BNB Smart Chain RPC Endpoints & Dedicated Nodes

BNB Smart Chain (BSC) is an EVM-compatible blockchain known for fast block times and low transaction fees. It supports a wide range of decentralized applications in DeFi, gaming, NFTs, and more. OnFinality provides managed RPC endpoints and dedicated node infrastructure for BSC, enabling developers to build and scale production applications without the overhead of running their own nodes.

What is BNB Smart Chain?

BNB Smart Chain is a blockchain network that runs in parallel with BNB Beacon Chain. It is EVM-compatible, meaning Ethereum tools and smart contracts can be deployed with minimal changes. BSC uses a Proof of Staked Authority (PoSA) consensus mechanism, achieving 3-second block times and high throughput. The network is designed for high-volume applications and has a large ecosystem of wallets, DeFi protocols, and marketplaces.

Why Use OnFinality for BSC RPC?

OnFinality offers authenticated RPC endpoints for BSC, providing:

• Reliable access: Dedicated infrastructure with clear rate limits and no shared public congestion.
• Observability: Request analytics and usage metrics to monitor your application's performance.
• Scalability: A path from shared API endpoints to dedicated nodes for higher traffic demands.
• Advanced features: Support for archive data and trace API where available.

BSC RPC Endpoint Details

How to Connect to BSC via OnFinality

1. Create or sign in to your OnFinality account.
2. Select BNB Smart Chain from the supported networks list.
3. Create an API endpoint or deploy a dedicated node.
4. Test the endpoint using eth_blockNumber.
5. Monitor request usage, errors, and limits before moving critical traffic.

Public vs OnFinality RPC

Public RPC endpoints are suitable for lightweight testing but often have rate limits and no visibility. OnFinality endpoints are designed for teams that need stable, observable, and scalable infrastructure.
