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.
透過此 API，您可以：
- 執行所有標準的以太坊 JSON-RPC 方法（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
- 透過 WebSocket 連線訂閱即時事件
您可以透過以下方式存取 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
