Question 1

What is Pichiu Network and How to Connect via RPC?

Accepted Answer

# What is Pichiu Network and How to Connect via RPC? Pichiu Network is a blockchain project that focuses on decentralized oracle services, enabling smart contracts to securely interact with off-chain data. Built on Substrate, it provides a robust infrastructure for data feeds and cross-chain communication. For developers building on Pichiu, reliable RPC endpoints are essential for querying on-chain data and submitting transactions. This guide covers the essentials of connecting to Pichiu Network using RPC endpoints, including public and dedicated node options. Whether you are a dApp developer or a validator, understanding how to configure your RPC connection ensures optimal performance and availability for your applications.

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/pichiu-oracle after using this checklist so you can test the endpoint against your real methods.

Question 2

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 4

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.

Question 5

What is TON RPC and how do you use it?

Accepted Answer

# What is TON RPC and how do you use it? The Open Network (TON) is a layer-1 blockchain designed for high scalability and deep integration with Telegram. Unlike EVM chains, TON uses a unique architecture with sharding and asynchronous smart contracts. To interact with TON from a web application, you need an RPC (Remote Procedure Call) endpoint that translates standard HTTP requests into the binary ADNL protocol used by TON nodes. This guide explains what TON RPC is, how to choose an endpoint, and best practices for reliable dApp connectivity.

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

Polygon RPC Providers & Nodes: Public, Managed & Dedicated

Accepted Answer

Polygon RPC providers expose JSON-RPC endpoints that let dApps, wallets, and backend services read chain data, send transactions, and interact with smart contracts. Polygon PoS mainnet uses chain ID 137, while Amoy testnet uses 80002. This guide compares public, shared managed, and dedicated access options without vendor rankings. Instead, evaluate providers by production fit: method coverage, rate limits, WebSocket reliability, monitoring, archive and Trace support, and the ability to move from shared to dedicated infrastructure when needed. Public endpoints suit prototyping and low-traffic development; shared managed plans add higher limits and operational visibility; dedicated nodes offer isolated capacity and custom configuration for high-volume or latency-sensitive workloads. Bor and Heimdall serve different layers—Bor handles execution and JSON-RPC, while Heimdall manages consensus and checkpoints. Understanding these roles helps you troubleshoot and plan capacity. Use the decision framework below to match infrastructure to your actual workload, test with Amoy, and review current plan details before production.

Question 11

What is Stellar RPC and how do you use it?

Accepted Answer

Stellar RPC (Remote Procedure Call) is the standard interface for interacting with the Stellar blockchain network. It allows developers to query ledger data, submit transactions, and manage accounts programmatically. Stellar's RPC API is distinct from Ethereum-compatible JSON-RPC; it uses a custom Horizon API built on RESTful principles, but also supports a Soroban RPC for smart contract interactions. This guide covers the essential endpoints, authentication, and best practices for building on Stellar. Whether you are building a payment application, a decentralized exchange, or a smart contract on Soroban, reliable RPC access is critical. OnFinality provides managed Stellar RPC endpoints with high availability and low latency, supporting both Horizon and Soroban RPC 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/stellar after using this checklist so you can test the endpoint against your real methods.

Question 12

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.
