Question 3

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.

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 6

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 7

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.

If you already know the network you need, open /networks/efinity after using this checklist so you can test the endpoint against your real methods.

Question 9

What is a Polkadot node and how do you run one?

Accepted Answer

# What is a Polkadot node and how do you run one? A Polkadot node is a software client that connects to the Polkadot network, synchronizes blockchain data, and provides RPC endpoints for querying state, submitting transactions, and interacting with parachains. Running your own node gives you direct, trustless access to the network, but it requires significant hardware, storage, and ongoing maintenance. For many developers and dApps, using a managed RPC service like OnFinality offers a practical alternative with high availability and reduced operational overhead. This guide covers the different types of Polkadot nodes, how to set up and configure your own node, and when to consider a professional RPC provider for production workloads.

Question 10

What is TON RPC and how do you use it?

Accepted Answer

# What is TON RPC and how do you use it? The Open Network (TON) is a layer-1 blockchain designed for high scalability and deep integration with Telegram. Unlike EVM chains, TON uses a unique architecture with sharding and asynchronous smart contracts. To interact with TON from a web application, you need an RPC (Remote Procedure Call) endpoint that translates standard HTTP requests into the binary ADNL protocol used by TON nodes. This guide explains what TON RPC is, how to choose an endpoint, and best practices for reliable dApp connectivity.
