BNB Chain Explorer

WHAT IT DOES

BNB Chain Explorer is a read-only blockchain analytics tool designed specifically for the BNB Smart Chain ecosystem. It provides comprehensive visibility into on-chain activity including native BNB transactions, BEP-20 token transfers, contract interactions, wallet balances, and detailed transaction receipts. The tool retrieves full transaction details with gas costs calculated using effectiveGasPrice (not the pre-EIP-1559 gasPrice cap), logs BEP-20 transfer events from transaction receipts, and displays token movement alongside native value transfers. For addresses, it shows BNB balance and aggregates recent BEP-20 transfer activity grouped by token contract, giving a clear picture of wallet activity.

HOW TO USE

Select the desired BSC network (Mainnet or Testnet) from the dropdown menu. Enter a transaction hash to view the complete transaction details including status, gas usage, effective gas price, total cost, and any BEP-20 token transfers embedded in the transaction. Enter a wallet address to view its BNB balance and a summary of recent BEP-20 transfers organized by token contract. The tool automatically detects whether you entered a transaction hash or an address. Each result includes direct links to BSCScan for deeper investigation. The wallet bridge can be used to switch networks automatically if you are connected.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to connect to BSC via either the connected wallet's provider or a public RPC endpoint. For transaction lookups, it fetches the transaction, receipt, and block data, then parses logs to extract BEP-20 transfer events using the standard Transfer event signature (0xddf252ad...). For address lookups, it retrieves the native BNB balance and then uses chunked log scanning with automatic backoff to fetch BEP-20 transfer events involving the address. The log scanner starts with 2000-block chunks and halves the chunk size on RPC rejection, ensuring public RPC limits are respected. Gas costs are calculated using receipt.effectiveGasPrice, which accurately reflects actual spend post-London upgrade.

WHAT IT CANNOT SEE

This tool cannot track cross-chain BNB transfers beyond the BNB Smart Chain—once funds bridge to another chain, they are outside its scope. It cannot verify off-chain transaction status or detect transactions that have not yet been broadcast to the network. It is limited to BNB Smart Chain data only and cannot detect tokens that do not follow the standard BEP-20 event interface (e.g., tokens that use non-standard transfer event signatures). It also cannot detect internal transactions or contract state changes beyond what is emitted in logs.

PLEASE NOTE

This tool is EVM only and specifically designed for BNB Smart Chain (mainnet and testnet). No other chains are supported. All data is read-only—no transactions are signed or sent.
