Question 1

What should I know about the peaq network?

Accepted Answer

peaq is a Layer-1 blockchain purpose-built for Decentralized Physical Infrastructure Networks (DePIN) and machine economies. It provides the settlement layer, identity primitives, and token incentives that let connected devices, robots, and sensors transact autonomously. Developers interact with peaq through its Substrate-based RPC interface, which exposes standard JSON-RPC methods for reading chain state, submitting extrinsics, and subscribing to events.

If you are building on peaq, the practical question is how to get reliable RPC access without running your own validator or archive node. OnFinality provides managed RPC API and dedicated node infrastructure for peaq, so teams can connect wallets, indexers, and backend services to the network without operating the underlying hardware. This article covers peaq's architecture, how to connect, what to watch for in production, and when a managed provider makes sense.

Question 2

What is the peaq network blockchain, and how do you connect to it?

Accepted Answer

peaq is a Layer-1 blockchain built for machines, vehicles, robots, and other devices that need on-chain identity, payments, and data. Its EVM-compatible runtime means most Ethereum tooling works with only a network change, which is why developers usually start by connecting an RPC endpoint and reading chain state.

This page explains what peaq is, how to add it to a wallet, how to make JSON-RPC calls, and how to decide between a shared RPC API and dedicated node infrastructure as your workload grows.

Question 3

Polygon Mainnet RPC: How Do You Connect to Chain ID 137?

Accepted Answer

Polygon Mainnet is an EVM-compatible chain identified by chain ID 137, with POL as its native gas token. To connect, point your wallet or app at an HTTP or WebSocket RPC endpoint and confirm the chain ID matches 137 before sending transactions. OnFinality provides a public Polygon endpoint for testing and dedicated Polygon node infrastructure for production workloads that need consistent capacity.

Question 4

Base Network RPC: How Do I Connect and Which Endpoint Should I Use?

Accepted Answer

Base is an Ethereum Layer 2 built on the OP Stack, so its RPC interface is JSON-RPC compatible with Ethereum tooling. You connect by pointing a client at a Base endpoint with chain ID 8453, and most Ethereum libraries work with little or no change. The main decisions are which endpoint to use, how to handle rate limits, and how to keep requests reliable as traffic grows.

This page covers the Base mainnet and Base Sepolia chain settings, working request examples, common failure modes, and how to decide between a public endpoint, a managed RPC API, and a dedicated node. OnFinality provides Base RPC through its [RPC API service](/api-service) and [dedicated node](/dedicated-node) options.

Question 5

Sora Project and Sora Network: What Should Developers Know?

Accepted Answer

Sora is a decentralized finance network built on Substrate that aims to connect fiat and crypto through a regulated financial framework. This article explains the Sora project, its SORA network architecture, and how to access it via RPC endpoints for development.

Question 6

Avalanche Node RPC: How to Connect, Configure, and Debug Your Endpoints

Accepted Answer

Learn how Avalanche node RPC works, the difference between public and dedicated endpoints, and how to configure your dApp for C-Chain, X-Chain, and P-Chain. This guide covers chain settings, common JSON-RPC methods, and troubleshooting tips for production workloads.

Question 7

What is the TON Network RPC URL and How Do You Use It?

Accepted Answer

The TON Network RPC URL is the endpoint your dApp or bot uses to communicate with the TON blockchain. This article explains the official public endpoint, how to configure it in your code, and when you should consider a managed RPC service like OnFinality for production workloads.

Question 8

Polygon Network RPC: Endpoints, Chain Settings, and Debugging

Accepted Answer

Learn how to connect to the Polygon network via RPC, including the official OnFinality public endpoint, chain settings, and common troubleshooting steps. This guide covers JSON-RPC methods, WebSocket support, and how to choose between public, shared, and dedicated RPC infrastructure for your dApp.

Question 9

What is the Base network RPC endpoint and how do I use it?

Accepted Answer

The Base network RPC endpoint is the URL your dApp or wallet uses to communicate with the Base blockchain. OnFinality provides a public HTTPS endpoint at https://base.api.onfinality.io/public, which you can use to send JSON-RPC requests for reading data or submitting transactions. This article explains the endpoint, chain settings, how to configure your tools, and how to debug common issues.

Question 10

Avalanche RPC Node: Endpoint Settings, Provider Options, and Debugging

Accepted Answer

An Avalanche RPC node exposes the C-Chain's Ethereum-compatible JSON-RPC API, letting dApps read and write on-chain data. This article covers endpoint configuration, provider selection, and common failure modes to help you connect reliably in production.

Question 11

What is Crust Network and how does it provide decentralized storage?

Accepted Answer

Crust Network is a Substrate-based layer 1 blockchain that adds an incentive and service layer to IPFS, enabling decentralized, verifiable, and permanent storage. It offers an on-chain storage market, cross-chain interoperability, and tools for developers to integrate decentralized storage into dApps.

Question 12

Sonic Network RPC: Chain Settings, Endpoints, and Provider Selection

Accepted Answer

Sonic is a high-performance EVM Layer-1 blockchain with sub-second finality. This page covers the official Sonic network RPC settings, how to connect your wallet or dApp, and how to evaluate RPC providers for production workloads. We also explain when a managed or dedicated Sonic RPC endpoint is the right choice.
