Question 1

What Is Asset Hub and How Do You Connect to It?

Accepted Answer

Asset Hub is a system parachain on Polkadot and Kusama that hosts fungible tokens, NFTs, and other digital assets. It provides a dedicated environment for creating, managing, and transferring assets with low fees and high throughput. This article explains what Asset Hub is, how to connect your dApp to it, and how to choose the right RPC endpoint for your use case.

Question 2

SORA Blockchain and SORA Network: What Should Developers Know?

Accepted Answer

SORA is a Substrate-based blockchain network designed for a sovereign economic system, using the XOR token and a token bonding curve. It powers Polkaswap and supports democratic governance and cross-chain interoperability. This article explains what SORA is, how to connect to it via RPC, and what to consider when choosing infrastructure for production applications.

Question 3

Sonic RPC: Chain Settings, Endpoints, and Provider Selection

Accepted Answer

Sonic is a high-performance EVM Layer-1 blockchain with sub-second finality. This article covers Sonic mainnet and testnet chain settings, public and provider RPC endpoints, and how to choose a reliable RPC provider for production apps.

Question 4

What Is RWA Node Infrastructure and How Should You Build It?

Accepted Answer

RWA node infrastructure is the blockchain and data layer that supports tokenized real-world assets, including RPC endpoints, indexers, and node operations. This article explains the core components, how to evaluate infrastructure providers, and how to design a resilient stack for production RWA applications.

Question 5

Base RPC URL, Chain ID & Public Endpoint Setup

Accepted Answer

Base mainnet uses chain ID 8453 (0x2105) and the OnFinality public RPC endpoint https://base.api.onfinality.io/public. Use this URL for read-only testing, wallet setup, and initial dApp connections. For production traffic, authenticate with an OnFinality endpoint from the Base Hub and verify archive or Trace availability for your plan. Configure wallets with the Base explorer https://basescan.org and network name Base Mainnet. Example curl, ethers, and viem snippets are provided below, including wallet settings and code examples. Public endpoints are convenient but may be rate-limited and are not a substitute for a production RPC plan. Start with the public endpoint to validate your application flow, then move to a dedicated or authenticated endpoint before handling real users. For testnet work, use Base Sepolia chain ID 84532 and the endpoint https://base-sepolia.api.onfinality.io/public; testnet explorer is https://sepolia.basescan.org. See /networks/base for full Base network details and /rpc-assistant/rpc-providers-supporting-base-rpc for a provider comparison workflow.

Question 6

Mantle RPC: Chain Settings, Endpoints, and How to Choose a Provider

Accepted Answer

Mantle is an EVM-compatible Layer 2 rollup that uses a modular architecture with Ethereum for security and its own data availability layer. To connect wallets and dApps, you need the correct Mantle RPC endpoint, chain ID, and network settings. This page covers the essential chain settings, public and private endpoint options, and how to evaluate RPC providers for production workloads.

Question 7

Kusama Validator: Requirements, Setup, and Operational Tradeoffs

Accepted Answer

Learn what it takes to run a Kusama validator, from hardware and staking requirements to node setup and ongoing operations. Compare self-hosting with managed infrastructure and understand the risks, including slashing and commission. Get practical guidance for both new and experienced validators.

Question 8

How do I connect to the TON testnet?

Accepted Answer

The TON testnet is a public sandbox for building and testing smart contracts, wallets, and dApps without risking mainnet assets. This guide covers the key endpoints, faucets, and practical steps to get your testnet environment running, plus how to choose a reliable RPC provider for your development workflow.

Question 9

What are private RPC endpoints for dapps and when should you use them?

Accepted Answer

A private RPC endpoint is a unique URL with an API key that gives your dapp its own authenticated lane into a node provider's infrastructure. Unlike public endpoints shared by all users, private endpoints offer dedicated rate limits, better reliability, and observability. This guide explains the differences between public, private, and dedicated endpoints, and helps you decide which one your dapp needs.

Question 10

What is the xx network and how do developers interact with it?

Accepted Answer

The xx network is a quantum-resistant, privacy-focused blockchain with a decentralized mixnet. It uses a Substrate-based chain and offers RPC endpoints for developers. This article explains the network's architecture, how to connect via RPC, and what to consider when choosing infrastructure for building on xx.

Question 11

What is the Bittensor network and how do you connect to it?

Accepted Answer

Bittensor is a decentralized machine intelligence network where independent subnets produce digital commodities like compute, inference, and storage, and contributors earn TAO. This article explains the network's architecture, how to connect via RPC endpoints, and what to consider when choosing infrastructure for building on Bittensor.

Question 12

How do you check Arbitrum One uptime and what does it mean for your dApp?

Accepted Answer

Arbitrum One uptime is tracked on the official Arbitrum status page, which reports the health of core components like the sequencer, batch poster, validator, and feed. For dApp developers, understanding this uptime is important because it affects transaction finality, data availability, and RPC reliability. This guide explains how to read the status page, what uptime metrics matter, and how to choose RPC infrastructure that complements network health.
