Question 1

Polkadot Asset Hub Migration: A Developer's Guide to the Relay Chain Transition

Accepted Answer

# Polkadot Asset Hub Migration: A Developer's Guide to the Relay Chain Transition The Polkadot Asset Hub migration, executed on November 4, 2025, moved core user-facing functions—balances, staking, governance—from the Relay Chain to the Asset Hub system parachain. This architectural shift reduces Relay Chain bloat, enables faster upgrades, and prepares the network for the JAM (Join-Accumulate Machine) era. For developers and infrastructure operators, understanding the migration's impact on RPC endpoints, transaction workflows, and node operations is critical. This guide covers what changed, how to update your integrations, and best practices for connecting to Asset Hub via reliable RPC infrastructure.

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/polkadot after using this checklist so you can test the endpoint against your real methods.

Question 2

What is HydraDX and how do you connect to it via RPC?

Accepted Answer

# What is HydraDX and how do you connect to it via RPC? HydraDX (now rebranded as Hydration) is a next-generation DeFi protocol built as a parachain on Polkadot. Its flagship product is the Omnipool, an innovative automated market maker (AMM) that combines all assets into a single trading pool, enabling capital-efficient swaps, single-sided liquidity provisioning, and reduced slippage. For developers and infrastructure buyers, connecting to the HydraDX network via a reliable RPC endpoint is essential for building dApps, querying on-chain data, or submitting transactions. This guide covers everything you need to know about HydraDX RPC endpoints, how to choose a provider, and best practices for integration.

Question 3

What Is the SORA Blockchain and How Do You Connect to It?

Accepted Answer

# What Is the SORA Blockchain and How Do You Connect to It? SORA is a blockchain platform designed to create a decentralized monetary system and economic infrastructure. Built on Hyperledger Iroha v3, it uses a single logical ledger, deterministic finality, and lane-based scaling to support payments, DeFi, CBDCs, and enterprise applications. The network is governed through democratic mechanisms and aims to provide a unified state for global markets. For developers and infrastructure buyers, connecting to SORA requires reliable RPC endpoints. This guide covers SORA’s architecture, how to interact with the network, and best practices for choosing RPC infrastructure. OnFinality offers public RPC endpoints and dedicated node services for SORA, enabling seamless integration without managing your own node.

Question 4

Sui gRPC Guide: Endpoints, Streaming & JSON-RPC Migration

Accepted Answer

Sui gRPC is the type-safe, Protocol Buffers-based RPC interface exposed by Sui full nodes. It is the recommended production path for reading chain state, executing transactions, and consuming real-time streams. OnFinality provides managed Sui gRPC and RPC infrastructure on mainnet and testnet; the current endpoint details are published on /networks/sui. In practice, you use grpcurl with a GRPC_ENDPOINT placeholder and authorization metadata from your provider, then target services by name. LedgerService covers checkpoints and consensus data, StateService covers object reads and balances, TransactionExecutionService provides ExecuteTransaction and SimulateTransaction workflows, and SubscriptionService offers SubscribeCheckpoints, SubscribeTransactions, and SubscribeEvents for streaming. Because JSON-RPC is being retired, teams should plan a migration by mapping legacy read, write, and subscription workflows to these gRPC services. Work from generated clients or proto definitions, not hand-built JSON calls. Test on testnet with the faucet at https://faucet.sui.io, keep mainnet separate, and verify stream reconnection and field masks before production.

Question 5

Gnosis RPC: Endpoints, Providers, and Best Practices

Accepted Answer

# Gnosis RPC: Endpoints, Providers, and Best Practices Gnosis Chain (formerly xDai) is an EVM-compatible L1 blockchain known for its stable gas token (xDAI) and low transaction costs. To interact with Gnosis Chain, developers and applications need a reliable RPC (Remote Procedure Call) endpoint. This guide covers everything you need to know about Gnosis RPC—from public endpoints and professional providers to best practices for production use. Whether you're building a dApp, running a validator, or simply connecting a wallet, choosing the right Gnosis RPC provider is critical for performance, reliability, and security. We'll explore the available options and help you make an informed decision.

Question 6

What should I know about the xx network?

Accepted Answer

# What should I know about the xx network? The xx network is a quantum-resistant layer 1 blockchain integrated with a decentralized mixnet (cMix) for private communications.

Question 8

How should developers evaluate RPC endpoints across Sepolia, Polygon, Solana Devnet, Base Sepolia, and peaq?

Accepted Answer

Choosing the right RPC endpoint is critical for dApp performance and reliability. This guide walks through key evaluation criteria—rate limits, chain IDs, testnet reliability, and when to upgrade to managed or dedicated infrastructure—across five popular networks: Ethereum Sepolia, Polygon, Solana Devnet, Base Sepolia, and peaq. Whether you're prototyping on a testnet or scaling on mainnet, understanding these factors helps you avoid bottlenecks and ensure smooth development.

In practice, the useful question is not just whether an endpoint exists. Teams should check Solana methods, devnet support, request patterns, and whether shared or dedicated access fits the workload. 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/eth-sepolia after using this checklist so you can test the endpoint against your real methods.

Question 9

What should I know about Arbitrum RPC endpoints?

Accepted Answer

# What should I know about Arbitrum RPC endpoints? Arbitrum RPC endpoints matter because Web3 applications depend on stable endpoint access for reads, transactions, dashboards, and backend workflows. The right setup should match your workload, support the networks and testnets you need, make limits visible, and give you a scaling path when shared RPC is no longer enough. For Arbitrum builders, infrastructure leads, DeFi teams, wallets, games, analytics teams, and backend engineers, this is part of production architecture. A basic endpoint can be fine for a prototype, but production systems need predictable latency, clear request behavior, reliable support, and enough observability to debug incidents.
