Build on BNB Smart Chain with OnFinality RPC endpoints and dedicated node options for EVM-compatible applications. BNB Chain is widely used by DeFi, wallet, game, exchange, and backend teams that need fast access to balances, contracts, events, and transaction status.

BNB Chain RPC use cases

BNB Chain RPC endpoints use the EVM JSON-RPC interface, so Ethereum tooling such as ethers.js, web3.js, Hardhat, and Foundry can connect with familiar methods. The provider decision matters once your app depends on predictable reads, transaction submission, and event monitoring.

Common workloads include:

Wallet and dApp reads for balances, token data, and contract calls.
DeFi and trading tools that monitor receipts and logs.
Backend services that need stable request behavior during traffic bursts.
Analytics workflows that require historical data access.

OnFinality BNB Chain RPC features

Network: BNB Smart Chain Mainnet, Chain ID 56
Protocol: EVM JSON-RPC
Transport: HTTP and WebSocket
Advanced access: Archive support available
Dedicated nodes: Dedicated node options for production BSC workloads

Mainnet and testnet workflow

Use BNB Testnet to check contract deployments, wallet flows, and backend jobs before launch. Then repeat the same calls on mainnet and review request limits, monitoring, and scaling needs before moving user traffic.
