Question 1

Asset Hub Polkadot: What It Is and How to Connect Your dApp

Accepted Answer

Asset Hub Polkadot is the system parachain that hosts assets, NFTs, and smart contracts for the Polkadot ecosystem. This article explains its role, key features, and how to connect your application using RPC endpoints, with practical examples and troubleshooting tips.

Question 2

Polkadot Network Migration: What's Changing and How It Affects Your RPC Endpoints?

Accepted Answer

The Polkadot Asset Hub Migration (AHM) moved core network functions—balances, staking, and governance—from the Relay Chain to the Asset Hub system parachain. For RPC users, this means that endpoints must now target Asset Hub for on-chain user data while the Relay Chain remains the entry point for consensus and cross-chain messages. Developers should verify their RPC provider supports both the Relay Chain and Asset Hub endpoints to avoid disruptions.

Question 3

How to Choose a Polkadot RPC Provider for Production dApps

Accepted Answer

Choosing the right Polkadot RPC provider is critical for production dApps, parachains, and cross-chain services. You need to evaluate endpoint reliability, archive data support, latency, and pricing to match your workload. OnFinality offers scalable Polkadot RPC endpoints with archive and trace support, dedicated node options, and transparent pricing to help you build and scale efficiently.

Question 4

Polkadot Validator: Build vs. Buy – Running a Node vs. Using an RPC Provider

Accepted Answer

A Polkadot validator secures the relay chain by staking DOT, validating parachain blocks, and participating in consensus. Running a validator requires significant hardware, administration, and a stake bond. For many developers and dApp operators, using a managed RPC provider eliminates the operational burden while still supporting the network indirectly.

Question 5

Asset Hub Migration: What Developers Need to Know About the Polkadot Relay Chain Transition

Accepted Answer

The Asset Hub migration moves core Polkadot functions—balances, staking, governance—from the Relay Chain to the Asset Hub system parachain. This guide explains the migration's impact on RPC endpoints, staking integrations, and developer workflows, with practical steps to update your infrastructure.

Question 6

Polkadot Nodes: A Developer's Guide to Running and Connecting to the Network

Accepted Answer

This guide covers everything developers need to know about Polkadot nodes: node types, how to run your own node, how to connect via RPC endpoints, and how to choose between self-hosted and provider-hosted nodes. Whether you're building a dApp, wallet, or infrastructure tool, you'll learn the practical steps to interact with the Polkadot network reliably.

Question 7

Polkadot Migration: What Developers Need to Know About the Relay Chain to Asset Hub Transition

Accepted Answer

# Polkadot Migration: What Developers Need to Know About the Relay Chain to Asset Hub Transition Polkadot is undergoing a major architectural shift: migrating core functions—balances, staking, and governance—from the Relay Chain to the Asset Hub system parachain. This transition, executed on November 4, 2025, aims to reduce Relay Chain bloat, enable faster upgrades, and pave the way for the JAM (Join-Accumulate Machine) protocol. For developers and infrastructure operators, understanding the migration's impact on RPC endpoints, account formats, and node operations is critical. This guide covers the technical implications, required actions, and how to ensure your dApps and services remain compatible. While end users required no action during the migration, developers must update RPC endpoints, verify account address formats, and test against Asset Hub's new runtime. OnFinality provides reliable Polkadot RPC API and dedicated node infrastructure to support your migration testing and production needs.

Question 8

What is a Polkadot node and how do you run one?

Accepted Answer

# What is a Polkadot node and how do you run one? A Polkadot node is a software client that connects to the Polkadot network, synchronizes blockchain data, and provides RPC endpoints for querying state, submitting transactions, and interacting with parachains. Running your own node gives you direct, trustless access to the network, but it requires significant hardware, storage, and ongoing maintenance. For many developers and dApps, using a managed RPC service like OnFinality offers a practical alternative with high availability and reduced operational overhead. This guide covers the different types of Polkadot nodes, how to set up and configure your own node, and when to consider a professional RPC provider for production workloads.

In practice, the useful question is not just whether an endpoint exists. Teams should check supported methods, traffic shape, monitoring, pricing, and the path from testing to production. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/polkadot after using this checklist so you can test the endpoint against your real methods.

Question 9

Polkadot RPC: A Complete Guide to Endpoints, Methods, and Providers

Accepted Answer

# Polkadot RPC: A Complete Guide to Endpoints, Methods, and Providers Polkadot's unique architecture as a Layer 0 relay chain with multiple parachains requires a nuanced understanding of its RPC infrastructure. Unlike single-chain networks, Polkadot exposes multiple RPC endpoints—one for the relay chain, one for each parachain (like Asset Hub), and optional Ethereum-compatible JSON-RPC endpoints for EVM-based tools. This guide covers everything you need to know about Polkadot RPC endpoints, JSON-RPC methods, and how to choose a reliable RPC provider for your dApp or infrastructure. Whether you are a developer building on Polkadot Hub, a parachain team needing dedicated node access, or an infrastructure buyer evaluating providers, this article provides practical, actionable information. We'll explore the available RPC methods, how to connect to different networks, and what to look for in a production-grade RPC service.

Question 10

Polkadot Asset Hub Migration: A Developer's Guide to the Relay Chain Transition

Accepted Answer

# Polkadot Asset Hub Migration: A Developer's Guide to the Relay Chain Transition The Polkadot Asset Hub migration, executed on November 4, 2025, moved core user-facing functions—balances, staking, governance—from the Relay Chain to the Asset Hub system parachain. This architectural shift reduces Relay Chain bloat, enables faster upgrades, and prepares the network for the JAM (Join-Accumulate Machine) era. For developers and infrastructure operators, understanding the migration's impact on RPC endpoints, transaction workflows, and node operations is critical. This guide covers what changed, how to update your integrations, and best practices for connecting to Asset Hub via reliable RPC infrastructure.

In practice, the useful question is not just whether an endpoint exists. Teams should check supported methods, traffic shape, monitoring, pricing, and the path from testing to production. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/polkadot after using this checklist so you can test the endpoint against your real methods.

Question 11

What should I know about Moonbeam RPC endpoints?

Accepted Answer

# What should I know about Moonbeam RPC endpoints? Moonbeam RPC endpoints matter because Web3 applications depend on stable endpoint access for reads, transactions, dashboards, and backend workflows. The right setup should match your workload, support the networks and testnets you need, make limits visible, and give you a scaling path when shared RPC is no longer enough. For Moonbeam builders, infrastructure leads, DeFi teams, wallets, games, analytics teams, and backend engineers, this is part of production architecture. A basic endpoint can be fine for a prototype, but production systems need predictable latency, clear request behavior, reliable support, and enough observability to debug incidents.
