Question 1

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 2

What is the Abstract chain RPC endpoint and how do I connect to it?

Accepted Answer

Abstract is an EVM-compatible zero-knowledge rollup built on zkSync's ZK Stack for consumer applications. The mainnet HTTP RPC endpoint is https://api.mainnet.abs.xyz with chain ID 2741, and the WebSocket endpoint is wss://api.mainnet.abs.xyz/ws. The testnet uses chain ID 11124 and https://api.testnet.abs.xyz, with a Sepolia-based explorer at sepolia.abscan.org.

Public endpoints are fine for testing and light wallet use, but production dApps should evaluate throughput, archive data, WebSocket stability, and failover behavior. OnFinality provides managed Abstract RPC access and dedicated node options through its API service, so teams can move from a public endpoint to infrastructure with predictable capacity.

Question 3

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 4

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 5

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 6

What is the peaq mainnet RPC endpoint?

Accepted Answer

peaq mainnet is an EVM-compatible Layer-1 blockchain built on Substrate and connected to the Polkadot ecosystem. Its RPC lets wallets and applications read chain data, submit transactions, and subscribe to events using chain ID 3338 and the native PEAQ token.

This article covers peaq mainnet chain settings, JSON-RPC examples, endpoint selection, and common debugging issues so you can add peaq support to your app without guessing.

Question 7

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 8

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 9

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.

Question 10

What is the Moonbeam RPC endpoint and how do you connect to it?

Accepted Answer

A Moonbeam RPC endpoint is a URL that lets Ethereum-compatible wallets and dApps send JSON-RPC requests to the Moonbeam parachain on Polkadot. It uses standard Ethereum methods plus Moonbeam-specific extensions, with chain ID 1284 and GLMR as the native token.

Developers use these endpoints for reads, transactions, event subscriptions, and indexing. This page covers the network settings you need, how to test an endpoint with curl, and what to evaluate when choosing a provider for production workloads.

Question 11

BNB Smart Chain RPC Endpoint and Chain Settings

Accepted Answer

BNB Smart Chain (BSC) is an EVM-compatible network with mainnet chain ID 56 (hex 0x38) and testnet chain ID 97 (hex 0x61). To connect, you need an RPC URL, the correct chain ID, currency symbol BNB (tBNB on testnet), and a block explorer. Official public mainnet endpoints, such as https://bsc-dataseed.bnbchain.org, are available for testing and light use, while OnFinality offers a public mainnet endpoint at https://bnb.api.onfinality.io/public with EVM-compatible HTTPS and WebSocket RPC, archive support, and trace/API access. Before trusting any endpoint, send an eth_chainId request: a mainnet response returns 0x38, and testnet returns 0x61. Using the wrong chain ID is a common cause of rejected transactions and can lead to funds loss if you connect to the wrong network. Public endpoints often have rate limits and may disable eth_getLogs, so production applications should evaluate managed endpoints with predictable throughput, archive data, and WebSocket support. This guide covers wallet configuration, curl, ethers, and viem setup, common endpoint failures, and a path to OnFinality's BNB network hub and testnet guide.

Question 12

What are the Moonbeam RPC endpoints and which provider should I use?

Accepted Answer

Moonbeam Mainnet uses chain ID 1284 (0x504) with GLMR as the native token. Public RPC endpoints include https://rpc.api.moonbeam.network, https://moonbeam.drpc.org, and https://moonbeam.api.onfinality.io/public. For production apps, evaluate providers based on reliability, scalability, WebSocket support, and archive data access. OnFinality offers scalable RPC API and dedicated nodes for Moonbeam.
