Question 1

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 2

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 3

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 4

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 5

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.

Question 6

What Is Manta Atlantic and How Do You Connect to It?

Accepted Answer

Manta Atlantic is a zero-knowledge Layer 1 parachain on Polkadot focused on compliance identities and zkNFTs. Its Polkadot slot expires in August 2026, and Manta is directing users and assets to Manta Pacific, an EVM Layer 2 on Ethereum.

If you're a developer or infrastructure operator, you need to know how to reach Manta Atlantic RPC endpoints, which chain settings to use, and how to plan for the sunset. This reference page covers those essentials in a practical way.

Question 7

What is a TON endpoint and how do I choose one?

Accepted Answer

TON endpoints are HTTP and JSON-RPC bridge endpoints that let off-chain applications read blockchain data, query smart contracts, and submit transactions on The Open Network (TON). Because TON nodes speak ADNL rather than HTTP, an endpoint such as TON Center's API or a hosted RPC provider is the standard way for wallets, bots, and backends to talk to the network.

Choosing the right TON endpoint means checking whether you need mainnet or testnet access, deciding between TON Center API v2 (liteserver-backed) and v3 (indexed), verifying rate limits, and testing the endpoint before production. This guide covers endpoint options, sample requests, and a decision checklist for developers.

Question 8

What is a Starknet endpoint and how do you choose one?

Accepted Answer

A Starknet endpoint is the URL your application uses to send JSON-RPC requests to the Starknet mainnet or Sepolia testnet. It exposes methods for reading blocks, estimating fees, submitting transactions, and subscribing to events.

Choosing the right endpoint means checking network, RPC version, rate limits, archive data, and WebSocket support. Public endpoints are fine for prototyping; production dapps usually need a private API endpoint or a dedicated node from a provider like OnFinality.

Question 9

How do I mine Bittensor and keep my miner connected?

Accepted Answer

Bittensor is not mined with hash power. Miners run machine-learning workloads on subnets and are scored by validators, and the chain pays rewards in TAO. To start, pick a subnet, prepare hardware, register a miner with the Bittensor CLI, and keep the miner connected to the Subtensor chain through a reliable RPC endpoint. OnFinality provides a Bittensor Finney RPC endpoint and dedicated node options for miners who want managed chain access.

This guide walks through the decisions you need to make before buying hardware, the registration and setup steps, common failure modes, and how to evaluate whether a subnet is worth mining. You will also learn how to verify your Subtensor connection with a simple JSON-RPC request.

Question 10

What is the peaq network RPC and how do I connect to it?

Accepted Answer

The peaq network RPC is the API gateway between your application and the peaq blockchain, an EVM-compatible Layer-1 for DePIN and the machine economy. This reference covers chain ID 3338, PEAQ token details, public endpoints, JSON-RPC testing, and the provider criteria that matter before production.

Public peaq RPC endpoints are fine for prototyping, but machine-heavy workloads need a provider that handles WebSockets, log queries, and traffic spikes. OnFinality offers peaq RPC API and dedicated node options to keep your app stable as you scale.

Question 11

Where do you find Integritee RPC endpoints now?

Accepted Answer

Integritee is a Polkadot SDK-based privacy network that used Trusted Execution Environments to process sensitive data. The project announced a network shutdown on November 11, 2025, so public RPC endpoints may no longer be maintained and developers should verify network status before relying on them.

This article covers Integritee’s chain settings, standard Substrate JSON-RPC calls, and the criteria to use when evaluating RPC providers for active networks. It also includes a migration checklist for applications that depended on Integritee’s TEE-based privacy model.

Question 12

What is the Unichain RPC endpoint and how do I use it?

Accepted Answer

Unichain is an Ethereum L2 built on the OP Stack, and its RPC API follows standard Ethereum JSON-RPC. The mainnet chain ID is 130, and the network uses ETH as its native currency. You can start with a public endpoint such as https://unichain.api.onfinality.io/public for testing, then move to a managed RPC API for production.

Before integrating Unichain, verify WebSocket support, archive data, and rate limits with your chosen provider. OnFinality offers public Unichain RPC access, managed API plans, and dedicated node options. Check the supported networks and pricing pages for the latest details.
