Question 1

What are the Moonbeam RPC endpoints and which provider should I use?

Accepted Answer

Moonbeam Mainnet uses chain ID 1284 (0x504) with GLMR as the native token. Public RPC endpoints include https://rpc.api.moonbeam.network, https://moonbeam.drpc.org, and https://moonbeam.api.onfinality.io/public. For production apps, evaluate providers based on reliability, scalability, WebSocket support, and archive data access. OnFinality offers scalable RPC API and dedicated nodes for Moonbeam.

Question 2

What should I know about SORA network RPC endpoints?

Accepted Answer

SORA is a blockchain monetary system built on Substrate, offering a decentralized framework for digital money. Developers building on SORA need reliable RPC endpoints for reading chain data, submitting transactions, and interacting with the Polkaswap DEX. This guide covers chain settings, public and dedicated RPC options, faucet details, and common debugging tips for mainnet and Taira testnet.

Question 3

Kava API Endpoints: What Developers Need to Know

Accepted Answer

Kava combines Cosmos SDK and Ethereum Virtual Machine (EVM) compatibility, offering multiple API interfaces: Tendermint RPC, EVM JSON-RPC, REST API, and WebSocket endpoints. This article explains the available endpoint types, how to connect, and what to evaluate when choosing a Kava API provider for production dApps.

Question 4

Asset Hub Kusama RPC Endpoints: Chain Settings, Faucet, and Debugging Tips

Accepted Answer

Asset Hub Kusama is the Kusama system parachain for hosting and transferring fungible and non-fungible assets. This article provides the RPC endpoints, chain settings, faucet information, and common debugging tips to help developers connect and build on Asset Hub Kusama, whether using public endpoints or dedicated node infrastructure.

Question 5

What Are the Kaia RPC Endpoints and How Do You Connect to Kaia?

Accepted Answer

Kaia is an enterprise-grade L1 blockchain with mainnet (Cypress) and testnet (Kairos). Developers can use public RPC endpoints for testing, but production apps often need a dedicated provider for reliability and rate limits. This guide covers available endpoints, provider options, and how to choose the right infrastructure for your Kaia project.

Question 6

peaq RPC Endpoint: Chain Settings, Faucet, and Debugging

Accepted Answer

peaq is a Polkadot-based Layer-1 blockchain tailored for Decentralized Physical Infrastructure Networks (DePIN) and the machine economy. To interact with the peaq network, developers need reliable RPC endpoints for reading on-chain data, submitting transactions, and monitoring machine identities. This article covers essential chain settings, how to evaluate RPC providers, common debugging tips, and recommended next steps for production deployments.

Question 7

What are the Celo RPC endpoints for mainnet and testnet?

Accepted Answer

Celo RPC endpoints let developers connect to the Celo blockchain. Mainnet chain ID is 42220, testnet (Celo Sepolia) chain ID is 11142220. Free public endpoints exist but are rate-limited; for production apps, consider a dedicated RPC provider like OnFinality.

Question 8

BSC API: JSON-RPC Methods, WebSocket, Finality & Examples

Accepted Answer

The BSC API is the JSON-RPC interface for BNB Smart Chain (BSC), an EVM-compatible network with mainnet chain ID 56 and testnet chain ID 97. Developers use standard Ethereum-style methods such as eth_blockNumber, eth_getBalance, eth_call, eth_getLogs, and eth_sendRawTransaction, plus BSC-specific finality methods like eth_getFinalizedHeader, eth_getFinalizedBlock, and eth_newFinalizedHeaderFilter. OnFinality exposes EVM-compatible HTTPS and WebSocket endpoints for BSC, including a public mainnet endpoint at https://bnb.api.onfinality.io/public and a public testnet endpoint at https://bnb-testnet.api.onfinality.io/public. For production workloads, use your OnFinality API key and private endpoint from the dashboard. This page covers method categories, finality behavior, WebSocket subscriptions, and curl/viem examples. Use the official BNB public endpoints only for testing: the public list rate limit is 10K/5min and eth_getLogs is disabled on listed mainnet endpoints; OnFinality endpoints are managed separately and should be validated against your plan.

Question 9

What Are Avalanche Nodes and When Should You Use Them?

Accepted Answer

Avalanche nodes are the backbone of the Avalanche network, handling transaction relay, block production, and consensus. They come in several types: validators, full nodes, archive nodes, and state-sync nodes, each with different data retention and resource needs. This article explains node roles, hardware requirements, and helps you decide whether to run a node yourself or use a managed RPC service like OnFinality.

Question 10

Polygon Blockchain API: JSON-RPC Methods, WebSocket & Examples

Accepted Answer

The Polygon blockchain API is the Ethereum-compatible JSON-RPC interface used to interact with Polygon PoS mainnet (chain ID 137) and Polygon Amoy testnet (chain ID 80002). Because Polygon PoS remains EVM-compatible, the execution layer accepts standard Ethereum methods such as eth_call, eth_getLogs, eth_sendRawTransaction, eth_getTransactionReceipt, and eth_estimateGas. Developers send these requests over HTTP for request/response workloads, or open a WebSocket connection for subscriptions such as newHeads, logs, and pending transactions. Archive and trace methods may be available depending on the plan; verify current limits and availability on the Polygon network page before relying on them. For production, replace public endpoints with a dedicated node or managed RPC cluster, test contracts on Amoy first, and handle nonce, gas, and receipt polling carefully. The examples below show minimal curl and ethers.js workflows for reading data, submitting transactions, and subscribing to block headers.

Question 11

What are the Bittensor RPC URLs for mainnet, lite, and testnet?

Accepted Answer

Bittensor offers multiple RPC endpoints for different network tiers: Finney (mainnet) at `wss://entrypoint-finney.opentensor.ai:443`, Lite (EVM-compatible) at `https://lite.chain.opentensor.ai`, and testnet at `https://test.chain.opentensor.ai`. Developers can also use managed providers like OnFinality for reliable dedicated or public endpoints. This guide lists official URLs, chain IDs, and configuration steps for wallets and dApps.

Question 12

Ethereum Blockchain API: JSON-RPC Methods, WebSocket & Examples

Accepted Answer

The Ethereum blockchain API is the JSON-RPC interface that lets applications read from and write to the Ethereum network without running a local node. It exposes core methods such as eth_call for read-only contract simulation, eth_getLogs for filtered event history, eth_sendRawTransaction for broadcasting signed transactions, eth_getTransactionReceipt for confirming inclusion, and eth_estimateGas for gas planning. Every request carries jsonrpc, method, params, and id fields; the response returns a result object or a JSON-RPC error. Access is available over HTTPS for standard request/response patterns and WebSocket for push-based subscriptions like newHeads, logs, and pending transactions. Optional Trace and Debug APIs provide deeper execution tracing but are separate entry points from core methods and not universally available. For production, connect through a managed endpoint such as OnFinality, verify archive and regional access on the Ethereum network page, and keep mainnet chain ID 1 distinct from Sepolia chain ID 11155111. Sign transactions locally and submit via eth_sendRawTransaction; use eth_call for reads and eth_estimateGas before sending.
