The complete guide to BscScan — the official block explorer for BNB Smart Chain (BSC), built by the same team as Etherscan. Learn how to read and verify transactions, decode smart contract interactions, track any wallet address, analyse token holder distributions, use the gas price tracker, spot red flags in token contracts, interact with contracts directly through the UI, and leverage the BscScan API for data and development work.
Look up any BNB Chain address to see its full transaction history, token balances, BNB holdings, and smart contract interactions. Verify whether a transfer arrived, check pending status, and trace funds across wallets.
Check whether a contract's source code is verified, read public contract functions and stored data, and call write functions directly from the BscScan UI — no code required for basic interactions.
View full BEP-20 token profiles: total supply, holder count, top holder distribution, transfer history, and contract details. Essential for token due diligence before any BNB Chain investment.
Use the Gas Tracker for real-time BNB Chain gas price recommendations, check network TPS and validator status, and monitor pending transaction queues to time your transactions effectively.
BscScan is the official block explorer for BNB Smart Chain (BSC) — a blockchain developed by Binance that is fully EVM-compatible and runs parallel to the original BNB Beacon Chain. BscScan is built and maintained by the same team behind Etherscan, using the same familiar interface adapted for BSC's specific parameters (faster blocks, lower gas costs, different validator model).
Every transaction, smart contract deployment, token transfer, and block on BNB Smart Chain is publicly recorded and indexed by BscScan. As a read-only tool, BscScan cannot move funds or change any state — it only displays what the blockchain already contains, making it an entirely safe research tool regardless of what you search for.
Verify transaction confirmations, check whether a token contract is verified and safe, inspect top holder distributions for concentration risk, and track the movement of specific wallets before copying their trades.
Verify and publish contract source code, use the read/write contract UI for testing, access the BscScan API for on-chain data integration, and debug transactions via the internal transaction trace viewer.
Every BscScan transaction page contains a standard set of fields. Understanding each one lets you verify exactly what happened, who initiated it, and whether it succeeded.
| Field | What it shows | What to check |
|---|---|---|
| Transaction Hash | Unique 66-character identifier for this specific transaction | Use this to look up any transaction — share it for support queries |
| Status | Success, Pending, or Failed | Failed ≠ funds lost — gas is consumed but state change is reverted |
| Block | Block number where this transaction was included | More confirmations since this block = more finalised |
| From / To | Sender address and recipient address or contract | Verify these match the addresses you expected |
| Value | Amount of BNB transferred in this transaction | Token transfers show $0 BNB — look in the Tokens tab for BEP-20 transfers |
| Transaction Fee | Gas used × Gas price = total fee paid in BNB | Unusually high fees may indicate a gas limit set too high |
| Input Data | Encoded function call and parameters sent to the contract | Decoded view shows which contract function was called and with what arguments |
Any BNB Chain wallet address can be searched on BscScan to reveal its complete on-chain history — every transaction sent or received, every token held, and every contract it has interacted with.
BNB balance, full list of BEP-20 and BEP-721/1155 token holdings, complete transaction history with timestamps, internal transactions (contract-to-contract calls), and analytics including transaction count and first/last activity date.
Look up known smart money, project team, or VC wallet addresses to monitor their activity. Patterns like large token accumulation before a price move, or wallet-to-wallet transfers before a known event, are observable on-chain before they become public.
One of BscScan's most valuable features is smart contract verification — the process of matching a deployed contract's bytecode to its human-readable source code.
| Verification status | What it means | Trust implication |
|---|---|---|
| ✓ Verified (green checkmark) | Source code published and confirmed matching deployed bytecode | Can read code — evaluate what the contract does |
| Unverified (no checkmark) | Only compiled bytecode available — no human-readable source | Cannot audit code — higher trust risk; treat with caution |
| Proxy contract | A proxy pattern — the logic contract may be upgradeable | Check the implementation contract; logic may change post-deploy |
Every BEP-20 token on BNB Chain has a dedicated token page on BscScan aggregating critical data points for due diligence.
| Metric | Where to find it | What to look for |
|---|---|---|
| Total supply | Token overview header | Compare with what the project claims — unexpectedly large supply is a red flag |
| Holder count | Token overview header | Very few holders (<100) on a "launched" token = likely pre-distribution or scam |
| Top holders list | Holders tab | Top 10 holders owning 80%+ of supply = extreme concentration risk / rugpull signal |
| Transfer history | Transfers tab | All-buy / no-sell transaction pattern = potential honeypot |
| Contract address | Overview / Contract tab | Always verify the contract address against the project's official announcement |
| LP token holder | Check the DEX LP token holders | If one wallet holds 90%+ of LP tokens, they can rug instantly |
BNB Smart Chain uses gas measured in Gwei — the unit of BNB used to pay for computational work. BscScan's Gas Tracker shows real-time recommended gas prices across three priority tiers.
The tracker shows Low / Standard / Fast gas prices in Gwei. Low confirms slower (often still fast on BSC due to 3-second blocks). Standard is suitable for most transactions. Fast ensures priority inclusion when the network is congested.
BSC gas fees are dramatically lower than Ethereum mainnet — typically 1–5 Gwei vs Ethereum's 10–100+ Gwei during peak periods. BSC's 3-second block time also means Low gas settings still confirm quickly, unlike Ethereum where low-priority transactions can wait hours.
BscScan data is the most reliable tool for pre-trade due diligence on BNB Chain tokens. The following patterns are strong warning signals identifiable directly from BscScan.
| Red flag | Where to spot it on BscScan | Risk it signals |
|---|---|---|
| Unverified contract code | Contract tab — no green checkmark | Cannot audit code — could contain any malicious logic |
| Top 10 holders > 80% supply | Token → Holders tab | Extreme concentration — coordinated dump risk |
| LP held by one address (not locked) | LP token → Holders tab | Rugpull risk — LP can be removed instantly |
| Zero sells in transfer history | Token → Transfers tab | Honeypot — contract blocks sell function |
| Owner functions: setFee, pause, blacklist | Contract → Read/Code tab | Owner can raise fees, pause trading, or block specific wallets |
| Token launched < 48h ago | Token first transfer timestamp | Insufficient track record — very high-risk window |
| Deployer wallet = large holder | Contract creation tx → deployer holds large % of supply | Team can sell into retail demand at any time |
BscScan's Write Contract feature allows you to call contract functions that change blockchain state — directly from the BscScan UI without needing a custom front-end or code. This is useful for claiming rewards, approving tokens, or interacting with a protocol whose front-end is unavailable.
BscScan provides a free API (with rate limits) and paid tiers for higher-volume access — allowing developers and researchers to query BNB Chain data programmatically without running their own node.
Account balances, transaction lists, BEP-20 token transfers, contract ABI retrieval, contract source code, gas oracle data, block rewards, and token supply info — all queryable via simple REST API calls with your BscScan API key.
Portfolio trackers, DeFi analytics dashboards, tax calculation tools, smart money monitoring bots, token launch scanners, and on-chain data feeds for trading algorithms all commonly use the BscScan API as a primary data source.
| Explorer | Chain | Builder | Unique features |
|---|---|---|---|
| BscScan | BNB Smart Chain | Etherscan team | BNB-specific gas tracker, validator info, BSC bridge tracker |
| Etherscan | Ethereum mainnet | Etherscan team | MEV explorer, ENS resolution, deepest L1 data |
| SnowTrace | Avalanche C-Chain | Etherscan team | Avalanche subnet data, AVAX-specific metrics |
| Polygonscan | Polygon PoS | Etherscan team | Polygon checkpoint data, MATIC staking |
| Arbiscan | Arbitrum One | Etherscan team | L2 batch data, Arbitrum One vs Nova distinction |
BscScan is the official block explorer for BNB Smart Chain — a read-only tool that displays all publicly recorded on-chain activity. It's used to verify transactions, check wallet balances and history, read smart contract code and data, analyse token holder distributions, monitor gas prices, and interact with contracts directly. Built by the Etherscan team, it shares the same interface conventions as Ethereum's primary explorer.
Yes — BscScan is entirely read-only for basic browsing. Searching a wallet address, transaction hash, or contract address only reads publicly available blockchain data. No wallet connection is required for viewing data. The only risk arises if you use the "Write Contract" feature to interact with contracts — that requires connecting your wallet and signing transactions, which carries standard smart-contract interaction risk.
Key checks on BscScan: (1) verify the contract code is published — no green checkmark is a red flag; (2) check the Holders tab for extreme supply concentration (top 10 holding 80%+); (3) look at the Transfers tab for all-buy/no-sell patterns indicating a honeypot; (4) find the LP token and check its holders — if one wallet holds 90%+ without a lock, rugpull risk is high; (5) read the contract code for dangerous owner functions (setFee to 100%, blacklist, pause). Complement BscScan with TokenSniffer and GoPlus Security for automated analysis.
Failed transactions on BSC are usually caused by: insufficient slippage tolerance on a DEX swap (price moved between quote and execution), gas limit set too low for the contract operation, or a contract condition that wasn't met at execution time (e.g. a transfer restriction, a deadline expiry, or an insufficient balance check). The gas fee is consumed regardless. Check the Revert Reason field on the failed transaction for a specific error message.
An unverified contract means the contract's source code has not been published and matched against the deployed bytecode on BscScan. You can only see the compiled bytecode — not human-readable Solidity code. This makes it impossible to audit what the contract does. Unverified contracts carry higher trust risk because you cannot independently verify their logic. Many legitimate projects don't verify their contracts, but for DeFi and tokens involving your funds, always treat unverified contracts with extra caution.
Search the wallet address on BscScan. The main page shows the BNB balance. To see BEP-20 token holdings, look at the "Token" dropdown in the top-right area of the address page — it lists all tokens held with their current values. For a complete transaction breakdown, the "BEP-20 Token Txns" tab shows every token transfer involving that wallet. For NFTs, the "BEP-721 Token Txns" tab covers non-fungible token movements.
Yes — any BNB Smart Chain wallet address is publicly visible on BscScan. You can monitor any wallet's transaction history, token accumulation or disposal patterns, new contract interactions, and timing of trades. BscScan's basic interface allows manual monitoring. For automated alerts and more sophisticated tracking, dedicated on-chain analytics tools (Nansen, Arkham) build on BscScan-equivalent data sources with notification features.
BscScan and Etherscan are built by the same team and use the same interface — the primary difference is the blockchain each covers. BscScan covers BNB Smart Chain (faster blocks, lower gas, different validator model); Etherscan covers Ethereum mainnet (slower, higher security, more decentralised). BscScan-specific features include BSC's 21-validator proof-of-staked-authority data and BSC bridge tracking. If you can navigate one, you can navigate the other with minimal adjustment.
Register for a free API key at BscScan's developer portal. The free tier allows 5 requests/second and 100,000 API calls per day — sufficient for most personal projects and research. The API follows the same structure as Etherscan's API (same module/action parameter pattern), so code written for Etherscan often works for BscScan with just the base URL changed. Paid Pro plans offer higher rate limits for production applications requiring higher throughput.
