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.
借助此 API，您可以：
- 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
您可以通过以下方式访问该 API：
- 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
