Question 1

What is a Moonbeam node and when should you run one?

Accepted Answer

A Moonbeam node is a full client for the Moonbeam network, an Ethereum-compatible parachain on Polkadot. Running one gives you local RPC access, block production, and deeper control, but it requires significant hardware and maintenance. For most dApps, a managed RPC service like OnFinality offers reliable endpoints without the operational overhead.

Question 2

Klaytn API: What should developers know about RPC, KAS, and node infrastructure?

Accepted Answer

Klaytn, now rebranded as Kaia, is an EVM-compatible Layer 1 blockchain. Developers interact with it through JSON-RPC endpoints, the Klaytn API Service (KAS) for higher-level REST APIs, or dedicated node infrastructure. This guide covers the differences, how to connect, and what to evaluate when choosing an API provider.

Question 3

What Is the SORA Project and How Does the SORA Blockchain Work?

Accepted Answer

The SORA project is a blockchain initiative focused on decentralized finance and monetary systems, evolving from a Polkadot parachain into SORA Nexus, a Hyperledger Iroha 3-based network. This article explains the SORA blockchain's architecture, its transition to SORA v3, and how developers can connect to it via RPC endpoints.

Question 4

How to Mine TAO on Bittensor: A Practical Guide for Developers

Accepted Answer

Mining TAO on Bittensor means running a miner on a subnet that produces a digital commodity—such as inference, compute, or storage—and getting rewarded in TAO. This guide explains the roles of miners, validators, and subnets, how to choose a subnet, and the practical steps to register and run a miner, including the RPC endpoints you'll need to interact with the Finney network.

Question 5

Optimism API: What It Is and How to Use It for OP Mainnet

Accepted Answer

The Optimism API is the set of JSON-RPC endpoints that let applications read and write data on OP Mainnet, an Ethereum Layer 2 built with optimistic rollups. It follows the same JSON-RPC standard as Ethereum, so you can use familiar libraries like ethers or viem to interact with the chain. This article explains what the Optimism API is, how it differs from Ethereum's API, and how to choose the right endpoint provider for your project.

Question 6

What is a BNB node and when should you run one?

Accepted Answer

A BNB node is a client that stores the BNB Smart Chain state and processes transactions. Running one gives you direct access to the chain, but it requires significant hardware and maintenance. For most applications, a managed RPC service like OnFinality provides a more practical way to interact with BNB Chain without the operational overhead.

Question 7

What Is the SORA Blockchain Project and How Do You Build on It?

Accepted Answer

The SORA blockchain project is a decentralized monetary system and DeFi platform built on Substrate, designed to create a supranational economic framework. It includes the XOR token, the Polkaswap DEX, and the TBC (Token Bonding Curve). This article explains the project's architecture, how to connect to the SORA network via RPC endpoints, and how to choose the right infrastructure for building applications.

Question 8

What Is Mangata X and How Do You Connect to Its RPC?

Accepted Answer

Mangata X is a community-owned, omnichain decentralized exchange (DEX) built as a Substrate-based app-chain on Kusama, designed to minimize MEV and enable cross-chain swaps. This page explains what Mangata X is, how to connect to its RPC endpoints, and how to evaluate infrastructure options for building on it.

Question 9

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 10

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 11

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 12

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.
