Polygon Block Explorer

WHAT IT DOES

Polygon Block Explorer is a read-only blockchain analytics tool built specifically for the Polygon Proof-of-Stake network. It provides comprehensive visibility into all on-chain activity including native MATIC transactions, ERC-20 token transfers, ERC-721 NFT 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), and automatically detects and displays token transfers from transaction logs. For addresses, it shows MATIC balance and aggregates recent token transfer activity grouped by contract address, giving a clear picture of wallet activity across both fungible and non-fungible tokens.

HOW TO USE

Select the desired Polygon network (Mainnet or Mumbai Testnet) from the dropdown menu. Enter a transaction hash to view complete transaction details including status, gas usage, effective gas price, total cost, and any token transfers embedded in the logs. Enter a wallet address to view its MATIC balance and a summary of recent ERC-20 and ERC-721 transfers organized by token contract. Enter a token contract address to view its transfer history—the tool will automatically detect it as an address lookup and show transfers involving that contract. Each result includes direct links to Polygonscan for deeper investigation.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to connect to Polygon via either the connected wallet's provider or a public RPC endpoint (polygon-rpc.com for mainnet, rpc-mumbai.maticvigil.com for testnet). For transaction lookups, it fetches the transaction, receipt, and block data, then parses logs to extract token transfers using the standard ERC-20/ERC-721 Transfer event signature (0xddf252ad...). For address lookups, it retrieves the native MATIC balance and then uses chunked log scanning with automatic backoff to fetch token 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 Polygon transfers beyond the PoS chain—once funds bridge to Ethereum or other chains, 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 Polygon PoS data only and cannot detect tokens that do not follow the standard ERC-20/ERC-721 event interfaces (e.g., tokens using non-standard transfer signatures, or proxy patterns with different event emitters). 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 Polygon PoS (mainnet and Mumbai testnet). No other chains are supported. All data is read-only—no transactions are signed or sent.
