BNB Smart Chain RPC
What is BNB Smart Chain?
BNB Smart Chain (BSC) is an EVM-compatible blockchain developed by Binance. BSC provides smart contract functionality through the Ethereum Virtual Machine. BSC uses a Proof of Staked Authority (PoSA) consensus mechanism that combines elements of Proof of Authority and Delegated Proof of Stake. The network implements BEP-20 as its token standard (equivalent to ERC-20) and supports additional standards like BEP-721 for NFTs.
Interacting with BNB Smart Chain
The BNB Smart Chain provides full compatibility with Ethereum's JSON-RPC interface, allowing developers to interact with BSC using standard Ethereum tooling. Since BSC maintains EVM equivalence, existing Solidity contracts can deploy directly without code changes.
With this API, you can:
- Execute all standard Ethereum JSON-RPC methods (eth_call, eth_sendTransaction, eth_getBalance)
- Deploy and interact with BEP-20 tokens and smart contracts
- Query blockchain state including blocks, transactions, receipts, and event logs
- Subscribe to real-time events via WebSocket connections
You can access the API by:
- Running a local BSC node (Geth-based BSC client)
- Using a hosted provider such as a Quicknode BNB Smart Chain endpoint, which provides low-latency access to both mainnet and testnet with archive data support
