Question 8

What is Bittensor RPC and how do you connect to it?

Accepted Answer

# What is Bittensor RPC and how do you connect to it? Bittensor is a decentralized AI network built on a Substrate-based Layer 1 chain (Subtensor) with an optional Frontier EVM runtime. To interact with the network—whether querying subnet states, submitting inference requests, or deploying smart contracts—you need a Bittensor RPC endpoint. This guide explains the available RPC methods, network types (Finney mainnet and testnet), and how to choose a reliable provider. OnFinality provides public and dedicated Bittensor RPC endpoints for both Substrate and EVM interfaces, supporting developers building on Bittensor’s AI subnets.

In practice, the useful question is not just whether an endpoint exists. Teams should check supported methods, traffic shape, monitoring, pricing, and the path from testing to production. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/bittensor-finney after using this checklist so you can test the endpoint against your real methods.

Question 9

What is Pichiu Network and How to Connect via RPC?

Accepted Answer

# What is Pichiu Network and How to Connect via RPC? Pichiu Network is a blockchain project that focuses on decentralized oracle services, enabling smart contracts to securely interact with off-chain data. Built on Substrate, it provides a robust infrastructure for data feeds and cross-chain communication. For developers building on Pichiu, reliable RPC endpoints are essential for querying on-chain data and submitting transactions. This guide covers the essentials of connecting to Pichiu Network using RPC endpoints, including public and dedicated node options. Whether you are a dApp developer or a validator, understanding how to configure your RPC connection ensures optimal performance and availability for your applications.

In practice, the useful question is not just whether an endpoint exists. Teams should check supported methods, traffic shape, monitoring, pricing, and the path from testing to production. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/pichiu-oracle after using this checklist so you can test the endpoint against your real methods.

Question 10

TON Testnet: Complete Developer's Guide to RPC Endpoints, Faucets, and Setup

Accepted Answer

# TON Testnet: Complete Developer's Guide to RPC Endpoints, Faucets, and Setup The TON testnet is a public sandbox environment for The Open Network, allowing developers to deploy smart contracts, test dApps, and experiment with TON features without using real TON tokens. This guide covers everything you need to get started: RPC endpoints, faucets, block explorers, and best practices for reliable testnet infrastructure. Whether you're building a wallet, a DeFi protocol, or an NFT marketplace, the TON testnet is your first step to production-ready development. OnFinality provides dedicated and shared RPC endpoints for the TON testnet, offering high reliability and scalability for your testing workflows. With support for both HTTP and WebSocket connections, you can integrate seamlessly into your development pipeline.

In practice, the useful question is not just whether an endpoint exists. Teams should check testnet endpoint access, chain settings, faucet assumptions, staging checks, and the path to mainnet. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/ton after using this checklist so you can test the endpoint against your real methods.

Question 11

Ethereum RPC Infrastructure: Public, Private, Archive & Dedicated Nodes

Accepted Answer

Ethereum RPC infrastructure spans public endpoints, shared managed services, private managed nodes, and dedicated nodes. Public endpoints are free but rate-limited and unsuitable for production. Shared managed RPC offers better reliability and managed operations while still pooling resources across tenants. Private managed nodes provide isolated capacity with predictable performance, while dedicated nodes give full control over node configuration, regions, and failover. The right choice depends on workload: read-heavy dashboards may work on shared RPC, transaction-heavy bots or indexers may need dedicated capacity, and historical queries require archive nodes. Full nodes keep recent state, archive nodes retain all historical state for any block height. Trace and Debug APIs add CPU-heavy methods like debug_traceTransaction, which can affect latency and cost. Production teams should evaluate scaling path, geographic routing, observability, failover behavior, and upgrade operations before committing. Plan by workload, not vendor label, and verify current limits and features on the Ethereum network page.

Question 12

Polkadot Migration: What Developers Need to Know About the Relay Chain to Asset Hub Transition

Accepted Answer

# Polkadot Migration: What Developers Need to Know About the Relay Chain to Asset Hub Transition Polkadot is undergoing a major architectural shift: migrating core functions—balances, staking, and governance—from the Relay Chain to the Asset Hub system parachain. This transition, executed on November 4, 2025, aims to reduce Relay Chain bloat, enable faster upgrades, and pave the way for the JAM (Join-Accumulate Machine) protocol. For developers and infrastructure operators, understanding the migration's impact on RPC endpoints, account formats, and node operations is critical. This guide covers the technical implications, required actions, and how to ensure your dApps and services remain compatible. While end users required no action during the migration, developers must update RPC endpoints, verify account address formats, and test against Asset Hub's new runtime. OnFinality provides reliable Polkadot RPC API and dedicated node infrastructure to support your migration testing and production needs.
