# PolygonScanner — Polygon PoS Blockchain Explorer & Gwei Telemetry Engine

> PolygonScanner is an institutional-grade Polygon PoS Blockchain Explorer, Heimdall & Bor Monitor, Address & Smart Contract Inspector, and Dynamic EIP-1559 Gas & Staking Engine (https://polygonscanner.com).

## Overview
PolygonScan powers lightning-fast exploration for the Polygon PoS network alongside universal EVM diagnostics with instantaneous search, real-time confirmed block and transaction feeds, smart contract execution tracking, ERC-20 token tracking, Validator Staking analytics, and EVM runtime error guides. Featuring 2.1s block times, 105 active PoS validators (~5.5% APY), and an efficient EIP-1559 baseline gas price in Gwei, PolygonScan provides complete transparency into the Polygon PoS ecosystem health.
