Question 1

Astar RPC Endpoints: Chain Settings, Public Nodes, and Production Considerations

Accepted Answer

Astar is a Polkadot parachain that offers EVM and Wasm smart contract support. This page lists public and provider-hosted Astar RPC endpoints, chain configuration details, and guidance for choosing an RPC provider for production dApps.

Question 2

Metis API: Chain Settings, RPC Methods, and Provider Selection

Accepted Answer

The Metis API refers to the JSON-RPC interface for the Metis Andromeda Layer 2 blockchain, an Ethereum-compatible rollup. This article covers chain configuration, essential RPC methods, how to connect wallets and dApps, and criteria for choosing a reliable RPC provider for production workloads.

Question 3

Enjin RPC: Endpoints, Chain Settings, and Developer Workflow

Accepted Answer

Enjin runs two Substrate-based chains: the Enjin Matrix Chain (application layer for NFTs and tokens) and the Enjin Relay Chain (consensus and security). Both use Substrate RPC (not EVM JSON-RPC), so developers need to use Polkadot.js or raw WebSocket/HTTPS calls. This article covers public and private RPC endpoints, chain settings, common RPC methods, and how to choose infrastructure for production dApps.

Question 4

Bifrost RPC Endpoints: Chain Settings, Provider Options, and Developer Setup

Accepted Answer

Bifrost is an EVM-compatible Layer 1 blockchain with a staking liquidity protocol. This article covers Bifrost mainnet and testnet RPC endpoints, chain settings, how to choose an RPC provider, and common developer setup steps.

Question 5

Phala RPC Endpoints: Chain Settings, Connection Guide, and Developer Resources

Accepted Answer

Phala Network is a Polkadot parachain that provides confidential smart contracts using Trusted Execution Environments (TEEs). To interact with Phala, developers need reliable RPC endpoints for reading on-chain data, submitting transactions, and deploying Phat Contracts. This article covers Phala RPC chain settings, how to connect, and what to consider when choosing an RPC provider.

Question 6

Kusama API: Endpoints, Methods, and How to Connect

Accepted Answer

The Kusama API provides JSON-RPC and WebSocket access to the Kusama canary network. This page covers available endpoints, common methods, connection examples, and how to choose between public, shared, and dedicated node infrastructure for your project.

Question 7

Binance Smart Chain Developer Guide for BNB Smart Chain

Accepted Answer

Binance Smart Chain, now officially BNB Smart Chain (BSC), is an EVM-compatible layer-1 blockchain with 3-second block times, mainnet chain ID 56, and testnet chain ID 97. Solidity developers can reuse Ethereum tooling—Hardhat, Foundry, OpenZeppelin, ethers.js, and web3.js—with minimal configuration changes. You need a reliable RPC endpoint: OnFinality provides EVM-compatible HTTPS and WebSocket RPC endpoints, Archive support, and trace/API access at https://bnb.api.onfinality.io/public for mainnet and https://bnb-testnet.api.onfinality.io/public for testnet. For testnet development use chain ID 97 and obtain tBNB from a faucet; for mainnet use chain ID 56 and BNB for gas. Deployment follows standard EVM flow: compile, test, estimate gas, send signed transaction, monitor receipt, and verify on BscScan. Handle nonces sequentially to avoid stuck or rejected transactions. Use testnet-to-mainnet promotion with security checks, secret management, contract verification, and rollback readiness. This guide covers Solidity tooling, chain configuration, contract deployment, finality, nonce/gas handling, RPC error diagnosis, and pre-mainnet operational checklists.

Question 8

Moonriver RPC: Endpoints, Configuration, and Best Practices

Accepted Answer

Moonriver is an Ethereum-compatible canary network on Kusama, ideal for testing dApps before deploying on Moonbeam. This guide covers Moonriver RPC endpoints, how to configure wallets and tools, and how to choose a reliable RPC provider for production use.

Question 9

What is the Acala Network and how do I connect to it?

Accepted Answer

The Acala Network is a decentralized finance (DeFi) hub built on Polkadot, offering cross-chain liquidity, liquid staking, and an EVM-compatible smart contract platform. This guide covers Acala's architecture, how to connect via RPC endpoints, and key considerations for developers building on Acala.

Question 10

Aleph Zero RPC: Endpoints, Setup, and Provider Selection

Accepted Answer

This guide covers Aleph Zero RPC endpoints for both mainnet and testnet, how to connect your dApp or wallet, and key criteria for selecting an RPC provider. Whether you are deploying on the EVM layer or the native Substrate chain, you will find practical endpoint references, configuration examples, and a decision checklist to evaluate reliability, latency, and pricing.

Question 11

Avalanche RPC: Endpoints, Chain IDs, and Provider Selection

Accepted Answer

This guide covers Avalanche RPC endpoints for the C-Chain, P-Chain, and X-Chain, including mainnet and Fuji testnet URLs, chain IDs, and how to choose a reliable RPC provider. It includes a decision checklist, evaluation criteria, and code examples to help developers integrate Avalanche RPC into their dApps.

Question 12

Kaia RPC: Endpoints, Providers, and Best Practices

Accepted Answer

This guide covers everything you need to know about Kaia RPC endpoints—from public JSON-RPC URLs to choosing a reliable provider for production. Learn how to connect to Kaia mainnet and Kairos testnet, evaluate RPC services, and avoid common pitfalls.
