Question 1

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 2

Dwellir vs Other RPC Providers: What Should You Compare?

Accepted Answer

Dwellir is a multi-chain RPC infrastructure provider that advertises access to over 150 blockchain networks. Developers commonly search for it when comparing API providers or looking for reliable HTTPS and WebSocket endpoints for Ethereum, Polkadot, Base, and other chains. This page helps you evaluate Dwellir's offerings against real production needs: chain coverage, archive data, failover behavior, and pricing transparency.

Rather than treating any single provider as a default, the decision comes down to your workload. If you need broad testnet coverage, predictable pricing, and simple failover, an RPC platform like OnFinality can be a strong alternative. Use the checklist below to compare Dwellir with other providers on the criteria that actually affect dApp reliability and cost.

Question 3

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 4

How do you choose a Stellar RPC provider for Soroban apps?

Accepted Answer

Stellar RPC gives you real-time access to Stellar network data for Soroban smart contracts, account balances, and transaction submission. Providers differ in network coverage, archive support, dedicated node access, and pricing, so the right choice depends on your app's workload.

This guide walks through what Stellar RPC is, the features to compare, and how to test provider performance before committing. It also covers common pitfalls like relying on RPC for historical data or using the wrong network for a given task.

Question 5

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 6

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 7

How reliable is Moonbeam RPC uptime and what should you monitor?

Accepted Answer

Moonbeam RPC uptime determines whether your dApp can read chain state, submit transactions, and stay responsive during traffic spikes. This page explains what uptime claims actually cover, how to verify them with your own monitoring, and how to choose RPC infrastructure that matches your reliability needs.

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

BNB Smart Chain Nodes: Full, Archive, Validator & RPC Nodes

Accepted Answer

BNB Smart Chain nodes are client instances that maintain a copy of BSC state, validate blocks, and serve JSON-RPC requests. Full nodes store current state and validate new blocks; archive nodes retain historical state for queries at any past block; fast nodes optimize throughput by skipping state verification; validator nodes participate in Proof of Staked Authority consensus. RPC nodes expose HTTP and WebSocket endpoints for wallets, dApps, and indexers. Most development teams need RPC access, not validator operations. You can run a node with the official BSC client or bsc-erigon, but self-hosting requires ongoing sync, storage, upgrades, backups, and monitoring. Managed RPC services remove that operational burden while providing production-grade endpoints, archive data, and failover. Use BNB Smart Chain mainnet chain ID 56 (0x38) and testnet chain ID 97 (0x61). OnFinality provides EVM-compatible HTTPS and WebSocket RPC, archive support, and public endpoints for mainnet and testnet. This guide covers node roles, self-hosting, archive workloads, validator vs. RPC operations, and a decision checklist for choosing infrastructure.

Question 10

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 11

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 12

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.
