Question 1

What is the BNB RPC name and how do you configure it?

Accepted Answer

The BNB RPC name is the network label and chain identifier your wallet or library uses to connect to BNB Smart Chain. In practice this means the chain name (BNB Smart Chain), the RPC URL, the chain ID (56 for mainnet, 97 for testnet), the native currency symbol (BNB or tBNB), and the block explorer URL. Getting these values right is what stops "wrong network" and "unknown chain" errors.

This page gives you the exact mainnet and testnet settings, shows how to add the network in MetaMask and in code with ethers or viem, and explains how to pick an RPC endpoint that holds up under real traffic. OnFinality provides BNB Chain RPC API access and dedicated nodes when you need more control than a public endpoint offers.

Question 2

What are the hardware and software requirements for running a BNB Chain node?

Accepted Answer

Running a BNB Smart Chain node requires meeting specific hardware baselines for CPU, RAM, disk, and network bandwidth, plus choosing between full, archive, and validator node configurations. The requirements differ significantly depending on whether you are syncing a full node, serving historical data, or validating blocks. For teams that need BNB Chain RPC access without operating the hardware, OnFinality provides managed RPC API and dedicated node infrastructure that removes the operational burden.

Question 3

What is a Binance Smart Chain archive node and when do you need one?

Accepted Answer

A Binance Smart Chain (BNB Smart Chain) archive node keeps the full historical state of the chain, so you can query balances, storage slots, and contract state at any past block height. Standard full nodes prune old state, which is why historical queries fail against them. Archive access is essential for analytics, tax and accounting tools, indexers, and any backend that needs to reconstruct what happened at a specific block. You can connect to an archive-capable endpoint through OnFinality's RPC API or run a dedicated archive node when your workload needs consistent historical throughput.

Question 4

BNB Smart Chain RPC: Endpoint Settings, Chain ID, and Debugging

Accepted Answer

BNB Smart Chain (BSC) exposes an EVM-compatible JSON-RPC interface, so most Ethereum tooling works after you point it at a BSC endpoint and set chain ID 56. This page covers the endpoint format, wallet and library configuration, the methods that matter for BSC apps, and how to debug the failures you are most likely to hit.

You can start against the public OnFinality endpoint for quick tests, then move to a managed RPC API or a dedicated node when you need predictable throughput, archive access, or WebSocket subscriptions for production traffic.

Question 5

What is the Binance Beacon Chain explorer and how do you query it?

Accepted Answer

The Binance Beacon Chain was the staking and governance layer of the BNB Chain ecosystem, running alongside BNB Smart Chain before the two were merged in the 2024 opBNB-era consolidation. Its explorer let you inspect validators, delegations, and cross-chain activity. Today, most developers interact with the BNB Chain ecosystem through BNB Smart Chain RPC endpoints instead.

This page explains what the Beacon Chain explorer showed, why it matters for historical lookups, and how to move to the BNB Smart Chain RPC workflow that OnFinality supports for production apps. You can connect to a public endpoint for testing or run dedicated node infrastructure for heavier workloads.

Question 6

RPC BNB: How Do You Connect to BNB Smart Chain and Pick the Right Endpoint?

Accepted Answer

This page explains what an RPC endpoint for BNB Smart Chain (BNB Chain) is, how to connect to mainnet and testnet, and how to choose between public, shared, and dedicated infrastructure. It covers chain settings, a working JSON-RPC example, WebSocket support, and the failure modes developers hit most often. Use it as a reference when wiring a wallet, backend service, or indexer to BNB Chain.

Question 7

What is a Smart Chain RPC URL and how do I connect to BNB Smart Chain?

Accepted Answer

A Smart Chain RPC URL is the HTTP or WebSocket endpoint your wallet, dApp, or backend uses to read BNB Smart Chain state and broadcast transactions. It carries JSON-RPC calls such as eth_blockNumber, eth_getBalance, and eth_sendRawTransaction to a node that is synced with the network.

This page covers the BNB Smart Chain mainnet and testnet settings you need for wallet configuration, gives a working curl and JavaScript example, and explains when a public endpoint is enough versus when a managed RPC API or dedicated node is the better fit for production traffic.

Question 8

BNB RPC List: Which Endpoints Should Your App Connect To?

Accepted Answer

A BNB RPC list is only useful if you know which endpoint type fits your workload. This page breaks BNB Smart Chain endpoints into public, managed, and dedicated categories, then shows the chain settings, request formats, and failure modes you need before wiring anything into production.

You get the exact mainnet and testnet connection details, a curl and viem example, and a short evaluation path for deciding when a shared endpoint is enough and when a dedicated BNB node is the better fit.

Question 9

BNB Smart Chain Testnet RPC: Chain Settings, Faucet, and Debugging

Accepted Answer

BNB Smart Chain Testnet (chain ID 97) is where you validate contracts, wallets, and indexers before touching mainnet. This page gives you the exact network settings, a working public endpoint, faucet guidance, and the failure modes that waste the most developer time. You will also find a short checklist for deciding when a shared public endpoint is enough and when a dedicated node is the better fit.

Question 10

BNB Chain Testnet RPC Endpoint: Chain Settings, Faucet, and Debugging

Accepted Answer

This page explains how to connect to the BNB Chain Testnet (BSC Testnet) using an RPC endpoint. You'll find the official OnFinality public endpoint, chain settings, faucet instructions, and common debugging tips for building and testing dApps on testnet.

Question 11

BNB Smart Chain Node: What It Is and How to Connect Reliably

Accepted Answer

A BNB Smart Chain node is a client that stores BSC state and serves JSON-RPC requests. You can run one yourself or use a managed RPC provider. This page explains node types, how to connect, and how to choose infrastructure that matches your workload.

Question 12

What is a BNB Chain node and how do you run or connect to one?

Accepted Answer

A BNB Chain node is a client that maintains a full copy of BNB Smart Chain and serves JSON-RPC requests for reading chain state, sending transactions, and listening to events. You can run your own node, use a public endpoint, or rely on a managed RPC provider like OnFinality for production workloads.
