 公共 RPC URL 是一个共享的 HTTPS 端点，允许钱包、脚本和 dApp 读取链上数据并提交交易，而无需运行节点。OnFinality 为 BNB Smart Chain 主网提供的公共端点是 https://bnb.api.onfinality.io/public，链 ID 为 56，原生代币为 BNB。

公共端点适用于原型设计、钱包设置和低流量读取。对于生产流量、归档查询或 WebSocket 订阅，团队通常会转向托管 RPC API 或专用节点，以便控制容量并避免共享端点的争用。

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

Solana NFT API 提供商如何确保可扩展性和低延迟数据？

Accepted Answer

Solana NFT API 通过将链下索引数据与快速 RPC 访问相结合，然后将负载分散到缓存层、区域边缘节点和专用节点容量上，从而保持可扩展性和低延迟。对开发者来说，实际结果是即使底层链繁忙，元数据、所有权和铸造查询也能快速返回。

本文解释了这些保证背后的架构，展示了如何评估 NFT 数据提供商，并给出了使用 OnFinality 端点的 Solana 具体 RPC 模式，以便您可以自行测试延迟和吞吐量。
