Question 1

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 2

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 3

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

Accepted Answer

Optimism uptime refers to the availability of the OP Mainnet network and its core services, such as the public API, deposits, withdrawals, and transaction sequencing. While the official Optimism status page provides a high-level view, RPC endpoint reliability is what directly affects your dApp's performance. This article explains how to monitor Optimism uptime, what to look for in RPC providers, and how to build resilience into your application.

Question 4

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 5

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 6

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 7

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.

Question 8

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 9

What is the Arbitrum RPC endpoint and how do you use it?

Accepted Answer

Arbitrum RPC endpoints let wallets and dApps read and write data on Arbitrum One, Arbitrum Nova, and Arbitrum Sepolia. This guide covers the official public endpoints, chain settings, how to connect with curl or ethers, and how to choose a reliable provider for production.

Question 10

What is the SORA Network and how do you connect to it?

Accepted Answer

The SORA Network is a decentralized blockchain platform focused on creating a sovereign economic system. It uses the XOR token and a token bonding curve to manage supply, and it supports democratic governance and cross-chain interoperability. Developers can build on SORA using its Substrate-based chain, with tools like Polkaswap for DeFi. To interact with the network, you need a reliable RPC endpoint for reading data and submitting transactions. This guide explains what SORA is, how to choose an RPC provider, and how to get started with development.

Question 11

Avalanche API: What Should Developers Know About RPC, Data, and Node Access?

Accepted Answer

The Avalanche API is the set of interfaces developers use to read and write data on Avalanche's primary network and its Layer 1s. It includes JSON-RPC methods for the C-Chain, P-Chain, and X-Chain, plus higher-level data APIs for balances, transactions, and token metadata. Choosing the right API access depends on your workload: simple dApp calls can use public RPC endpoints, while production apps often need dedicated or managed infrastructure for reliability and rate limits.

Question 12

What is a MATIC RPC node and how do you connect to Polygon Mainnet?

Accepted Answer

A MATIC RPC node is a Polygon PoS endpoint exposed through JSON-RPC for reading chain state and broadcasting transactions. This reference covers Polygon Mainnet and Amoy chain settings, how to test endpoints with curl, and how to compare public RPCs against managed providers and dedicated nodes.

Use the checklist and chain IDs here to avoid the most common Polygon RPC mistakes, then decide when you need predictable throughput, WebSocket support, or archive methods for production workloads.
